I am also pretty green with GAE, but I think that the db Model Event and the db model event are 2 different db models.
If they are 2 different models this would be why you are always getting none when you read from it. You would be able to see if you have 2 in the console. BTW - What is "None"? I do not see that as a db Model option in the Google doc. It looks to me like you would want those to be strings.
