Symfony2的：決定一個控制器從開發環境或生產環境

Question

我已經開發了一個控制器使用JSON回答到AJAX請願書呼籲：

class PeopleController extends Controller 
{ 
public function listAction() 
{ 
    $request = $this->getRequest(); 

    // if ajax only is going to be used uncomment next lines 
    //if (!$request->isXmlHttpRequest()) 
    //throw $this->createNotFoundException('The page is not found'); 

    $repository = $this->getDoctrine()->getRepository('PeopleManagerBundle:People'); 
    $items = $repository->findAll(); 

    // yes, here we are retrieving "_format" from routing. In our case it's json 
    $format = $request->getRequestFormat(); 

    return $this->render('::base.'.$format.'.twig', array('data' => $items)); 

} 

我已經啓用HTML視圖，如它對於調試非常有用，但我想限制在應用程序處於生產階段時使用_format = html調用此控制器的可能性。如何確定控制器是從開發環境還是從生產環境調用？

檢索服務容器內核並使用內置的方法：

$kernel = $this->get('kernel'); 
$kernel->isDebug(); // in most cases: false if env=prod, true if env=dev/test 
$kernel->getEnvironment(); // prod, dev, test
