Do you mean that you want Car to have a country_of_origin model.Field (IOW: the yourapp_car table to have a country_of_origin column) and copy the related Producer.country_of_origin field's value in it, or just Car instances to have a "country_of_origin" attribute that is just a shortcut for self.producer.country_of_origin ? > class CarProducer(models.Model): > country_of_origin = models.CharField(max_length=200) > > class Car(models.Model): > producer = models.ForeignKey(CarProducer) > country_of_origin = producer.country_of_origin -- You received this message because you are subscribed to the Google Groups "Django users" group.
