- authentication anonymous
- 2 (after 4 ratings)
If you want anonymous visitors to your site, or parts of your site to be authenticated as real users so that you can treat them as such in your views and models, use this snippet. Add the above AuthenticationBackendAnonymous middleware into AUTHENTICATION_BACKENDS in your settings.py and use the snippet anonymous_or_real(request) in your views, which returns a user. Comment out the bit where it creates a profile if you are not using profiles.
