如何為Factory Boy指定數據庫？

Question

FactoryBoy似乎總是在默認數據庫中創建實例。 但我有以下問題。

cpses = CanonPerson.objects.filter(persons__vpd=6,
                                   persons__country="United States").using("global")

代碼指向global數據庫。 我還沒有找到在工廠中指定數據庫的方法：

class CanonPersonFactory(django_factory.DjangoModelFactory):
    class Meta:
        model = CanonPerson
        django_get_or_create = ('name_first', 'p_id')
    p_id = 1
    name_first = factory.Sequence(lambda n: "name_first #%s" % n)

    @factory.post_generation
    def persons(self, create, extracted, **kwargs):
        if not create:
            # Simple build, do nothing.
            return

        if extracted:
            # A list of groups were passed in, use them
            for person in extracted:
                self.persons.add(person)

Answer 1

看起來Factory Boy不提供此功能，但您可以輕松地手動添加它：

class CanonPersonFactory(django_factory.DjangoModelFactory):
    class Meta:
        model = CanonPerson
    ...
    @classmethod
    def _get_manager(cls, model_class):
        manager = super(CanonPersonFactory, cls)._get_manager(model_class)
        return manager.using('global')
    ...

Answer 2

現在可以通過在Meta上添加database屬性來直接支持：

class CanonPersonFactory(django_factory.DjangoModelFactory):
    class Meta:
        model = CanonPerson
        database = 'global'

    ...
