If you have a model with foreign key to User, you can use this manager to show (i.e. in admin interface) only objects, that are related to currently logged-in user. Superuser sees all objects, not only his.

Requires: ThreadlocalsMiddleware

                return query_set.filter(**{ '%s__exact' % self.fk_field_name: current_user })

        return query_set

# Example usage

class TestModel(models.Model):
    owner = models.ForeignKey('auth.user')
    objects = UserManager('owner')
