Comment (by Alex):
I think Anssii, is correct that the right solution is to support "virtual
fields" (and with the multi column primary keys), and have that work with
foreign keys. However, there could be an argument made that ForeignKey
needs some support of its own, specifically with the `to_field` otpion,
which lets you point a foreign key at something besides a primary key,
it's not unreasonable to say that `to_field` should accept a list of
fields. I suspect however that doing this correctly would still require
most of the work of #373, so it should happen afterwards.
