[Answer]-Managing X-HTTP-Method-Override with tastypie in Heroku?

The 501 error has nothing to do with Heroku.

I believe it to be the setup of your Resource.

There is a bit of a gotcha with TastyPie, and I would refer to the following line from the documentation:

“For PATCH to work, you must have put in your detail_allowed_methods setting.”

i.e.

detail_allowed_methods = [‘get’, ‘post’, ‘put’, ‘delete’, ‘patch’]
