When I create a user in Django, he has no permissions:
In [7]: u = User.objects.create(username='aoeu')
In [12]: u.user_permissions.all()
Out[12]: []
I want some permissions to be set by default (say, 'api.add_item'), and I use Django Guardian. Is this possible to do in a declarative way, eg. without writing a post_save signal?
No, it is not possible. Check django.contrib.auth code to ensure
