Load sequelize models from a folder

SequelizeModels.js

/*
* Not actually a JS file; Normally you'd break these components up.
*/

/* creating the database connection */
var db = new Sequelize('database', 'username', 'password', ...);

/* loading the models */
var fs = require('fs');
var path = require('path');

var models = {};
fs.readdirSync('model/').forEach(function(filename) {
	var model = {};
	model.path = path.join(__dirname, 'model/', filename)
	model.name = filename.replace(/\.[^/.]+$/, "");
	model.resource = db.import(model.path);
	// model.service = epilogue.resource({model: model.resource});
	models[model.name] = model;	
});

/* Student.js - Example of a complex model */
var path = require('path');

module.exports = function(sequelize, DataTypes) {	
	// Define resource
	var Student = sequelize.define('Student',	{
		firstname: DataTypes.STRING,
		lastname: DataTypes.STRING,
		name: { type: DataTypes.STRING }
	},
	// Other properties
	{
		indexes: [{fields: ['firstname', 'lastname']}]
	});

	var Course = sequelize.import(path.join(__dirname, 'course'));
	Student.hasMany(Course);
	
	return Student;
}

in my line code error model.resource = db.import(model.path);
what's wrong with my line of code?

lines code

.import() was removed in sequelize 6.0.
