Description

On this many-to-one self relation example parent needs to have blank=True or else forms won't validate in admin when trying to create a root-level category. 

from django.db import models

class Category(models.Model):
    name = models.CharField(max_length=20)
    parent = models.ForeignKey('self', null=True, blank=True, related_name='child_set')

    def __unicode__(self):
        return self.name
