无法在 mysql 和 Node JS 中实现 CRUD 操作

Question

我正在尝试为我的 Node Js 应用程序实现 crud 操作。我正在按数据库使用 mysql。下面是代码。你们能不能请大家回顾一下，让我知道我哪里出错了。下面是我的 Jade 模板

  table#myTable.table.table-striped.table-bordered.table-sm.table-hover
         thead(style='background-color:indigo ; color:white; text-align: center;')
          tr
            th.th-sm No
            th.th-sm Product
            th.th-sm Owner Name
            th.th-sm Description
            th.th-sm Last update 
            th.th-sm Auditor
            th.th-sm Audit Date
            th.th-sm Any Action
            th.th-sm Result 
            th.th-sm Edit
            th.th-sm Delete

         tbody  
           each item in items ? items : [] 
             tr
               td=item.id
               td= item.product
               td= item.owner
               td= item.description
               td= item.date 
               td= item.Auditor
               td= item.adate 
               td= item.Action 
               td= item.result
               td
                a(href='/Edit/{item.id}')  Update 
               td
                a(href='/delete/{item.id}') Delete

这里是节点js代码

const express = require('express')
var mysql = require('mysql')
const bodyParser = require('body-parser')
const app = express()
var flash = require('connect-flash')
var session = require('express-session');

//...


app.use(session({ cookie: { maxAge: 60000 }, 
                  secret: 'woot',
                  resave: false, 
                  saveUninitialized: false}));


const port = 3000



app.use('/public', express.static(__dirname + '/public'));

app.use('/Dashboard', express.static(__dirname + '/views'));
app.use(flash());


app.use(bodyParser.urlencoded({extended: false}))
app.set('view engine', 'pug')

var connection = mysql.createConnection({
  host: 'localhost',
  user: 'root',
  password: '',
  database: 'audit',
  timezone: 'Z'
})
connection.connect(function(err){


  if (err) throw err;
  connection.query("SELECT * FROM auditresult", function (err, result) {
    if (err) throw err;
    console.log('Data has been Exported successfully'+ result.length);


  });

})

// DELETE 
app.get('/delete/:id', function(req, res, next) {


connection.query("DELETE FROM auditresult WHERE id =' " +req.params.id+" ' ", function(err, result) {

                res.redirect('Report')
            })
        })


// Edit 

app.get('/Edit/:id', function(req, res, next){
    var id= req.params.id;
    var sql="SELECT * from auditresult where id= " +req.params.id+" ;"
    connection.query(sql, function(err,items,fields){
        res.render('Update',{ product: items[0]});

    })

});

当我点击“编辑”时，我得到的是 URL“http://127.0.0.1:3000/Edit/%7Bitem.id%7D” 预先感谢您的帮助

我认为您需要在 jade 模板中更正此问题：

a(href='/Edit/' + item.id) 和 a(href='/delete/' + item.id)
