Generic Foreign Keys and get_or_create in django 1.0: Broken?

Question

As you can see, create() works, but get_or_create() doesn't. Am I missing something obvious here?

In [7]: f = FeedItem.objects.create(source=u, dest=q, type="greata")

In [8]: f, created = FeedItem.objects.get_or_create(source=u, dest=q, type="greata")

FieldError: Cannot resolve keyword 'source' into field. Choices are: dest_content_type, dest_object_id, id, src_content_type, src_object_id, timestamp, type, weight

Answer 1

Look like there's different logic used in create and get_or_create as in get_or_create there is no source argument but src_object_id and src_content_type but it is easy to resolve this - pass scr_object_id as u.id and src_content_type as u.content_type (same with dest).

Or use try/except & create.
