Not JSON serializable

[brunofin]

I'm using django-uuidfield together with django-rest-framework to develop a RESTful API.
Whenever I try to use the UUIDField, Django throws me this error:

TypeError at (...)
UUID('a00fef915e284f6d9d9af8b0500234b7') is not JSON serializable

I believe the UUIDField lacks a method which can serialize it to JSON using python's JSON encoder and decoder.

Here's the stack trace:

I looked into this a bit more since I was having the same problem and found that this is happening only models where the related model's (the model inside ForeignKey) primary key is a uuidfield.

There is already a pull request that fixes this issue (for me at least) #22 you need to apply this patch to the current PyPi 0.5.0 version, which has unicode fixes not found in this repo.
