The UsersSettings.gql() returns a Query object not a UsersSettings object.
If you know there is only 1 object that matches the query you can call
the get() method of
the Query result.
result = UsersSettings.gql("WHERE owner=:1",
users.get_current_user().nickname()).get()
if result is None:
result = UsersSettings()
You statements
> result.title = title
> result.owner = users.get_current_user().nickname()
just add some instance members to the Query object and not the
UsersSettings objects that the query returns, thats why you don't see
an update, you just put the original UsersSettings object(s) back with
the statement
> db.put(result)
