I'd love to move ot Mako, but refactoring and translating 6k lines of messy templates isn't really an option. I looked over pylons.templating and I'm kinda over my head in understanding what I need to do to have a render_myghty. Anyone else using Myghty with 0.10?

Hi,
I am trying to figure out what would be the best way to write batch
(command line) tools in pylons.
Basically, what I need is a replica of the configuration that my live
site uses, but instead of controllers getting the requests, its a
command line tool. Everything else (globals, caching, database, etc)
should be the same.
I looked at the command line utilities section in pylons documentation,
but I can't seem to figure out how to everything loaded properly.
loadapp() gives me an instance of the app that can be passed on to a
wsgi server, but that's not what I was looking for.
Another option will be to just run a paster serve and write a
controller, but that doesn't seem to be the right way to do things :(.
What's the best approach to do this?
You can add an entry point to add paster commands that will work with
your app loaded. This requires a bit of hackery, but is pretty
simple.
First, I make a directory project/project/commands.
Second, add an entry point in setup.py:
entry_points=
[paste.app_factory]
main = project.config.middleware:make_app
[paste.app_install]
main = pylons.util:PylonsInstaller
[paste.paster_command]
MyIsh= project.commands.MyIsh:MyIsh
,
Third, I follow http://pythonpaste.org/script/developer.html to make
a command. It basically has to be kinda like this:
from paste.script.command import Command
from paste.deploy import appconfig
from pylons import config
from project.config.environment import load_environment
class MyIsh(Command):
def command(self):
conf = appconfig('config:%s' % yourconfigfile)
load_engironment(conf.global_conf, conf.local_conf)
'''do your stuff'''
Fourth, I run it like paster MyIsh or paster --plugin=project MyIsh

Re: writing to g/app_globals -- is it safe for caching info after startup ?

I keep a lot of stuff in app globals that is set on startup and never changed. If you need a cache use something like memcached - that works very well, and is easy to use. I can recommend doing this through beaker as it has nice features such as dog-pile-effect prevention for when your cache expires. If you cannot use memcached you can use other backends interchangably with beaker. My objects aren't picklable or hashable - they have live TCP sessions. This means they can't be stored in beaker or memcached. I have to have sockets hang around in some globally accessible memory. Not being threadsafe isn't the end of the world for me. I've just hacked up a basic per-entry locking dictionary for my objects and it seems to behave nicely in app_globals. I'm concerned about bugs throwing exceptions in critical sections. In that case, I'll probably leak the mutex hold, which means subsequent actions will fail.

What is the best way to user CAS authentication with Pylon ?
I tried to use pycas (http://www.ja-sig.org/wiki/display/CASC/Pycas)
putting the four lines in one of my controllers but this led to server
errors.
I never found an easy to use, ready to go Python module. It was
pretty easy to roll my own - CAS is pretty trivial. I have an
authentication controller that users are redirected to if they do not
have a properly authenticated session. The CAS interaction looks
like:
-
if not request.params.has_key(ticket):
url = %s/login?service=%s % (config.get('casurl'),
urllib.quote(config.get('appurl')))
return redirect(url, code=307)
else:
url = %s/validate?service=%sticket=%s % (config.get('casurl'),
urllib.quote(config.get('appurl')), request.params[ticket])
(response, username) = urllib.urlopen(url).readlines()
if response.strip() == no:
url = %s/login?service=%s % (config.get('casurl'),
urllib.quote(config.get('appurl')))
return redirect(url, code=307)
-
In my config, the variables look like this:
casurl = https://cas-host/
appurl = https://myapp/auth/
If the user passes CAS and falls through the above code, my app sets
them up a session with the appropriate authorization details.
On the official CAS server, you'll need to do a bit more elaborate
parsing of the response - the above works with RubyCAS, which
implements different responses.
Authorization is then done with the username against an LDAP
directory. CAS is purely for authentication.

Re: Authentication Authorization for multiple apps?
On Wed, Dec 16, 2009 at 08:13:39AM -0800, flzz wrote: Greetings all, my company is currently in the process of migrating to python + pylons as our development platform of choice. We currently have a good bit of traffic to support and to help ease maintenance and operation overheads we will be creating multiple pylons applications to service certain aspects of our application on the whole. To the question. Is it possible to have a single Authentication and Authorization model (repoze.who repoze.what) that is shared among multiple pylons applications? We currently utilize the debian packaging system (Ubuntu) to handle software deployment, so the approach I can see us taking is to abstract out the AA portion of the system into its own package (deb/egg). Then from that point we will create our own pylons template that includes the use of this system. Am I off base with this approach at all? it seems uniformity of WSGI and the modular nature of pylons should make this doable. What I've done is integrate CAS into my pylons app as a replacement for any kind of local authentication. CAS handles user sign in, and supposing that you accomodate it well into your applications, will automatically grant authenticated access to users across applications. This gives nice single sign on for many apps, including diverse application servers and stacks. This leaves authorization and session setup issues to the application. Having shared sessions sounds elegant, but difficult.

Form fields and the back button
Hi everyone, Back in the days of Pylons 0.9.5, if you incorrectly filled out a form in my app, submitted it, got an error, and then pressed the browser back button, you would always get a copy of the form pre-filled with the values that were there when it was submitted. At some point since then, something changed. I don't know if it's Pylons, Firefox, or Apache. Now, there's two cases: 1) When my app runs under paster, it always behaves as above. So in my development environment, I can hit back, correct one field in a form, and resubmit. Great! 2) When my app runs in production, under Apache+fcgi, pressing back always gives a blank form. A few of the guys in the office have spent a bit looking at this (they're the ones mostly affected, heh). We've looked through a few things: The HTTP headers from Paster and Apache are identical, the HTTP headers sent from the client are identical. The behavior is consistent across multiple browsers and platforms (IE and Firefox on Windows, Firefox on Ubuntu/Debian/Fedora). Anyone have any ideas on what is causing this or what I can do to make it not clear the form fields? -- Ross Vandegrift r...@kallisti.us If the fight gets hot, the songs get hotter.

Generic routes for API functions
Hi everyone,
I'm adding API functionality to an exiting app whose controller
actions aren't close to being in shape for direct exposure. This
pretty much precludes me from turning them into REST controllers and
accomplishing this task that way.
So I've created a new api controller that will house the actions for
programmatic access. This has an unfortunate side effect of making my
routing kind of difficult.
For example, suppose I have model objects X and Y and the following API:
class ApiController(BaseController):
@jsonify
def getXbyid(self, id):
q = meta.session.query(model.X)
result = q.get(id)
return {result: result.__json__()}
@jsonify
def getXbyacct(self, acct):
q = meta.session.query(model.X)
result = q.filter_by(acct=acct).one()
return {result: result.__json__()}
@jsonify
def getYbyname(self, name):
q = meta.session.query(model.Y)
result = q.filter_by(name=name).one()
return {result: result.__json__()}
How can I effectively map these actions without listing each action in
my routes? The best I have come up with is to include a route for
each parameter name I use:
map.connect(/api/{action}/{id:[0-9]+}, controller=api)
map.connect(/api/{action}/{acct:[0-9]+}, controller=api)
map.connect(/api/{action}/{name:[a-zA-Z0-9+}, controller=api)

Also looks like a changed was made in the latest release of google protocol buffers (which I use for RPC) that changed the way data gets loaded from the wire. Whereas the pyhon library used to only use Unicode types for representing data that required it, it seems this was a bug. As a result, I think all kinds of weird stuff was being injected.

Disabling unicode doesn't always disable unicode in 0.9.7
Hi everyone,
One of my app's primary functions is to speak SNMP to routers and
switches. This completely precludes the use of any Unicode - something
that's getting very frustrating in Python (not just Pylons!)
I've got:
config['pylons.request_options']['charset'] = None
config['pylons.response_options']['charset'] = 'iso-8859-1'
in my config/environment.py.
But I still have request.params being passed up the stack with
everything as Unicode. Here's one example:
UnicodeMultiDict([('location', u'2'), ('domain', u'2'), ('hostcount',
u'6'), ('customer', u'a'), ('type', u'2'), ('description', u'a'),
('ttype', u'srt'), ('nexthop', u'172.16.0.4'), ('vlanmethod',
u'auto'), ('vlan', u'0'), ('interface', u'Vlan99')])
I didn't see this behavior until 0.9.7. I've also tried setting
config['pylons.request_options']['charset'] = US-ASCII, but the data
comes through the same.
According to [1], the config/environment.py value is overridden by the
browser's Content-Type header. From wireshark, I can see that my
browser is sending Content-Type: application/x-www-form-urlencoded -
I don't see any mention of UTF-8 encoding there, but I don't totally
know what that means.
What's more perplexing is that despite the environment.py settings to
use ISO-8859-1, and my HTML settings that are shipping ISO-8859-1,
PasteServer's HTTP headers still say Content-Type: text/html;
charset=UTF-8!
What do I have to do to really prevent Unicode from showing up in my
variables? Hopefully, I don't have to wrap every string in my app
with str()...

Mako template examples
Hi everyone, I inherited a horrible mess of Myghty templates, most of which are a cut-and-paste disaster. I've decided to undertake refactoring them and converting to Mako. The Mako docs are great and explain all kinds of wonderful things I could do. But never having had a maintainable template system for an app that displays lots of tabular data, I don't really know where I want to go. I downloaded the pydotorg examples from the Mako site, but their system is wy more complicated than I need or want [1]. Anyone know of a free software app that uses Mako, in a pretty direct fashion, and has a nice template structure I could pick apart to learn from? Thanks, Ross [1] Though the approach of using RFC-822 headers in text files that get translated into HTML is probably the most brilliant idea I've ever seen in HTML construction. If that were refactored into a standalone library, I'd use it. It's beautiful, though complicated. -- Ross Vandegrift r...@kallisti.us If the fight gets hot, the songs get hotter.

Sudden setuptools conflicts
Hey everyone, Recently, I've been working on an app that has branches using Pylons 0.9.6 and 0.9.7. Previously, to switch between them, I would do python setup.py develop and the requirements for my current version would be activated, overwriting the choices of the previous installation. Sometime in the recent past, setuptools stopped doing this. Now, when there's a conflicting version it bails out and warns me. I have to resolve the situation manually.

I'm trying encapulate all data stuff in the model. For example, I
have a Book object so it would have methods like get, get_all, recent,

/models/book.py:
class Book(object):
def get_all(self):
query = meta.Session.query(Book).filter_by(user_id=1)
return query.all()
def save(self):
meta.Session.save_or_update(self)
meta.Session.commit()
[snip]
I can see that maybe the model can't save itself and instead the
session should be saving it. But how do I go about doing that using
this modular structure?
SA treats your model object (ie, the class that encapsulates the logic
of your application) separately from the Session (ie, the class that
encapsulates information on how to save and restore persistent data
for object instances).
I think of it like this: a Book object should keep properties about
itself - the title, author, publication data, editon, etc. But a Book
is not the kind of object that saves and loads things to a database. [1]
The SA Session is the kind of object that saves and loads things from
a database. You setup mappers so that SA knows what to save. I would
implement your object like this:
class Book(object):
def __init__(self, title, author):
self.title = title
self.author = author
self.bookmark = None
def bookmark(self, pageno):
self.bookmark = pageno
There's no database code in there, just Book code. Here's the
database table information:
import sqlalchemy as sa
book_table = sa.Table(Column('id', sa.Integer, primary_key=True),
Column('title', sa.Unicode()),
Column('author', sa.Unicode()))
Finally, you need an ORM mapper to link the two up:
import sqlalchemy.orm as orm
book_mapper = orm.mapper(Book, book_table)
Then, in the pylons controller actions, I would do things like this:
class SomeController(BaseController):
def action(self):
q = meta.Session.query(model.Book)
c.paine = q.filter_by(author=Thomas Paine)
c.jefferson = q.filter_by(author=Thomas Jefferson)
return render(/showbooks.mako)
(where showbook.mako iterates over those books and displays some
interesting information about what's in the database).
[1] At least, I have never seen such a book :)

I'd also have to question your use of always in the above sentence. I strongly suspect aren't speaking from experience here, rather just hearsay. Hmmm, now that you mention it, I think all of those deployments may have been lighttpd. I had to hear a lot of the fallout - lighttpd was being used to generate tokens on servers that would be used for instantiating authentication credentials in a single sign-on server for admins. So there was much gnashing of teeth whenever this would crap out. I was fortunate enough to not have this be my baby, and mostly didn't have to deal with it. But I probably shouldn't continue to take that experience as indicitive of everything that's not Apache. And it's poorly understood by just as many, if not more. I first switched from Apache not due to scalability concerns (like you, I've not encountered them), but because I find Apache's configuration to be overwhelming and convoluted. Really? I can see it being overwhelming, but it seems very understandable to me. Paired with their documentation, I don't think I've ever had a real problem getting Apache to do something I knew it could. Well, unless you count kinda crazy, obscure mod_rewrite stuff - but of course that's a black art just because the rabbit hole goes as deep as you care to follow :). The fact that you need an army of support reps isn't really advancing your argument ;-) Heh, well, for every change needed to Apache, there's 1000 people that need help configuring their POP3 client. Apache is hardly the reason the reason there's an army :). This makes Apache best for... medium-sized sites that don't care about resource utilization? This is a ridiculous claim, so I'll assert instead that Apache is best if you need a *specialized* service, such as mod_svn or mod_jakarta. I don't think that's such a ridiciulous claim! Consider the application server that hosts the apps that I write for my company's internal use. It hosts four or six Pylons applications and one Rails app. One of these apps handles around 1000 uses a day, one around 100, one around 10. The Rails app is an AJAX form that just pushes collected data to the browser, so is usually busy despite only having an average of 1 user a day. The server these apps are housed on is gratuitously overpowered. Apache's flexability makes this use-case trivial. Maybe this deployment pattern is uncommon? Apache proponents will point out the wealth of modules as evidence that Apache is the best for general purpose web serving. But being best at fronting *particular* applications doesn't make it best *in general*. So it's not Nginx that's specialized for a particular workload, it's Apache that's specialized. Eh, I wouldn't make that claim about Apache modules. Many of them are irrelevant to me, some seem downright pointless. Nginx is like a finely-balanced chef's knife: suitable for a variety of tasks, large and small, as long as they all involve slicing. Apache, on the other hand, is the swiss-army knife of webservers: bulky, full of odd specialty tools, and on occasion, marginally useful as a knife. In either case, apparently they both make for a funny lump in some people's pockets ;-) I wouldn't want the lump of a chef's knife anywhere near my pocket, lest I be bleeding out all over the floor! Anyway, I think we've gone way OT for long enough. We can continue offlist if you like. I'm more or less done - I think you've convinced me that Nginx is probably worth another look at some point.

Sites that are amongst the largest on the internet fall into a corner case in my mind. As Mike pointed out, sites have an unrealistic expectation of traffic. I've been involved in the average cases. My claims come from years in the service provider industry, watching various deployments. I've been an Apache fan for a long time, and have seen and deployed hundreds of servers, serving thousands of sites on Apache. None are youtube.com - and I agree that this is an important point. Comparing my Apache deployments with deployments of other servers, year after year, Apache won hands down: 1) Users of other HTTP servers are always fiddling with them, restarting after crashes. This may be due to misuse, non-optimal config - I'm not sure. But I've never had stability issues like this with Apache. 2) Apache is well-understood by many more folks. There's an army of support reps downstairs that are compentent, if not experts, at maintaining and troubleshooting it. The other servers come across as mysteries (despite often being highly trivial), and end up escalated instead of fixed. 3) Documentation for Apache is through, searchable, and understandable. It's full of examples, is available for multiple versions of httpd. I have seen the Apache documentation turn motivated people from competent levels to expert just by googling for it. I'm not saying that other servers don't have decent docs - but Apache's are amongst the best docs for any software I have ever read, and I have seen them function in production for years. I'd qualify this paragraph as some of Apache's strengths are, rather than a blanket it's better. For some people, in some settings, it is better. For others it isn't. If you need high scalability, it isn't the best. If you need a small memory footprint it's not the best. If you prefer a sane configuration syntax it isn't the best. If you need all three then it's arguably amongst the worst. Yea, you're right - I'm tacitly assuming that we're talking about the average cases. Other http servers definitely excel at things, especially for workloads they have been specially designed. But for every youtube there's tens of thousands of websites with more average traffic and control needs. -- Ross Vandegrift [EMAIL PROTECTED] The good Christian should beware of mathematicians, and all those who make empty prophecies.

Re: Auth and Auth
On Fri, Mar 28, 2008 at 10:19:35PM -0700, Mike Orr wrote: Their argument seems to be not that it doesn't work (the previous bugs have been fixed), but that you can write your own authentication in the time it takes to learn it. I haven't used AuthKit in a program so I can't say definitively one way or the other. As for the number of AuthKit discontents, it's impossible to say whether they're a substantial percentage of the Pylons userbase or a small number of loud activists. I recently attempted to upgrade an existing application from an ad-hoc authentication and authorization framework to AuthKit. In the end, I decided my ad-hoc method was better. I'm not an AuthKit expert, though I did give it a good try. Here were my reasons: 1) Bad documentation is worse than no documentation. Much of the AuthKit documentation is out of date enough that it leads you down the wrong path. The API reference are more useful than the examples, but they are very difficult to follow, without being familiar with the guts of AuthKit. 2) The only way I could determine to get style control over the login screen (the forward method), was very complicated to implement. As Mike said, complicated enough that I could write my own middleware to do it in a similar amount of time. 3) What's worse is that I could never get forward authentication working. The nice decorator syntax and uniform authorization API was what I wanted, but I couldn't get to that point. AuthKit is probably most helpful if you have a complex permissions scheme and use the built-in plugins. It's less helpful if you use the forward feature to call back into the application for the login form. In that case you're doing most of the work yourself anyway and merely shoehorning it into AuthKit's API. I agree with you 100% here, but I'll take it a step further. Authkit's API is what's great about it. But who wants to choose the barebones login screen it provides or an HTTP authentication window? Is that really a common use case? AuthKit's ability to express complex permissions for authorization is really awesome, and it's where I see a lot of the value - the API is very well considered. But getting an app with a custom login screen converted over to it was enormously difficult. In that case you have to ask whether five lines of AuthKit API calls is really better than five lines of homegrown code. Probably not, and I think Gardner would agree here. For complex permissions, this is a gross underestimate. My app (though it could use some refactoring at this point) has hundreds of lines for permissions between different roles and groups of users. It includes LDAP interaction to get that data. It also has really ugly hooks into the controllers to verify a user. The object model of roles in AuthKit is the value - it's a lot like RADIUS/TACACS+ if you're familiar with the router kind of AAA model. I found that it wasn't trivially easy to reproduce that. I see that AuthKit does both, but I'm not sure how well it cascades from one to the other, or whether it will accept my existing Users table. It does? I couldn't find any information on linking AuthKit with LDAP (without writing my own objects to do it). And most of the information I could find on using a database table seemed to be about people unable to get it working. I had good luck with statically configured users, but this doesn't scale. In summary - it might just be a documentation issue. I really like AuthKit's ideas. They seem very correct to me. It's just too difficult to integrate into an app. -- Ross Vandegrift [EMAIL PROTECTED] The good Christian should beware of mathematicians, and all those who make empty prophecies.
