Firebase Firestore增量FieldValue不增量 [英] Firebase Firestore Increment FieldValue does not increment

问题描述

因此，我已经阅读了所有文档，有关在Firestore数据库中增加计数器的所有内容. 我有此代码

so i've read all the documentation everything about increment a counter in a Firestore database. I have this code

const admin = require("firebase-admin");
const db = admin.firestore();
...
db
.collection("settings")
.doc("totalUsers")
.set({
count: firebase.firestore.FieldValue.increment(1),
});

我只是根本不增加计数器.没有错误，没有日志，什么都没有. 在我的Firestore中，我有一个settings的集合和一个具有属性count的文档totalUsers，该属性是数字类型，等于1.

And i just doesn't increment the counter at all. No errors no logs no nothing. In my Firestore i have a collection of settings and a document totalUsers with a property count that is a number type and it equals to 1.

我做错什么了吗? 我有什么想念的吗? 任何帮助表示赞赏！

Am I doing something wrong? Am I missing anything? Any help appreciated!

推荐答案

对于任何对此有疑问的人，请小心使用.update()方法代替.set().另外，您还需要在Firestore中存在一个值，以便它可以增加一些值.

For anyone having issues with this, be careful to use the .update() method instead .set(). Also you need to have a value existing in the firestore that so it has something to increment.
