Bud pretazit a/alebo prrepisat ten kusok co hlada tu classu na nieco take:

<?php

  $classOverride = $this->formatPresenterClass($name . "override");
  if (class_exists($classOverride) {
   $class = $classOverride;
 } else {
  $class = $this->formatPresenterClass($name);
}

   if (!class_exists($class)) {
             throw new InvalidPresenterException("Cannot load presenter '$name', class '$class' was not found.");
   }

?>

uz som to presiel cez

<?php
/**

 */

namespace Core;

use Nette\Application\PresenterFactory;
use Nette\Application\IPresenter;


class CorePresenterFactory extends PresenterFactory{


    public function getPresenterClass(& $name) {


        $class = parent::getPresenterClass($name);



           $exploder = explode(':', $name);
           $exploder[count($exploder) - 1] = $exploder[count($exploder) - 1].'Override';
           $override = implode(':', $exploder);
           $override = str_replace('OverrideOverride', 'Override', $override);


           $class = $this->formatPresenterClass($override);
           if (!class_exists($class)) {
               throw new InvalidPresenterException("Cannot load presenter '$name', class '$class' was not found.");
           }


           $reflection = new \ReflectionClass($class);
           $class = $reflection->getName();


           if (!$reflection->implementsInterface(IPresenter::class)) {
               throw new InvalidPresenterException("Cannot load presenter '$name', class '$class' is not Nette\\Application\\IPresenter implementor.");
           } elseif ($reflection->isAbstract()) {
               throw new InvalidPresenterException("Cannot load presenter '$name', class '$class' is abstract.");
           }





        return $class;


    }

}

stale mi t ale vracia:

Argument 1 passed to Front\CoreModule\Presenters\HomepageOverridePresenter::__construct() must be an instance of Core\Models\Db, none given, called in /Applications/MAMP/htdocs/suchacms/vendor/nette/application/src/Application/PresenterFactory.php

je to mozne pls neako vyriesit?

dakujem, uz to slape :) vytvoril som jednoduchu extension ako si to mal ty. ak to niekto do buducna bude hladat, tak tu je inicializacia:

<?php

namespace Core;

use Nette\DI\CompilerExtension;
use Core\CorePresenterFactory;

class CoreExtension extends CompilerExtension
{

    public function beforeCompile()
    {

        $builder = $this->getContainerBuilder();
        $def = $builder->getDefinition($builder->getByType('Nette\Application\IPresenterFactory'));
        $original = $def->getFactory();
        $def->setFactory('Core\CorePresenterFactory', $original->arguments);

    }
}

ta trida dedi od base presenteru na urovni php, to nezmenis.. (pokud nepocitam prasarny s autoloadingem :))

myslel, som si, dakujem :) riesim si vlastne cms a ten override chcem len ak je neaka poziadavka custom a ma sa zobrazit componenta vsade. chcel som ju volat v basePresenteri, resp. ak by som potreboval do buducna neaku fciu specificku pre projekt supnut do base presenteru
