Django Deprecation Warning or ImproperlyConfigured error - Passing a 3-tuple to django.conf.urls.include() is not supported

As of Django 1.9, the old way of including the admin urls is deprecated. You should pass admin.site.urls directly to url(), without the call to include():

from django.contrib import admin

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    ...
]
