CodeIgniter 4 Models preloading

You should preload components (like models, etc.) by using initController() as demonstrated here.

There is a controller named BaseController distributed with the framework that is included exactly for the purpose of doing what you want. Look closely at how initController() is defined in app\Controllers\BaseController.

PHP Code:

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);

 //--------------------------------------------------------------------
 // Preload any models, libraries, etc, here.
 //--------------------------------------------------------------------
 // E.g.:
 // $this->session = \Config\Services::session();
} 


Put your model loading in the commented section near the bottom. (Oh, and remove the comments.) It might look like this

PHP Code:

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);

 //--------------------------------------------------------------------
 // Preload any models, libraries, etc, here.
 //--------------------------------------------------------------------

        $this->vartotojai =  new vartotojai_model();
} 


Then extend any controllers that need this model from BaseController

PHP Code:

namespace App\Controllers;

use CodeIgniter\Controller;

class NewController extends BaseController
{
        //use $this->vartotojai as needed
} 


On a side-note: Please don't use Lightshot or the like to show code. Instead, copy & paste and surround the lines of code with [php] ...lines of code... [\php] tags. Thanks.
