A slightly improved version of snippet #195 which keeps the logic but makes use of the simple_tag decorator to drastically simplify the code.

For an alternative to this sort of tag, check out the media context processor in my template_utils app.

        return urlparse.urljoin(settings.MEDIA_URL, path)
    return ''

register = Library()
register.simple_tag(media_path)

This is now obsolete. You only need to import RequestContext in your views:

from django.templates import RequestContext

And then add a context_instance to your render_to_response, like so:

return render_to_response('main/main.html', {"variable": 0}, context_instance=RequestContext(request))

You can now access the media url anywhere with {{ MEDIA_URL }}
