Clarify .build() issue with Django>1.8 (Ref #198).
From 1.8 onwards, this crashes: >>> a = MyModel() # Don't save >>> b = MyOtherModel(fkey_to_mymodel=a) In turn, it breaks: class MyModelFactory(factory.django.DjangoModelFactory): class Meta: model = MyModel class MyOtherModelFactory(factory.django.DjangoModelFactory): class Meta: model = MyOtherModel fkey_to_mymodel = factory.SubFactory(MyModelFactory) MyOtherModelFactory.build() # Breaks The error message is: Cannot assign "MyModel()": "MyModel" instance isn't saved in the database. See https://code.djangoproject.com/ticket/10811 for details.
