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:
http://code.djangoproject.com/wiki/CookBookThreadlocalsAndUser
1 2 3 4 5 6 7 8 9 10 | 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)
