Question

现在我在一个商店项目中工作，我有一个关于猫鼬js中的模型和模式以及如何在我们的项目中使用它们的问题。

订单模型

在CartItemSchema中，我还引用产品和商店

在OrderSchema中，我引用的是CartItemSchema

const mongoose = require('mongoose');

const CartItemSchema = new mongoose.Schema({
  product: [{ type: mongoose.Schema.ObjectId, ref: 'Product' }], <-- Product Schema
  quantity: Number,
  shop: [{ type: mongoose.Schema.ObjectId, ref: 'Shop' }],       <-- Shop Schema
  status: {
    type: String,
    default: 'Not processed',
    enum: ['Not processed', 'Processing', 'Shipped', 'Delivered', 'Cancelled']
  }
});

const OrderSchema = new mongoose.Schema({
  products: [CartItemSchema],                   <-- CartItemSchema Schema
  customer_name: {
    type: String,
    trim: true
  },
  customer_email: {
    type: String,
    trim: true,
    match: [/.+.+\..+/, 'Please fill a valid email address']
  },
  deliveryAddress: {
    street: { type: String, required: 'Street is required' },
    city: { type: String, required: 'City is required' },
    state: { type: String, required: 'State is required' },
    zipcode: { type: String, required: 'Zip Code is required' },
    country: { type: String, required: 'Country is required' }
  },
  payment_id: {},
  updated: Date,
  created: {
    type: Date,
    default: Date.now
  },
  user: { type: mongoose.Schema.ObjectId, ref: 'User' }
});


const Order = mongoose.model('Order', OrderSchema);

module.exports = Order;

创建订单控制器

exports.createOrder = asyncMiddleware(async (req, res, next) => {
  const order = new Order({
    user: req.user,
    deliveryAddress: req.body.deliveryAddress,
    products: req.body.products,               <-- referencing the products in OrderSchema
    customer_name: req.body.customer_name,
    customer_email: req.body.customer_email
  });

  order.save((err, result) => {
    if (err) {
      return next(new ErrorResponse(err, 400));
    }
    res.status(200).json(result);
  });
});

但是，我的问题是，当我根据在订单模型中指定的字段创建新的订单时，如何引用产品字段，到目前为止，我已经做了类似的事情。 ..

products: req.body.products,

但是，这不能按预期方式工作，我只能获取产品的ObjectId，而shop的ObjectId是一个空数组。
