Clear nullable foreign keys on delete
Django 1.0 is apparently hard-coded for cascading deletes. I find that I often have nullable foreign keys on models whose records must not be deleted along with those they refer to. I override Model.delete() in an intermediate base class and execute this method to clear out all nullable foreign keys before allowing a delete to proceed.

- delete
- cascade
