This is a post covering my first time experience with integrating Persona authentication into my Django project named richard. I briefly cover why I did it, what I used, and list the commits I did the work in as an example of how it can be done. I hope this helps others implement it on their sites..
A month ago, I added Persona authentication support to richard. This allowed me to use Persona authentication for pyvideo.org. I did this for several reasons:
I wanted to try it out and see how well it worked on a small Django site (tl;dr works great---I'll use this on all my sites)
I wanted people to authenticate with an email-based identity rather than a social network based identity
I wanted to allow people to create accounts on pyvideo.org, but didn't want to deal with the responsibility of protecting things like passwords
So that's where I'm coming from.
It took about 15 minutes to get it working. I've made some minor edits to the code since then and updated to v0.8 of django-browserid. All told, I think I've spent a couple of hours on Persona implementation.
In the process of doing that work, I hit a few minor issues, created some pull requests, helped with other pull requests and became one of the maintainers. Yay!
Here are the commits I did the work in. I figured the diffs might help you implement similar things on your sites:
Add persona authentication: https://github.com/willkg/richard/commit/f917409
Update django-browserid to 0.8: https://github.com/willkg/richard/commit/a69a74f
Update to master tip to fix login failure problem I had: https://github.com/willkg/richard/commit/be73b43
That last commit updates to django-browserid master tip to pick up a
fix to login failures if
BROWSERID_CREATE_USER is False. That fix
will be released in v0.8.1 soon.
The Mozilla Persona site helps understand why it exists and has a Developer FAQ.
The django-browserid docs are pretty good and walk through setting it up, advanced usage, and troubleshooting. I encourage you to read through them in full---it'll give you a better understanding of the pieces.
Dan Callahan did a talk at PyCon US 2013 on Persona. That's worth watching. It covers why Mozilla built it, how it works, and why it's important that it works that way. He also demos integrating it into sites and talks about using Persona authentication alongside other authentication methods.
If you're interested in adding Persona authentication to your Django site and need help, let me know.
