Doesn't look to be directly possible from the Django's API; but I guess you
could,
class Car(models.Model):
manufacturer = models.CharField(max_length=127)
name = models.CharField(max_length=127)
manufacturer_name = models.CharField(max_length=256, unique=True)
def save(self, *args, **kwargs):
manufacturer_name = "%s_%s" % (self.manufacturer, self.name)
super(Charge, self).save(*args, **kwargs)
