Hi, list I'd like to share my trial implementation of transaction between entities in different entity groups. I will be glad if you can discuss about this implementation freely. This implementation is basically inspired by this thread: http://groups.google.com/group/google-appengine/browse_thread/thread/ba1c22ffffb37581/6e92b0d15b5cb587
main.py: http://pastebin.com/m5aef20b5 This script works with following app.yaml. ---- app.yaml ---- application: tm-test version: 1 runtime: python api_version: 1 handlers: - url: /.* script: main.py ---- app.yaml ---- This script indicates how a particular amount of money/points/etc can move from User A to User B in transaction manner. As a notice, this script itself is not perfect. To make this work correctly, we need cron job or something like that to take care of incomplete transactions. Any comments, thoughts, ideas, all of those are welcome. I hope someone can make this implementation more sophisticated.
