I don't know, it is not something I've ever needed.  If you Google
"composite primary keys" and Django you'll get hits that point to the ticket
where the feature is requested and various conversations on the development
list, etc.  Perhaps you can find some useful hints in those sources.

No, you cannot do this at present.  Composite primary keys may be supported
at some point, but they are not now.

Re: models created from database table

[Waruna de Silva]

Thanks Ramior for info

In Models is it possible to name to Fields as primary keys

as exmaple, there are two fields
gid = models.IntegerField()
business_id = models.ForeignKey(Business)

how to make both of them as primary keys , following isn't work
gid = models.IntegerField(primary_key=True)
business_id = models.ForeignKey(Business, primary_key=True)

regards,
Waruna
