我如何在另一个内部引用 1 ZCCADDEDB567ABAE643E15DCF0974E503Z Schema 作为其属性？

Question

我正在尝试制作一个商店应用程序并创建了两个 mongoose 模式。 Order.js 和 Product.js，我想将产品模式引用为订单模式的属性。

Order.js

const mongoose = require('mongoose');
const Product=require('../models/product.js');

const orderSchema = new mongoose.Schema(

    {
        date: {
             type:Date, 
             default: Date.now},
        customerName: String,
        customerAddress: String,
        creditCard: Number,
        products:[] //product model
   
    },
     { timestamps: true }
);

产品.js

const mongoose = require('mongoose');

const productSchema = new mongoose.Schema(
    {
        name: String,
        price: Number,
        category: String
    },
    { timestamps: true }
);

const Product = mongoose.model('Product', productSchema);
module.exports= Product;

Answer 1

This is my approach when it comes to nested schemas in mongoose: first you have to create an object of your Product schema, to avoid duplicating your Product model, you can create an object:

产品

使用您的字段，然后通过简单地创建您的产品架构const Product = new Schema(product); ，然后您可以在 order.js 中在此处导入产品 object 并声明您的架构如下：

import product;
const Order = new Schema({
......
......
order : {
   type : product , 
   ......
}
})
