Delete entities from your local google app engine datastore

First you need to shut down any app that is using the datastore. The app holds the file in memory while running and flushes it to disk when it shuts down. This means any writes you do while the app is running will be undone when you shut down the app.

Next, find the datastore file and connect to it using sqlite.

user@host:path$ sqlite3 my-app.sqlite3

I've got no users
To hold me down
To make me fret, or make me frown
I had users
But now I'm free
There are no users on me

Hi-ho the me-ri-o
That's the only way to be
I want the world to know
