[google-appengine] Re: Can not update db
i solved. it is so strange. code as yours do not work till i alter it to: dests = db.GqlQuery( SELECT * FROM Dj_User WHERE UserID = '4' ) dests.get() d = dests[0] d.UserName = aaa db.put( d ) it won't work without using the d. i think it is a bug. thank you for helping.

It's a bug in your earlier code. db.put(dests) is a lot different than db.put(d) when d == dests[0]; dests != dests[0] --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Google App Engine group.
