我正在尝试使用请求创建新的购物车模式 [英] I am trying to create a new Cart schema with a request

问题描述

我的数据没有正确保存

这是我的Schema

This is my SChema

  const mongoose = require('mongoose');

const ProductSchema = mongoose.Schema({
  colorC: String,
  sizeC: String,
  date: Date,
  title: String,
  transactionID: Number,
  count: Number
});

const CartSchema = mongoose.Schema({
  products: [ProductSchema]
});

const Cart = mongoose.model('Cart', CartSchema);

module.exports = {
  cartModel: mongoose.model('Cart', CartSchema),
  productModel: mongoose.model('Product', ProductSchema)
};

这是我的发帖请求

const express = require('express');
const Cart = require('../models/Cart');
const models = require('../models/Cart');
const router = express.Router();

router.post('/', async (req, res) => {
  const { colorC, sizeC, date, title, transactionID, count } = req.body;
  try {
    const newPurchase = new models.cartModel({
      products: [
        {
          title,
          colorC,
          sizeC,
          count,
          date,
          transactionID
        }
      ]
    });

    const purchase = await newPurchase.save();

    res.json(purchase);
  } catch (err) {
    console.error(err.message);
    res.status(500).send('Server Error');
  }
});

module.exports = router;

当我将数据作为包含两个对象的数组发送时，没有数据显示出来，例如这应该显示我输入的对象. 当我发送此消息时，服务器不会在阵列中保存任何产品.

When i send the data as an array containing two objects none of the data shows up for instance this is supposed to show the object i input. When i send this the server does not save any products in the array.

这就是我要发送到服务器的内容

This is what i am sending to the server

[{

"colorC": null,
"count": 1,
"date": "Mon Jul 29 2019 02:08:07 GMT-0400 (Eastern Daylight Time)",
"sizeC": "Small",
"title": "COMME DES GARCONS TEE",
"transactionID": 1564380487732

},{

"colorC": null,
"count": 1,
"date": "Mon Jul 29 2019 02:08:07 GMT-0400 (Eastern Daylight Time)",
"sizeC": "Small",
"title": "COMME DES GARCONS TEE",
"transactionID": 1564380487732

}]

这是保存在数据库中的数据

This is the data saved in the Database

{
    "_id":{"$oid":"5d42ab9f4ec81021f0136e95"},
    "products":[{"_id":{"$oid":"5d42ab9f4ec81021f0136e94"}}]
    ,"__v":{"$numberInt":"0"}
    }

我希望数据看起来像这样

I am expecting the data to look like this

{
    "_id": "5d439bc758a1f004b876bac3",
    "products": [
        {
            "_id": "5d439bc758a1f004b876bac4",
            "title": "COMME DES GARCONS TEE",
            "colorC": null,
            "sizeC": "Small",
            "count": 1,
            "date": "2019-07-29T06:08:07.000Z",
            "transactionID": 1564380487732
        }
    ],
    "__v": 0
}

推荐答案

必须重新构建此文件

 const express = require("express");
    const models = require("../models/Cart");
    const router = express.Router();

    router.post("/", (req, res) => {
      const newPurchase = new models.cartModel({
        products: req.body.map(element => {
          const { colorC, sizeC, date, title, transactionID, count } = element;
          return { colorC, sizeC, date, title, transactionID, count };
        })
      });

      newPurchase
        .save()
        .then(purchase => res.json(purchase))
        .catch(err => {
          console.error(err.message);
          res.status(500).send("Server Error");
        });
    });

    module.exports = router;
