傳遞多種形式對不同業務的Symfony2

Question

我的工作在這裏我們使用DependencyInjection項目視圖定義的，所以我必須在src\Common\CommonBundle\Resources\config\services.yml定義如下：

services: 
    address.form: 
     class: Wuelto\Common\CommonBundle\Controller\FormAddressController 
     arguments: [@form.factory, @doctrine.orm.entity_manager] 
    address_extra_info.form: 
     class: Wuelto\Common\CommonBundle\Controller\FormAddressExtraInfoController 
     arguments: [@form.factory, @doctrine.orm.entity_manager] 

而且src\Company\RegisterCompanyBundle\Resources\config\services.yml

services: 
    registercompany.form: 
     class: Wuelto\Company\RegisterCompanyBundle\Controller\FormRegisterCompanyController 
     arguments: [@form.factory, @doctrine.orm.entity_manager] 

這是控制器背後的代碼（其中一個與其他類相同）：

class FormAddressExtraInfoController { 

    public function __construct(FormFactoryInterface $formFactory, EntityManager $em) { 
     $this->formFactory = $formFactory; 
     $this->em = $em; 
    } 

    private function getEntity($id) { 
     $entity = new AddressExtraInfo(); 

     try { 
      if (isset($id)) { 
       $entity = $this->em->getRepository("CommonBundle:AddressExtraInfo")->find($id); 
      } 
     } catch (\Exception $e) { 

     } 

     return $entity; 
    } 

    public function getAction($id = null) { 
     $entity = $this->getEntity($id); 
     $form = $this->formFactory->create(new AddressExtraInfoType($id), $entity, array('method' => 'POST')); 
     return array('formAddressExtraInfo' => $form->createView()); 
    } 

} 

所以問題就出在這裏。在另一個控制器（\Website\FrontendBundle\Controller\sellerController.php）的束之外我想利用這段代碼來獲得$formXXX觀點：

$this->render('FrontendBundle:Seller:newSellerLayout.html.twig', array($this->get('registercompany.form')->getAction(), $this->get('address_extra_info.form')->getAction())); 

但我得到這個錯誤：

Variable "formCompany" does not exist in FrontendBundle:Seller:newCompany.html.twig at line 10

的原因是什麼？我不是傳遞值應該是驚奇，但如果我通過他們爲：

$this->render('FrontendBundle:Seller:newSellerLayout.html.twig', array('formCompany' => $this->get('registercompany.form')->getAction(), 'formAddressExtraInfo' => $this->get('address_extra_info.form')->getAction())); 

然後誤差變換成這樣：

ContextErrorException: Catchable Fatal Error: Argument 1 passed to Symfony\Component\Form\FormRenderer::renderBlock() must be an instance of Symfony\Component\Form\FormView, array given

我不知道如何解決這個問題或者我做錯了什麼？

錯誤是明確的，有意義的告訴你，它需要FormView控件實例，您已在getAction()方法即通過陣列return array('formAddressExtraInfo' => $form->createView());需要return $form->createView()

public function getAction($id = null) { 
    $entity = $this->getEntity($id); 
    $form = $this->formFactory->create(new AddressExtraInfoType($id), $entity, array('method' => 'POST')); 
    return $form->createView(); 
/*createView() is an instance of Symfony\Component\Form\FormView 
    *which symfony expects while rendering the form 
    */ 
}
