Add this link to your composer.json file:

"require": {

  "tfox/di-tools-bundle": "1.0.0"

...and run php composer.json update

The next step is to add to AppKernel.php the next line:

$bundles = array(
  new TFox\DiToolsBundle\TFoxDiToolsBundle()


Injection of a service into super class and all sub class controllers:

Here is provided a simple example of dependency injection using DiToolsBundle. For instance, we have two controllers:

  1. TestBundle\Controller\SuperController : A super class controller with protected property "entityManager". Our purpose is to inject here an Entity Manager so that it would be visible in sub class controllers.

  2. TestBundle\Controller\SubController, which extends a SuperController and uses its entity manager.

Our code will be like below:


namespace TestBundle\Controller;

use TFox\DiToolsBundle\Annotation as Di;
use TFox\DiToolsBundle\Controller\DiToolsInjectableInterface;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class SuperController extends Controller implements DiToolsInjectableInterface {

	 * @Di\Inject("doctrine.orm.default_entity_manager")
	 * @var \Doctrine\ORM\EntityManager
	protected $entityManager;


namespace TestBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration as Sensio;

 * @Sensio\Route("/sub")
class SubController extends SuperController {
	 * @Sensio\Route
	 * @Sensio\Template
	public function indexAction()
    //Any operations with injected entity manager here. For instance we will get some article
		$article = $this->entityManager->getRepository('TestBundle:Article')
		return array('article' => $article);
