如何在Google App Engine中为Python删除NDB模型的所有实体?
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()
有什么办法可以快速删除存储在数据库中的这个类的所有实体?例如 Game.deletAll()
Is there any way to quickly just delete all entities thats stored in the database for this class? Something like Game.deletAll()
答
不,但您可以轻松做到这一点:
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)
)
