I ran into a problem with running unit tests against views where it
said that:
HINT: Truncate table "challenges_challenge_attachments" at the same
time, or use TRUNCATE ... CASCADE.
I patched it to be this, only for postgresql. This patch seems to work
quite well. I don't know if there are any pitfalls but this allowed me
to create my own views using the unmanaged model and still test
successfully with foreign keys.
Thanks,
~Ben
