Let's say I already know the key of an entity in the datastore I want to update and want to update only a single property value inside that entity.
With SQL, you would simply do UPDATE table SET table.a = new_value WHERE key=key_value Is it possible to do the same with the AppEngine datastore? If I simply create a new db.Model instance with the same key and set the new value, calling put on this instance overrides all properties for this entity, not just the one I want to update. Therefore, I currently have to retrieve the existing entity, update the value, and then do the put. This is two datastore operations instead of just one. I'm doing a lot of batch operations using the remote_api, and I'd like to minimize and round-trip times. -- Andrew --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Google App Engine" group.
