在猫鼬中，如何启动具有其他模型参考的模型

Question

下面有一个名为User的模型。

var mongoose = require('mongoose');<br> var Schema = mongoose.Schema;

var User = new Schema({<br>
        firstName : {type: String, unique: false},<br>
        lastName : {type: String, unique: false},<br>
        loginName : {type: String, unique: true},<br>
        password : {type: String, unique: false},<br>
        email : {type: String, unique: false},<br>
        software: {<br>
            type : Schema.ObjectId,<br>
            ref  : Software<br>
        }<br>
});

module.exports  = mongoose.model('User', User);

当启动User的对象时，如何为＆＃34;软件＆＃34;提供价值。以上？

var user1 = new User({<br>
        firstName: req.body.firstName,<br>
        lastName: req.body.lastName,<br>
        loginName: req.body.loginName,<br>
        password: req.body.password,<br>
        email: req.body.email,<br>
        ??????<br>
    });<br>

只需从客户端发送软件架构数据的_id，

像这样software : "50906d7fa3c412bb040eb578"（仅限字符串）然后你使用req.body.software获得价值

var user1 = new User({
        firstName: req.body.firstName,
        lastName: req.body.lastName,
        loginName: req.body.loginName,
        password: req.body.password,
        email: req.body.email,
        software:req.body.software
    });
