I am attempting to add a new record to a MYSQL table using sequelize.
After installing sequelize and mysql, I ran the following commands:
npm install --save sequelize
npm install --save mysql
In my app.js file, I included the following:
var Sequelize = require('sequelize');
In my db.js file, I set up the database connection as follows:
var Sequelize = require('sequelize');
var sequelize = new Sequelize('randomdb', 'root', 'root', {
host: 'localhost',
dialect: 'mysql',
port : 8889,
pool: {
max: 5,
min: 0,
idle: 10000
}
});
exports.sequelize = sequelize;
module.exports = Sequelize;
Within routes/index.js, I defined the routes for adding a user:
var express = require('express');
var router = express.Router();
var sequelize = require('../db').sequelize;
router.get('/', function (req, res, next) {
res.render('index', {title: 'Express'});
});
router.get('/adduser', function (req, res) {
var User = sequelize.define('users', {
first_name: Sequelize.STRING
});
sequelize.sync().then(function () {
return User.create({
first_name: 'janedoe'
});
}).then(function (jane) {
console.log(jane.get({ plain: true }));
});
});
module.exports = router;
An error was encountered with the message:
Cannot read property 'define' of undefined
TypeError: Cannot read property 'define' of undefined
To address this issue, I made the following changes:
EDIT 2
Updated db.js:
var Sequelize = require('sequelize');
var sequelize = new Sequelize('randomdb', 'root', 'root', {
host: 'localhost',
dialect: 'mysql',
port: 8889,
pool: {
max: 5,
min: 0,
idle: 10000
},
define: {
timestamps: false
}
});
var db = {};
db.sequelize = sequelize;
db.Sequelize = Sequelize;
module.exports = db;
Created models/user.js:
var db = require('../db'),
sequelize = db.sequelize,
Sequelize = db.Sequelize;
var User = sequelize.define('random', {
first_name: Sequelize.STRING
});
module.exports = User;
Modified routes/index.js:
var express = require('express');
var router = express.Router();
var db = require('../db'),
sequelize = db.sequelize,
Sequelize = db.Sequelize;
var User = require('../models/user');
router.get('/adduseryes', function (req, res) {
sequelize.sync().then(function () {
return User.create({
first_name: 'janedoe'
});
}).then(function (jane) {
res.send("YES");
});
});
module.exports = router;
