django-uuidfield fix to prefetch_related. No idea what else it breaks instead though :|

urls.py

from django.conf.urls import patterns, include, url
from uuidfield import UUIDField

# Fix the bloody UUID field so that we can do prefetching.
UUIDField._old_to_python = UUIDField.to_python
def maybe_fix_to_python(self, value):
    return unicode(UUIDField._old_to_python(self, value=value))
UUIDField.to_python = maybe_fix_to_python
