谷歌应用引擎：unitest works nosetest 失败

Question

我编写了这个简单的代码来测试我的模型：

class NDBTestCase(unittest.TestCase):
    def setUp(self):
        logging.getLogger().setLevel(logging.INFO)
        # First, create an instance of the Testbed class.
        self.testbed = testbed.Testbed()
        # Then activate the testbed, which prepares the service stubs for use.
        self.testbed.activate()
        # Next, declare which service stubs you want to use.
        self.testbed.init_datastore_v3_stub()
        self.testbed.init_memcache_stub()
        self.owner = m_User(username="owner")
        self.owner.put()


    def tearDown(self):
        self.testbed.deactivate()


    def testClub(self):
        # this id is a manually assigned
        club = m_Club(id="1", name="test", email="test@test.com", description="desc", url="example.com",
                      owners=[self.owner.key], training_type=["balance", "stability"], tags=["test", "trento"])
        club.put()

在模型中owners 是这样的owners = ndb.KeyProperty(kind="User", repeated=True)

如果我使用 unittest 运行此代码，它会完美运行。 我尝试使用unitest 和nosegae 运行它，但由于Key 的问题而失败

BadValueError: Expected Key, got Key('User', 1)

知道为什么吗？ 我使用此命令从控制台运行测试nosetests tester_ndb.py --with-gae

Answer 1

你能不能用--without-sandbox的旗子流鼻涕？

以前的跟踪器上似乎有一个关于同一件事的旧问题。

https://code.google.com/p/nose-gae/issues/detail?id=60

我最近接管了 NoseGAE 的维护工作，因此我也会调查根本原因，但我假设这是 App Engine SDK 内部的问题。

编辑：当我将 --without-sandbox 迁移到 dev_appserver2 时，在 NoseGAE 0.4.0 中删除了它

Answer 2

我也遇到过类似的奇怪错误。我认为谷歌代码中的某个地方存在错误。我通过调整我的代码以稍微不同的方式做同样的事情来解决它。

尝试改变

self.owner.put()

到

ndb.put(self.owner)
