Node.js 使用mongoDB的Express模型中的一对多关系

这是

doctors.js

模型：

var mongoose = require('mongoose'), Schema = mongoose.Schema;
var Patient = require('./patient.js');

var doctorSchema = mongoose.Schema({

  firstName: String,
  lastName: String,
  qualifications: String,
  photo: Buffer,
  _patients: [{ type: Schema.Types.ObjectId, ref: 'Patient' }]
});

var Doctor = mongoose.model('Doctor', doctorSchema);
module.exports = Doctor;

var mongoose = require('mongoose');
var Doctor = require('./doctor.js');

var patientSchema = mongoose.Schema({
  firstName: String,
  lastName: String,
  dob: String,
  gender: String,
  primaryDiagnosis: String,
  duration: String,
  _doctorIncharge: {type: Number, ref: 'Doctor'},
  hospitalNumber: String,
  photo: Buffer
});

var Patient = mongoose.model('Patient', patientSchema);
module.exports = Patient;

这是

patients.js

模型：

var mongoose = require('mongoose'), Schema = mongoose.Schema;
var Patient = require('./patient.js');

var doctorSchema = mongoose.Schema({

  firstName: String,
  lastName: String,
  qualifications: String,
  photo: Buffer,
  _patients: [{ type: Schema.Types.ObjectId, ref: 'Patient' }]
});

var Doctor = mongoose.model('Doctor', doctorSchema);
module.exports = Doctor;

var mongoose = require('mongoose');
var Doctor = require('./doctor.js');

var patientSchema = mongoose.Schema({
  firstName: String,
  lastName: String,
  dob: String,
  gender: String,
  primaryDiagnosis: String,
  duration: String,
  _doctorIncharge: {type: Number, ref: 'Doctor'},
  hospitalNumber: String,
  photo: Buffer
});

var Patient = mongoose.model('Patient', patientSchema);
module.exports = Patient;

这是让一对多关系发挥作用的方式吗
