Comment (by Simon Charette):
Yeah that seems like the correct approach. I was about to suggest
{{{#!diff
diff --git a/django/contrib/contenttypes/fields.py
b/django/contrib/contenttypes/fields.py
index ed98ecb48c..6098b71a39 100644
--- a/django/contrib/contenttypes/fields.py
+++ b/django/contrib/contenttypes/fields.py
@@ -202,7 +202,7 @@ class GenericForeignKey(FieldCacheMixin):
else:
model = self.get_content_type(id=ct_id,
using=obj._state.db).model_class()
- return (model._meta.pk.get_prep_value(getattr(obj,
self.fk_field)),
+ return (model._meta.pk.to_python(getattr(obj,
self.fk_field)),
model)
}}}
But it looks like this is really just an issue with `UUIDField`.
