I am a python and Django novice so please excuse me if my question is too stupid.
I have 3 models: Regions, Municipalities and Persons. In the admin interface, when editing the Person object, I want to limit the choices for the Municipalities based on the Region choice (e.g. I want to limit the list only to Municipalities that are in the chosen region). Please advice me which is the best way to do that. Here follow my models: class Region(models.Model): region = models.CharField(maxlength=128) def __str__(self): return self.region class Meta: verbose_name = 'Област' verbose_name_plural = 'Области' class Admin: pass class Municipality(models.Model): region = models.ForeignKey(Region) municipality = models.CharField(maxlength=128) def __str__(self): return self.municipality class Meta: verbose_name = 'Община' verbose_name_plural = 'Общини' class Admin: pass class Person(models.Model): PERSON_TYPES = ( ('Да', 'Юридическо лице'), ('Не', 'Физическо лице') ) region = models.ForeignKey(Region, null = True) municipality = models.ForeignKey(Municipality, null = True) name = models.CharField(maxlength=384) type = models.CharField("Юридическо лице", maxlength=8, choices = PERSON_TYPES, default = 'Да', radio_admin = True) dnomer = models.CharField(maxlength=16, blank = True) bulstat = models.CharField('БУЛСТАТ', maxlength=16, blank = True) egn = models.CharField('ЕГН', maxlength=10, blank = True) city = models.CharField(maxlength=64) postcode_p = models.CharField(maxlength=16, blank = True) address_p = models.CharField(maxlength=128, blank = True) phone_p = models.CharField(maxlength=64, blank = True) def __str__(self): return self.name class Meta: verbose_name = 'Юридическо лице' verbose_name_plural = 'Юридически лица' class Admin: pass --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
