This allows us to efficiently initialise an object from a DB or RPC, reset its changes, then pass to an application handler function. Whatever changes the function makes will be tracked by the object and are available in e.g. obj.obj_what_changed(). If we want to e.g. save the object back to the DB, we only need to save the changed fields.\n\nSo here, I want to model a scenario where the object initially has missing\u003d\u0027something\u0027, then track the changes from that point.","commit_id":"9b36dcf0f2ab79cd9d44e143ca8f9514eaf7b70f"},{"author":{"_account_id":24828,"name":"Kaifeng
