Django, request.user is always Anonymous User

by

The request.user is set by the django.contrib.auth.middleware.AuthenticationMiddleware.

Check django/contrib/auth/middleware.py:

class LazyUser(object):
    def __get__(self, request, obj_type=None):
        if not hasattr(request, '_cached_user'):
            from django.contrib.auth import get_user
            request._cached_user = get_user(request)
        return request._cached_user

class AuthenticationMiddleware(object):
    def process_request(self, request):
        request.__class__.user = LazyUser()
        return None

Then look at the get_user function in django/contrib/auth/__init__.py:

def get_user(request):
    from django.contrib.auth.models import AnonymousUser
    try:
        user_id = request.session[SESSION_KEY]
        backend_path = request.session[BACKEND_SESSION_KEY]
        backend = load_backend(backend_path)
        user = backend.get_user(user_id) or AnonymousUser()
    except KeyError:
        user = AnonymousUser()
    return user

Your backend will need to implement the get_user function.
