I quite often reference foreign keys of foreign keys of foreign

Wouldn't it be nice to have a 'through'-parameter for ForeignKey's?
class A(Model):
b = ForeignKey('B')
c = ForeignKey('C', through='B', related_name='a_set')
class B(Model):
c = ForeignKey('C')
i'd love such a feature too, but i think a better syntax could be
something like:
class A(Model):
b = ForeignKey('B')
c = ForeignKey('B__c', related_name='a_set')
class B(Model):
c = ForeignKey('C')
where the second part of the reference is the name of the field ('c'
in this example), not the model class ('C')
On first sight, I think I agree with you that the syntax is cleaner
like this, but I would choose for the through-parameter because it's
more consistent with the use of the through-parameter for
ManyToManyField.
