Question

这是我的python类

from app.commons.abstract.dal import ndbService
from google.appengine.ext import ndb
from app.conference.models.conference import ConferenceNDB, ConferenceMessageNDB


conference_key = ndb.Key('Conference', 'CFC Australia')


    class ConferenceService(ndbService):
        def convert_to_object(self, value):
            conf = ConferenceNDB(parent=conference_key)
            conf.name = value['name']
            conf.year = value['year']
            conf.description = value['description']
            return conf

        def write(self, value):
            conference = self.convert_to_object(value)
            return conference.put()

        def read(self, value):
            key = ndb.Key(urlsafe=value)
            conference = key.get()
            return conference

        def remove(self, value):
            pass

这是单元测试

  def test_conference_write(self):
        conf = {'name': 'xxxx',
                'year': 2017,
                'description': 'xxxx'}

        svc_conf = ConferenceService()
        key = svc_conf.write(conf)
        print(key)
        self.assertIsNotNone(key)

我的单元测试失败，出现以下错误。

使用我的测试库中的以下代码修复它

def setUp(self):
    self.testbed = testbed.Testbed()
    self.testbed.setup_env(
        app_id='_',
        overwrite=True
    )
    self.testbed.activate()
    self.testbed.init_datastore_v3_stub()
    self.testbed.init_memcache_stub()
    ndb.get_context().clear_cache()

键包括app_id。你可以通过key.app（）来看到它。

默认的app_id是＆＃39; _＆＃39;。您的conference_key是在导入源文件时使用默认的app_id（＆＃39; _＆＃39;）进行的。

之后，您将app_id设置为＆＃39; testbed-test＆＃39;你应用中的某个地方。然后所有密钥都包含app_id（＆＃39; testbed-test＆＃39;），并且您的密钥不匹配。

因此，在设置app_id后创建密钥。

BadRequestError：app＆＃34; testbed-test＆＃34;无法访问应用＆＃34; _＆＃34;的数据
