Use WTForms with webapp and Django templates on Google App Engine
Question: I'm trying to use WTForms with webapp without much luck.

I would like to be able to use the `form_field` templatetag, as shown in the
documentation:

`{% form_field form.username class="big_text" onclick="do_something()" %}`

I've got WTForms installed fine in my application, but its Django template
tags isn't working for me. Does anyone have instructions on how to get this
installed?

If I can't get this working, I will probably give up and switch to Jinja2
templates. The reason we have kept with Django so far is to limit the number
of dependencies as much as possible.

Here's what I've tried so far:

I've install Django 1.1 locally and enabled it [per the
documentation](http://code.google.com/appengine/docs/python/tools/libraries.html#Django).

I tried adding `INSTALLED_APPS = ['wtforms.ext.django']` to my `settings.py`
\- no effect.

I tried registering the wtforms templatetag manually:.

    
    
    register = webapp.template.create_template_register()
    
    from wtforms.ext.django.templatetags import wtforms
    
    register.tag('form_field', wtforms.do_form_field)
    

This gave me an error: `InvalidTemplateLibrary: Could not load template
library from template_helpers, No module named django.templatetags`

So I tried copying and pasting the template tags into my own code, and I got
the error `TemplateSyntaxError: Could not parse the remainder: ' form.foobar'
from 'form_field form.foobar`.

However, I don't think the templatetag registration worked, because the error
was the same without that code.

**Update:** I'm leaving this question up in case someone on the internet can
some day answer it, but I switched to Jinja2 and now everything works
perfectly. Webapp with Django templates is dead to me. ;-)


Answer: I recommend jinja2 templates over django: <http://jinja.pocoo.org/> It's based
on the django templates but more powerful and easy to use. I don't think it's
a good idea to use Django templates without the django stack. Also, if you
want a more structured framework, a VERY nice minimalist framework is Flask:
<http://www.pocoo.org/projects/flask/#flask>. I can't praise those two
libraries enough. I worked a long time in Django and found this combo to be
very refreshing and succinct.

P.S. this should be a very simple process to port over. It took me 10 minutes
to port over a webapp site when I just found out about Flask.
