Please need some help on this. Following is my error traceback.I'm using gaesessions with django 1.2 on GAE. I'm getting following error:

    Traceback (most recent call last):

AttributeError: 'WSGIRequest' object has no attribute 'session'

On one link it is working. There is no error but on another above error is shown. When I debug the code using pycharm 'process_request' function of the 'DjangoSessionMiddleware' is never entered. I don'tknnow what is the problem. Please any one can help?

From https://github.com/dound/gae-sessions#readme :

If you want to gae-sessions with Django, add 'gaesessions.DjangoSessionMiddleware' to your list of MIDDLEWARE_CLASSES in your settings.py file. You can then access the session associated with the current request via the request.session variable. To configure the Django middleware, modify the following line in gaesessions/__ init__.py:

self.wrapped_wsgi_middleware = SessionMiddleware(fake_app, cookie_key='you MUST change this')

I have faced this error quite a few times. The reason for this error is incorrect code indentation in views.py.
