How to join two tables? - Cannot read property 'getTableName' of undefined - node.js

Question

Users Model File
'use strict';
module.exports = (sequelize, DataTypes) => {
const user = sequelize.define('user', {
"access_role_id":DataTypes.INTEGER,
"user_type":{
type: DataTypes.ENUM,
values: ['A', 'V', 'U']
},
"login_access":{
type: DataTypes.ENUM,
values: ['APP', 'WEB', 'BOTH']
},
"username": DataTypes.STRING,
"email": DataTypes.STRING,
"updated_at":DataTypes.DATE,
"created_at":DataTypes.DATE,
}, {
"timestamps": false,
"createdAt": false,
'updatedAt': false,
"underscored": true,
"freezeTableName": false,
});
user.associate = function(models) {
// associations can be defined here
models.user.belongsTo(models.product, {targetKey: 'id',foreignKey: 'created_by'});
};
return user;
};
User Controller File
const dbConfig = require( '../../../db/models/index');
let users =require('../../../db/models/user')(dbConfig.sequelizeDB,dbConfig.Sequelize);
module.exports = {
// GET /customer/:id
getCustomer: function(req, res, next) {
users.findAll({
include: [{
model: users.product,
}]
}).then(function (stores) {
if (stores.length === 0) {
res.json('There are no stores in the database');
}
res.json(stores);
});
},
};
I am unable to get the product table data. It always shows an error:
Unhandled rejection TypeError: Cannot read property 'getTableName' of undefined.
Why the product table is not fetched in users model? How can I access this product table data by the users model?

Update your User Controller File as
const dbConfig = require( '../../../db/models/index');
let users =require('../../../db/models/user')(dbConfig.sequelizeDB,dbConfig.Sequelize);
let product=require('../../../db/models/product')(dbConfig.sequelizeDB,dbConfig.Sequelize);
module.exports = {
// GET /customer/:id
getCustomer: function(req, res, next) {
users.findAll({
include: [{
model: product,
}]
}).then(function (stores) {
if (stores.length === 0) {
res.json('There are no stores in the database');
}
res.json(stores);
});
},
};
