英文:
Push value in array of mongodb document
问题
你可以使用以下代码来正确更新记录：
module.exports.createroom = async (req, res) => {const { roomid, email } = req.body;UserModel.updateOne({ email: email },{$push: { rooms: roomid }})res.send('done');}
这段代码会将指定的 roomid 添加到具有特定邮箱地址 email 的文档的 rooms 数组中。
英文:
i have one mongodb collection which have documents like these
now I want to push a value to rooms array of a document where email is abc@123.com ....
I have made this controller in node js.
module.exports.createroom = async (req,res) => {const {roomid,email} = req.body;UserModel.updateOne({ email: email },{$push: { rooms: roomid}})res.send('done')}
user schema
const mongoose = require("mongoose")const userSchema = new mongoose.Schema({email:{type:String,require:true},password:{type:String,require:true},rooms:{type:Array}})module.exports = mongoose.model("User",userSchema);
correct syntax for updating the record.

对你的控制器进行更改...
module.exports.createroom = async (req, res) => {const { roomid, email } = req.body;const user = await UserModel.findOneAndUpdate({ email: email },{ $push: { rooms: roomid } },);res.send("done");}
英文:
Make changes in your controller..
module.exports.createroom = async (req,res) => {const {roomid,email} = req.body;const user = await UserModel.findOneAndUpdate({ email : email },{ $push: { rooms: roomid } },)res.send("done")}
