Джанго Логин - получение AttributeError не может установить атрибут

Question

Я получаю следующую ошибку каждый раз, когда я пытаюсь войти на локальную копию моего сайта Джанго:

Environment: 


Request Method: POST 
Request URL: http://127.0.0.1:8000/users/process_login/

    44.    self.session_key = self._get_new_session_key() 

Exception Type: AttributeError at /users/process_login/ 
Exception Value: can't set attribute 

, И Exception Откуда:

Exception Location: /Library/Python/2.7/site-packages/mongoengine-0.6.1-py2.7.egg/mongoengine/django/sessions.py in create, line 44 

Используя pdb, я отлаживал его немного дальше. В login(request, user) методе:

def login(request, user): 
56   """ 
57   Persist a user id and a backend in the request. This way a user doesn't 
58   have to reauthenticate on every request. Note that data set during 
59   the anonymous session is retained when the user logs in. 
60   """ 
61   if user is None: 
62    user = request.user 
63   # TODO: It would be nice to support different login methods, like signed cookies. 
64   if SESSION_KEY in request.session: 
65    if request.session[SESSION_KEY] != user.id: 
66     # To avoid reusing another user's session, create a new, empty 
67     # session if the existing session corresponds to a different 
68     # authenticated user. 
69     request.session.flush() 
70   else: 
71    request.session.cycle_key() 

SESSION_KEY его нет, так request.session.cycle_key() называется, и где-то там он появляется AttributeError брошено (

Является ли это проблема с моей связью Монго я тыкать? вокруг, но я не могу понять это
