How to perform Template() on askbot setting?
I'm pretty new to Python, and Django is even more unfamiliar, but I was trying to find a simple hack that would process a text-based askbot setting using the Django Template() function, specifically here:
http://askbot.org/en/question/519/faq-to-settings
Where what I would like to do something remotely like:
if getattr(askbot_settings, 'FORUM_FAQ',''):
faq = Template(FORUM_FAQ)
return render_into_skin(faq, data, request)
which of course doesn't work for various reasons. My question is, what exactly are the intermediate steps to get something like this to work, so that FORUM_FAQ can contain template tags like {{settings.MIN_REP_TO_VOTE_UP}}, be processed to replace these tags, then fed into an HTTP request like faq.htm?
It seems like it should be pretty easy, but again, I don't know either python or django (or askbot) well enough to figure it out.

Ooooooooo!
I got it! Sorry for being so dense. Here is the code that works:
def render_text(text, data, request):
context = RequestContext(request, data)
skin = get_skin(request)
template = skin.from_string(text)
return template.render(context)
This works with both {{settings.SETTING}} and {% trans %} foo {% endtrans %}
Yay :)

Okay, I figured it out... I wasn't importing Template :)
Once I import Template, I add this to loaders.py:
def render_text(text, data, request):
context = RequestContext(request, data)
template = Template(text)
return template.render(context)
And now I can send the text there first, then to render_into_skin.
The only problem I have with this is {% trans %} tags don't work. Otherwise, you can at least include settings variables now.

In askbot, because of the skins module, you need to do this:
from askbot.skins.loaders import get_template
from django.template import Context
template = get_template('some_template.txt')
output = template.render(Context({'some_data': 'some_value'}))
Here are docs for Jinja2. Jinja2 templating engine is used throughout askbot for the speed.

Okay, this isn't an answer, this is a continuation of the above comments, but I need room to post code :)
Here's my code, at the end of loaders.py:
def render_text(text, data, request):
env = Environment(extensions=['jinja2.ext.i18n'])
template = env.from_string(text)
context = RequestContext(request, data)
return shortcuts.render_to_string(template, context)
and it returns an error:
dictionary update sequence element #0 has length 1; 2 is required
