Sample model

master.js:
module.exports = function(sequelize, DataTypes) {
	const detail = sequelize.define('master', {
		id: {
			type: DataTypes.INTEGER,
			allowNull: false,
			primaryKey: true,
			autoIncrement: true,
			field: 'pk_id'
		}
	}, {
		tableName: 'tbl_master'
	});

	return master;
};

detail.js:
module.exports = function(sequelize, DataTypes) {
	const detail = sequelize.define('detail', {
		id: {
			type: DataTypes.INTEGER,
			allowNull: false,
			primaryKey: true,
			autoIncrement: true,
			field: 'pk_id'
		},
		fk_id: {
			type: DataTypes.INTEGER,
			allowNull: false			
		}
	}, {
		tableName: 'tbl_detail'
	});

	detail.associate = function(models) {
		models.master.hasMany(detail, {
			as: 'detail',  // match with include association name
			foreignKey: 'fk_id',
			sourceKey: 'id'
		});

		detail.belongsTo(models.master, {
			foreignKey: 'fk_id',
			targetKey: 'id'
