Clean datastore for GoogleAppEngine

Question

How to clear datastore in GoogleAppEngine.

I want to clear my development data to do a test again, but I can found a way to do that

Answer 1

If you are running from the commandline, use the --clear_datastore flag, e.g.,

dev_appserver.py --clear_datastore=yes app

Otherwise, if you're running it off the included GAE launcher, go into the settings of your app (double click it), and there should be a little checkbox that says "clear datastore on launch" under Launch Settings.

Answer 2

dev_appserver.py --clear_datastore myapp 

assuming by "development data", you mean the data in the dev server.
