Hi,
Here's my code:
class Country(models.Model):
....
class Organisation(models.Model):
country = models.ForeignKey(Country, db_index=True)
....
Then, in a views, I select a number of organisations:
orgs = Organisation.objects.filter(blabla=something)
Now, I'd like to get the number of countries concerned by those
organisations I've selected. How is that possible?
Although the following code is wrong, is there a similar easy way to
achieve that?
country_count = orgs.country_set.all().distinct().count()
Thanks a lot!
Julien
