Node.js E11000重复密钥错误集合：amaxon.products索引：name_1重复密钥：{name:“Nike SLim Shirt”}

以下是我的

productModel.js

中的

productShema

模型：

import mongoose from 'mongoose'

const productSchema = new mongoose.Schema(
  {
    name: { type: String, required: true, unique: true },
    image: { type: String, required: true },
    brand: { type: String, required: true },
    category: { type: String, required: true },
    description: { type: String, required: true },
    price: { type: Number, required: true },
    countInStock: { type: Number, required: true },
    rating: { type: Number, required: true },
    numReviews: { type: Number, required: true },
  },
  {
    timestamps: true,
  }
)
const Product = mongoose.model('Product', productSchema)

export default Product

import express from 'express'
import Product from '../models/productModel.js'
import expressAsyncHandler from 'express-async-handler'
import data from '../data.js'

const productRouter = express.Router()

productRouter.get(
  '/',
  expressAsyncHandler(async (req, res) => {
    const products = await Product.find({})
    res.send(products)
  })
)

productRouter.get(
  '/seed',
  expressAsyncHandler(async (req, res) => {
    // await Product.remove({});
    const createdProducts = await Product.insertMany(data.products)
    res.send({ createdProducts })
  })
)

productRouter.get(
  '/:id',
  expressAsyncHandler(async (req, res) => {
    const product = await Product.findById(req.params.id)
    if (product) {
      res.send(product)
    } else {
      res.status(404).send({ message: 'Product not found' })
    }
  })
)

export default productRouter

这就是我在

productRouter.js中使用它的方式：

import mongoose from 'mongoose'

const productSchema = new mongoose.Schema(
  {
    name: { type: String, required: true, unique: true },
    image: { type: String, required: true },
    brand: { type: String, required: true },
    category: { type: String, required: true },
    description: { type: String, required: true },
    price: { type: Number, required: true },
    countInStock: { type: Number, required: true },
    rating: { type: Number, required: true },
    numReviews: { type: Number, required: true },
  },
  {
    timestamps: true,
  }
)
const Product = mongoose.model('Product', productSchema)

export default Product

import express from 'express'
import Product from '../models/productModel.js'
import expressAsyncHandler from 'express-async-handler'
import data from '../data.js'

const productRouter = express.Router()

productRouter.get(
  '/',
  expressAsyncHandler(async (req, res) => {
    const products = await Product.find({})
    res.send(products)
  })
)

productRouter.get(
  '/seed',
  expressAsyncHandler(async (req, res) => {
    // await Product.remove({});
    const createdProducts = await Product.insertMany(data.products)
    res.send({ createdProducts })
  })
)

productRouter.get(
  '/:id',
  expressAsyncHandler(async (req, res) => {
    const product = await Product.findById(req.params.id)
    if (product) {
      res.send(product)
    } else {
      res.status(404).send({ message: 'Product not found' })
    }
  })
)

export default productRouter

在
data.products
中，我有6个产品，然后我尝试从
http://localhost:5000/api/products/seed
此地址并向我显示：

“E11000重复密钥错误集合：amaxon.products索引：name_1重复密钥：{name:“Nike SLim Shirt”}”

当我试图从
http://localhost:5000/api/products
它只提供一种产品。如何修复此问题？
您正在尝试插入数据，而不是使用
查找
。选中此项：

productRouter.get(
  '/seed',
  expressAsyncHandler(async (req, res) => {
    // await Product.remove({});
    const createdProducts = await Product.find({})
    res.send({ createdProducts })
  })
)

由于
名称
属性设置为唯一，请确保：

再次调用
种子
端点之前，删除
产品mongo集合中存储的所有数据。（您已将其注释掉-
等待产品。删除（{}）；
）

data.js
中的所有名称都是唯一的
