代码：类 StockFactory(UniqueObjectsFactory): FACTORY_FOR = Stock FACTORY_DJANGO_GET_OR_CREATE = ('name', 'market')

market = factory.SubFactory(MarketFactory)
symbol = FuzzyAttribute(lambda: ''.join(random.choice(string.ascii_uppercase) for _ in xrange(4)))
name = FuzzyCompanyName()
# last_trade_price = fuzzy.FuzzyDecimal(0.0, 10000.0)


class PositionsFactory(FreezeableFactory):
    FACTORY_FOR = Position
    FACTORY_DJANGO_GET_OR_CREATE = ('stock','AnotherObject')

    id = FuzzyInteger(100000)
    stock = factory.SubFactory(Stock)

    AnotherObject = factory.SubFactory(AnotherObject)  #If I comment stock out it would fail here

    created_date = FuzzyDateTime(start_dt=datetime(2013, 1, 1, tzinfo=compat.UTC))

错误：

有什么线索吗？想法？我经常和工厂男孩一起工作，而且大多数时候它是一个很好的工具。但经过数小时的调试，我就是找不到问题

我太愚蠢了：那些行是错误的：

stock = factory.SubFactory(Stock)
AnotherObject = factory.SubFactory(AnotherObject)

本来应该：

stock = factory.SubFactory(StockFactory)
AnotherObject = factory.SubFactory(AnotherObjectFactory)

希望它可以帮助遇到此问题的其他人
