I'm trying to get a Tastypie login system to work, however when I send a json request with the user data, the server responds with Http 500. I have looked through all of my code and tried to debug the issue but nothing I try is working.

I've looked around and can't find anything to help me.

Does anyone know how I can go about fixing this issue or if there is something I should be doing that I am not.

Thanks.
