I was thinking about this a bit more. As a work around, you could also
add an __init__ to your model. Normally, no __init__ method is needed,
but if you did something like this:
class MyModel(models.Model):
def __init__(self, *args, **kwargs):
super(MyModel, self).__init__(*args, **kwargs)
self.pickled_field = cPickle.dumps(value)
it might do the job without having to modify Django's core. You can just
explicitly convert the field (or fields) to the value you want. It's not
particularly neat as a general solution for field sub-classing, but for
one or two fields with code that works right this minute, it could be
worth trying.
