Please update your question to include what you've tried and researched then. You need to give your url a name and then use that name. — Sayse

As @Sayse says in his comment, documentation told you to give your view a name to use reverse lookup. To understand how it works you need to look at django.core.urlresolvers.RegexURLResolver#_reverse_with_prefix method. Here in line 462 (Django 1.9) it executes possibilities = self.reverse_dict.getlist(lookup_view), where lookup_view is your 'views.login' argument of url template tag. So you don't have this name - it wont work.

Hovever, you can use full dotted path to your view like this:

{% url 'path.to.some_view' v1 v2 %}

Not views.view but app.views.view. But you should not do this since it is deprecated and will removed in Django 1.10. Hope it will help you.
