Symfony 2.8 Services issue - php

Question

Since the last 4 hours I'm trying to understand the logic of Symfony 2 services and how they integrate in the application...
Basically I'm trying to set my EntityManager via a service and use it in a controller
I have the following structure
Bundle1/Controller/Bundle1Controller.php
Bundle1/Services/EntityService.php
Bundle2/Controller/Bundle2Controller.php
Bundle3/Controller/Bundle3Controller.php
....
I'm trying to make a REST API with different entry points, that's why I use multiple bundles bundle2,bundle3....
The logic is the following:
A POST is fired to Bundle2/Controller/Bundle2Controller.php
Bundle2Controller.php instances a new() Bundle1Controller.php
Inside Bundle1Controller I want to access a service entity_service in order to get my EntityManager
I have 2 cases in which I manage to land...
In Bundle1/Controller/Bundle1Controller if I try $this->container or $this->get('entity_service') I get a null everytime
If I set the container in Bundle2/Controller/Bundle2Controller and try $this->get('entity_service') I get You have requested a non-existent service "entity_service"
I will place all the code below
Bundle1/Controller/Bundle1Controller
<?php
namespace Bundle1\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use EntityBundle\Entity\TestEntity;
use Symfony\Component\DependencyInjection\ContainerAwareInterface;
class Bundle1Controller extends Controller
{
/**
* #param $response
* #return array
*/
public function verifyWebHookRespone($response){
$em = $this->get('entity_service')->getEm();
$array = json_decode($response);
$mapping = $em->getRepository('EntityBundle:TestEntity')
->findBy(["phone" => $array['usernumber']]);
return $mapping;
}
}
Bundle2/Controller/Bundle2Controller.php
<?php
namespace Bundle2\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Bundle1\Controller\Bundle1Controller;
class Bundle2Controller extends Controller
{
public function webhookAction(Request $request)
{
$data = $request->request->get('messages');
$model = new Bundle1Controller();
$responseMessage = $model->verifyWebHookRespone($data);
return new Response($responseMessage, Response::HTTP_CREATED, ['X-My-Header' => 'My Value']);
}
}
Bundle1/Services/EntityService.php
<?php
namespace EntityBundle\Services;
use Doctrine\ORM\EntityManager;
use Symfony\Component\DependencyInjection\Container;
class EntityService
{
protected $em;
private $container;
public function __construct(EntityManager $entityManager, Container $container)
{
$this->em = $entityManager;
$this->container = $container;
}
/**
* #return EntityManager
*/
public function getEm()
{
return $this->em;
}
}
services.yml
services:
entity_service:
class: Bundle1\Services\EntityService
arguments: [ "#doctrine.orm.entity_manager" , "#service_container" ]
Can anyone please help me with something regarding this issue?
How can I register a service and call it from anywhere no matter the bundle or another service?

Answer 1

You should check where your services.yml is located and whether it is imported in the config.yml
You can't just instantiate a controller and expect it to work, you need to set the container.
But you can call EntityManager without needing any other service by using;
$this->get('doctrine.orm.entity_manager');
I can't understand your structure or what you are trying to achieve, but those are the options to go about if you want to keep this structure.
