[Django]-Getting the primary key of related object with inherited model in Django

You can control the name if you specify a OneToOneField on B with parent_link=True. For example:

class A(TranslatableModel):
    translations = TranslatedFields(
        name = models.CharField(max_length=30)
    )
    f = IntegerField()

class B(A):
    link_back_to_A = OneToOneField(A, parent_link=True) # specify the name
    some_field = ...
