pdb を使用して、もう少しデバッグしました。login(request, user)メソッドでは：
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は None であるため、request.session.cycle_key()呼び出され、そこのどこかに AttributeError がスローされているように見えます (
これは私のmongo接続に問題がありますか? ぐるぐる回ってるけどよく分からん
