我正在尝试测试一些包括调用 celery 任务的函数。任务涉及调用 3rd 方网站，我需要在测试期间避免它。

知道如何在测试期间禁用所有 celery 任务吗？

当我在我的一个项目应用程序上执行迁移时,我收到以下错误:

ValueError:模型的未处理挂起操作:common.shipmentaddress(由fields:catalog.Fulfillment.address引用)

Django 1.9,python 2.7.10

我一直在寻找循环导入,但我不认为这是它

这些是模型:

class ShipmentAddress(models.Model):
    recipient_first_name = models.CharField(max_length=50, null=True, blank=True)
    recipient_last_name = models.CharField(max_length=50, null=True, blank=True)
    street_name = models.CharField(max_length=50)
    state = models.ForeignKey(State)
    postal_code = models.IntegerField(default=0)
    city = models.CharField(max_length=50)

    class Meta:
        db_table = 'shipment_address'


class Fulfillment(models.Model):
    address = models.ForeignKey(ShipmentAddress)
    inventory_items = models.ManyToManyField(Item_With_Size, through='Inventory_Item')

    class Meta:
        verbose_name = 'fulfilment'
        verbose_name_plural = 'fulfilments'
        db_table = 'fulfilment'

迁移看起来像这样:

class Migration(migrations.Migration):

    dependencies = [
        ('catalog', '0009_auto_20151130_1118'),
     ]

    operations = [
        migrations.AlterField(
            model_name='fulfillment',
            name='address',
            field=models.ForeignKey(on_delete=django.db.models.deletion.CASCADE, to='common.ShipmentAddress'),
        ),
    ]

class Migration(migrations.Migration):

    dependencies = [ …

我有一个带有clean方法的模型,它检查两个字段是否为null,如果是,则引发ValidationError

如何在不使测试失败的情况下执行测试(通常我使用鼻子)来进行实例创建.我想做一些断言以确保实例的创建失败.

这是干净的方法:

def clean(self):
    if not self.message and not self.image:
        raise ValidationError('You must provide either Message and/or '
                              'Image')
