Question

I need to implement user rights for user groups (pretty similar to facebook groups). For example, each group can have members with rights like: can_post, can_delete, can_ban, etc. Of course, one user can be a member of many groups and group can have many different users with different rights.

What models I need for this functionality?

Answer 1

Django has a built in groups system. Whenever you have a question like this, I recommend searching the Django docs, which are extensive, helpful, and well written.

So long as you are using the django.contrib.auth app, you have access to groups. You can then assign permissions to those groups.

from django.contrib.auth.models import User, Group, Permission
from django.contrib.contenttypes.models import ContentType

content_type = ContentType.objects.get(app_label='myapp', model='BlogPost')
permission = Permission.objects.create(codename='can_publish',
                                       name='Can Publish Posts',
                                       content_type=content_type)
user = User.objects.get(username='duke_nukem')
group = Group.objects.get(name='wizard')
group.permissions.add(permission)
user.groups.add(group)
