Phalcon – How to call a model in another controller? "Error: Class not found" – PHP

How to call a model in another controller?
I explain myself, I created a controller and I try to call another model in this controller, but I have the error "Error: Class not found".

You can see the code of my controller "Adserver" trying to call the model "Zone"

<?php
declare(strict_types=1);

use PhalconMvcModelZone as Zone;


class AdserveurController extends ControllerBase
{

    public function indexAction()
    {

        $id_zone= 1;
        
        $zone = Zone::findFirstByid_zone($id_zone);

        if(!zone){
            $this->flashSession->error('erreur id');
            return $this->response->redirect();
        }
        print_r ($id_zone);

        $zone = Zone::findFirst($hauteur);

        if(!zone){
            $this->fashSession->error('erreur hauteur');
            return $this->response->redirect();
        }
        
        $zone = Zone::findFirst($largeur);

        if(!zone){
            $this->fashSession->error('erreur hauteur');
            return $this->response->redirect();
        }
       
    }
   
    


  

}

On top of my controller, I tried the "use PhalconMvcModel" and the error persists.

My phalco version is 4.0

Could someone help me on how to call two models in a separate controller?

Thanks.

    I call multiple models from withing various controllers all the time and don’t have to declare "use PhalconMvcModelZone as Zone;" at the top.

    How is your Zone model file defined?

    if other_model has relation with Zone (defined in model) then :

    Zone->other_model->field;

    else in head of file

    "use PhalconMvcModel*other_model*;

    Try to define the namespace in your model, like:

    // app/models/Zone.php

<?php

namespace MyAppModels;

use PhalconMvcModel;

class Zone extends Model
{
     public function initialize()
     {
          $this->setSource('zone');
     }
 }

    Then in your loader:

    <?php

use PhalconLoader;

$loader->registerNamespaces(
   [
      'MyAppModels' => 'app/models'
   ]
);

$loader->register();

    Then in your controller:

    <?php

use MyAppModelsZone;

    Your current indexAction should work, but beware of what I commented to you regarding fields with underscores:

    $zone = Zone::findFirstByid_zone($id_zone); //won't work

$zone = Zone::findFirstByIdZone($id_zone);  //works

    Since you commented that you are a beginner, I would recommend you to review the MVC examples for Phalcon projects: https://github.com/phalcon/mvc So you get acquainted with namespaces in your app.

    Also, if you are working on a large application, it’s better that you register namespaces than directories for performance reasons, as detailed in the Docs: https://docs.phalcon.io/4.0/en/loader

    Ps. Reviewing indexAction there are some parameters that are not defined, like $hauteur and $largeur. Since $zone still is not working, these issues are still not visible –but they’ll show up after zone is working.
