I'm trying to implement a simple mailing list unsubscribe feature. For the model, I currently have an "Unsubscribe" class with a ReferenceProperty to the default User class, and a DateProperty to record the unsubscribe time. A record in this table/instance of this class would indicate that a specific User has unsubscribed.
The problem I've run into is that I don't see any way to take advantage of this model. How would you query all Users who *aren't* referenced by Unsubscribe? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group. To post to this group, send email to [email protected] To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/google-appengine?hl=en -~----------~----~----~----~------~----~------~--~---
