I have my models declared in this way:
class Person(models.Model):
name = models.CharField(max_length=50, unique=True)
class Pet(models.Model):
owner = models.ForeignKey(Person, to_field='name')
name = models.CharField(max_length=30)
def __unicode__(self):
return self.name
I got empty list when trying to get pets from its owner.
>>> person = Person(name='A')
>>> person.save()
>>> pet = Pet(owner=person, name='B')
>>> pet.save()
>>> Pet.objects.filter(owner=person)
[]
>>> Pet.objects.filter(owner__in=Person.objects.all())
[]
It works as expected with explicit id
>>> Pet.objects.filter(owner__id=person.id)
[<Pet: B>]
>>>
Pet.objects.filter(owner__id__in=Person.objects.all().values_list('id',
flat=True))
[<Pet: B>]
Setting owner to the name of the person works also
>>> Pet.objects.filter(owner=person.name)
[<Pet: B>]
I didn't find any document on this, is this a convention, or this is a
bug?
