class Category(models.Model):
name = models.CharField(maxlength=70)
parent = models.ForeignKey('self', blank=True, null=True,
limit_choices_to = {'parent__isnull': True})
I dont want to be able to select a parent which is actualy the
category currently edited.
I tried a custom validator but I dont have access to the category_id.
So I tried a custom manipulator but I couldn't fix it to work in admin
The only possible solution I have now is the raise an error in the
custom save method, which is a terrible ugly solution.
Does anyone have a pointer to a simple method to extend the automatic
manipulator???
Thanks,
Rob
