Django-registration & Django-Socialauth
There shouldn`t be any problems there. Django-Socialauth adda new auth backends, and it should works fine with permissions and decorators. And Django resistration just register a user on site, so unless you remove standard auth backend, it will work fine too.
Have anyone used these 2 django apps together? I want to know how well these 2 gel together along with Django's User Authentication system.
When I mean Django's User Authentication System, I mean I should be able to use decorators like @login_required or grant permission to specific views (or functions in views.py) based on who the user is.
