Modern Django (2017+?) has a setting called LOGOUT_REDIRECT_URL.

You don’t need to overwrite or wrap anything.

According to the docs, you can just supply the next_page argument to the logout view.
https://docs.djangoproject.com/en/dev/topics/auth/default/#django.contrib.auth.views.logout

(r'^logout/$', 'django.contrib.auth.views.logout',
                          {'next_page': '/successfully_logged_out/'})
