I've updated a little models ( OneToOne field is better for your case) Take
a look at
https://docs.djangoproject.com/en/dev/ref/models/fields/
result model is :
class B(models.Model):
""" Model B"""
keyfield = models.OneToOneField('mymodel.A')
name_b = models.CharField(max_length=20)
def __unicode__(self):
return "%s, %s" % (self.name_b, A.objects.get(id=self.id).name_a)
result output :

In [1]: from mymodel.models import A, B
In [2]: A.objects.all()
Out[2]: [<A: object_A>]
In [3]: B.objects.all()
Out[3]: [<B: object_B, object_A>]
I'm not using admin panel . I'm using generic view for better control :-)
Many thanks,
Serge
