我正在开发一个开源 django 网络应用程序,我正在寻找使用 Factory Boy 来帮助我为一些测试设置模型,但是在阅读文档和查看示例几个小时后,我认为我需要接受失败并在这里问。
我有一个看起来有点像这样的客户模型:
class Customer(models.Model):
def save(self, *args, **kwargs):
if not self.full_name:
raise ValidationError('The full_name field is required')
super(Customer, self).save(*args, **kwargs)
user = models.OneToOneField(
settings.AUTH_USER_MODEL,
on_delete=models.SET_NULL,
related_name='customer',
null=True
)
created = models.DateTimeField()
created_in_billing_week = models.CharField(max_length=9)
full_name = models.CharField(max_length=255)
nickname = models.CharField(max_length=30)
mobile = models.CharField(max_length=30, default='', blank=True)
gocardless_current_mandate = models.OneToOneField(
BillingGoCardlessMandate,
on_delete=models.SET_NULL,
related_name='in_use_for_customer',
null=True,
)
我还使用来自 django.contrib.auth 的标准 Django 用户模型。
这是我的工厂代码:
class UserFactory(DjangoModelFactory):
class Meta:
model = get_user_model()
class CustomerFactory(DjangoModelFactory):
class Meta:
model = models.Customer
full_name = fake.name()
nickname = factory.LazyAttribute(lambda obj: obj.full_name.split(' ')[0])
created = factory.LazyFunction(timezone.now)
created_in_billing_week = factory.LazyAttribute(lambda obj: str(get_billing_week(obj.created)))
mobile = fake.phone_number()
user = factory.SubFactory(UserFactory, username=nickname,
email="{}@example.com".format(nickname))
就我而言,我希望能够产生这样的客户
CustomerFactory(fullname="Joe Bloggs")
并使用正确的用户名和电子邮件地址生成相应的用户。
现在,我收到此错误:
AttributeError: The parameter full_name is unknown. Evaluated attributes are {'email': '<factory.declarations.LazyAttribute object at 0x111d999e8>@example.com'}, definitions are {'email': '<factory.declarations.LazyAttribute object at 0x111d999e8>@example.com', 'username': <DeclarationWrapper for <factory.declarations.LazyAttribute object at 0x111d999e8>>}.
我认为这是因为我在客户中依赖一个惰性属性,在创建用户工厂之前不会调用它。
如果我希望能够使用工厂来创建 Customer 模型实例,以及如上所述的相应用户,我应该怎么做?
对于它的价值,完整的模型可以在 github repo 上看到
