$ ./manage.py migrate
System check identified some issues:

WARNINGS:
?: (1_7.W001) MIDDLEWARE_CLASSES is not set.
	HINT: Django 1.7 changed the global defaults for the MIDDLEWARE_CLASSES. django.contrib.sessions.middleware.SessionMiddleware, django.contrib.auth.middleware.AuthenticationMiddleware, and django.contrib.messages.middleware.MessageMiddleware were removed from the defaults. If your project needs these middleware then you should configure this setting.
