Re: problem in pylons web application
Which version of FormBuild are you using and where did you see that
example please? In the latest version there is no helpers module. I'd
suggest either installing an older version or updating to version 3
and using the Form class.
pip install --upgrade FormBuild=3.0,=3.0.99
Docs for that version are at
http://jimmyg.org/work/code/formbuild/3.0.1/manual.html
Incidentally there will be a new, rather different FormBuild in the
next few weeks with a stricter model for fields but you are better off
with the version mentioned above.
HTH,
James

Re: FormBuild3 question
Hi waugust,
Thanks. There are actually two problems here:
* A bug in form.end_with_layout()
* A bug where the example LiteralForm in the docs is out of date
I've made a new release 3.0.2 to fix them both. If you get the source
distribution and look at test/pylons_test.py you should see the
example working correctly.
Mike: Thanks for bringing this to my attention.
Cheers,
James

Re: How extensible is AuthKit?
Hi Jamie, It sounds like you already have a farily sophisticated setup so I'd recommend rolling your own but using the AuthKit code as an example for anything you wish to build yourself. One tip though, I now believe using exceptions to trigger the 401 and 403 responses and then intercepting them in WSGI middleware is not a good design pattern. New code I'm working on generates a normal response in the authorization decorators or whereever the check fails instead of in the WSGI middleware. This avoids problems with other middleware components intercepting exceptions when they aren't supposed to and also avoids issues around the WSGI middleware trying to generate a page using objects which are only available where the exception was raised. It is just less tangled so I'd recommend you avoid using exceptions in your own code too. Cheers, James (AuthKit author) On Jan 2, 2:36 am, Jamie jjbe...@gmail.com wrote: I'm working on porting an old PHP project of mine over to Pylons. For authentication this project mainly uses a lot of Postgres stored procedures. As well as checking valid login attempts, the database generates and tracks authentication tokens that are stored client-side in cookies. Each token is calculated by hashing the username, ip address, useragent, and some other stuff. Current valid tokens are stored in a db table. The cookie expiration (token timeout) is automatically updated each time the token is used, up to a maximum lifetime. If I expect to port this app over successfully, this authentication system cannot be altered at this time. I know that I can use a customized authentication backend with Authkit, but I'm not sure that it's made to be tweaked this throughly (short of essentially forking it...meh). But I do like middleware-ish features like the decorators and intercepting HTTP status codes. Should I roll-my-own solution now and maybe port it over to AuthKit down the road, or can I drop-in the functionality I need without murdering the existing code too much? -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

The Definitive Guide to Pylons (complimentary copies)
Hi everyone, I'm pleased to announce that The Definitive Guide to Pylons is now available in bookshops. If you order a copy from Amazon today you might even get it in time for Christmas! http://www.amazon.com/Definitive-Guide-Pylons-James-Gardner/dp/1590599349/ The book represents 18 months work and is the most complete and up-to- date reference to Pylons available. As many of you will know this book was written in collaboration with the Pylons community and the alpha drafts of the chapters are still available online at http://pylonsbook.com. I'd like, once again, to thank everyone who contributed for all their efforts. I really appreciate them and I've acknowledged some of the key contributers in the book itself. Over the next few weeks I'll begin updating the Pylons Book website with the final version of the text but at the moment the only way to get the complete version is to either buy the hard copy or receive one of the ones I'm giving away. Read on for details... Apress often send complimentary copies of the book to important people who are well connected at the corporate level (or in academia) and since this represents a great opportunity to spread the word about Pylons too I thought I'd ask everyone on the list for their thoughts about who it would be most useful to send these books to. If you could email me (off-list) with their names and contact details I'll take the top 5 suggestions and make sure they each receive a book. I'll also send a copy to the first person who suggests each person I eventually decide to send the books to, so please get your thinking caps on! (I've already thought of sending one to Guido so that doesn't count!) Also if you'd be willing to write a review of the final release version of the book please get in touch with me too and I'll see if I can send you a complimentary copy for review as well. More generally if you've bought a copy of the book and are finding it a positive experience I'd really appreciate it if you'd consider sharing your thoughts either on your blog or by posting a review on Amazon - you can do so by clicking the Create your own review link in the Customer Reviews section on the Amazon page above and signing in. In the past the lack of documentation has been one of the major criticisms of Pylons so if we can make a good job of advertising the presence of the book (and the official documentation Ben has been working on) I hope we can spread the word about Pylons more effectively. I know some people have started talking about the book already and it is great to see the positive comments appearing. Thanks a lot and I hope you enjoy the book, James P.S. Since the the book has made it onto the shelves before Pylons 0.9.7 is officially released I've written a guide at http://tinyurl.com/69ffjv which shows you how to use the Pylons release candidates for the time being. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

mod_wsgi is much stricter about return types than the Paste HTTP
server used during development. Something somewhere is returning a
webhelpers.html.literal object when mod_wsgi is expecting an 8-bit
string, most likely it is the template you are using for the sign in.
Try changing the pyupo.lib.auth.render_signin function so that the
value it returns is encoded:
def render_signin(...):
return template.encode('utf-8')
Then it will all work.

Re: Problems with AuthKit (was: Django or Pylons - comparison details)
Hi Raoul, Sorry, I quoted someone else, and I didn't clarify to say that I don't agree with him 100%. Faux pas on my part there, I didn't intend to be insulting. What I tried to convey was that AuthKit doesn't fit *my* needs. Sorry, I hadn't seen the earlier thread, my fault too. Not at all. If I wanted automagic GUIs, I'd have chosen Django, with all it's terrible ideas ;-). What I wanted was a auth+auth layer that worked with my table names, and worked *with* me. When I looked at AuthKit when I was starting my project about 6 months ago, it *felt* it it was working *against* me. I hear that a lot and am quite keen to get to the bottom of the problem. The problem I encountered with AuthKit when I looked at it, was that it seemed too manual. I didn't want manual, I wanted automagic. I didn't want to have to specify users or groups in my code, it needed to happen from information in the database. AuthKit has obviously progressed since then, and it looks like some of what I wanted has been developed, but when I looked at it, it didn't fullfil my needs. That's interesting. What information exactly did you expect AuthKit to be able to extract? At one level there is a Users API interface which you can abstract for whatever back end you like but that clearly wasn't what you wanted either. What sort of data did you want AuthKit to be able to work on? I'm keen to take AuthKit where it needs to be now I've mostly finished the book. One of my other problems was that the documentation was rather confusing. It didn't show me what I presumed 90% of developers would want, that being to be able to use data from a database to drive the permissions system. The documentation when I last looked at it was heavily in favour of the more manual way of doing things, with hard-coded users and and groups, and very little (in fact, I didn't see any) of the documentation discussed using SQLAlchemy models for users, groups (or roles) and permissions. Yes the docs were pretty poor. The only option was to really look at the examples. I've now written two complete chapters about using AuthKit in Pylons and they target only the core use case. It is probably too late for you now but the two chapters are here: http://pylonsbook.com/alpha1/authentication_and_authorization http://pylonsbook.com/alpha1/simplesite_part_3 There are updated versions on their way as soon as Apress send me the final texts but the current versions represent the best guide to AuthKit and Pylons. Perhaps one of the things you can look at some time is sprucing up the documentation to show how to use SQLAlchemy models to pull users, groups and permissions with AuthKit. I'm sure a lot of folks would appreciate it, and more folks would be encouraged to use AuthKit rather than write their own homegrown system. That's precisely what the two chapters just mentioned do. I hope this clears things up. I was in no way wanting to put down your effort into AuthKit. As an open source developer myself, I know how often it can be a thankless task when your code is still in it's early phases and people are demanding something you can't deliver. I appreciate that, thanks. In all honesty I know AuthKit has caused a lot of people quite a lot of pain though and I'm keen to sort it out. I'm most of the way through closing all the open tickets now and if I can get some clear guidance about the sorts of problems people have run into I'm keen to help.

Hi Eric, It isn't that it hasn't received any attention, rather that I need to be sure your patch won't break other functionality.

Re: AuthKit Newbie Woes
Hi Steven, Ben and Walter, I updated the AuthKit chapters today: http://pylonsbook.com/alpha1/authentication_and_authorization http://pylonsbook.com/alpha1/simplesite_part_3 As it happens, although the SimpleSite Part 3 chapter isn't finished, I believe all the AuthKit information is now accurate. Version 0.4.1 is exactly the same as the current SVN trunk. There are quite a few bugs outstanding against AuthKit so I thought I'd release 0.4.1 for all people currently using trunk and then start using 0.4.2 for the bug fixes but since I'm going on holiday in 4 hours I didn't want to formally release it before I left. You should just use trunk for the time being but if you really want to use 0.4.1 you can do this (bear in mind it might need to be tweaked slightly before I make it formally available): svn co http://authkit.org/svn/AuthKit/tags/0.4.1 AuthKit cd AuthKit python setup.py install I'll check it more carefully and release it once I'm back next week and then begin the work of applying tickets and updating the documentation.

Change to AuthKit setup.enable behaviour
Hi all, I've just checked in some code to the trunk which changes the behaviour of the setup.enable option to AuthKit. If you specify: setup.enable = False in a config file it used to disable the AuthKit middleware. It now also disables all the authorization adaptors too. This is useful if you want to run test suites on the code itself without having to fake all the authentication and authorization set up. I've also added a setup.fakeuser option which sets the REMOTE_USER variable so that tests can be run as if a particular user is signed in.

Re: How to make QuickWiki Integration Tutorial on pylons .9.6.1, authkit0.4 and sqlalchemy_04_driver work
The sqlalchemy_04_driver requires the SQLAlchemyManager middleware to be
set up. This basically involves setting up SQLAlchemy as middleware
rather than as part of Pylons as the QuickWiki tutorial does. You can
follow the example here:
http://authkit.org/trac/browser/AuthKit/trunk/examples/user/database/app.py
Using SQLAlchemyMiddleware isn't the standard way of doing things in
Pylons but it is the best way if you want to create middleware services
which rely on an SQLAlchemy session.
There are other SQLAlchemy Drivers which people have submitted on this
list which don't require the middleware.

Hi,
I'm trying to make QuickWiki Integration Tutorial work with
sqlalchemy_04_driver
http://wiki.pylonshq.com/display/pysbook/Authentication+and+Authorization.
I changed websetup.py in a way that is not describe in tutorial:
from authkit.users.sqlalchemy_04_driver import UsersFromDatabase,
setup_model
def setup_config(command, filename, section, vars):
Place any commands to setup quickwiki here
conf = appconfig('config:' + filename)
load_environment(conf.global_conf, conf.local_conf)
import quickwiki.model as model
# Populate the DB on 'paster setup-app'
log.info(Setting up database connectivity...)
engine = config['pylons.g'].sa_engine
log.info (Adding users and roles)
setup_model(model, model.metadata)
environ = {}
environ['sqlalchemy.session'] = model.Session
environ['sqlalchemy.model'] = model
log.info(Creating tables...)
model.metadata.create_all(bind=engine)
log.info(Successfully set up.)
users = UsersFromDatabase(environ)
users.role_create(delete)
users.user_create(admin, password=opensesame)
users.user_add_role(admin, role=delete)
log.info(Adding front page data...)
page = model.Page()
page.title = 'FrontPage'
page.content = 'Welcome to the QuickWiki front page.'
model.Session.save(page)
model.Session.commit()
log.info(Successfully set up.)
In development.ini I have:
sqlalchemy.default.url = mysql://root:[EMAIL PROTECTED]/pylons
sqlalchemy.echo = true
authkit.setup.method = form, cookie
authkit.form.authenticate.user.type =
authkit.users.sqlalchemy_04_driver:UsersFromDatabase
authkit.form.authenticate.user.data = quickwiki.model
authkit.cookie.secret = secret string
I've taken:
http://authkit.org/svn/AuthKit/trunk/authkit/users/sqlalchemy_04_driver.py
When I call:
paster setup-app development.ini
Everything is all right and proper changes in database are made.
But when I call:
paster serve --reload development.ini

environ.has_key('sqlalchemy.session'):

If I use files instead of db in development.ini everything works just
fine:
authkit.form.authenticate.user.type = authkit.users:UsersFromFile
authkit.form.authenticate.user.data = /home/keemor/pylons/
users_information.txt
I think I've digged everything about it, so please give me a clue.

Re: AuthKit problems
Hi Lythoner, Yes. I have modified sqlalchemy_driver.py file to use SqlAlchemy 0.4. Actually what I meant was that there is already an SQLAlchemy 0.4 driver in there: http://authkit.org/trac/browser/AuthKit/trunk/authkit/users/sqlalchemy_04_driver.py It uses some experimental middleware I wrote to wrap some of the SQLAlchemy functionality in WSGI middleware - this isn't the recommended approach in Pylons though so you might prefer to use your driver instead. Do you have the unit tests for sqlalchemy_driver?. Please spot me the location, I would give a try. Yes try here: http://authkit.org/trac/browser/AuthKit/trunk/test You run them using nose. I think the command is: nose test/test.py If Trac is temperamental when following the above links just press refresh a few times and it should work. I am newbie to pylons, sqlalchemy, have little programming experience in Python itself. Whatever I have done MAY NOT be correct. I have attached the modified file, which I haven't given much review. If you give me some comments/suggestions, I love to do this migration. Thanks for the offer, do you want to take a look at the existing version and see if it meets your needs first? The version I've linked above uses a new experimental version of the API which creates a new Users instance each time it is called. The methods each have access to the WSGI environ so in principle the new API should be a lot more flexible than the old one. We could add your version in too if you are confident it will end up stable? Sorry, It was SessionContext not SAContext. Ahh, makes more sense.

Re: AuthKit problems
Hi Enrico, Now the it seems that the 'sqlalchemy_04_driver' have some problem with 'environ' object. Ahh, you've been caught out by the different API used by the 0.4 driver. The first argument with the new API should be the WSGI environment. I can see why this doesn't quite work in the way you were expecting. If you do want to use this driver you'll need to setup the SQLAlchemyMiddleware first like this example does: http://authkit.org/trac/browser/AuthKit/trunk/examples/user/database/app.py Note this isn't the currently recommended way of using SQLAlchemy with Pylons, it is just the one I happen to like. You might be better off with Lythoner's version perhaps if that works for you?

Re: AuthKit problems
Hi Lythoner,
You've spotted the SQLAlchemy 0.4 driver have you? AuthKit has never
used SAContext ever.
Cheers,
James

Enrico,
AuthKit 0.4 is not updated to use the full power of sqlalchemy 0.4. I
had faced a lot of issues with UsersFromDatabase class last week.
SAContext is a hook they have added temporarily to help the session
management and reduce number of repetitive code. Now sqlalchemy 0.4 has
improved in this area. AuthKit 0.4 code is really cruft and it has to be
updated in many areas require clean up.
Myself I did some changes in the UsersFromDatabase class to use the
latest version of the sqlalchemy. I don't know whether it is good
approach or not. I just enjoy the learning curve(with frustration).
Their documentation sucks :-(.

Re: Authkit 0.3.0pre5dev_r92 + Pylons 0.9.6rc2 doesn't works?
Hi Jose,
The documentation is for AuthKit 0.4 from
http://authkit.org/svn/AuthKit/branches/0.4 I'm going to make a release
at the weekend.
The problem might be because Pylons 0.9.6 doesn't have the
httpexceptions middleware.
Try using AuthKit 0.4 and things are more likely to work.
I've put a note at the top of the chapter. Apologies for not making it
clear.

Re: Anti-cacheing headers in Pylons
You can edit your config/middleware.py file so the end of it looks like this: ... javascripts_app = StaticJavascripts() class NoCache(object): def __init__(self, app): self.app = app def __call__(self, environ, start_response): def sr(status,headers,exc_info=None): headers.append( ( 'Cache-Control', 'no-cache, no-store, must-revalidate' ) ) return start_response(status,headers,exc_info) return self.app(environ, sr) app = NoCache(app) app = Cascade([static_app, javascripts_app, app]) return app If you want to force everything to be refreshed, not just the dynamically generated pages you can wrap the whole app in the NoCache middleware.

Re: Retrieving multiple similar values from request.params
Hi voltron, I wrote a blog entry about this here: http://jimmyg.org/2007/09/19/multiple-checkboxes-with-formencode/ Basically you use a custom Schema in a ForEach validator and then use a NestedVarables pre-validator to decode the data to a list. You then need to re-encode it before using HTMLfill to re-populate your form. Your form template needs to name the variables in the correct style so that FormEncode can decode them correctly. The blog entry starts off talking about checkboxes but the bit you need is slightly further down. I'm writing a chapter for the Pylons book about this at the moment so if you need more info let me know and I'll send you the draft off-list.

Re: problem creating custom pylons project template
Your setup.py file doesn't have the paste.app_factory main entry point so the paster command doesn't know where the make_app() function of your Pylons app actually is. To fix this make your entry_points look like this: entry_points= [paste.app_factory] main=cpccpylons:make_app [paste.app_install] main=paste.script.appinstall:Installer [paste.paster_create_template] cpcc_pylons=cpccpylons.cpcc:CPCCTemplate , You might need to change the line starting main= so that it points to the correct module where you make_app() function is defined.

Re: problem creating custom pylons project template
Hi, Well I just wrote the response below which someone else might find useful in the future but in this case I've a hunch the problem is that you have chosen the name ``new`` as the test. I expect Python is importing the name ``new`` rather than your new project. Try creating a test project that doesn't conflict with an existing Python module? HTH, James Oh I see, well as I mentioned I think the error is because paste can't find the paste.app_factory main entry point for the generated package so you'll have to experiment a bit. Have a really careful look at /home/chris/pylons/new/setup.py and check the entry points are there and that you haven't specified the wrong package name by mistake in the entry_points line. If it all looks right try running python setup.py egg_info to regenerate the egg information. Can you post the actual generated setup.py which is going wrong rather than the template one as it is tricky to debug otherwise. Also make sure that the make_app() function still exists in the correct place (ie that you haven't altered package/__init__.py by mistake?). emery wrote: Thanks James, but I think I am still missing something. The setup.py I posted is for the custompylons package that contains the template directory. The application that is generated using pylons create template=cpcc_pylons then has a setup.py (generated from setup.py_tmpl) that does contain those entry points. Since make_app is actually defined in the generated pylons project, I am not sure how to reference it in the custompylons package setup.py. I've added the setup.py_tmpl I am using in the custom project to http://paste.lisp.org/display/43399#3. Forgive me if I am being obtuse, entry points and packaging are still very new to me. On Jun 25, 3:12 pm, James Gardner [EMAIL PROTECTED] wrote: Your setup.py file doesn't have the paste.app_factory main entry point so the paster command doesn't know where the make_app() function of your Pylons app actually is. To fix this make your entry_points look like this: entry_points= [paste.app_factory] main=cpccpylons:make_app [paste.app_install] main=paste.script.appinstall:Installer [paste.paster_create_template] cpcc_pylons=cpccpylons.cpcc:CPCCTemplate , You might need to change the line starting main= so that it points to the correct module where you make_app() function is defined.

Re: Revisiting Pylons Branding
Hi Tim, Maybe it's the attitude? Turn the perceived inaccessibility to Pylons' advantage and appeal more directly to the hardcore crowd. Give it a more rugged image and a bit of a bite. Use a tag line like heavy-duty rapid web development, a powerful, customizable web framework, or rapid web development for enthusiasts. It certainly fits with what I think of a pylon--a strong, proud, imposing structure. Don't bother with the our MVC, rapid development framework makes websites quicker and better than those other MVC, rapid development frameworks pack. It's a crowded field and from an uninformed perspective they can all blend together pretty quickly. Instead, emphasize Pylons' raw power and potential for customization, and in fairly aggressive terms. Say that, yes, it has a steeper learning curve, but in the end you'll have a app that you can be proud of and that's truly your own. And you can do it without the cruft of Java, the chaos of PHP, or the roadblocks of your typical MVC framework. Make it tempting for the people who want to know how a system ticks and how to get the most out of their code. Then provide the tools and resources for them to do just that I like all your suggestions and whole-heartedly agree. The brand we seem to be converging on is Pylons: Power to the developer and everything you've written neatly summarizes the ideas that tag line is supposed to represent. I'd also argue for using customizable over flexible. The former word implies more direct interaction and control. You hear about car enthusiasts customizing their cars, not their cars being flexible or adaptable (or case modders with cases, etc). It gives a better sense of Yes, I can change this system to fit my preferences and requirements. Just a personal preference, though, of course. I'm happy with that, good point. As part of the next stage I'm keen to slightly restructure Pylons so that the way the packages are organised better reflects what they actually do so that people can instantly see how customisable Pylons is by picking and choosing the best packages. The bullet points for me, as far as feature set goes: 1.a. Rapid development and MVC (which applies to just about everything post-RoR) 1.b. A second generation modern web frameworks, building on ideas from Rails, Django, etc, and learning from their flaws 2. Designed for customization; modular, configurable at any level 3. Leverages the experience and power of more specialized libraries: Paste for low-level WSGI/HTTP, Mason-Myghty-Mako, SQLAlchemy 4. Good tools for testing and debugging I like the idea of calling it a second generation framework in particular but all your points are valid. I don't typically post unless I feel it's something that hasn't been said and might benefit the project or the community. Hope my comments are useful in that regard.

Re: Pylons Security
Hi all, Who says AuthKit is not ready for production? Did its author disrecommend it? Well, I say it isn't ready for production on the main site because I'm still tweaking the APIs a bit and have written the full documentation. I'm using the 0.4 branch in production systems myself though so it should be considered ready for production if you can work out how to use it without full documentation. The 0.3 release is a bit out of date now so I hope to release the 0.4 version fairly soon. I took a quick glance at the manual and it says. AuthKit has not been audited by a security expert, please use with caution at your own risk (or better yet, report security holes). But the same goes for a lot of reasonably safe Python software. Of course it would be good to hire a security specialist to audit Pylons and its commonly-used dependencies -- are you offering to do this and file bug reports? Exactly, it should be safe but I haven't gone through all the algorithms and specs to check and I don't guarantee there aren't bugs. Does pylons have the means to keep the bad guys out? I'm interesting in using it for an e-commerce app, and you anyone can the security requirments any e-commerce app would need. You can run Pylons and AuthKit behind an secure server and then things should be pretty secure. You might be interested in my article here: http://docs.pythonweb.org/x/ZIAI The main vulnerabilities derive from the type of authentication chosen: plaintext password file, encrypted password file, SQL database, LDAP, etc. Each of these imply certain vulnerabilities that really overshadow how well AuthKit manages them. Meaning, AuthKit probably does a reasonably good job, but the factors outside its control are the ones most likely to bite you, and these should be looked at no matter whether you use AuthKit or some other library. +1 Cheers, James --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Pylons Logo Design
Hi all, Dan wrote: I think you should consider changing domain names. I don't think the name Pylons is bad, just combined with the domain pylonshq.com it just doesn't stick. I'd suggest using pylonsframework.org for the following reasons: .org - Eludes to an open source/non-profit. If Pylons is open source/non-profit I think its a feature that you should mention to your visitors... I didn't see licensing information anywhere on the homepage? pylonsframework - Eludes to Pylons being a framework right in the domain. I'd click on a URL for pylonsframework.org before pylonshq.com. My view is that we shouldn't change domain names unless we can get pylons.org or pylons.com, both of which I will continue to investigate. There is no point in changing domains because it will simply cause problems with existing links. Even though Ben has registered pylonshq.org I don't think we should change for this same reason. Also I know tech people like .org but lots of business people think .org is what you get when you can't get .com. I know it is ridiculous but I have an easier time selling Pylons as a attentional product when it is hosted a .com address compared with a .org so I'm keen to keep it that way if possible. I agree with Ben that we should add some sitemap data and mention Headquarters somewhere, people often ask what the HQ stands for. In general, the things that brought me to Pylons was the 1) speed and libraries of Python and 2) MVC development. Both are not even mentioned on the homepage. It should be in the first paragraph. WSGI seems important, even if I didn't know why, but not a reason I'd choose Pylons over another framework. Its not something that I would say in the first paragraph. I'd say that most people care about two things: speed (both development time and application performance) and stability. These two key points should be the focus of the introduction, to grab the visitors attention. I do think Pylons is flexible, which can be a feature, but it can also be a hindrance... especially for newbies. Thats tricky. I hate to mention the word, but 'screencasts' is almost a standard. It wouldn't hurt if someone could put one together. I hope that I'm not coming off as being overly critical. Pylons is a great framework. Keep up the good work! Really appreciate the comments, very helpful! Just thinking about the possibility of an Egyptian theme for the logo but temple Pylons don't look visually too exciting either. I'm open to the idea of changing the name of the project actually but only if people have very compelling alternatives and the whole community gets totally behind the idea. By the way I've added some notes about the discussion to this page: http://docs.pythonweb.org/display/pylonscommunity/Pylons+Logo If anyone wants to get started on some sample text for any of the website pages feel free to create a page off the one above and make a start! We can always move pages around to a more appropriate location later if necessary.

Re: AuthKit bails out on Unicode usernames
Hi Christoph,
I've just tested AuthKit 0.4 with an Arabic username and yes, there is a
problem because the browser encodes the Arabic as HTML entities because
there is no charset specified when the form is produced. Other than that
it all seems to work fine. Is it considered standard practice to allow
non-ascii usernames though? Particularly since usernames are supposed to
be case-insensitive in AuthKit?
I'm adding functionality now so that the default charset is UTF-8 and so
that you can arbitrarily set it but I suppose to be totally future proof
you should be able to add any status and headers you like to override
the defaults AuthKit uses. The thing is I'm not sure that isn't taking
things too far, after all, people can always implement their own middleware?

Re: AuthKit bails out on Unicode usernames
Hi Christoph,
If you use the latest AuthKit 0.4 and specify:
form_charset=UTF-8
to the authenticate middleware you should find your unicode strings work
OK. You'll need to make sure your Python source files are properly
encoded though so the users information correctly picks up the unicode
usernames - I'm not sure whether specifying them directly in the paste
config file will work for unicode for example.

Hi Frederik,
Is this now resolved with Ian's new FormEncode release? If not, can you
send me some code that breaks and I'll look into it.
No, it's still broken. The code is simply from the pylons guide for
FormBuild: http://formbuild.org/docs/pylons.html
All works fine with pylons built-in form validation as described in
http://pylonshq.com/docs/0.9.4.1/form_handling.html:
def form(self):
return render_response('/form.myt')
@validate(schema=model.form.EmailForm(), form='form')
def email(self):
return Response('Your email is: %s' %
self.form_result.get('email'))
When the email address is missing an at-sign, I get this message: Eine
E-mail Adresse muß ein einzelnes @ Zeichen enthalten
(Which is, by the way, outdated German, as we now write muss instead
of muß.)
But with the FormBuild code, I get a UnicodeEncodeError. All messages
that contain no non-ascii characters work fine. But the one stated
above (containing 'ß') breaks:
def email_form(self):
if len(request.params):
try:
results =
model.forms.schema.EmailFormSchema.to_python(
dict(request.params),
state=c
)
except formencode.Invalid, e:
c.form = model.forms.build.StandardForm(
dict(request.params),
e.error_dict or {}
)
return render_response('/email_form.myt')
else:
return Response(
'Your are %s years old and have the following
email: %s' % (
results['age'],
results['email']
)
)
else:
c.form = model.forms.build.StandardForm()
return render_response('/email_form.myt')
This gives me:
Error:Error(UnicodeEncodeError): 'ascii' codec can't encode character
u'\xdf' in position 22: ordinal not in range(128)
File: /usr/lib/python2.4/site-packages/FormBuild-0.1.6b-py2.4.egg/

20: def entry_end(self, name='', error='' ):
21: return /td
22: td valign=top%s/td
23: /tr\n%(error)
24:
So I thought it might be rather a FormBuild problem than a FormEncode
one. But I might be wrong, anyway.
Thanks for looking into this!

Re: formbuild Custom Form
Hi, FormBuild forms aren't really designed for you to do that.

Re: FormBuild doesn't handle FormEncode's unicode messages
Hi Frederik, Is this now resolved with Ian's new FormEncode release? If not, can you send me some code that breaks and I'll look into it.

Re: AuthKit: how to use authorization in Myghty templates?
Hi Chris, You need the authorized() function which returns True or False rather than raising the exception. http://authkit.org/docs/module-authkit.pylons_adaptors.html Hope that helps, James something like: Chris Shenton wrote: I'm using AuthKit with an SQLite DB and wrote a couple authorization checking classes like: class RoleIn(Permission): Does the user have a role in the supplied list of roles (logical OR).

Re: formbuild questions
Hi Cliff, Just to clarify, FormBuild isn't going to be deprecated, discontinued or merged as such, I'll continue to maintain it, but as ToscaWidgets becomes more stable I'm going to recommend people use ToscaWidgets instead of FormBuild because it provides a more natural development model and it makes sense for the Pylons community to share as much work with the TurboGears developers as possible. Also widgets are easy to share so if we all put our efforts into ToscaWidgets everyone stands to benefit from having lots of useful reusable components.

Re: AuthKit using database for users, groups, roles?
Hi Pauli, I always implement my own database, permissions and valid() function in my code. The users API is simply meant for use in small systems where there isn't any need for a more sophisticated solution. Although you could create your own implementation of the API to use a database, it is really just as easy to start from scratch and use the lower-level tools AuthKit provides. Cheers, James I've also been wondering what is the best way to use Authkit when the user database is an external one. There's this page [1] about how to make Authkit forward authentication and authorization fully to your application. One way so seems to use this forward method, and handle all authentication and authorization by yourself, [2] i.e., implement the login/logout actions, and on start of each request put the user info to c.user, for example, based on environ['REMOTE_USER'] (which is set by Authkit). It's quite easy to write your own set of authkit Permissions for checking whether user is in given group or has a given role. But I'm not really sure whether this is the best way to go, or would it be more sensible to leverage Authkit's user system. A starting point for this seems to be the authkit.users.object other config settings [3] that allow defining a custom class that implements the authkit user database API custom password validation. [1] http://pylonshq.com/project/pylonshq/wiki/PylonsWithAuthKitForward [2] http://authkit.org/docs/manual.html#manually-handling-user-management [3] http://authkit.org/docs/manual.html#using-the-user-management-api -- Pauli Virtanen --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: paste.recursive.include
Hi Ksenia
The problem here is that the recursive middleware can only forward to
paths below it. In this case, the recursive middleware is setup in the
error document middleware in the myproject app so when you try to
include /someapp the recursive middleware thinks you mean /someapp below
myproject, not /someapp below the root URL.
To fix this you would need to setup recursive middleware above the
composite app you've setup by adding a recursive filter. I don't know if
it is possible to put a filter before the composite:main section in the
config file itself but depending on how you are serving the file you can
do something like this:
from paste.recursive import RecursiveMiddleware
from paste.deploy import loadapp
app = loadapp('config:/path/to/config.ini')
app = RecursiveMiddleware(app)
if __name__ == '__main__':
from paste.httpserver import serve
serve(app, port=8000, host=0.0.0.0
I haven't tested this so let me know if there are any problems.
If you give me some more detail about what the inter-application
templating system is for I might be able to give you some alternative
suggestions? The simplest solution would probably be to just create a
python module which handles the templating calls and can be imported by
both applications.
Hope that helps,
James

Re: paste.recursive.include
Hi Ksenia,
The ErrorDocuments middleware also uses the recursive middleware so you
don't need to include it again.
Other than that, if you are trying to display the redirected page you
need to do this (I've tested it with Pylons==dev and it works fine):
def index(self):
result = request.environ['paste.recursive.include']('/someapp/test')
return Response(result)
The reason the 404 is generated in your code is likely to be because
/someapp/test isn't a valid path in your application. Try typing it
directly into the address bar and see if it gives a 404 there too perhaps?
Does the index.html file your code returns actually exist? Perhaps that
is triggering the 404?
Hope that helps,
James

From the Paste documentation:

When you call environ['paste.recursive.include'](new_path_info) a

It doesn't seem to work for Pylons, I think this key is already used for
some internal Pylons stuff. So I added RecursiveMiddleware to middleware.py:
app = RecursiveMiddleware(app, global_conf)
The problem now is that 404 error is raised whenever I call it:
class MainController(BaseController):

Re: mod_proxy example
Hi wyatt, That's exactly right. For completeness if these modules aren't already enabled can enable them with this: sudo a2enmod proxy sudo a2enmod proxy_http sudo a2enmod proxy_connect The only complication with the proxying approach occurs if you are proxying to an application that isn't at the root URL but was written to be served from the root URL. For example say your virtual host config has this in: ProxyPass /forms http://localhost:5000 ProxyPassReverse /forms http://localhost:5000 In that case you just need to tweak your development.ini with a proxy-prefix so that it all behaves as if it is being served from /forms even though it was written to be served from /. All the routes URLs, etc will be automatically adjusted.

Re: Deplyoing Pylons applications as Debian packages?
Hi Christoph, I think there are two issues here: 1. People like to install multiple versions of the software on the same machine 2. Python software, pylons included, isn't as stable from version to version as most of the software in Debian stable Although Debian packages are brilliant when you want a system-wide installation of a particular piece of software, they are less good when you want multiple versions of the same software installed on the same machine. A lot of the arguments you've made also make the assumption that any Debian package is going to be stable from one release to the next due to the efforts of the maintainer to ensure a smooth upgrade path. That works fine for system packages but seriously, Python software develops at a much faster rate than say Apache and whilst we try to maintain backward compatibility in Pylons, there are still one or two very small incompatibilities along the 0.9.x branch which I do not believe could easily be solved by a package maintainer because otherwise we would have solved them ourselves in the first place! The truth is that incompatibilities between different versions of Python software aren't *solved* by the packaging mechanism so Debian packages can't be better in that regard than using easy_install. The issue really boils down to which system you understand better. For most people who understand easy_install *and* the Debian package management system, easy_install with workingenv or a virtual Python install is the best approach and the one we will continue to recommend. As I mentioned in my first email though, if you can find a way of neatly packaging a virtual Python install or a workingenv install into a Debian package, that might be a good compromise between the two!

Re: Deplyoing Pylons applications as Debian packages?
Hi Christoph, thanks for your point-of-view. I hope mine isn't seen as trolling. I'm seriously trying to find a way to unite both the easy_install and the deb-package world. And at the moment everybody just seems to defend their own position. Many Python developer probably don't even care for Debian. :) No, I understand, there are pros and cons to both approaches. Why is that needed in reality? To try out the newest features? Or are there really multiple applications on a server where each one uses different versions of software? Well, for example I have authkit.org, formbuild.org, 3aims.com, pythonweb.org and a load of test applications under 3aimsapps.com all running on the same server. I updated authkit.org more recently than 3aims.com so it runs a different version of Pylons. Because there are minor changes between different Pylons versions it is handy to sandbox each installation so that I can start a new project with the latest Pylons without changing the software used by the old ones which I've tested and know works. I'm running Debian's unstable branch at home which means having mostly the same versions of Python modules installed that are in the CheeseShop - just as Debian packages. That's fine then, you just have to make sure all your application are constantly modified so they work with whatever is in unstable at any particular moment. That could be tricky though because those packages will probably change fairly often. I prefer to sandbox each Pylons app in its own virtual install so each app can use whichever versions are most appropriate for it. That way I don't have to worry about ensuring I'm always using the latest software for each app but I know that the app is using the software I tested it with. It is really just the most pragmatic approach. The application I am currently about to write should be running for years (at least a Debian stable period which is 1-3 years) without having to bother about new Pylons versions. So my intent is to use the current Paste version and the current Pylons version (and what else is needed). Great, well use a virtual Python install with easy_install and you won't have to worry about it again because the Pylons dependencies are kept separate from the constantly changing versions in Debian unstable. I understand that. But wouldn't it be feasable to just use a set of packages that are considered stable _now_ and use them for the next time? Yes but it is up to you which ones you consider stable for your purposes. By using a virtual Python install and easy install you can make that decision based on your needs rather than having to use whatever the Debian packagers decide is best. I know a few web developers who prefer a stable API over the newest features. When working with Pylons I currently get these annoying deprecation versions because the version of Pylons here didn't work with the newer Paste version. If I had the old versions installed I didn't have to deal with such issues. Well, if you used a virtual Python install and easy_install you could just setup your application to use the old version of Paste that doesn't have the warnings. It is about control being in the hands of the developer (who knows what is best for their application) rather than in the hands of the package maintainers. That's right. The pace is a bit slower if you stay with Debian stable. But there is a time that you surely update the software and then applications may break. At least during that period nobody has to expect surprises. But it works on an a very long cycle, the release cycle for Pylons is about 3 months max with lots of changes to the dependencies along the way so the Debian model doesn't fit projects like Pylons so well. That's not to say we won't eventually or either to imply the Debian approach is better, they are just different. I'll start working with it and see if that's feasible. That approach surely has advantages. You always have the newest version if you like. And you don't have to create another package from something that looks like a package already. Let me know if it works! Say, is there a way to package a Pylons application with all dependent packages into a single egg? I mean... if there would be an easy way to distribute an egg that creates a workingenv without interfering with the rest of the system that is at least one valid approach. I don't understand why you'd want to do this. You can specify the *exact* dependencies you wish to use (down to the version number of an SVN checkout if you like) in your setup.py file and they'll be automatically installed with easy_install so you always ensure the exact dependencies your app needs are installed anyway. You can even specify that easy_install should install the required eggs from your server rather than the cheeseshop you can guarantee your packages are going to be installed. You will
Re: Deplyoing Pylons applications as Debian packages?
Hi Christoph, I use Debian and the way I deploy my apps is using a virtual Python installation into a user account I setup for each app. I usually then just checkout the latest source code and run: ~/bin/python setup.py develop The problem with trying to package up a Pylons app into a Debian package is that you have to worry about all the dependencies. You could package up all the dependencies too but that would be a pain. I suppose the alternative solution if you really want to use a Debian package is to setup workingenv and then make a package out of the entire workingenv directory with the dependencies included as part of the one package. I've always been happy to stick to using easy_install and eggs myself but when packages have C extensions the benefits of creating .debs become more apparent. Also it is useful to have different packages available to different Pylons apps and if you just use .debs to install software into the main Python directories you can't do that. I'd be interested to hear if you come up with a good solution though? Cheers, James Christoph Haas wrote: Dear list, I'm spending some of my spare time as a Debian developer which means creating Debian (binary) packages from software. In Debian you don't use easy_install to install Python modules but rely on packages that the distribution provides. E.g. to install Pylons and all it's dependencies you issue an aptitude install python-pylons which means that certain other packages are installed automatically: python python-routes python-myghty python-paste python-pastedeploy python-pastescript python-formencode python-simplejson python-webhelpers python-nose python-beaker Naturally I wondered how to properly deploy a self-made Pylons application on Debian. Perhaps someone with more insight of the Paster deployment process can help understand what's going on and whether that can be scripted to make it a Debian package. Or perhaps other readers who are familiar with Debian package have an idea, too? I could imagine a tool like pylons-buildpackage which creates a Pylons application and makes a proper Debian package of it that can be apt-installed. I'm eager to hear other people's ideas on that. For those not being involved into Debian package management: a Debian package takes the (upstream) software itself (usually a software-1.0.tar.gz file) and adds a special debian/ subdirectory that contains control information on the page. Such information deals with copyright, what other packages are needed (as stated above), which files are to be put where in the file system and a Makefile/shell script that is run to make the software (like ./configure; make; make install). I'm also interested in how other Debian users deploy Pylons applications. Do you just copy the project directory onto another computer? Or do you deploy into /usr/local? Or am I the only one using Debian here? :) Kindly Christoph --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: ANN: AuthKit 0.3.0pre4
Hi Cliff and Robert, There was a simple typo in 0.3.0pre4 which meant none of the config data was getting passed correctly to the middleware. Thanks for pointing it out. I corrected it and released 0.3.0pre5 so you should upgrade to that. It isn't an issue with your application Cliff! To add another data point, I upgraded to svn version 57 (pre5?) from v43 and it all worked as expected. It even appears to have corrected an intermittent problem someone reported while testing where the authkit cookie was being set to an empty string, using a host with a leading dot in addition to an existing authkit cookie set to the correct value, using a host w/o a leading dot. I hadn't had a chance to try and chase down this issue, so having it go away is a good thing. FWIW, I'm using forwarding along with RemoteUser() and middleware. The cookie handling was tweaked a bit too a while ago and has some extra options now including server side expiring and including the client IP. The middleware also removes the cookie if it has a bad digest rather than raising an exception. There is OpenID authentication support in this version too.

Re: Fast Python webserver
Hi Robert, Ian I'm going to be doing some performance tests on my setup in the next few days, but one thing I've noticed in preliminary playing is that using fastcgi/flup with nginx is noticeably faster than a straight proxy. I've been interested to see how well Pylons works with Nginx and FastCGI too because I've heard lots of people say good things about the setup. On my server with a fairly simple app, using Nginx 0.4.13 to proxy to a paste http server takes about 11.5ms per request (over 1000 requests). With Nginx and FastCGI the same app took about 51ms per request. Using the paste without the proxy takes about 10.6ms per request. Unless I've set something up very wrong, that means that there is about a 1ms overhead using Nginx as a proxy compared to doing the requests directly but that using HTTP is about 5 times faster than using FastCGI. Should I be using a different version of Nginx? I would say though that Nginx is very easy to setup and I do like it, even if the FastCGI setup doesn't seem faster than the HTTP setup with Pylons. FastCGI doesn't seem substantially easier to parse than HTTP, so I'm not sure why that'd be. Maybe flup is just faster than paste.httpserver. Or maybe there's something different about the way connections are handled (are FastCGI connections persistent in any way?). I would have been surprised if the FastCGI version was faster too, and in my tests it isn't. I'd be very interested to hear your results though Robert. Cheers, James P.S.

Re: Fast Python webserver
Hi guys, Maybe you could try with the latest (0.5.12) version? I've rerun the tests with 0.5.12 and the difference is exactly the same. FastCGI is 5 times *slower* than simple HTTP! Well by default nginx is going to cache the proxied server's response before sending it to the client, that could explain the 1msec or so. I'm sure you'd have different results over a slower link where it makes more sense to do that kind of caching. I'm not so worried about the 1ms difference. There is bound to be an overhead adding another component to the stack. What does seem strange is that people are claiming FastCGI performance is better than HTTP performance when in my tests the HTTP performance is 5 times faster! I'm sure there's things that can be done to paste.httpserver to make it come closer to FastCGI in performance. Hang on a sec, FastCGI is 5 times slower than HTTP, surely it is the FastCGI implementation that requires improvement? Maybe. I'm going to be investigating fapws (and perhaps CherryPy's WSGI server as well) to see if there's any significant gain by using those rather than paste.httpserver (although I suspect most of the overhead is in the framework and application, not the HTTP server itself, so even significant gains in HTTP performance might not add up to much overall) Again, my tests clearly show HTTP is 5 times faster than FastCGI. Am I missing a trick? Cliff: Do you still have the links to the benchmarks you mentioned, I'd be interested to see the setup being tested. Perhaps you are proxying to multiple FastCGI backends which is of course going to be faster than a single HTTP backend but you can also proxy to multiple HTTP backends so that isn't comparing like with like. I'd really like to get to the bottom of these rumours because if there is a faster way of serving a Pylons app I'm keen to document it so that everyone can benefit.

Hi Ian, I've rerun the tests with 0.5.12 and the difference is exactly the same. FastCGI is 5 times *slower* than simple HTTP! Someone mentioned caching -- are you sure that the HTTP server is getting all the requests? If Nginx is caching some responses and not passing them through, it will of course be much faster. Yes, I'm sure there is no caching when using HTTP because I can benchmark the paste server directly and it is about 1ms faster per request than using Nginx to proxy to it. Perhaps you are proxying to multiple FastCGI backends which is of course going to be faster than a single HTTP backend but you can also proxy to multiple HTTP backends so that isn't comparing like with like. It shouldn't dramatically improve performance to use multiple FastCGI backends. Unless you have a SMP machine or something, which could change performance in all kinds of ways. Fair point, but it depends a bit on what is going on that is making the FastCGI performance so poor.

Re: Fast Python webserver
Hi Bob, I'm curious as to why anyone would want to use FastCGI in the first place if proxying is available? Implementation wise, there's very little reason why FastCGI would be markedly faster or slower than the HTTP protocol. Agreed, there's no point unless FastCGI is significantly faster which would be unexpected. Since the tests show it isn't faster I'm going to carry on using my existing HTTP setup. We can put the FastCGI rumour to bed. Cheers, James --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Robert Leftwich wrote: As I'm the one that said it was faster earlier in the thread, I think I should be the one to put the rumour to bed :-)) Sure. I've heard the same rumour in other places too though actually, particularly related to rails but also with Pylons eg: http://www.rkblog.rk.edu.pl/w/p/pylons-benchmark-various-servers/ As mentioned in the earlier post, I was playing around with some preliminary configurations on my laptop and it was faster using flup/fastcgi (via ab, not wall clock). Interesting. I was using ab too. I have been waiting for another server to be setup side by side at my hosting company before I did any 'real' testing, as any testing done outside the host network just saturated the b/w I had available from my office (nothing faster than 128k ISDN where I live/work) w/o getting the server warmed up. OK, I was testing on localhost. I probably should have just kept my email shut until doing some real testing - stay tuned. I look forward to the results.

Re: AuthKit and AuthDemo
Hi Hamish,
I need some simple cookie-based authentication: the user should
initially be presented with a page asking for their email address; an
email should be sent to that address containing a link; when the user
visits that link, an association is made between cookie and email
address. If the user subsequently deletes the cookie, they will get a
new one and will need to associate it with their email address again
in the same way.
Would AuthKit be suitable for this? Would something more lightweight
be better?
AuthKit is extremely light-weight although there isn't any code that
does exactly what you are after built in so you will have to read the
manual and decide the best way to integrate the cookie middleware in
authkit.authenticate.auth_tkt into your application.
Also, I tried to install AuthDemo but get:
pkg_resources.VersionConflict: (web 0.6.0 (/Library/Frameworks/
Python.framework/Versions/2.4/lib/python2.4/site-packages/web-0.6.0-
py2.4.egg), Requirement.parse('web=0.6.1,0.7'))
I can't find web0.6.0, and neither can easy_install. It's a bit
difficult to google for a package called web, can anyone point me to
where I might find a later version?
Sorry, it is part of some legacy code I wrote at pythonweb.org. You can
install it with:
easy_install -f
http://pythonweb.org/eggs/http://pythonweb.org/eggs/web-0.6.1-py2.4.egg
The AuthDemo might be a bit sophisticated for your needs since it
includes a full registration and permissions system but it might give
you some ideas for your own app.
HTH,
James

As luck would have it I was documenting this yesterday around line 844 here:
http://pylonshq.com/project/pylonshq/browser/Pylons/trunk/docs/internationalization.txt?order=name
You can do something like this to extract strings, if you give it a go

Another question however:
Is request.environ['HTTP_ACCEPT_LANGUAGE'] the best way to get access
to the languages acceptable to the browser?
This is what I get when I execute the above:-
en-GB,en;q=0.9,en-us;q=0.8,en-US;q=0.6,ar-AE;q=0.5,ar;q=0.4,en-gb;q=0.3,en;q=0.1
Is there a further breakdown or list or should I parse the line manually?
request.environ.languages returing a list would be cool.
The list for the above might look like
['en-GB','en',en-us','en-US','ar-AE','ar','en-gb']
leaving off the duplicate 'en' off the end.
Believe it or not you are in luck again. Ben has just implemented this.
If you upgrade to the latest paste and pylons dev you should be able to
access all the languages as request.languages.
One other thing I implemented yesterday, but have yet to test properly
and write up, was language fallbacks so that if a word doesn't exist in
one catalog you can look it up in a fallback or the source instead. This
means you can setup fallbacks for all the languages in
request.languages. You'll need Pylons dev again but here's how it works:
from helloworld.lib.base import *
from pylons.i18n.translation import add_fallback
class HelloController(BaseController):
def index(self):
h.set_lang('en')
add_fallback('es')
return Response(_('Hello')+' '+_('World')+_('!'))
If Hello is in the en .mo file as Hi, World is only in es as
Mundo and none of the catalogs defined ! you will get the english,
spanish then the source words. So the message would be Hi Mundo!.

James

Is there is a way to setup this in config file?
E.g.: lang = ru en
Well, you can do lang=en already to specify the main language but it's a
good idea to able to specify the fallbacks too, I'll implement that.
If not, how can I setup this fallback globally? Add this to
BaseController?
Best place is probably the __init__() method of the Globals object in
lib/app_globals.py actually. I'd have thought it was best not to do it
in a controller action like I described above otherwise you will be
adding numerous fallbacks. I'll also write some code so that fallbacks
are only added if they aren't in place already.

Re: AuthKit: support for encrypted passwords
Hi Josh,
Josh Heitzman wrote:
I dug around a bit. What Unix systems used to was called crypt. Some

considered to be bcrypt, which includes a 128-bit salt and uses are

A python implementation of bcrypt can be had here
http://www.mindrot.org/projects/py-bcrypt, but pehaps all AuthKit needs
a mechanism for the client to specify a function it should call to
compare a submitted password to a stored password. By default AuthKit
would supply a function that just did a straight comparison, keeping
the default behavior as it is now, but allowing the client to override
that with whatever password encryption scheme they prefer.
Sound reasonable?
This already exists actually. You just need to specify a custom
valid_password() function (or digest_password() if you are using HTTP
digest).
It is documented here:
http://authkit.org/docs/manual.html#basic-http-1-0-authentication
Since you mentioned bcrypt, here's an example I expect would work:
from authkit.authenticate import middleware, test_app
import bcrypt
def valid(environ, username, password):
if not environ.has_key('authkit.users'):
raise Exception(You haven't setup any users)
users = environ['authkit.users']
if users.passwords.has_key(username.lower()):
hashed = users.passwords[username.lower()]
return bcrypt.hashpw(password, hashed) == hashed
return False
app = middleware(
test_app,
method='basic',
realm='Test Realm',
users_valid=valid
)
from paste.httpserver import serve
serve(app, host='0.0.0.0', port=8080)

Re: Authentication and Authorization Systems
Hi Uwe, Here is a complete Pylons auth system using SQLAlchemy and OpenID to get you started: http://authkit.org/trac/browser/AuthKit/trunk/examples/pylons/AuthDemo I've looked at the above example and I was wondering why there appears to be 3 separate persistence tools namely DBUtils, MySQLStore and SQLAlchemy? Is there a reason for this or am I wrong? Well, the OpenID libraries don't use SQLAlchemy so I thought I'd have a separate connection for them. The DBUtils are used to strengthen the MySQLdb connection because I found it regularly disappeared if it wasn't used for 8 hours. As it happened using DBUtils didn't help, so yes DBUtils could go. I'd still like to keep SQLAlchemy and OpenID separate though. Do you have any plans to extend AuthKit to be an OpenID server? Well I've written an OpenID server supporting the simple registration protocol (see http://passurl.com) but haven't had a chance to tidy up the code for a release yet. I wasn't planning on adding it to AuthKit though, but if you want to be involved, perhaps drop me an email off list?

Re: [AuthKit] fallback for no cookie support, AtomPP in a forward auth app
Hi David, I agree it would be handy to have a way for the app to test for the client's ability to use cookies but I think the fallback mechanism needs to be thought through to be a little more generic. I was discussing this with someone else a while back too so I'll try and find the thread. In the meantime I've added it as a ticket. http://authkit.org/trac/ticket/8 Cheers, James David Smith wrote: Hi, I'm trying to integrate Atom publishing support in my blog app which already uses authkit with the forward method very nicely. I'm thinking about how to handle the authentication on the AtomPP side, and in general what to do if the client doesn't support cookies, and would like to hear other's thoughts (especially James) regarding run-time configuration of authkit. I've attached two patches [1], [2] to authkit. The first makes it automatically test for cookie support. The second adds support for a authkit.cookie.fallback = [basic | digest] setting in the config file that will be used when the browser does not have cookie support. The result is that by specifying a cookie fallback to basic and authkit.users.valid to a simple function to do the checking, the rest of my app shouldn't need any modification for authentication purposes.

Re: how to build a portlet style site?
Hi Paul, I'm developing a new templating system called art which handles this particular case. Instead of using a controller to call a template and display the result, the template effectively defines which content it requires and calls the different controllers (called plugins in art) automatically. The individual plugins can run on multiple servers so that content can be pulled in from remote locations and all the fetching is done in parallel with threads so performance is pretty good. There are some other features too such as the ability to define templates from layout objects so that the people making the templates don't necessarily need to know HTML, they just choose a header, footer and two columns say. If you are interested I'll try and put the latest code up in the next few days. Of course, in Pylons you can always have a single controller call actions from other controllers (they are just WSGI applications) and then assemble them yourself? Cheers, James Hi all, coming from the world of plone... All the example code uses a single controller per page, which is all good and fine for crud operations on a database, but seems rather limited for what we do. I'd like to build a website (read a typical portal site) that brings together several controllers/views into a single page (i.e. /doc/view/123, /news/latest, /user/list, /user/view/myid) How to do this in pylons? Is this a templating issue? Is it possible to render a template fragment using a different controller? thanks a lot for our insight. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Authentication and Authorization Systems
Hi Alagu, All of them will work! I'd recommend AuthKit because I wrote it with Pylons in mind. I'm biased though ;-) AuthKit is based on paste.auth so includes some of the paste.auth middleware. I also tried to ensure it does everything that barrel does. Here are the AuthKit pylons docs: http://authkit.org/docs/pylons_authentication_and_authorization.html Here is a complete Pylons auth system using SQLAlchemy and OpenID to get you started: http://authkit.org/trac/browser/AuthKit/trunk/examples/pylons/AuthDemo I'm updating AuthKit all the time so let me know if you have any problems!

Re: Can Pylons be more aggressive ?
Hi Kendall, I've talked to James about writing a piece about Pylons when it goes 1.0, and I still want to do that (i.e., if James is still interested, he's got dibbs on the main 1.0 piece). I'm still up for that. In fact perhaps now that others on the mailing list seem to think it is time to start pushing Pylons more heavily perhaps I should get started!

Re: Problem with the Flickr tutorial
I just noticed that there was a change in Paste 1.1 which might affect things: paste.request.parse_formvars didn't accept parameters in CONTENT_TYPE. prototype.js sets a charset parameter, which caused a problem. Have you tried upgrading to Paste 1.1? Does that fix the issue or is it totally unrelated?

I don't understand why you'd ever want to do this? It only ever gets
called if the URL maps to a directory and if that is the case it should
return a 403. I'll change it.
It doesn't seem to have reasonable behavior when a StaticURLParser
instance is asked to serve itself, not a subfile. Probably it should
return 403 Forbidden in that case
Should it do this rather than 404? I only ask because it is used in the
config/middleware.py Cascade and if a 403 is returned, other parts of
the app won't get called but if this is the correct behavior that's fine.

os.path.normpath do this replacement on Windows? That seems like
a more
ideal solution. I'm guessing the reason it isn't working is when it

the backslash/slash confusion causes the problem. That should
probably
be updated to at least give a slightly more useful not found message
(via the optional debug_message argument to not_found).
Since you are on Windows, can you try these things out?

Re: pase 1.1 troubles (solution)
Hi Ian,
self.directory = os.path.normpath(directory)
I think that makes sense.
Great.
This is how subdirectories are handled:
SCRIPT_NAME=''; PATH_INFO='/foo/bar/baz.html'
maps to app StaticURLParser('/www')
That in turn forwards the request as:
SCRIPT_NAME='/foo'; PATH_INFO='/bar/baz.html'
maps to app StaticURLParser('/www/foo')
And so forth, until you get to a real file.
But if you end up at a directory instead of a file, it isn't working.
Ahh right, makes sense. I'll try and track down the problem.
404 would be okay, I guess, though the actual error message should say
something different so people realize why they get a 404. Apache gives
a 403, though IMHO that's probably a bad convention. It's only
Forbidden in Apache because indexes weren't turned on, but calling
enabling indexes a permission (that can be revoked) doesn't make any
sense. So sure, 404 with a message No index file displayed for
directories or something like that. Alternately we could display
index.html (probably based on a class method, or something passed to the
constructor, which would be a list of index filenames -- but I'm also
fine leaving it out so long as the 404 is sent in a special method that
can be overridden).
Yup. I'd prefer 404 too so we'll go with that. I'll have a look at
adding some options for directory indexes too, probably tomorrow now.
Cheers,
James

Re: new project and so many files
Hi Max, Is it really necessarily? Is it because no one yet figured out how to simplify things or this approach does provide some benefits? Well, it's a simple case of trying to make things as simple as possible but leaving everything in there that a developer is actually going to use. If the default is too much for you there is also a pylons-minimal template in development. You can try it as it stands like this: easy_install -U Pylons==dev paster create --template=pylons_minimal TestProject Perhaps there is more we could do to reduce code in the default template though. Now there is a pile code developer may never touch but the framework still expects it to work and have no control over it. E.g. any changes in framework' APIs should take this into account. That's true but because Pylons is made from middleware it is fairly easy to make API changes that don't affect existing code too much. May be it's just me, but Robaccia(*) approach feels much better: you start with a clean state and add cruft as needed. I remember Python people ditching Java frameworks for being too verbose and bragging about zero-configuration Python apps. I think you are preaching to the converted a bit here because most people on this list would agree with you! The Pylons developers have been pushing the WSGI standard and working hard to adapt existing code to work as middleware so that you can put together whatever configuration of tools you like, Robaccia being a good example. The whole point of our efforts on all the various projects we work on is to give you all this flexibility to produce your own setup *and* also to provide you with a useful default setup in Pylons that you can change if you like.

Re: Recent i18n Pylons changes
We all seem to be having different suggestions here. The issues were: 1. Whether to drop the h. prefix 2. Whether to point h._ to ugettext rather than gettext 3. How to integrate the aquarium code The current opinion seems to be edging towards: 1. keep _() in the global namespace and as h._ but point it to ugettext() 2. have the internationalization functions in the global namespace 3. leave the aqaurium code until 0.9.5 when the issue have settled down a bit My proposal is this: 1. Deprecate the use of _() and h._(). They will still work in 0.9.4 but will print a deprecation warning. In 1.0 (or maybe before) they will be removed. We'd push the use of h.gettext(), h.ugettext(), h.ngettext() and h.ungettext() and they won't be available in the global namespace, it would just clutter things and what happens if we add more functions? They are more logical in helpers. Apparently xgettext extracts the h. form fine anyway. If people really don't like this they can always import the objects from pylons.helpers manually or create new variables with which ever spelling they like! 2. 3. same as the current proposal. If anyone strongly objects to this please pipe up now with detailed reasons and we can come to a final consensus.

technique you use. Here are a load of bullet points which hopefully
clear up all the various areas you have touched on!
* Pylons doesn't have a server so you serve a Pylons app in whichever
way you prefer with whichever server
* Pylons is thread safe so you can use multi-threaded as well as
multi-process server techniques
* Pylons doesn't do any threading itself even though it can be used in a
multi-threaded environment so life is nice and simple
* One way of deploying a Pylons app is with paster serve. It is useful
for testing and (with care) can be used for production deployment.
* People who deploy with paster serve typically use Apache with
ProxyPass so that the visitors don't have to see the port and so that
they can take advantage of Apache's virtual hosts and mod_rewrite
capabilities.
* You can also use dedicated reverse proxies such as pound to load
balance to your running some paster serve apps
* If you deploy a Pylons app using paster serve it is wise to setup a
cron job to check the server is still running and restart it if
necessary. I use daemontools as described on the Pylons wiki to achieve
a similar thing.
* If you are serving a Pylons application you don't need to do anything
special with static files, Pylons itself handles them for you. Of
course, if you want Apache to handle them you can set that up too. The
easiest way is to copy them into your htdocs directory and then setup a
mod_rewrite rule so that Apache serves from the static directory where
possible and passes the request on to Pylons where it is not. I'm using
this for one of my apps, feel free to adapt it for your use:
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([-_a-zA-Z0-9/\.]+)$ /cgi-bin/dispatch.cgi/$1
Something like the above would check the filename first then internally
redirect the request to the dispatch.cgi file which could serve the
Pylons app. If you are doing this then the Pylons app will actually be
at a different location to the URL so you will need some middleware that
manually alters the environment so it thinks it is running at that
correct URL and therefore generates links that work before the rewrite.
If you do this you could also disable Pylons' static file support by
taking the static file app out of the Cascade middleware in
config/middleware.py since it won't be needed.
What I (think) I understand
---
Regardless of other intermediate things in between, you (almost)
always need to have paster serving the thing. If using Apache (at
least without mod_python), paster MUST be up and running, serving
things at some address and port.
Nope, not at all. You don't *need* to have a standalone running server,
it is just that some people find that the most simple/flexible way.
You can also deploy via CGI, FastCGI or mod_python and more which are
all described in detail on the wiki.
CGI and FastCGI methods use a dispatch.cgi or dispatch.fcgi file which
you could put in your rewrite rules for static file.
However, I am still puzzled by:
Apache is an incredibly mature technology, and having the knowledge
that when Apache is up, my site is up is quite nice. by Ben Bangert
in
http://groups.google.com/group/pylons-discuss/tree/browse_frm/thread/5de35593c4571633/a1ac095664259688?rnum=1_done=%2Fgroup%2Fpylons-discuss%2Fbrowse_frm%2Fthread%2F5de35593c4571633%2F%3F#doc_ad8deb4f3acec8e1
Is this because of mod_python? Don't they need to have paster running
underneath?
Exactly, Ben's just saying that if you deploy via Apache you pretty much
know everything will be working because Apache is good at CGI, FastCGI
etc where as if you go down the standlaone server (eg paster serve)
route you need to write some monitoring code to restart the server if it
fails. Neither should be difficult, it just depends which approach you
prefer.
As for connectors, we do not server thousands of short requests a day;
our apps. take a while to run (5 to 50 minutes) and there are rarely
more than 20 requests per appl. per day. (I.e., speed is an issues in
the number crunching code; it is inconsequential in the web-serving
part). I think plain CGI will be just fine.
Yup, that sounds fine unless your app displays thousands of static files
because with CGI to serve each static file a new Pylons app will be
loaded and unloaded. This can be avoided using the mod_rewrite approach
and having Apache serve your static files.
But I think we cannot just dump Apache because:
a) We have 7 applications, and right now only 3 or 4 of those would be
ready to run with Pylons. We need to make sure the others can still
run. I thought using Pylons via Apache would allow us a non-traumatic
transition (just re-write the relevant parts of httpd.conf when
ready).

Re: Recent i18n Pylons changes
The plan in 0.9.4 is to use h.ugettext() instead of _(). h._() will be the same as h.ugettext(). Have you seen the new docs? I think we've pretty much agreed on what is in this document now? Most of the interesting stuff is at the bottom. http://pylonshq.com/project/pylonshq/browser/Pylons/trunk/docs/internationalization.txt Any reason why any of this is a bad idea? I think discussion is still open as to whether h.ugettext() is better or just ugettext(). Cheers, James Pedro Algarvio, aka, s0undt3ch wrote: What is pylons _() attached to? ugettext?

Re: Using Durus with Pylons
Hi Mike, The globals object is *not* thread-specific! I suggest you instead create the connection in lib/base.py within the __call__. Then I'll be creating a connection for every request. Is there no better place to do it once per thread? Well, the thing is Pylons is thread-safe but doesn't actually manage any of the creating of the threads itself. Thread creation is handled by whichever server is running the Pylons app. This means if you want one connection *per thread* rather than *per request* you would probably have to set it up in the server part. For example. If you were using a paste.httpserver you could write your own thread handling that added one connection to the environ when each thread was created. You would then be able to access the connection in your Pylons app via request.environ.

Re: Error importing kid from example
Hi Sean,
I expect you are missing the TurboKid package. You can install it
manually with:
easy_install TurboKid
or, as is the case with all of the optional Pylons packages you can do:
easy_install -U Pylons[kid]
The extras are described here:
http://pylonshq.com/docs/0.9.3/install
I'll update the docs so that this is clearer.
Cheers,

Re: Internationalization - utf-16
Hi Alagu,
Presumably you have created the binary message catalog with the
following command as described in the docs:
python setup.py lang_compile
If so I have a similar problem. The tutorial works fine with ASCII
characters but not with Unicode.
I've tried re-writing Python's msgfmt.py file (which Pylons uses) to use
unicode but I'm not having much luck. It might be worth trying a more
general Python list because someone must know how to use unicode with
the built-in Python tools to generate a .mo file but I agree it isn't clear.
The solution might involve using these tools instead of msgfmt.py:
http://www.iro.umontreal.ca/contrib/po-utils/HTML/ because I have a
feeling it would all work if I could create the correct .mo file.
If you already have a .mo file from elsewhere and compiling it isn't an
issue, try upgrading to the dev version of Pylons and using h.ugettext()
instead of _(). You'll need to add:
from pylons.helpers import ugettext.
Let me know how you get on!
Cheers,
James

Re: Internationalization - utf-16
Hi Alagu, OK, I've cracked it. As I suspected there is nothing wrong with the implementation in Pylons, it is just that Python's msgfmt.py implementation to create the binary catalogs is not even slightly adequate. The solution is to use GNU gettext or a third party tool to create the catalog instead. There are some good instructions here for wordpress which could be adapted: http://codex.wordpress.org/Translating_WordPress I used poEdit from: http://www.poedit.org/ and did the following: Install it Create a new catalog A dialog pops up: Project Info tab: Fill in *all* the fields Paths tab:Enter the path of the root of your project eg translation_demo Keyword tab: Add the keywords ugettext and gettext You can then click OK, it will find all the strings and then you can enter your translations in whatever charset you chose at in the project info tab. You then save the catalog and rename the .mo file produced to translate_demo.mo and put it in the translate_demo/i18n/es/LC_MESSAGES directory or whatever is appropriate for your translation. I've tested it on Windows with your Arabic phrase and it works fine. Let me know if you have any problems.

Re: Pylons on Ubuntu (with Python 2.5)
OK, this is a bit desperate but download cheetah 1.0, extract it, then disable the _namemapper extension by commenting out lines 24-29 of SetupConfig.py then run python2.5 setup.py sdist to create a source distribution. The file will be in the dist sub directory and then you can install your new egg: easy_install -U Cheetah-1.0.egg If I'm not mistaken this should install Cheetah without doing the compilation and I think it should work without it, just a little slower.
