I am getting the following error on the AppEngine DevServer in Go:
API error 1 (datastore_v3: BAD_REQUEST): ApplicationError: 1 app "id1" cannot access app "id2"'s data
(where "id1" and "id2" are real identifiers used by two of my applications)
I have tried to empty the datastore using the --clear_datastore flag, and also specifying a new path to the datastore using --datastore_path. The latter did not seem to work, no data was stored at the new location. The former flag deleted the contents of the datastore, but whenever I try to upload a blob I get the error.
I am hoping there is something I can do to remedy this!
--EDIT: To clarify, I am not trying to move data across apps, I am merely trying to upload to the active app's blobstore. I am developing several apps at the same time (different companies), so the machine will have several datastores/blobstores. In Java this is not a problem, only in Go.
Also, this is only a problem on the DevServer, once I upload the app, everything works as it should.
Ex animo, /Alexander.
GAE Apps cannot direcly access each other's data. This is a fundamental restriction. DevAppServer is merely preventing you from doing something during development that would be forbidden to a deployed app.
You can move data between apps via url fetching.
