Hi.

Django doesn't support composite keys.

Django doesn’t support composite primary key as the ORM heavily relies on a single attribute of a class(e.g: pk or id) field for its inference and usage in the django applications. Owing to this reason composite primary keys are not permitted in Django. But you may use unique_together constraint on the field if that fits your bill.
