Hey everyone,

I've asked a little in the Django IRC, but nobody seems to be able to
help. I'm trying to implement a custom model field, and I really can't
figure out why I keep getting errors. My code for my fields module is
at http://dpaste.com/hold/27712/

When I try to run syncdb on a model which uses the PickledObjectField
(see my sample model at http://dpaste.com/hold/27713/), I get this
traceback:-

Macintosh:sandbox Oliver$ cd /Django/sandbox && python manage.py

Can anyone point me in the right direction?

Thanks so much,
Oliver
