decorator as a normal function is funky.

ret = jsonify(lambda: s)()

surprised to find out that stylesheet_link_tag was gone. It's been renamed
stylesheet_link.

imports),
I had to manually change how I imported render to

function. I'm guessing this isn't a big deal.
* I had code that was setting response.status_code. It's documented here
http://wiki.pylonshq.com/pages/viewpage.action?pageId=11174779 that you
should use status_int. However, I didn't catch that and there was no
deprecation warning. Hence, my code failed silently, or rather it didn't
fail at all. It returned a 200 when I was trying to return a 400. A
deprecation warning would have been nice.
* Once I got response.status_code working, it started shoving my HTML
response into the middle of a big error template instead of just serving
what I had. This totally messed with my Web service which counts on
the sparse HTML error messages I provide. I hacked around the problem.
In my action, I wrote:
request.environ['error_response_is_intentional'] = True
In error.py's document method, I wrote:
resp = request.environ['pylons.original_response']
if request.environ.get('error_response_is_intentional', False):

message=content)

This is definitely a hack. I'm not even sure why this behavior changed.
If I set request.status_code, and I set the HTML containing the error
message, it should just leave it alone.
By the way, why does the code use
request.environ.get('pylons.original_response') when it soon does
resp.body? Why not do a normal dict lookup (i.e. [])? If you don't have
that key, you'll get a None, and resp.body will crash anyway.
Ok, I hope that was helpful. If you want bugs for any of these, I'm
happy to submit them.
Best Regards,
-jj
This thread kind of died. I think that some of the above should
result in changes to the upgrading notes, and I think one or two of
them should probably result in code changes. Should I submit patches,
bugs, etc.?

One of the default middlewares is doing this--StatusCodeRedirect. I
completely removed this from the Pylons project I'm using for web
services.
In another project, I have this in certain controllers:
request.environ['pylons.status_code_redirect'] = True
I found that by reading the source. If I understand it correctly, it
disables StatusCodeRedirect for a given request. (It seems to work,
but the semantics are confusing.)
Yep, that worked like a charm, thanks!
Since this is a change in behavior and it requires a change in code to
get the old behavior back, it probably makes sense to call this out in
the upgrading docs.
Thanks Again,

One more:
* I don't use the Pylons way of running nose. I test my Pylons app as just
one of the packages in my project. Hence, I have a Makefile
with nosetests --with-doctest $(OUR_PACKAGES). I had to add
--with-pylons mywebapp/test.ini. I kept getting
ERROR: Failure: KeyError ('__file__') when trying to run my
tests, and a bunch
of my other tests failed because they couldn't get an expected value from the
.ini file.
This is hinted at in
http://pylonshq.com/articles/archives/2009/2/pylons_097_released,
but perhaps needs to be called out more explicitly for those of us who run
nosetests manually without going through setuptools, etc.
Thanks!

You're trying to use the session from outside the context of a Web request. At that point in the code, in a sense, Pylons isn't even fired up. Here are two approaches that might work: * Use one action to put something into the session and then another to make use of the session. It's a work flow. * If I remember correctly, there's a way to shove stuff into the environ that will be passed to the request. Shove in a callback named setup_session_for_tests that gets called by the parent class of the controller. You can also mess around with the environ after the request.

prints c.title.
If your title string is foo+bar, mako renders the string foo+bar,
whereas if your title string is foo%20bar, it renders foo bar.
Generally, this isn't much of an issue, as one can make URLs that have
%20 instead of +, however the redirect_to() function in pylons changes
spaces to + and not %20.
So my question is, is there a way to change how redirect_to encodes
strings? I've tried changing spaces to %20 prior to passing it to
redirect_to, but all that happens is that the % sign gets encoded
itself and %20 shows up as part of the title.

Bob talks about security a bit on his blog post: http://bob.pythonmac.org/archives/2005/12/05/remote-json-jsonp/. Let's say I have a JSON method that returns your list of friends. That's private, and the method is restricted based on authentication. But any random website could include this: script src=http://somesocialnetwork.org/api/friends?jsonp=readFriends;/script and then it would be able to read your private list of friends if you had logged into somesocialnetwork.org. Simply requiring people to explicitly turn on jsonp support, with a warning that only public data should be exposed that way, would address that issue. Good point. So you're saying that if you don't use jsonp, then when the attacker causes the victim to view a script tag that pulls stuff down via JSON, since there's no function to receive the JSON, it gets pulled down, but immediately disappears, right? What a strange defense mechanism. XSRF is a pain, eh? I'm okay with needing to turn on jsonp support. If there were a jsonp flag for the jsonify decorator, then you could enable it in as few places as possible.

I am trying to figure out what the best practices for dealing with
static resources such as CSS, Javascript and images are. With a
default pylons setup every request goes through two StaticURLParser
instances and files returned by them do not get any caching headers.
This is very practical for development but not ideal for a deployment
For a deployment it would be nice to be able to serve static resources
from apache or nginx.
How do others do that? Do you use url_for to generate a URL for those
static resources and have that return a non-paster/pylons URL for
deployment environments and use the StaticURLParsers when running in
in development mode? If so, how did you set that up?
I usually just setup Nginx to handle whatever location my static content
is at. It doesn't matter if Routes is setup to handle that location as
the request never reaches Pylons.
Here's an example:
server {
server_name *.domain.com;
listen 1.2.3.4:80;
location /public/ {
root/var/www/myapp;
expires 30d;
}
location / {
proxy_pass http://127.0.0.1:8000$request_uri;
include/etc/nginx/proxy.conf; # common settings for proxying
}
}
In this case, any request for, say /public/css/style.css would map to
/var/www/myapp/public/css/style.css.
Regards,
Cliff
I let Nginx handle the URL if such a file exists. Otherwise, I let
Pylons have a shot at it:
...
server {
listen 80;
server_name localhost;
location / {
# Let Nginx handle static content, but proxy to paster for all the
# dynamic content.
root/.../wwwaiter/wwwaiter/public;
if (!-e $request_filename) {
proxy_pass http://127.0.0.1:5000;
}
}
That way I don't have to include public in my URLs ;-)
(Of course, including public in the URL would probably make life
easier if I needed to move to something more complicated like a CDN.)

Re: Difference between controllers and views?
Yes. You could hack around that, but it'd probably be painful. What I'm saying is that: a) Using classes is a good idea. b) Pylons doesn't force you to code a certain way within those classes. You can move as much or as little as you want into the models or other libraries.

What's the gain in this controller approach, if any? :) Thanks... I differ a bit from the opinions above. I like to think of a web request as asking show me something. Therefore, IMO, it makes sense to map a web request to a view. The view (a Python class) then knows how to use actions (a Python class) to do something, the actions know how to use the model to get work done. The view then renders a response in an appropriate format (HTML, JSON, etc.) using any helpers necessary (i.e. templates). The view does not have to render using a template though. I had a diagram of this at one point, but can't get the darn thing to open right now. If anyone is interested in seeing a diagram let me know and I will try to get it working and post one. What you are describing is closer to the Rails philosophy. They're big on pushing stuff into models, even validation. I've done it that way, and that works too. I think of it like a pie. You can slice the pie in many ways. Slice it however you like. That's one thing I like about Pylons. It does make you use a class with methods, but it doesn't force you too much beyond that. If you want to do something strange like put all your logic in models and then use string interpolation within your controllers you can. Whatever floats your boat ;) Happy Hacking! -jj -- I, for one, welcome our new Facebook overlords!http://jjinux.blogspot.com/- -- I, for one, welcome our new Facebook overlords! http://jjinux.blogspot.com/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: Bulk inserts
Beware of multiple threads and/or processes writing to the file at the same time. It may make sense to use a mutex. I agree with the earlier recommendations to use mysql load data in file. It really is a lot faster. You can completely remove Python from the picture when importing the file. Here's an example: mysqlimport \ --user=user \ --password=password \ --columns=id,name \ --compress \ --fields-optionally-enclosed-by='' \ --fields-terminated-by='\t' \ --lines-terminated-by='\n' \ --local \ --lock-tables \ --replace \ --verbose \ mydatabase mylocalfile.tsv To write that tsv file, I used the csv module with: DEFAULT_KARGS = dict(dialect='excel-tab', lineterminator='\n') def create_default_reader(iterable): Return a csv.reader with our default options. return csv.reader(iterable, **DEFAULT_KARGS) def create_default_writer(iterable): Return a csv.writer with our default options. return csv.writer(iterable, **DEFAULT_KARGS) There's one more thing to keep in mind. If you do a load data from file using Python, make sure you pass local_infile=True to MySQLdb's connect function.

What's the gain in this controller approach, if any? :) Terminology really. Note that webapps in general are only vaguely mapped to the entire MVC concept in that you have a model representing domain logic (generally with a database), a controller that gets the request and decides how to respond, and a view (template) which the controller uses to create the response with the data (Model). So Django is more-or-less MVC, they just call it MTV (Model-Template-View), and their 'View' is doing the logic with the request, fetching data from the Model, and using a template (aka, view), to return a response. By any definition of MVC I've seen, Django is without a doubt MVC as well: http://en.wikipedia.org/wiki/Model-view-controller They've provided a reason for why they choose to call it MTV on their FAQ page, which differs from every other web frameworks rather unanimous interpretation of it, and so far has led to more than a little confusion when I've seen Django users using other MVC frameworks and frequently asking about 'views' when people understand that to be 'controllers'. Regarding the use of a class vs a function for the controller, there are some advantages with the class. You can easily have stuff done before any of the methods are called for example, and you can set things on the class object and have helper function utilized that have access to them on 'self' as well. Also, you can develop mix-in style classes, to easily add generic methods to various controllers merely by changing the inheritance. MVC is a cargo cult ;) http://jjinux.blogspot.com/2005/04/mvc-cargo-cult.html I agree with Ben. Having classes with methods has all sorts of OO benefits. Consider, you can implement __getattr__ and do all sorts of cool tricks. It's also nice to share a bunch of code and data via self. If you don't use classes, you're forced to do everything with function decorators. -jj -- I, for one, welcome our new Facebook overlords! http://jjinux.blogspot.com/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Say the Paster process is doing some I/O (SQL query through sqlalchemy), would that process block and would other requests wait, or would they get serviced? Hi Sam, According tohttp://wiki.pylonshq.com/display/pylonscookbook/Pylons+Execution+Anal... paster is multithreaded. It should be easy to test. Hit a controller action that sleeps for 10 seconds and see if you can still make requests to other actions. I actually need to test for myself as soon as I get to work. As for why you get failed requests, I don't know. class FooController(BaseController): def bla(self): return 'Hello World! %s' % time.time() def slow_bla(self): time.sleep(10) return 'Hello slow World!' With something like that, manual testing works just fine (ie: I'm able to hit the action bla as many times as I want while the action slow_bla is still serving). When testing with ab though, I do get failed requests, but I actually get even more failed requests with Apache/mod_wsgi. What options are you using to 'ab'? The 'ab' program can give a perception of errors, normally manifesting as lots of exceptions on server side in log file, if you use concurrent requests. This occurs because it only stops when it receives responses for the number of requests you tell it to make. With a request handler that takes a long time, because of a sleep() call, the 'ab' program can actually issue more requests than you tell it to. When it does receive responses for the number you told it, it will simply shutdown the connections for all the additional requests it made which it hasn't yet received a response. The result of this is that on the server side it will see a bunch of closed connections causing failures to be able to write the responses for the additional requests. The end result is that one thinks that the hosting mechanism is having problems, when in fact it is due to how the 'ab' program works. That's akin to the user pressing the Stop button in the browser. I get a connection reset line for that in my Quixote apps but not in my Pylons app. I assumed Pylons just ignored the exceptions because it's not really an error if the client goes away. But in any case, I don't get socket errors in my Pylons error log, and I can't assume that's because nobody ever presses Stop. So if Alex is getting such errors, the question is why the difference in behavior? For mod_wsgi at least, it is a bit pendantic and errs on the side of logging such events on the basis that in some cases it may actually be because of problems in code and/or the user may want to know. There is an issue for mod_wsgi related to this where speculated that it could be made less noisy on such issues where it makes sense: http://code.google.com/p/modwsgi/issues/detail?id=29 and/or whether the messages are displayed dependent on logging levels. At the time it was low priority and haven't since had a chance to get around to looking at it more closely, but will be doing so in next round of code changes. From a couple years of experience, here's the code that ended up in Aquarium's Web server, glass. You're welcome to take it for Pylons or Paster if you find it useful. def is_disconnect_error(self, e): Is ``e`` an error like ``errno.EPIPE`` or ``errno.ECONNRESET``? Various types of sockets might represent disconnect errors differently. Hopefully, one of the ways I've coded will apply. if (isinstance(e, socket.error) or isinstance(e, exceptions.OSError) or isinstance(e, exceptions.IOError)): errnos = [errno.EPIPE, errno.ECONNRESET] if len(e.args) and e.args[0] in errnos: return True if getattr(e, errno, None) in errnos: return True return False Best Regards, -jj -- I, for one, welcome our new Facebook overlords! http://jjinux.blogspot.com/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

On Fri, May 30, 2008 at 5:12 AM, Alex Marandon [EMAIL PROTECTED] wrote: 2008/5/30 Graham Dumpleton [EMAIL PROTECTED]: class FooController(BaseController): def bla(self): return 'Hello World! %s' % time.time() def slow_bla(self): time.sleep(10) return 'Hello slow World!' With something like that, manual testing works just fine (ie: I'm able to hit the action bla as many times as I want while the action slow_bla is still serving). When testing with ab though, I do get failed requests, but I actually get even more failed requests with Apache/mod_wsgi. What options are you using to 'ab'? -n 1000 -c 3 The 'ab' program can give a perception of errors, normally manifesting as lots of exceptions on server side in log file, if you use concurrent requests. This occurs because it only stops when it receives responses for the number of requests you tell it to make. With a request handler that takes a long time, because of a sleep() call, the 'ab' program can actually issue more requests than you tell it to. When it does receive responses for the number you told it, it will simply shutdown the connections for all the additional requests it made which it hasn't yet received a response. The result of this is that on the server side it will see a bunch of closed connections causing failures to be able to write the responses for the additional requests. Note that I didn't test against the action that does a sleep. I'm a bit confused by your explanation. Does it mean that the errors should show up in the logs on the server side? I was only looking at ab's output. I have a few comments: * First of all, within the last few weeks, there was a massive thread about the best way to deploy Pylons applications. That's a must read. Personally, I opted for Nginx with Paster, but YMMV. My situation is a bit strange anyway. * There were a couple good points made above about whether to run one or multiple copies of Paster. It's true that this is one place where Pylons/Python is very different from Rails/Ruby, as mentioned above. If you're mostly blocking on IO, then multiple copies won't help much since multithreaded programs are fine in Python if they're IO constrained. If you're blocking on CPU, then multiple copies of Paster running are a really good idea, otherwise the GIL will get in the way of your making use of multiple cores. * Socket connections have a setting for how many requests are allowed to wait in the queue before being accepted. I don't know what the setting for Paster is or how to change it. I do know that I've used ab before, and it hit this limit. This is the likely cause of Connection Denied errors. * ab is a bit simple minded to begin with. I've told it to use 100 concurrent requests (which I saw that you didn't do), and it saw all sorts of failed connections. Of course, getting 100 *concurrent* requests isn't all that common for most production servers. If you were able to handle 100 concurrent requests, and process each in 0.1 seconds, that would lead to 86,400,000 requests a day! Yeah, I wish ;) JMeter is nice in that it allows you to script how a real user would behave. I've also heard that HTTP Perf is nice, but I haven't tried it. * I saw a great talk on Google App Engine yesterday where one of the speakers was criticizing naive load testing. He said that if you slam a Google App Engine app, it doesn't have enough time to warm up a bunch of Python interpreters to serve your app. It'll perform poorly. However, if you test a more sustained, realistic, and organic growth rate, the infrastructure organically grows to scale. It was interesting.

The WSGI from the ground up mentality seems to be a real plus. However, I have run across a show stopper for me with Pylons unless I have missed something in the documentation. Does Pylons support some kind of module/plugin architecture that will allow me to develop plug- in functionality across Pylons projects? What would be called in Django an app. For example, I would like to have a news, blog, and calendar module that I can plug into different applications. The goal is to have everything for the module contained in one subdirectory including any configuration, routing, templates, controllers, model, etc. So, something like this: /modules/news/... /modules/calendar/... /modules/blog/... I'm sure others will say something different, but my approach has always been to simply run multiple apps on separate subdomains. Subdomains are free ;) In the past, I had login.foxmarks.com, my.foxmarks.com, and www.foxmarks.com. Each of the apps were completely separate, but I used Genshi to create a common look and feel. -jj -- I, for one, welcome our new Facebook overlords! http://jjinux.blogspot.com/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: accessing request handler from BaseController

Hello,
I am not very happy with the default validation scheme suggested by Pylons
and trying to design my own.
The idea is to let the code handle main code path (data is valid) and
handle validation error separatedly. I want to be able to set
validation_handler which is then invoked by BaseController when validation
fails.
E.g.
class SomeController(BaseController)
def index(self):
code = get_request_param('code', validator=...)
# do something with validated parameter code
index.validation_handler = lambda errors: Response('Oops!')
class BaseController(WSGIController):
def __call__(self, environ, start_response):
# ...
try:
return WSGIController.__call__(self, environ, start_response)
except ValidationError, e:
validation_handler = getattr(XXX, 'validation_handler', None)
or default_validation_handler
return validation_handler(e)
I struggle to find the XXX object I can query to access the
validation_handler (such as the one defined for index()).
Any ideas?
Somewhere in the environ, there's the Routes stuff. You can use that
to figure out which action was executed. I usually just print out the
environ and start poking around. Once you know what action was
executed, get the actual method via getattr(self, action_name).
From there, you can do getattr(action_method, 'validation_handler',
None). Make sense?

Other configs I've seen require downloading some modpython_wsgi.py file and then hacking it a bit, but there seem to be multiple different versions of this, and even more different Apache config styles to use it. I've tried some and they fail, then indicate a .core file might have been created but it isn't so I can't diagnose it that way. So what's the current recommended way to front Pylons with mod_apache? Or if there are better ways to run Pylons apps behind Apache, what are your recommendations currently? The current favorite way to run Pylons apps behind Apache is to proxy them and use Paster. It's exactly the sort of problems that you ran into that make some of us wary of mod_python. (Hi, Alec!)

Re: use of globals, threadless, and requests
On 5/29/07, alecf [EMAIL PROTECTED] wrote: I'm interested in serving up my pylons app under Stackless Python - Stackless is more or less single-threaded so the model is somewhat like Twisted but without all the deferreds. Instead of threads, there are tasklets which participate in kind of a cooperative parallelism - as soon as one tasklet blocks, another tasklet is allowed to run until it blocks, and so forth. Ah, stackless ;) Since this is single-threaded, I have some concerns is with these 'global' objects that Pylons provides.. c, h, etc... These are normally thread-local storage right? Does pylons provide any capability to either: - provide a container so I can manage the thread-localness of them (I could store them in a tasklet-local storage) - provide a way to access them from environ rather than as a global? (then I could access them on a per-request basis, independent of what tasklet/thread they're run on) - avoid the use of them entirely? I suspect you're going to need to override some code to do things the stackless way using the stackless notion of thread local storage. Strangely enough, this same thing happened to me using a proprietary version of stackless in my framework Aquarium. If I were in your shoes, I might spend some time figuring out different ways to monkey patch things (either by making tasklets masquerade as threads or by swapping in some code into Paste). Just look at the code for what Paste is actually doing and figure out what you wish it were doing and see if you can do some magic to make it work. really I'd prefer that these things were just explicit in the request because otherwise it really ties pylons down to a multi-threaded or forked model. In Aquarium I made the design decision that you had to get everything from the ctx for exactly this reason. That's why Aquarium adapted to stackless so easily. However, the stacked object proxies are syntactically convenient--the cost is that they're tied to the normal Python threading API. Part of the reason I'm using stackless is that I can safely fire off multiple 'parallel' tasklets during a request which makes management of simultaneous database requests dirt-simple. Yep. But maybe I'm missing something? Anyone have any ideas here? You're a smart guy ;) You'll figure it out ;) Tell us how it goes.

I don't really have an answer to that yet, since I'm still fairly new to Pylons, but you could use a subdomain as well, which could work better. Maybe.

Re: Odd behavior with paster and Pylons

For some very odd reason that I can't discern, whenever I run paster inside of a Pylons command, even if I don't pass any arguments, it launches gconfd-2. Normally, I wouldn't notice, but WebFaction limits the number of long running processes you have, and I got e-mailed about it. To top off the weirdness, it only seems to run when X forwarding is set up. The easy solution is to disable X forwarding since it's useless, which I have, but I'm wondering if there's actually some sort of point to launching gconfd, since it doesn't appear to store anything. It probably has nothing to do with Pylons or Paster. It's probably gconf trying to forward settings over a socket or something when you're doing X forwarding.

Re: SQLAlchemy + MySQL + UTF-8 support - how?
On 5/29/07, David Smith [EMAIL PROTECTED] wrote: jj, I actually agree strongly with you regarding the potential dangers. My counter argument is that if you specify the encoding of the database in the config file to a different encoding than is in the mysql config file, don't you risk double-encoding anyway? Double encoding should *theoretically* never happen because MySQLdb knows if it has a unicode object or a UTF-8 string. Now that the bug is fixed in MySQLdb, and no other database needs such options, I'd prefer to promote the Unicode field as the proper way forward. SQLAlchemy should, via the MySQLdb module, determine at runtime the encoding of the database and translate from that encoding to unicode objects as necessary (as should any other ORM). To tell you the truth, I don't feel strong either way. As long as *I* the application developer don't need to do the encoding, and as long as the database and I agree about the encoding, it doesn't matter to me who does it. All the database drivers SHOULD support encoding for you. After all, not everyone uses SQLAlchemy. Personally, I think this should have gone in the DBAPI spec. However, if someone wants to let SQLAlchemy do the work, I don't have any objections.

I would say *don't* ;)
I wouldn't expect a SA object to be serializable. It just doesn't
make sense to me. I don't even want to think about complications with
the database and ACID, nor do I want to consider the scalability
concerns (the SA object should be tied to a particular SA session,
right?).
It just boggles my mind. I would say put some other non-SA-specific
object in the session, and then redo the SA stuff once you get it out
of the session.
(Of course, I could be wrong, but I don't think so.)

Hi Julien,
I went down the path you're going down too at one point. Then I
realized there's a reason that Kid and Genshi use HTML by default:
http://www.mozilla.org/docs/web-developer/faq.html#accept
http://webkit.org/blog/?p=68
Genshi let's you *type* XHTML, but *serve* HTML. It's the best of
both worlds. You can switch to serving XHTML as soon as IE actually
supports it and as soon as Mozilla stops telling you not to ;)
Of course, if you're a super advanced XHTML user doing something like
MathML, please feel free to ignore me! ;)

Re: Towards a more incremental test-driven-development in Pylons?
On 5/28/07, Agustin Villena [EMAIL PROTECTED] wrote: Hi all Researching patterns to test-driven-development in frameworks based on the model view controller, I found this interesting paper http://www.purpletech.com/articles/mvc/mvc-and-beyond.html In this pattern, there ios a mini-MVC for ecah page on top of the global MVC. Quoting Here, the Page Model (the Page Data objects) represents everything that will show up on the page, in what order, in what language, etc. The page model represents an overlapping set with the application model. It does not contain all the information in the application model, merely the subset that is necessary for the current page to render. However, it is not a subset, for it also contains other, additional information: for example, which user is currently logged in, or which page of search results is showing, or an error message based on an invalid field. The Page (View) Renderer objects, in turn, perform a transformation from the Page Data into HTML. The most logic performed by the Renderer should be no more sophisticated than simple conditionals or iteration on values and collections returned by the data model. Finally, the Page Servlet (Controller) receives the parameters, creates an appropriate Page Data (Model), and passes it to a Page Renderer (View).Thanks to this model, testing in very much incremental Quoting again Testability. MMMVC is much easier to test than previous architectures. You can test that the correct page model gets generated by passing known parameters to the controller and testing the page model it returns. You can also test the renderer by passing a known page model and testing its rendered output. Since UI testing is both more difficult and, arguably, less important (since errors in HTML rendering are more likely to be noticed by humans), you can reserve the bulk of your test cases for the page model. Indeed, some Agile programming teams either do not test the UI at all, or write only rudimentary UI tests; this shortcut is only desirable with a very thin UI layer on top of a full-fledged data model. For instance, if a Menu page must display the Soup du Jour (which changes every day), the page must not do Date today = new Date(); int dayOfWeek = today.getDay(); String soup = data.getSoupForDay(dayOfWeek); out.print(Soup du Jour: + soup); instead, that functionality must be delegated to the Page Model. Why? Because otherwise, it becomes impossible to test that Thursday's correct soup is displayed... unless you're testing on Thursday. out.print(Soup du Jour: + data.getSoupDuJour()); Note that getSoupDuJour() (with no parameters) is not a member of the application data model. You must add it to the Page Model. To apply this approach in pylons: 1) I must create a page-model oriented layer, that generates the specific data that the page controller needs. This is already easy in pylons 2) Given a frozen data-set, pass it to the page-view (template) and check if it is rendered in ehe appropiate way. Well, here is my problem. I don´t know how to make this kind of test. Any advice? Thanks I didn't read the link, but I can see what you're saying. Here are a couple tricks I can suggest: * To test your controllers somewhat in isolation, instead of calling render_response, call my_render_response which you write yourself. In my_render_response, in testing mode, you can simply return JSON, and, in real mode, you can return a real page. Then, you can test the data in the JSON--i.e. the page model. * Alternatively, in your site-wide layout, take the entire c object, serialize it and shove it in an HTML comment. Then, write a script that can look for the HTML comment and deserialize it. Wham--you suddenly have a way to grab the entire c object from the HTML of any generated page. Of course this doesn't work for redirects or when you're generating something other than HTML, but I think that's okay. * I've seen a real test-driven development shop in action using Ruby on Rails. The way they did it was to use pre-arranged data in the database and then test for the presence of data at specific places in the HTML DOM like. For instance, #name 'Charlie Tuna' asserts that there must be a name element which contains the known string Charlie Tuna. This kind of testing is fully automated, of course. Does that help?

Re: Class nesting or subclassing controllers
Just move you subclass into a different module, and it'll be fine. By the way, I'm a little bit confused about logically separate and group link hierarchies. Naturally, your link hierarchies don't have to match the code. Maybe I'm just understand what you mean.

Re: abort(), detail and the error controller
On 5/26/07, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: Hello! I am working on my first real Pylons application and so far everything is going really good! Big thanks to all those involved for creating such a great web framework. I am just getting to adding users to my application. I want to stop users from viewing data that isn't their own. My gut reaction is to abort() and setup my error controller to display the error in a way that fits in with the rest of my application (using my Mako templates). But I want to give the user a specific message about why they can't go there. So, I tried: abort(403, Can't access another users data) The second argument is detail which gets passed to the paste.httpexceptions.HTTPForbidden object and thrown. This seems like a really useful place to keep an application specific message. However, when the exception is converted to wsgi response by the paste.httpexceptions middleware, this information is lost. So, that isn't going to work. My questions are: (1) Is the exception object stored anywhere? It would be great if it was dropped into the environ somewhere, but best I can tell from the paste source code, it isn't. (2) Is there a better way to do this? I imagine having lots of errors like this with simple one line messages. I could create my own middleware to catch application specific exceptions and forward them, but this seems like overkill. Is there a suggested way to accomplish this? Thanks in advance! Yep, I've encountered this same difficulty. In your case, probably the best thing to do is to do a render_response using an error template. If you *really* want to take matters into your own hands, write your own middleware that *wraps* the Paste exception handling middleware. I didn't do that, although I've done it for other things. Also, see the trick I wrote about here: http://jjinux.blogspot.com/2007/03/python-returning-multiple-things-of.html When I wrote that, I was facing the same issue you are facing.

Re: Common files for a multi-app

I'm trying to find out what the best way is to reference common css/javascript files across all of the apps. Here is the setup in a nutshell: I have a home page and 3 sub-apps that all use the same css layout files and some of the same script files. I have so far been putting these files in each application's public directory. Bad idea, I know, but I was in a hurry. Anyway, the 3 apps really are separate apps and I therefore don't really want to put all of them in the same project. I currently use paste#urlmap to call out to each separate app. Just wondering if anyone has tried to do something similar and found a good way to share some of these files across multiple apps. I have a project called lookandfeel that defines the common look and feel for all the other Web applications. In each of the other applications, in their websetup.py, it calls some setup function from lookandfeel that creates symlinks. I use one symlink for the public directory, and one symlink for the templates directory. Later, when I install the apps, I can run paster setup-app myapp, and it'll create the symlinks. There's only one gotcha--make sure you create the eggs from a clean checkout. Otherwise, the egg creation process will follow the symlinks, which isn't what you want.

Excuse my newbiness, but could you explain your method further? where is site.py? The declaration for working with encodings in Python files is described here, in PEP 263: http://www.python.org/dev/peps/pep-0263/ The site.py is normally located in your base library directory, for me on Debian Linux it is /usr/lib/python2.4, or maybe even /etc/python2.4/site.py Search for the string ascii in the file, and then you can see why it is very hard to change the default encoding after this file is executed. And site.py is automagically executed everytime you start python ;) But, as I said, it is cumbersome, because you must have access to the site.py file, and this isn't guaranteed, especially for a shared hoster. There exists another solution, at least for normal python applications: You can place a file called sitecustomize.py in the directory of your application (or maybe in the first library path for it, I'm not sure, but that is normally the application path), where you can put in something like that: snip import sys sys.setdefaultencoding(UTF-8) snip This works as well. I normally don't use it, and especially haven't used it with pylons (because I'm actually on this list because I had a Myghty caching question, and somehow stayed ;) ), but this is the only solution python applications compiled with py2exe, as you have no other method of setting the site.py there. But, as I said, I don't know how it would work in pylons, maybe someone with a broader knowledge in pylons can look at it.

Re: widgets
Please, advise some widget framework to use with Pylons, I know there is in turbogears. I'd like to here some recommendations before I start learning Toscawidgets because it's only alpha stage now. Maybe there are more mature/promising widget frameworks suitable for Pylons. In the Python world, ToscaWidgets is your only option. However, if you forsake the idea of eggifying things, you can just use various JavaScript widget libraries. Both Dojo and yui-ext have nice looking widgets.

You may wish to not use that option.
From the Mako docs (
http://www.makotemplates.org/docs/unicode.html#unicode_handling
):
Note that the built-in decode object is slower than the unicode
function, since unlike unicode its not a Python builtin, and it also
checks the type of the incoming data to determine if string conversion
is needed first.
If you comment that out and you start getting unicode errors, it's
likely because your strings aren't being converted to unicode objects.
I had trouble indeed. But I'm willing to come back if that's happening
again.
You can either decode them yourself (one variable at a time
via .decode('utf-8') ), or you can have request.params output to
unicode (see
http://pylonshq.com/project/pylonshq/browser/Pylons/trunk/docs/internationalization.txt#L516
) along with SQLAlchemy (use_unicode=True in either create_engine or
make_session).
Where (in a standard Pylons project) would I set use_unicode=True? I
just found references to create_engine in the websetup.py which is
obviously not the right place. And my models/__init__.py just has the
line
meta = DynamicMetaData()
I fought long and hard with this problem. Back then, it turned out
that letting SQLAlchemy do the encoding with use_unicode=True wouldn't
work because of a bug in MySQLdb. However, it looks like that bug has
been fixed in a recent release of MySQLdb.
These days, I bet you can just add ?use_unicode=1 to the end of your
db uri, and it'll work.

Have a look at the docstring in config/routing.py. It sayeth:

So, at a guess, you might want to try a re-ordering:
map.connect('hello1', controller='hello', action='index')
map.connect('hello2', 'test', controller='hello', action='test')
map.connect(':controller/:action/:id')
map.connect('*url', controller='template', action='view')
(Note, I removed the leading / from /test, going by my own
routing.py contents)
HTH
Cheers,
Graham.
I'm no Routes expert, but is it really supposed to say:
map.connect('hello2', 'test', controller='hello', action='test')
It seems like 'hello2' shouldn't be there.

If you're using Apache, you can have one part of the site served by PHP and another proxied to paster. Alternatively, Paste has support itself for proxying to another application.

Re: Unicode trouble with formencode, Mako and UTF8
On 5/8/07, Christoph Haas [EMAIL PROTECTED] wrote:
Dear list...
I'm learning how to use Formencode to validate the input of the HTML
forms I use. Unfortunatly I have some breakage that I don't know how to
fix.
My controller:
===
class DhcpZoneForm(formencode.Schema):
allow_extra_fields = True
filter_extra_fields = True
new_network = formencode.validators.URL(not_empty=True)
class DhcpController(BaseController):
def new(self):
return render_response('dhcp/new.mako')
@validate(schema=DhcpZoneForm, form=u'new')
def new_form(self):
return Response('Your network is: %s' %
self.form_result.get('new_network'))
===
The Mako template is pretty straight forward. Just a HTML form that is
supposed to call the new_form action with text fields where one field
is new_network.
Mako template:
===
# -*- coding: utf-8 -*-
%inherit file=/base.mako/
h1New DHCP zone/h1
${ h.form(h.url_for(action='new_form')) }
table
tr
thNetwork/th
td${ h.text_field('new_network') }/td
/tr
tr
thComment/th
td${ h.text_field('new_comment') }/td
/tr
tr
thStandard Lease Time/th
td${ h.text_field('new_standard_lease') }/td
/tr
/tr
tr
thMaximum Lease Time/th
td${ h.text_field('new_maximum_lease') }/td
/tr
/table
${ h.submit() }
/form
===
Now the error that I get is:
===
File 'string', line 1 in lambda
File '/var/lib/python-support/python2.4/pylons/decorators/__init__.py', line
106 in wrapper
response.content = [htmlfill.render(form_content, params, errors)]
File '/usr/lib/python2.4/site-packages/formencode/htmlfill.py', line 70 in
render
p.close()
File '/usr/lib/python2.4/site-packages/formencode/htmlfill.py', line 235 in
close
self._text = ''.join([
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 10:
ordinal not in range(128) the form was passed in as an encoded string, but
some data or error messages were unicode strings; the form should be passed
in as a unicode string
===
In the debug window I clicked on the '' to see which code broke:
===
try:
self._text = ''.join([
t for t in self._content if not isinstance(t, tuple)])
except UnicodeDecodeError, e: self._text = ''.join([
===
So I thought it's the self._content that is not correctly encoded in
unicode and had it print in the debug window. Among many other lines I
also found parts like these:
===
'li class=navtitel',
'Host-Eintr\xc3\xa4ge',
'/li',
===
This is a german text that means 'Host-Einträge'. Shouldn't that string
rather be u'Host-Einträge'? What have I missed? I told Mako to use UTF8:
config/environment.py:
===
# The following template options are passed to your template engines
tmpl_options = {}
tmpl_options['mako.input_encoding'] = 'UTF-8'
tmpl_options['mako.output_encoding'] = 'UTF-8'
tmpl_options['mako.default_filters'] = ['decode.utf8']
===
Help! :)
Kindly
Christoph
I've seen this happen on the mailing list a couple times recently, but
since I don't use Mako or htmlfill, I don't remember the answer. You
may be able to figure out the result by looking in the archives.
Best of Luck,
