Question

我是MongoDB / Mongoose的新手，并试图弄清楚如何映射Schema之间的关系。我不认为问题出在.populate（）上。在创建新用户和客户端时，我看不到集合中反映的关系

用户（通过本地/社交网站登录）有许多客户端。一组客户端属于1个用户

这是申报外键的正确方法吗？ {type：Schema.Types.ObjectId，ref：＆＃39; Client＆＃39;}
两个架构是否应该让彼此的外键相互关联？
创建用户/客户端是否需要任何其他代码才能显示外键数据？我读了一些关于populate（）

用户

var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var userSchema = new Schema({

local: {
    id: String,
    email: String,
    password: String,
    name: String,
    mobile: String,
    clients: {type: Schema.Types.ObjectId, ref: 'Client'}

},

google: {
    id: String,
    token: String,
    email: String,
    name: String,
    clients: {type: Schema.Types.ObjectId, ref: 'Client'}

}

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

客户端

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

var clientSchema = new Schema({

    id: String,
    firstname: String,
    lastname: String,
    mobile: String,
    user: {type: Schema.Types.ObjectId, ref: 'User'}

});

module.exports = mongoose.model('Client', clientSchema);

创建用户

app.post("/api/user", function (req, res) {
const user = req.body;
console.log(user);

User.findOne({ 'local.email': user.email },
  function (err, result) {
    if (err) {
      console.log(err);
      handleError(err, res);
      return;
    }
    if (result) {
      res.status(500).send("Email already exists in database");
    } else {
      var newUser = new User();
      newUser.local.password = generateHash(user.password);
      newUser.local.email = user.email;
      newUser.local.name = user.name;
      newUser.local.mobile = user.mobile;
      newUser.save(function (err, result) {
        res.status(201).send("User added to database");
      });
    }

  });
 });

创建客户端

app.post("/api/client", function (req, res) {
const client = req.body;
console.log(client);

Client.findOne({
  $and: [
         { firstname: client.firstname },
         { lastname: client.lastname }
       ]
},
  function (err, result) {
    if (err) {
      console.log(err);
      handleError(err, res);
      return;
    }
    if (result) {
      res.status(500).send({msg:"Client already exists in database"});
    } else {
      var newClient = new Client();
      newClient.firstname = client.firstname;
      newClient.lastname = client.lastname;
      newClient.mobile = client.mobile;
      newClient.save(function (err, result) {
        res.status(201).send("Client added to database");
      });
    }

  });

 });
