Feature Request: allow toggling sharing for user/group on and off

Hello!

I have custom User model, which inherits AbstractBaseUser and doesn’t have Group relation. So when i use filter mixin, i get this exception:

Traceback (most recent call last):
  File "python2.7/site-packages/advanced_filters/admin.py", line 34, in lookups
    return AdvancedFilter.objects.filter_by_user(request.user).filter(
  File "python2.7/site-packages/advanced_filters/models.py", line 13, in filter_by_user
    return self.filter(Q(users=user) | Q(groups__in=user.groups.all()))
  File "python2.7/site-packages/django/utils/functional.py", line 235, in inner
    return func(self._wrapped, *args)
AttributeError: 'User' object has no attribute 'groups'

Can you add a attribute checking in UserLookupManager.filter_by_user or something?

I created a PR for it. It was easy enough. I want to use this plugin maybe. I’ve been playing around with it. It’s quite nice, however a bit complex to use. Ok for developers but more complex for managers.

But I understand that it’s not easy to make a user-friendly UI in the Django admin. It’s not great but with a bit of modification and plugins it is just good enough to not make a custom admin yourself. At least it saves some work for as long as it suffices.

So thanks for the plugin. I hope this PR is will be accepted and that the plugin will be accessible to more people. Maybe I’ll do some more hacking on this some time.

Cheers

Yep that’s a good idea, and we should also allow toggling the sharing (and related filtering) for user/group in settings.

P.s: Pull requests are welcome 😄
