How to delete all entities for NDB Model in Google App Engine for python?

Question

I have a ndb model class:

class Game(ndb.Model):
    gameID = ndb.IntegerProperty()
    gameName = ndb.StringProperty()

Is there any way to quickly just delete all entities thats stored in the database for this class? Something like Game.deletAll()

No, but you could easily do this with something like:

from google.appengine.ext import ndb

ndb.delete_multi(
    Game.query().fetch(keys_only=True)
)

your `query` is a list of keys: ndb.delete_multi(query) – Gianni Di Noia Sep 22 '13 at 22:27

You'll be a little bit better if you use `iter` instead of `fetch` – Uri London Nov 05 '13 at 17:11
