What am I doing wrong?
Is there any other way to do what I want?
I'm basically trying to implement the GOF's strategy design pattern
(the real code is more complicated than this example).
## my models
class Donkey(models.Model):
name = models.CharField(max_length=11)
class Barn( models.Model):
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()
animal = generic.GenericForeignKey('content_type', 'object_id')
##my test
def test_barn(self):
donkey = Donkey( name = "Stewart")
donkey.save()
barn = Barn(animal = donkey)
barn.save()
self.assertEqual( barn.animal.name, "Stewart")
donkey.name = "Bob"
donkey.save()
self.assertEqual( len(Donkey.objects.all()),1)
self.assertEqual( Donkey.objects.all()[0].name, "Bob")
self.assertEqual( barn.animal.name, "Bob")
#this fails saying: AssertionError: u'Stewart' != 'Bob'
