How to load a model in Autoload file in CodeIgniter 4

How can I load a model in ...\app\Config\Autoload.php?

Code:

namespace Config;

use CodeIgniter\Config\AutoloadConfig;

class Autoload extends AutoloadConfig {

    public function __construct() {
         //load here
         //i've tried,
         $my_model = new \App\Models\My_model();
         $my_model = model("App\Models\My_model");
    }

Nothing is working.

What is the correct way?

Looking for help. Thanks in advance.

This really depends on where you want to use this model. Autoloading does not work the same way as codeigniter 3 where everything would be put into the same super object.

If what you want is to use this model in a bunch of controllers then you can add that to your baseController in your initController function. Let's say you want to autoload the article model:

public $article;

public function initController(\CodeIgniter\HTTP\RequestInterface $request, \CodeIgniter\HTTP\ResponseInterface $response, \Psr\Log\LoggerInterface $logger)
{
    // Do Not Edit This Line
    parent::initController($request, $response, $logger);
    $this->article = new \App\Models\ArticleModel();
}

Now all your controllers that extend to your baseController can access this model with $this->article.

If what you want is to use the autoload and you can do that too, but not in a construct, for that you should use the classMap property.

 /**
 * -------------------------------------------------------------------
 * Class Map
 * -------------------------------------------------------------------
 * The class map provides a map of class names and their exact
 * location on the drive. Classes loaded in this manner will have
 * slightly faster performance because they will not have to be
 * searched for within one or more directories as they would if they
 * were being autoloaded through a namespace.
 *
 * Prototype:
 *
 *   $classmap = [
 *       'MyClass'   => '/path/to/class/file.php'
 *   ];
 *
 * @var array
 */
public $classmap = [
    'Article' => APPPATH . 'Models/ArticleModel.php'
];

But this option is more for classes that exist outside the normal codeigniter structure. So I would advise into using the first option.
