Question

我是NodeJS和MongoDB的新手，在创建示例应用时遇到了以下问题

// ************  this is  testusers.js file  ************//

var userdetails = require('userdetails');
var mongoose = require('mongoose');
var schema = mongoose.Schema;

var geekDetails = new schema({
    description: String,
    details: {
        type: mongoose.Schema.Types.ObjectId,
        ref: 'userDetails'
    }
});
module.exports = {
    model: mongoose.model('geekDetails',geekDetails),
    schema: geekDetails
};


// ************  this is  user.js file  ************//

var mongoose = require('mongoose');
var schema = mongoose.Schema;
var userDetails = new schema({
    firstName: String,
    lastName: String,
    email: String,
    password: String
});

module.exports = {
    model: mongoose.model('userDetails',userDetails),
    schema: userDetails
};


// ************  this is  create.js file [used to save the details to DB]  *******//

var testusers = require('testusers.js');
var mongoose = require('mongoose');

adduser = function(firstName,lastName,email,password,passwordConfirmation,description,callback){

    new testusers.model({
        description: description,
        details: {
            firstName: firstName,
            lastName: lastName,
            email: email,
            password: password
        }
    }).save(function(err,result){
        if (err){
            callback(err,null);
        }
        else {
            callback(null,result);
        }
    });

当我尝试保存详细信息时，它返回了以下错误“强制转换为objectid，路径'详细信息'中的值对象对象失败了”我确信我在使用模式做错了但我不能弄明白了。

提前致谢

像这样保存参考文档不会以这种方式使用mongoose。这是另一种选择。实际上，您需要先保存嵌入的文档（userdetails）并使用id保存父级（testuser）。

adduser= function(firstName,lastName,email,password,passwordConfirmation,
    description,callback){

    new userDetails.model({
        firstName:firstName,
        lastName:lastName,
        email:email,
        password:password
    }).save(function(err,doc){
        new testusers.model({
            description:description,
            details: doc._id
        }).save(function(err,result){
            if(err){callback(err,null);}
            else{callback(null,result);}
        });
    });
}

使用promises可以使这段代码更好阅读，但这应该可以提供这个想法。

对于路径mongoose中的值对象对象，转换为objectid失败
