This is a little helper for associating an owner to a newly created object, in this case making the assumption that the current user is always the owner. It removes the necessity of adding a custom save hook to your model.

get_current_user comes from this middleware trick to cache the current user:

from django.contrib.auth.models import User

class OwnerField(User):
    def get_internal_type(self):
        return User.__name__
    def pre_save(self, model_instance, add):
        if model_instance.id is None:
            return get_current_user()
        else:
            return getattr(model_instance, self.attname)
