Question

我在数据库中有一个喜欢的值，我想在喜欢超过10时更改值STATE。这是我的数据库结构

"QUESTIONS" : {
"ENGLISH" : {
  "QUESTIONID" : 1
},
"SPANISH" : {
  "1" : {
    "ANSWER" : true,
    "LIKES" : 11,
    "MADEBY" : "lScayuKFOrOWyenYYxbL3lJ8Utt1",
    "QUESTION" : "djshsvs",
    "SPAM" : 1,
    "STATE" : "WAITING"
  },
  "2" : {
    "ANSWER" : true,
    "LIKES" : 2,
    "MADEBY" : "lScayuKFOrOWyenYYxbL3lJ8Utt1",
    "QUESTION" : "djdbdb",
    "STATE" : "WAITING"
  },
  "3" : {
    "ANSWER" : true,
    "MADEBY" : "lScayuKFOrOWyenYYxbL3lJ8Utt1",
    "MISPELLED" : 1,
    "QUESTION" : "fhki",
    "STATE" : "WAITING"
  },
  "4" : {
    "ANSWER" : true,
    "LIKES" : 1,
    "MADEBY" : "lScayuKFOrOWyenYYxbL3lJ8Utt1",
    "QUESTION" : "bkkki",
    "STATE" : "WAITING"
  },
  "QUESTIONID" : 4
}

}，

我的火力基地功能

'use strict';

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

exports.newPost = functions.database
.ref('/QUESTIONS/SPANISH/{postID}'/"LIKES")
.onWrite(function(event) {

 const likes=event.data.value;
 const id=event.params.postID;

 if(likes>10){

    return event.data.ref.parent.child('STATE').set("ACEPTED");
 }
 return false;

});

该功能已正确部署，但除非我增加喜欢没有任何反应，我做错了什么？

Answer 1

您的参考字符串看起来不正确。你有这个：

'/QUESTIONS/SPANISH/{postID}'/"LIKES"

不应该是这个吗？

'/QUESTIONS/SPANISH/{postID}/LIKES'

Answer 2

除了更改参考字符串（如上所述）之外，请尝试更改此行：

const likes=event.data.value;

到这一个：

 const likes=event.data.val();

Firebase功能未被调用
