Comment:
Django actually prevents this by design. The idea is to keep most of the
logic in views and keep the template language as simple as possible (so
that it can easily be used by non tech-savvy designers, for example).
Quoting from the doc:
"Because Django intentionally limits the amount of logic processing
available in the template language, it is not possible to pass arguments
to method calls accessed from within templates. Data should be calculated
in views, then passed to templates for display."
(https://docs.djangoproject.com/en/1.3/topics/templates/#accessing-method-
calls)
So you'll have to do that in the view. Writing a custom template tag or
filter might also be of good help. This is a common problem, so don't
hesitate to ask on the django-users mailing list for more advice.
