Firstly, your foreign keys to Fields won't work because you can't have
foreign keys to tables that don't exist in the database. Abstract
models are meant to be extended from their classes (i.e. class A
(Fields))
Given your Fields abstract class above, here's one way to define A and
B:
class A(Fields):
pass
class B(Fields):
anotherfieldA = models.IntegerField()
anotherfieldB = models.IntegerField()
