this not hard :
from django.db import models
# Create your models here.
class A(models.Model):
""" model A """
name_a = models.CharField(max_length=20)
def __unicode__(self):
return self.name_a
class B(models.Model):
""" Model B"""
keyfield = models.ForeignKey('mymodel.A')
name_b = models.CharField(max_length=20)
def __unicode__(self):
return self.name_b
