Factoryboy 在使用子工厂时返回错误的字段

Question

I have a table FilmWork which is linked to a table Perosn via FilmWorkPerson table. I am trying to populate them with fake data

I have basically used this example: https://factoryboy.readthedocs.io/en/rbarrois-guide/recipes.html#many-to-many-relation-with-a-through

factories.py:

  class PersonTestFactory(DjangoModelFactory):
    class Meta:
        model = Person

    id = factory.Faker('uuid4')
    name = factory.Faker("sentence", nb_words=1)

 class FilmWorkTestFactory(DjangoModelFactory):
    class Meta:
        model = FilmWork

    id = factory.Faker('uuid4')
    title = factory.Faker("company")

 class FilmWorkPersoTestFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = FilmWorkPerson

    movie_id = factory.SubFactory(FilmWorkTestFactory)
    person_id = factory.SubFactory(PersonTestFactory)

class FilmWorkPersoTestFactory2(FilmWorkTestFactory):
    membership = factory.RelatedFactory(
        FilmWorkPersoTestFactory,
        factory_related_name='movie_id',
    )

But when I call FilmWorkPersoTestFactory2() , it returns an error: ['“Fisher, Smith and Ford” is not a valid UUID.'] . I think it takes title instead of id and I do not understand how to point it to the correct field.
