trying to make an subscriber for Entity actions (CRUD) and cannot figure it out.

I know there is a way, where I can make listener and send him 3 different events, but that's not what I want to reach, I dont even think is good solution.

Event Subscriber

<?php



namespace AppEventListener;





use AppEntityLog;

use DoctrineORMEntityManagerInterface;

use DoctrineORMEventLifecycleEventArgs;

use DoctrineORMEvents;

use SymfonyComponentEventDispatcherEventSubscriberInterface;

use SymfonyComponentSecurityCoreAuthenticationTokenStorageTokenStorageInterface;



/**

 * Part of program created by David Jungman

 * @author David Jungman <davidjungman.web@gmail.com>

 */

class EntitySubscriber implements EventSubscriberInterface

{

    /**

     * @var EntityManagerInterface

     */

    private $em;



    /**

     * @var TokenStorageInterface

     */

    private $tokenStorage;



    public function __construct(TokenStorageInterface $tokenStorage, EntityManagerInterface $em)

    {

        $this->em = $em;

        $this->tokenStorage = $tokenStorage;

    }



    public static function getSubscribedEvents()

    {

        return array(

            Events::postPersist,

            Events::postUpdate,

            Events::postRemove,

        );

    }



    public function postUpdate(LifecycleEventArgs $args)

    {

        $this->logEvent($args, "remove");

    }



    public function postRemove(LifecycleEventArgs $args)

    {

        $this->logEvent($args, "remove");

    }



    public function postPersist(LifecycleEventArgs $args)

    {

        $this->logEvent($args, "create");

    }



    private function logEvent(LifecycleEventArgs $args, string $method)

    {

        $entity = $args->getEntity();

        if($entity->getShortName() != "Log")

        {

            $user = $this->tokenStorage->getToken()->getUser();

            $log = new Log();



            $log

                ->setUser($user)

                ->setAffectedTable($entity->getShortName())

                ->setAffectedItem($entity->getId())

                ->setAction($method)

                ->setCreatedAt();



            $this->em->persist($log);

            $this->em->flush();

        }

    }

}

and my Service.yaml part

AppEventListenerEntitySubscriber:

    tags:

    - { name: doctrine.event_subscriber, connection: default }

I have tried:

I've looked into these 2 official tutorials:
-https://symfony.com/doc/current/event_dispatcher.html
-https://symfony.com/doc/current/doctrine/event_listeners_subscribers.html

but neither helped.. when I use shown part of config, my computer freeze.

When I try to debug it, I can see these methods active
( php bin/console debug:event-dispatcher )

but they are listening on "event" event

Doctrine has it's own events handler/subscriber system. However, with the class SymfonyComponentEventDispatcherEventSubscriberInterface; that you are implementing, that is from the Symfony event system.

<?php

use DoctrineORMEvents;

use DoctrineCommonEventSubscriber;  // **the Doctrine Event subscriber interface**

use DoctrineCommonPersistenceEventLifecycleEventArgs;



class MyEventSubscriber implements EventSubscriber

{

    public function getSubscribedEvents()

    {

        return array(

            Events::postUpdate,

        );

    }



    public function postUpdate(LifecycleEventArgs $args)

    {

        $entity = $args->getObject();

        $entityManager = $args->getObjectManager();



        // perhaps you only want to act on some "Product" entity

        if ($entity instanceof Product) {

            // do something with the Product

        }

    }

}
