You have a typo, change the line:
class UserInformation(ndb.model):
to (notice the capital M
):
class UserInformation(ndb.Model):
and it should work fine.

I am new to GAE and Python and I am working through the tutorials google provide, however the problem comes when I try and create more than 1 model class in the same file. If I add something like this:
class Greeting(ndb.Model):
"""Models an individual Guestbook entry with author, content, and date."""
author = ndb.UserProperty()
content = ndb.StringProperty(indexed=False)
email = ndb.StringProperty()
date = ndb.DateTimeProperty(auto_now_add=True)
colours = ndb.StringProperty(repeated=True)
class UserInformation(ndb.model):
username = ndb.UserProperty()
firstname = ndb.StringProperty(required=True)
lastname = ndb.StringProperty(required=True)
telephone = ndb.IntegerProperty()
I get the following error message
Traceback (most recent call last):
File "C:\Program Files (x86)\Google\google_appengine\google\appengine\runtime\wsgi.py", line 239, in Handle
handler = _config_handle.add_wsgi_middleware(self._LoadHandler())
File "C:\Program Files (x86)\Google\google_appengine\google\appengine\runtime\wsgi.py", line 298, in _LoadHandler
handler, path, err = LoadObject(self._handler)
File "C:\Program Files (x86)\Google\google_appengine\google\appengine\runtime\wsgi.py", line 84, in LoadObject
obj = __import__(path[0])
File "C:\Python27\gae\listproperty\main.py", line 37, in <module>
class UserInformation(ndb.model):
TypeError: Error when calling the metaclass bases
module.__init__() takes at most 2 arguments (3 given)
If I put the UserInformation class into a second file and try and import it into main.py I get a similar error message again.
My question is what is the best way to handle multiple ndb.model class in GAE using Python?
Any help would be appreciated
