Personally, I'd keep the ForeignKey relationship, but just override
Teacher.delete() so that removes itself from all of its Students
before being deleted. Something like this should do it:
class Teacher(models.Model):
# ... Fields here
def delete(self):
for student in self.student_set.all():
student.teacher = None
student.save()
super(Teacher, self).delete()
This, of course, assumes that you created your students include a
field looking something like this:
teacher = ForeignKey(Teacher, null=True)
Would that work for you?
