Django role based views?

Question

I\'m looking for some input on how others would architect this. I\'m going to provide class (django group) based views.

For example, a user\'s group will determine

We used a role base system for a similar problem. Basically users have permissions to assume different roles.

View functions got decorated:

def needs_capability(capability,redirect_to="/cms/"):
   def view_func_wrapper(view_func):
       def wrapped_view_func(request,*args,**kwargs):
           if not request.role._can(capability):
              return HttpResponseRedirect(redirect_to)
           return view_func(request,*args,**kwargs)
       return wrapped_view_func
   return view_func_wrapper

The rest of the magic is inside the request.role attribute which got set inside a context processor. Authenticated users got a Role, for the unwashed masses a DummyRole.

Access to information was restricted further inside the templates:

 {% if not request.role.can.view_all_products %}
          Lots of products, yeah!
 {% endif %}

Not the cleanest solution in my opinion, but worked as expected.
