Why doesn't the {{ site.domain}} tag work in a Django template?

Question

Django

I'm trying to get the domain name through the template tag:
<form action="http://{{ site.domain }}" + "...">
But an empty url is rendered:
<form action="http://">
What and where else should I do to make it work?
UPD
'django.contrib.sites' is available

Answer 1

{{}}is not a tag, it's a variable substitution expression. Apparently, there is no variable in the context site. You can pass it in from a view, write your own context processor, or use django.contrib.sites.middleware.CurrentSiteMiddleware .
