I've wrote this simple code to test my model:
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="[email protected]", description="desc", url="example.com",
owners=[self.owner.key], training_type=["balance", "stability"], tags=["test", "trento"])
club.put()
in the models the owners is like this owners = ndb.KeyProperty(kind="User", repeated=True)
if i run this code with unittest it works perfectly.
I tried to run it with unitest and nosegae and it fails for a problem with the Key

any idea why?
i run the test from console with this command nosetests tester_ndb.py --with-gae
Could you try running nose with the flag --without-sandbox?
There seems to be an older issue on the former tracker about the same thing.
https://code.google.com/p/nose-gae/issues/detail?id=60
I recently took over maintaining NoseGAE so I will look into the root cause as well but I am assuming it is something internal to the App Engine SDK.
EDIT: --without-sandbox was removed in NoseGAE 0.4.0 when I migrated it to dev_appserver2
