Re: Simple production question
Thanks to all for yours replies. If I understand correctly, your Pylons application is running on port 8080, and you want Apache to proxy port 5001 to it but not port 80 (i.e., port 80 will be used for a different website). Excuse me for my bad English. I dont' explain well the problem. The Pylons applications is running on port 5001. But there aren't problems to change the port to another (over 8000). I wrote a lot of CherryPy applications where I set the port, start its server and that's all. Using Pylons, seems to be better use a web server (like Apache) to serve the application instead using Paster directly. Now, I have an Apache web server that serve the main web site of our center and other virtual sites. So, I haven't a domain to bind to Pylon application but only a port. My question is: is there a way to configure Apache to proxy calls to the specific port where Paster is running?

External link for form action
Dear all, I'm going crazy but I'm unable to find how can I set an external link for a form action. In my Pylons application I created a form that have to be processed by a credit card security site. So in form action=... I had put the external link directly. But it doesn't work. When I click on the submit button, nothing happen. How can I do that?

Has Python 3's performance caught up to Python 2's yet? For a while the I/O system was in Python though I think it's in C now, but the last stats I saw showed Python 3 running slower. Sorry, I meant to say performance in some areas, like systematic returning iterators instead of lists e.g for dict.keys, map(), filter(), etc. For the general performance profile I believe you are right, py3 is still slower... But, name me *one* py3 feature for which a legacy package *must* have ?!? You can say the same about Python 2.6 features, Python 2.5 features, etc. You don't *have* to use them and some people don't care, but other people do and would like to use the features. For instance, named tuples and defaultdict, which were added in 2.6. I had to reimplement defaultdict in WebHelpers so it would be compatible with 2.5. I still haven't used named tuples yet because we only switched to Python 2.6 at work a few months ago. But, the key point here is *legacy*... in general you want to make a legacy (working, deployed) package available to py3 world for the benefit of applications that wish to migrate to py3 and need to carry over the dependency, and *not* to selfishly take advantage of the benefits of the new language version. Presumably, if anything is working in 2.5, it can be made to work on both 2.5 and 3.0 from the same code base, without deprecating anything in the 2.5 version or without back-porting any features of the new lang version. Of course if you want to back-port some 3.0 feature into your 2.5 version, then special work as you describe is needed... but then the question does not anymore concern support for 3.0 but whether you still want to support 2.5 and for how long. For the defaultdict example, it would be another type defn that will be obtained differently when running under 2.5 as opposed to when running under 3.0. m. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

MikeB is not a framework developer. He's a database guy who has also written a remarkable template engine, Hey, so did I ;-) And actually I do not say that lightly -- I still have to come across a templating task that can be done in Mako or any other python templating system and that cannot be done in Evoque -- on the contrary, in general it is done more simple and direct in Evoque. Even if you consider Evoque's limitation of handling only python expressions (i.e. no statements), in practice this is never a concern -- anything requiring a statement is in external pure-python (trusted) modules. The (big) gain... is that Evoque can be sandboxed (i.e. let your untrusted user modify the template source!), a feature that no other templating system had *designed-in* from the start. Anyhow, paying honour to Mako as the reference templating in python, here's a summary of differentiating features of Evoque: http://evoque.gizmojo.org/features/unique/ Plus, it is almost a year that it runs under python 3, as well as python 2.4+, from the same codebase. m. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups pylons-discuss group.

Re: redirect after download?
Gentlemen, Thanks again for your illuminating responses. As you have no doubt surmised, most of the problem is that I don't know what I'm doing! I'm not doing anything esoteric; I'm just a re-noob whose last serious foray into web apps was with cgi/perl over ten years ago. So I'm sure that the things I want to do are pretty standard...it is just that I'm woefully ignorant. Having said that, I've found Pylons a fairly comfortable ride, and put up most of the app without too many issues. I did note Matt's suggestion of the META tag in an earlier email, but a quick google search didn't yield anything that I was able to connect with downloading. But as you've indicated that this is a common solution, I will take a better look this time around. I don't mind reading documentation; sometimes the problem is not knowing enough to be able to ask the right question. Mike's suggestion about the redirect is also interesting, and immediately made sense. I appreciate the pointers!

What does View Source show in the browser? The behavior is
consistent with form action= method=POST /, which could happen
if url_for returned None. That in turn would indicate it couldn't
match the route name, and then we'd have to investigate why.
Also, what happens if you replace the h.url_for call with
``url('credit_card')``. url_for is gradually being replaced by
pylons.url, which has a different implementation and thus may behave
differently.
Another possiblility is that a different route is matching, something
earlier in the route definitions.
As a workaround, you can use a 'c' variable for the URL. Routes does
not provide much advantage for external URLs, other than the
convenience of defining them in the route map.

or create a pylons directory as standard, for example:
/etc/pylons/myblog.ini
/var/lib/pylons/myblog/...
...
It's possible?
There are no official RPM instructions or directory layout for Pylons.
In this case, I would avoid over-engineering and scattering files
across multiple directories. If this app will be used only by a few
sysadmins who know Pylons (or will get to know it during the time they
administer the site), just put the entire app in one directory. The
best choices are /usr/share/myblog or /usr/share/pylons/myblog
following the precedents of:
PHPMyAdmin: /usr/share/phpmyadmin
Emacs: /usr/share/emacs/site-lisp
Vim: /usr/share/vim/{addons,vim72}
PHPMyAdmin puts its configuration files in /etc/phpmyadmin (the Apache
config and the equivalent of production.ini). The main Apache
configuration simply includes /etc/phpmyadmin/apache.conf. But Apache
could simply set its DocumentRoot to /usr/share/phpmyadmin and that
would work too.
All documentation should go under /usr/share/doc/[pylons-apps/]myblog
per the Filesystem Hierarchy Standard (http://www.pathname.com/fhs/).
Samples of the configuration files can also go here.
I set up my sites differently than this. I don't use RPM/DPKG. I put
applications under /home/wwwadmin/apps (Subversion checkouts) and
virtualenvs under /home/wwwadmin/venv . Data files go under
/home/wwwadmin/data . The INI files stay with their applications
(/home/wwwadmin/apps/myblog/production.ini). The apps all run under
Supervisor using their appropriate virtualenv. Apache and Supervisor
configurations are kept under /home/wwwadmin/apps/servers/all, and
hand-copied to /etc. (My rule is that anything executed by root must
be hand-copied from the apps directory to its proper location, while
webapps running as www-data can be run directly from the apps
directory.)

Repeating elements and htmlfill
Hi,
htmlfill.render() doesn't seem to handle repeating elements as I
expect. I've boiled my code down to this example:
import formencode.htmlfill as htmlfill
template = 'input id=weightings-0.weight
name=weightings-0.weight type=text value= /'
print htmlfill.render(template, defaults={'weightings':
[{'weight': 1.0}]})
print htmlfill.render(template, defaults={'weightings-0.weight':
1.0})
Output:
input id=weightings-0.weight name=weightings-0.weight
type=text value=/
input id=weightings-0.weight name=weightings-0.weight
type=text value=1.0 /
See how the first render fails to populate a value. Am I doing
something wrong? I've using version 1.2.1.
Are there any good examples out there? Chapter 6 of the 1.1 book
covers some of this but it's not complete (it also has a bug unless
I'm missing something - person and people are used
inconsistently).
Thanks,
Mike

Re: Repeating elements and htmlfill
Yeah as far as I know it does not work like that for the first case.
You need to preprocess your defaults with
formencode.variabledecode.variable_encode() to change the first case
into the second case.
I'm still working on a good repetitions example, are you using
javascript? You should look at formencode's NestedVariables,
variable_encode and variable_decode to start.

I did plan to use Javascript, then I took a closer look at the 1.1 book and thought I'd see how I would get on with the approach outlined there. After struggling a little I decided to play it safe and not add rows dynamically (by either method) to start with. Either way, the need to populate the form with data remains. I have NestedVariables and ForEach in my parent form schema, but (in my code at least) they don't come into play until validation time. Anyway, I hope to understand this a bit better after following your first piece of advice. A really solid good example of this would brilliant. Forms in Pylons do take a bit of getting used to (which is about the worst I can say about what has been a positive experience for the most part)!
