[英]findOneAndUpdate fails using MEAN stack
這是我在我的layout.handlebars上的代碼
$(document).ready(function(){
var socket = io();
// //understand button
$(".understandbtn").click(function(){
//reset the timer every 3 second of interval
$('.actionBtnFloat').css('z-index','0');
//e_money
var deduct = 100;
var newMoney = {{user.e_money}} - deduct;
// send a message to the server that the e-money value has changed
//get the current user
socket.emit('update e-money',getUserName(), newMoney);
// console.log("Emitting the data to the server side - emoney" + getUserName() + "with the name money of :" + newMoney);
//end
clearTimeout(interval);
//send the data to the server
socket.emit('chat message', getUser());
var interval = setTimeout(function(){
$('.'+getUser()).fadeIn();
},5000);
});
socket.on('update e-money response', function (data) {
alert("Your money is: "+ data.newMoney);
console.log("Your money is:" + data.newMoney);
});
socket.on('update e-money error', function (err,data) {
if(err) throw err;
// alert("Could not update your money: "+ data.error);
// console.log("Could not update your money"+ data.error);
alert("Sucessfully updated your money");
console.log("Sucessfully updated your money");
});
在我的服務器上,這是我更新記錄的方式,但是由於錯誤而無法正常工作嗎?
//emoney
socket.on('update e-money', function (data) {
var userName = data.username;
var newMoney = data.newMoney;
var query = {username: userName};
// update the entry on the database
User.findOneAndUpdate(query, { e_money: newMoney }, { upsert: true, new: true }, function (err, doc) {
if (err) {
io.emit('update e-money error', { error: err });
console.log(err);
} else {
io.emit('update e-money response', { e_money: newMoney });
console.log(newMoney);
}
});
});
//end emoney
現在它說無法更新我的記錄,是因為我沒有使用_id嗎?
這是我的錯誤
消息:“在路徑“ e_money”處,值“ undefined”的數字轉換失敗,名稱:“ CastError”,字符串值:““ undefined””,種類:“數字”,值:undefined,路徑:“ e_money”,原因:未定義}
通過這樣做達到了我想要的
User.findOneAndUpdate({"username":userName},
{"$set":{"e_money": newMoney }}, { upsert: true, returnOriginal:false },
function (err, doc) {
