在FactoryBoy中定义ModelFactory时,我需要访问SubFactory创建的另一个模型的属性,并将其分配给此ModelFactory的属性。
这就是我想要做的事情:
import factory
class MyModelFactory(factory.DjangoModelFactory):
FACTORY_FOR = MyModel
created_by = factory.SubFactory(AdminUserFactory)**.id**
显然这不起作用,因为没有AdminUser对象来访问MyModelFactory类定义中的id。
这就是我所做的,但它很难看:
import factory
class MyModelFactory(factory.DjangoModelFactory):
FACTORY_FOR = MyModel
dummy_created_by = factory.SubFactory(AdminUserFactory)
created_by = factory.LazyAttribute(lambda o: o.dummy_created_by.id)
@classmethod
def _create(cls, target_class, *args, **kwargs):
del kwargs['dummy_created_by']
return super(MyModelFactory, cls)._created(
target_class, *args, **kwargs)
我试图通读Factory_Boy docs,但没有看到允许我懒惰地访问该属性的类或函数。有没有人有任何建议?

从factoryboy 2.4.0开始,您可以使用exclude。这使您可以向工厂添加一个不会传递到模型类的参数
import factory
class MyModelFactory(factory.DjangoModelFactory):
created_by = factory.SubFactory(AdminUserFactory)
created_by_id = factory.LazyAttribute(lambda o: o.created_by.id)
class Meta:
model = MyModel
exclude = ['created_by']
我已经将OP示例转换为使用created_by_id
,但是您可以对其进行重命名以使其对您有意义。

class MyModelFactory(factory.django.DjangoModelFactory):
FACTORY_FOR = MyModel
dummy_created_by = factory.SubFactory(AdminUserFactory)
created_by = factory.SelfAttribute('dummy_created_by.id')

尝试使用Mixer:
from mixer.backend.django import mixer
mixer.blend(MyModel, created_by=lambda: mixer.blend(AdminUser).id)
