User groups and permissions
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, Permissionfrom django.contrib.contenttypes.models import ContentTypecontent_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)
