在 Mongoose 模式中保存数组 [英] Save arrays in Mongoose schema

问题描述

假设我想要一个数据模式:每个用户可以拥有多台笔记本电脑，有些笔记本电脑可用，有些则不可用.我希望我能得到一些像，

Suppose I want to have a data schema: every user can have many laptops, and some laptops are available some are not. I hope that I can get some schema like,

User
| userId: 1
| laptops:
   | laptopId: 1  available: true  //default
   | laptopId: 2  available: true  

我如何定义这样的架构?以下不正确:

How can I define such schema? The following is not correct:

const User = new mongoose.Schema({
  userId: {
    type: String,
    index: { unique: true }
  },
  laptops: {
    laptopId: String,
    available: Boolean
  }
});

如何在 node.js 的 Mongoose 中定义这个?

推荐答案

你只需使用方括号，就像这个例子:

You simply use square brackets, like in this example:

const User = new mongoose.Schema({
  userId: {
    type: String,
    index: { unique: true }
  },
  laptops: [{
    laptopId:{
        type: String
    },
    available: {
        type: Boolean
    }
  }]
});

查看官方文档以了解允许的架构类型.
