Firstly, you need to add another method -- this time to the model itself:: class Person(models.Model): - objects = PersonManager() - first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) - birthdate = models.DateField() - def natural_key(self): - return (self.first_name, self.last_name) + objects = PersonManager() class Meta: unique_together = (('first_name', 'last_name'),) + def natural_key(self): + return (self.first_name, self.last_name) + That method should always return a natural key tuple -- in this example, ``(first name, last name)``.
