I finally put this in its own package! Check out django-jsonview.

This is a decorator that guarantees a response will be JSON, and sends meaningful (to a developer) error messages. It relies on a BadRequest exception I created elsewhere, because there is no standard way of handling that in Django (frex, we should really return HTTP 400 on form validation failures but they don't make that particularly easy). That could easily be removed, though.
