[google-appengine] Re: there may be something wrong with put_async
You should read the docs a bit more. In the intro to async operations it even says In this example, it's a little silly to call future.get_result: the application never *uses* the result from NDB. That code is just in there to make sure that the request handler doesn't exit before the NDB put finishes; if the request handler exits too early, the put might never happen. As a convenience, you can decorate the request handler with@ndb.toplevel. This tells the handler not to exit until its asynchronous requests have finished. This in turn lets you send off the request and not worry about the result. https://developers.google.com/appengine/docs/python/ndb/async On Wednesday, April 9, 2014 11:26:07 PM UTC+8, saintthor wrote: model.put_async() then return. without calling Future.get_result(). shouldn't the model be written to datastore? -- You received this message because you are subscribed to the Google Groups Google App Engine group.
