Hi, I have two simple models:
class Country(models.Model): name = models.CharField(_("Name"), max_length=50, unique=True) class Profile(models.Model): name = models.CharField(_("Name"), max_length=50, unique=True) country = models.ForeignKey(Country) If I want to create a list of all countries that are actually referenced (i.e. used by at least one Profile entry), how would I code that in Django? Maybe something like (of course this is rubbush): referenced_countries = Country.objects.exclude (profile__country__isnull=True) Thanks for your help Markus --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
