Hello everyone, I recently posted a question on stackoverflow.com http://stackoverflow.com/questions/10623854/django-soft-foreignfield-without-database-integrity-checks
*I have a Django project that has multiple django "apps". One of them has > models to represent data coming from an external source (I do not control > this data). > **I want my other apps to be able to have references to this "external > app" but I want to avoid all the fuzz of the database integrity checks. I > don't want the db to have any constraints on these "soft foreign keys". > **Do you know how I can code a custom field that will emulate a real > Django ForeignKey without creating a hard constraint on the database? > **Maybe this already exists, but I didn't have any luck on Google. > **Thanks in advance for the help :-) > **NB: I'm aware of the generic > relations<https://docs.djangoproject.com/en/1.4/ref/contrib/contenttypes/#generic-relations> > system > with the content_types. But I don't want generic relations.

I've looked deep into django's code to find what needs to be done, but I think that simply subclassing ForeignKey will not be enough. Could you give me some directions on how to do this? NB: I use South for managing my database schema, so I figure I'll need to do something about that too. But it may be out of the subject here :) Thanks in advance for the help!
