试图从mongodb中显示玉器中的数据 [英] trying to display data in jade from mongodb

问题描述

试图显示从猫鼬模式到翡翠Temaplate的数据，但是不管我尝试什么，它都无法正常工作，所以请帮助我，谢谢.

trying to display data from mongoose schema to jade temaplate but it dosent work no matter what i try , so please help me and thanks .

首先这是我的书模式模型/book.js

first here is my book schema models/book.js

  const mongoose = require('mongoose')
const schema = mongoose.Schema

const BookSchema = new schema({
  title: String,
  author: String,
  isbn: Number,
  date: { type: Date, default: Date.now},
  description: String
})


module.exports = mongoose.model('Book', BookSchema)

这是我的书籍模型控制器

and here is my controller for the book model

    const Book = require('../models/book')
const express = require('express')
router = express.Router()


router.route('/books')
  // Create a book
  .post( (req, res) => {
    const book = new Book()
    book.name = req.body.name

    book.save( (err) => {
      if (err)
        res.send(err)

      console.log('Book created! ')
    })
  })

  //get all books
  .get( (req, res) => {
    Book.find( (err, books) => {
      if (err)
        res.send(err)

      res.render('books', {title: 'books list'})
    })
  })




module.exports = router

最后是我的翡翠模板

    extends layout

block content
  if books
    each book in books
      h1 #{book.title}

推荐答案

您的代码中需要进行多个错误/修改.

There are multiple mistakes/modifications required in your code.

1. 在查找时，最好以{}作为第一个输入.

在渲染书籍模板时，您使用books变量显示书籍列表，但不是从路径发送它.您需要在res.render中发送books.

When rendering the book template, you are using books variable to show list of books, but you are not sending it from the route. you need to send books in res.render.

尝试一下:

router.route('/books')
  // Create a book
  .post( (req, res) => { 
    const book = new Book()
    book.name = req.body.name

    book.save( (err) => {
        res.send(err)

      console.log('Book created! ')
    })
  })

  //get all books
  .get((req, res) => {
    Book.find({},(err, books) => { 
      if (err)
        res.send(err)

      res.render('books', {title: 'books list' , books : books})//need to send the books variable to the template.
    })
  })
