reverse/url tag assumes view is a module-level callable

[miracle2k]

django.core.urlresolvers.reverse, when called with a string argument, requires that string to reference a view inside a module, which means that the following won't work, since site is a class, and admin is the module.

reverse('django.contrib.admin.site.root')

The faulty code is get_callable inside urlresolvers.py.

Reversing stuff in AdminSite is a much larger problem that needs to be dealt with later on.

This is really fiddly to handle all the cases, since it requires stepping through one dotted piece at a time checking if it's something to import or a class or whatever. Since reverse-resolving is already slow to start up as it is, it's not really worth it.

The correct thing to do here is to use the named URL-pattern form:

url(r'^admin/(.*)', admin.sites.root, name='my-admin-root'),

and then {% url my-admin-root "" %} will do work as you expect.

It's arguably a bug that the empty string is needed if you only want the root, but that's an issue with reverse() and I've opened #9239 for that.
