Description: django-cached_authentication_middleware is a drop in replacement for
        ``django.contrib.auth``'s built in ``AuthenticationMiddleware``. It tries to
        populate ``request.user`` by fetching user data from cache before falling back
        to the database.
        
        Installation
        ------------
        
        |Build Status|
        
        
        * Install via pypi::
        
            pip install django-cached_authentication_middleware
        
        * Configure ``CACHES`` in django's ``settings.py``::
        
            CACHES = {
                'default': {
                    'BACKEND': 'django.core.cache.backends.memcached.PyLibMCCache',
                    'LOCATION': '127.0.0.1:11211',
                    'TIMEOUT': 36000,
                }
            }
        
        * Replace ``django.contrib.auth.middleware.AuthenticationMiddleware`` with
          ``cached_auth.Middleware`` in ``settings.py``::
        
            MIDDLEWARE_CLASSES = (
                'django.middleware.common.CommonMiddleware',
                'django.contrib.sessions.middleware.SessionMiddleware',
                #'django.contrib.auth.middleware.AuthenticationMiddleware'
                'cached_auth.Middleware',
            )
        
        And you're done!
        
        Cached Auth Preprocessor
        ------------------------
        
        Sometimes you want to preprocess to ``User`` instance before storing
        it into cache. ``cached_auth`` allows you to define
        ``settings.CACHED_AUTH_PREPROCESSOR``, a callable that takes two arguments, ``user`` & ``request`` and returns a ``User`` instance.
        
        A classic example of this would be to attach ``Profile`` data
        to ``User`` object so calling ``request.user.profile`` does not incur a
        database hit. Here's how we can implement it.
        
        .. code-block:: python
        
            def attach_profile(user, request):
                try:
                    user.get_profile()
                # Handle exception for user with no profile and AnonymousUser
                except (Profile.DoesNotExist, AttributeError):
                    pass
                return user
        
        
            # In settings.py:
            CACHED_AUTH_PREPROCESSOR = 'path.to.module.attach_profile'
        
        Running Tests
        -------------
        
        To run the test suite::
        
            python tests/runtests.py
        
        To run the test suite with Django custom user (this will run only on Django 1.5)::
        
            python tests/runtests_custom_user.py
