In Django templates, is there a variable in the context (e.g. {{ BASE\_URL }}, {{ ROOT\_URL }}, or {{ MEDIA\_URL }} that one can use to link to the home url of a project?
I.e. if Django is running in the root of a project, the variable (let's call it R) {{ R }} in a template would be /. If the root url is a sub-folder http://host/X/ the variable {{ R }} would be /X/ (or http://host/X/).
It seems painfully simple, but I can't find an answer. :) Thank you!
You could give the URL configuration which you're using to handle the home page a name and use that:
urls.py:
from django.conf.urls.defaults import *
urlpatterns = patterns('myproject.views',
url(r'^$', 'index', name='index'),
)
Templates:
<a href="{% url index %}">...
UPDATE: Newer versions of Django require quotation marks around the name of the view:
<a href="{% url 'index' %}">...
