如何在 Google App Engine for python 中删除 NDB 模型的所有实体? [英] How to delete all entities for NDB Model in Google App Engine for python?

问题描述

我有一个 ndb 模型类:

I have a ndb model class:

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

有什么方法可以快速删除存储在该类的数据库中的所有实体?类似于 Game.deletAll()

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

推荐答案

不，但你可以很容易地做到这一点，如:

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)
)
