Django model inheritence

Question

Consider we have a model like this

class A(Models.model): .... class B(A): .... x = models.ForeignKey(B, related_name="rn1") .... class C(A): .... x = models.ForeignKey(B, related_name="rn2") ....

Observe that both fields above define the same thing with just a difference in the related_name. I feel that this part can also be shifted to class A somehow and just change the related_name in children.

Can this be done or should I use copies of the same code with different related_name?

If it were ManyToManyField then your thought might work, but since it is a ForeignKey, it is a 1:n relation, and the reverse would not work the same way. — karthikr

Nope.

models.ForeignKey() creates a new object from Foreign key class.

Maybe u can do something in init but this causes more code block and some third party tools like south may give error.
