19147	session.session_key is None for signed_cookies sessions on first request	rwmcfa1	nobody	"SessionBase defines:

    def _get_session_key(self):
        return self._session_key

and sets up a property, session_key to use it

    session_key = property(_get_session_key)

signed_cookies.SessionStore overrides _get_session_key and comments as to why.

the problem is that the property, session_key calls the parent class method (SessionBase) rather than the signed_cookies.SessionStore version. that's not destructive in this case since the parent class one just returns the current value, but it causes things that look for the session_key (request.session.session_key) to get the wrong answer (None) on the first request. subsequent requests will see the correct value.

fix, though maybe less than ideal, is to re-define the property at the bottom of signed_cookies so that the descendant class's method will be called.

        session_key = property(_get_session_key)
