Message.Create is not a function sequelize cli - mysql

Question

I have installed mysql sequelize in my project then I creadted Message Model using sequelize command which create model and migration file .I also given the db credentials in config.json file.Now I am trying to insert record in my db but getting this error here is my model file
DO i need to make db connection explicitly or it auto picks the
credential from config.json file to make connection ?
models/messages.js
'use strict';
module.exports = (sequelize, DataTypes) => {
var Messages = sequelize.define('Messages', {
room: DataTypes.STRING,
nickname: DataTypes.STRING,
message: DataTypes.STRING,
receiver: DataTypes.STRING
}, {
classMethods: {
associate: function(models) {
// associations can be defined here
}
}
});
return Messages;
};
here is config.json file
config/config.json
{
"development": {
"username": "root",
"password": "asad",
"database": "chat",
"host": "127.0.0.1",
"dialect": "mysql"
},
"test": {
"username": "root",
"password": null,
"database": "database_test",
"host": "127.0.0.1",
"dialect": "mysql"
},
"production": {
"username": "root",
"password": null,
"database": "database_production",
"host": "127.0.0.1",
"dialect": "mysql"
}
}
and here is my server file to save record
app.js file
var express = require('express');
var router = express.Router();
var app = express();
var server = require('http').createServer(app);
server.listen(4000);
var Messages=require('../models/Messages.js');
router.post('/', function(req, res, next) {
var a =req.body;
Messages.create(a).then(() => {
console.log('success ')
})
})

Answer 1

make sequelize connection instance and export it, please use config according to your environment
const sql = new Sequelize(config.database, config.username, config.password, {
host: config.host,
dialect: config.dialect,
pool: {
max: 5,
min: 0,
idle: 10000
},
});
module.export = sql;
In your app.js import sql instance and connect your db before starting your server.
var express = require('express');
var router = express.Router();
var app = express();
var server = require('http').createServer(app);
var sql = require(./sql);
sql.authenticate().then(()=>{
server.listen(4000);
});
var Messages= sql.import('../models/Messages.js');
router.post('/', function(req, res, next) {
var a =req.body;
Messages.create(a).then(() => {
console.log('success ')
})
})
