根据查询更新Cloud Firestore中的文档 [英] Updating documents in Cloud Firestore based on a query

问题描述

是否可以使用包含where子句的firebase cloud函数设置值?

is it possible to set values with firebase cloud function that includes a where clause?

例如

admin.firebase.firestore().collection('Accounts').where("imagePathName", '==', docNamed).set({
  original: 'trial'
});

这给我一个错误.

推荐答案

您可以调用

You can call set() to create or update a document represented by a DocumentReference type object.

查询没有set方法.相反，您必须使用从查询中获取所有文档. get()获取 QuerySnapshot ，然后进行迭代，然后分别在每个文档上调用set().

A query doesn't have a set method. You would instead have to obtain all the documents from the Query using get() to obtain a QuerySnapshot, iterate that, then call set() on each document individually.
