Node.js 猫鼬模型分离

我是node和mongodb的新手。我有以下猫鼬模型

import { model, Schema } from 'mongoose';
import Joi from '@hapi/joi';

const profileSchema = new Schema({
  user: {
    type: Schema.Types.ObjectId,
    ref: 'users',
  },
  handle: {
    type: String,
    minlength: 2,
    maxlength: 20,
    required: true,
    trim: true,
  },
  company: {
    type: String,
    minlength: 1,
    maxlength: 100,
    trim: true,

export default model('profile', profileSchema);

我在一个文件中创建了这个模型，它看起来太大了。那么，我应该把经验、教育和社会分为三个不同的模式吗？如果是这样，我应该怎么做？如果我把它们放在3个独立的模型中，我如何将它们与概要模型链接？举个例子会非常有用。

是的，你应该把它们分开。要链接它们，只需将概要模式Id作为字段放在其他模型上

const profileSchema = new Schema({
  userId: Schema.Types.ObjectId
})

const experienceSchema = new Schema({
  userId: Schema.Types.ObjectId
})
const educationSchema = new Schema({
  userId: Schema.Types.ObjectId
})

然后，您只需通过

userId

查询体验集合即可获得他们的体验。这是我推荐的方式

另一种方法是将

experienceID

放在参考体验模型的概要模式上，并可以使用

populate

方法填充字段。

您已经将用户链接到了您的概要模式，因此您也可以对体验、教育等使用相同的方法。您也可以查看子文档方法，谢谢。谢谢你的帮助，谢谢你的回答。
