Tastypie documentation generation
You might want to take a look at tastypie-swagger, which uses Swagger to generate a /doc/ page for your Tastypie API.
I've had some success with it, after a few minor adaptations (which were necessary due to a tastypie version difference, I suppose).
Edit: The adaptations I found necessary (due to a django version < 1.4 and tastypie version > 0.9.11) are now merged into the mainline branch of tastypie-swagger.
There's also Django Tasty Docs which is part of Tasty Tools
