可捕獲致命錯誤：傳遞給（...）\ Handler \ FlightHandler :: __ construct（）的參數1必須是Symfony \ Component \ Form \ Form的一個實例

Question

我有一個很大的bug，只花了2個小時時間... 我改變了我的FlightType中的configureOptions方法，但它不是解決方案。

錯誤：

Catchable Fatal Error: Argument 1 passed to Test\FrontBundle\Form\Handler\FlightHandler::__construct() must be an instance of Symfony\Component\Form\Form, none given, called in /Users/macbookpro/Desktop/Projets Web/Emirates/app/cache/dev/appDevDebugProjectContainer.php on line 834 and defined

我剛編碼我service.yml這樣的：

services: 
    flight_form: 
     factory_service: form.factory 
     factory_method: createNamed 
     class: Symfony\Component\Form\Form 
     arguments: 
      - flight 
      - flight_form 

    flight_type: 
     class: Test\FrontBundle\Form\Type\FlightType 
     tags: 
      - { name: form.type, alias: flight_form } 

    flight_handler: 
     class: Test\FrontBundle\Form\Handler\FlightHandler 
     argument: [@flight_form, @request] 
     scope: request 

FlightController.php

 public function createAction(Request $request) { 


      $formHandler = $this->get("flight_handler"); 
      $form = $formHandler->getForm(); 

      if ($formHandler->process()) { 
       $em = $this->getDoctrine()->getManager(); 
       $em->persist($form->getData()); 
       $em->flush(); 

       return $this->redirect($this->generateUrl("test_front_flight_list")); 
      } 

      return $this->render('TestFrontBundle:Flight:create.html.twig', array('form' => $form->createView())); 

     } 
    } 

FlightHandler.php

(...) 

class FlightHandler { 

    protected $form; 
    protected $request; 

    public function __construct(Form $form, Request $request) { 
     $this->form = $form; 
     $this->request = $request; 
    } 

    public function getForm() { 
     return $this->form; 
    } 

    public function process() { 

     $this->form->handleRequest($this->request); 

     if ($this->request->isMethod("POST") && $this->form->isValid()) { 
      return true; 
     } 
     return false; 
    } 

} 

FlightType.php

public function setDefaultOptions(OptionsResolverInterface $resolver) { 
    /** @var OptionResolver $resolver */ 
    $this->configureOptions($resolver); 
} 

public function configureOptions(OptionsResolver $resolver){ 
    $resolver->setDefaults(array(
     "data_class" => 'Test\FrontBundle\Entity\Flight' 
    )); 

Answer 1

沒關係。在我的service.yml中，最後，「參數」必須是「參數」
