I want to implement Facebook connect login for my Django site and I've checked the already existing apps.
So far, I have found Django-Socialauth, django-socialregistration, and django-facebookconnect for this purpose.
The question is which one to choose, and I would like to hear from other developers who have experience with any of these apps.
It is important for me that the Facebook Connect login app plays nicely with @login_required, with the default auth system, and with django-registration.
Please share your experience :)
Update (11/26/2013): I'm updating my recommendation. Since a sufficient amount of time has passed since I wrote this answer, I would recommend python-social-auth or django-allauth as the best tools for the job. They are active projects with good documentation and support for a lot more than just Facebook. I've had success using both.
I have had the most luck with adapting django-socialregistration with django-registration (0.8). Since you're working with django-registration, you're going to have to do a little bit of work, since all three of those packages assume the role of both the creation and the authentication of the user.
I was just going to explain what needed to be done, but you inspired me to finally get my version out: hello-social-registration.
Like I alluded to, it separates gives the registration functions to a django-registration backend and handles all the authorization itself. I've been using this on my near-beta application for a while now with no problems (I also handed it to a friend to use a few months ago and he got it to work without much modification).
It's definitely not ready to be a plug-and-play reusable application, yet, but hopefully it'll provide you with some insight. :)
