Twig Extension içinde Symfony ContainerInterface kullanabilme

config.yml services altında

  ojstr.twig.ojs_extension:
  class: Sfapp\Common\Twig\SfappExtension
  arguments: [@service_container]
  tags:
    - { name: twig.extension } 


arguments sayesinden extension dosyasında service container'a erişebileceğim.

	<?php
	namespace Sfapp\Common\Twig;
	use Symfony\Component\DependencyInjection\ContainerInterface as Container;
	class SfappExtension extends \Twig_Extension {
	private $container;
	public function __construct(Container $container = null) {
	$this->container = $container;
	}
	public function getFunctions() {
	return array(
	'testuser' => new \Twig_Function_Method($this, 'checkUser', array('is_safe' => array('html')))
	);
	}
	public function checkUser() {
	$securityContext = $this->container->get('security.context');
	if ($securityContext->isGranted('IS_AUTHENTICATED_FULLY')) {
	return "ok";
	}
	return "notok";
	}
	public function getName() {
	return 'sfapp_extension';
	}
	}
