Change google app engine name

Question

i cloned a working google app engine repo into my local env and got it to work. Later i decided i wanted to deploy to my own GAE app so i changed the name in app.yaml to the one in my newly created app.

But then when launching it with the GoogleAppEngineLauncher i got this error:

BadRequestError: app "dev~bandtasticnews" cannot access app "dev~noticiashacker"'s data

The original name is noticiashacker and the new one is bandtasticnews, the cloned worked alright online but the dev is broken, i have to change the name on app.yaml to the original if i want it to launch locally and return it before deploying.

There are no more lines on my code referencing the original name, i don't know why is it trying to retrieve it.

UPDATE Here is the stack trace shown in the GoogleAppEngineLauncher logs

UPDATE Tried it on a different computer and it was the same thing, but this time i tried to run the app without ever having the name noticiashacker on it.

UPDATE The app.yaml

application: bandtasticnews
version: 5
runtime: python27
api_version: 1
threadsafe: false

libraries:
- name: django
  version: "1.3"

Answer 1

In my case, simply deleting the cookie solves the problem. I found this solution after that I observed that Chrome incognito mode had no problem with it.

Answer 2

Try logging in to admin console,

http://localhost:8888/_ah/admin 

while keeping the original name, you can see some data in datastore viewer, clear it off (for all types of entities), stop the dev-server and change the name to new one, and start again. It should work.

The problem is with namespaces, the way google separates data between multiple applications. Some of your data is persisted with old namespace which is not getting deleted.

Answer 3

Maybe try this, first download your app to a new directory

appcfg.py download_app -A <your_app_id> -V <your_app_version> <output-dir>

Create a new app.yaml with the app id you want to use (don't copy it but create it new) then run dev_appserver ./

good luck

Answer 4

You have data from the old appid in the dev datastore.

You need to clear you local datastore with --clear_datastore when you start the dev server. Not sure how you do that in the Launcher (never use it)
