Hi,

I have a foreign key from MyModel to contrib.auth.models.User which can
be null.

Unfortunately if you delete the user, the MyModel instance gets deleted, too.

I found an open ticket[1], but nevertheless don't know how to get the "on 
delete set null"
done.

One solution would be this: subclass User and override delete() and use this 
class for
as foreign key.
But I would prefer a different solution.
