Question

有没有办法从子类调用父工厂的方法？

通常的chars = 'abcdefghijklmnopqrstuvwxyz1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ' ps = [p for p in itertools.permutations(chars, 3)] random.shuffle(ps)或super(ThisClass, self)方法不起作用，因为ParentClass.method(self)不是类的实例，而是工厂返回的对象。

self

错误为class SomethingFactory(factory.DjangoModelFactory): # Meta, fields, etc @factory.post_generation def post(self, create, extracted, **kwargs): # Some steps class SomethingElseFactory(SomethingFactory): @factory.post_generation def post(self, create, extracted, **kwargs): super(SomethingElseFactory, self).post(create, extracted, **kwargs)。

（快捷方式TypeError: super(type, obj): obj must be an instance or subtype of type生成相同的错误。）

如何从子类访问父工厂super().post(create, extracted, kwargs)方法？

根据您在基类post()中尝试执行的操作，您可以将其拉出到函数中并从两个位置调用它：

def set_attributes(obj):
    obj.attr1 = True
    obj.attr2 = 1000


class SomethingFactory(factory.DjangoModelFactory):
    # Meta, fields, etc

    @factory.post_generation
    def post(self, create, extracted, **kwargs):
        set_attributes(self)


class SomethingElseFactory(SomethingFactory):

    @factory.post_generation
    def post(self, create, extracted, **kwargs):
        set_attributes(self)
        # Do some other stuff

在没有`self`的~Factory子类中调用factory_boy超类方法
