EJS Reference Error

November 23, 2016 140 views
Node.js MySQL

I have a Node.JS application that is hosted on Ubuntu 16.04. I am using EJS to display queried data from MySQL but I am getting a reference error like this

ReferenceError: /home/michaeluy/apps/michaeluy.me/views/index.html:130
 128| </div><br/><br/>
 129|         
 >> 130| <%=sec%>
 131| </div>
 132| </div>
 133| </body>

and here is the first bit of my server.js file:

var http = require('http');
var express = require('express');
var fs = require('fs');
var bodyParser = require('body-parser');
var mysql = require('mysql');
var connection  = require('express-myconnection');
var app = express();

app.use('/',express.static(__dirname + '/'));
app.use(bodyParser.urlencoded({ extended: false }));
app.engine('.html', require('ejs').__express);
app.set('view engine','html');

var connection = mysql.createConnection({
    host: '127.0.0.1',
    user: 'root',
    password: '',
    database: 'michaeluy'
});

app.get('/', function(req, res){
    connection.query("SELECT * FROM messages", function(err, rows, fields){
        if (err) throw err;
        res.render('index', {
            sec: rows[0].name
        });
     });
 });

I have tried using console.log at first to see if it is able to query the data correctly and it did but when I set the code on the html file for it to show up on the page itself. It gives back a reference error.

Hope someone can help here. Thanks in advance

  • Node.js is not one of the primary environments I code in but looking over reference materials this should be correct as long as the column is called "name" (not sure but this may be case sensitive so if it's "Name" that might explain this.

    What do you get if you place a console.log(rows[0]) in there to view the raw result?
