Session backend is broken in django 1.4

[ghost]

The stable release 1.4 from django broke the session backend from mongodb.

mongoengine/django/auth.py:
class SessionStore(SessionBase):
def create(self):
while True:
self.session_key = self._get_new_session_key()
....

This will throw an attribute error when accessed. Following change is needed to make it work again:
self._session_key = self._get_new_session_key()

Duplicate, sorry about that.

I have the same problem. And just from the merger of remote update down over the code, I cleaned up the browser's cookie, or can's set attribute. in the source code to test shows, the fundamental can't arrive home.

I have a answer. I have a python virtualenv. beacause the virtualenv project is wrong. if don't python's verison no problem, so you can mkvirtualenv new project. eg: $mkvirtualenv dev #then pip install packages $ rmvirtualenv olderbranch # delete older project env. try it.
