如何使用 NodeJS 更新子文档猫鼬

Question

console.log("check")
 
Email.findOneAndUpdate(
    { _id: req.params.idUser, "sendedEmail.emailId": req.params.idEmail},
    { 
        $set: {
            "sendedEmail.$.isSeen": true
        }
    },
    function(error) {
        if (error) {
            console.log(error);
        }
    }
);

var emailList = await Email.find()

res.send(emailList)

它在本地主机上工作正常，但在 vps 中它不会改变任何东西

修改这一行：var Email = mongoose.model('Email', emailSchema)。 Mongoose 将创建一个名为：'emails' 的集合

const mongoose = require('mongoose');  
var emailSchema = new mongoose.Schema({     subscriberEmail: String,    sendedEmail: Array,     },     {        versionKey: false     } )  
var Email = mongoose.model('Email', emailSchema); 
module.exports = Email;

用 findById() 方法试试这个语法：

updateEmail: (req, res) => {
        let Id = req.params.id;
        Email.findById(Id, (err, res) =>{
            if(err) return res.status(500).send({message: 'Error to find'});        
        }); 

        let update = req.body;
        Email.findByIdAndUpdate(Id, update, {new: true}, (err, EmailUpdated) => {
            if(err) return res.status(500).send({message: 'Error while updating'});
            if(!EmailUpdated) return res.status(404).send({message: 'Email doesnt exist'});
            return res.status(200).send({email: EmailUpdated});
        });
    },
