If no ``obj`` is given, ``False`` is returned. .. note:: Remember, that if user is not *active*, all checks would return ``False``. Main difference between Django's ``ModelBackend`` is that we can pass ``obj`` instance here and ``perm`` doesn't have to contain ``app_label`` as it can be retrieved from given ``obj``. **Inactive user support** If user is authenticated but inactive at the same time, all checks always returns ``False``.
