zend框架2无法呈现模板解析器无法解析到文件

Question

我正在学习如何使用Zend Framework2。根据网上提供的一些教程，我写了一些代码段。对我来说最重要的教程是这样的：https://github.com/psamatt/zf2-doctrine-example它涵盖了我计划编写的大部分基础知识。我坚持一个对我来说很陌生的问题。在我的摘要页面上，显示来自数据库的所有记录我有一个链接来添加新记录，编辑现有记录和删除记​​录。路由是由module.config.php覆盖：

 'router' => array(
      'routes' => array(
        'incident' => array(
          'type' => 'segment', 
          'options' => array(
            'route' => '/incident[/][:action][/:id]', 
            'constraints' => array(
              'action' => '[a-zA-Z][a-zA-Z0-9_-]*', 
              'id'  => '[0-9]+', 
            ), 
            'defaults' => array(
              'controller' => 'Helpdesk\Controller\Incident', 
              'action'  => 'index', 
            ), 
          ), 
        ), 
      ), 
    ), 

当我使用一个链接到一个新的记录（h.t.t.p：//帮助台/事件/添加）一切正常。但是，当我使用链接编辑我的记录（HTTP：//帮助台/事件/编辑/ 1 - 其中1例记录ID）我收到一个错误：

Zend\View\Renderer\PhpRenderer::render: Unable to render template "helpdesk/incident/edit"; resolver could not resolve to a file

这是我IncidentController.php ：

<?php 
namespace Helpdesk\Controller; 

use Application\Controller\EntityUsingController; 
use DoctrineModule\Stdlib\Hydrator\DoctrineObject; 
use Doctrine\ORM\EntityManager; 
use Zend\View\Model\ViewModel; 

use Helpdesk\Form\IncidentForm; 
use Helpdesk\Entity\Incident; 



class IncidentController extends EntityUsingController 
{ 

/** 
* Index action 
* 
*/ 
public function indexAction() 
{ 
    $em = $this->getEntityManager(); 

    $incidents = $em->getRepository('Helpdesk\Entity\Incident')->findAll(); 

    return new ViewModel(array(
      'incidents' => $incidents 
    )); 
} 


/** 
* Edit action 
* 
*/ 
public function editAction() 
{ 
    $incident = new Incident(); 
    if ($this->params('id') > 0) { 
     $incident = $this->getEntityManager()->getRepository('Helpdesk\Entity\Incident')->find($this->params('id')); 
    } 

    $form = new IncidentForm($this->getEntityManager()); 
    $form->bind($incident); 
    $form->setHydrator(new DoctrineObject($this->getEntityManager(),'Helpdesk\Entity\Incident')); 

    $request = $this->getRequest(); 

    if ($request->isPost()) { 
     $form->setInputFilter($incident->getInputFilter()); 
     $form->setData($request->getPost()); 
     if ($form->isValid()) { 
      $em = $this->getEntityManager(); 
      $em->persist($incident); 
      $em->flush(); 

      $this->flashMessenger()->addSuccessMessage('Incident saved'); 

      // Redirect to list of incidents 
      return $this->redirect()->toRoute('incident'); 
     } 
    } 

    return array(
      'incident' => $incident, 
      'form' => $form, 
    ); 
} 


/** 
* Add action 
* 
*/ 
public function addAction() 
{ 
    return $this->editAction(); 
} 


/** 
* Delete action 
* 
*/ 
public function deleteAction() 
{ 
    $id = (int)$this->getEvent()->getRouteMatch()->getParam('id'); 
    if (!$id) { 
     return $this->redirect()->toRoute('incident'); 
    } 

    $request = $this->getRequest(); 
    if ($request->isPost()) { 
     $del = $request->post()->get('del', 'No'); 
     if ($del == 'Yes') { 
      $id = (int)$request->post()->get('id'); 
      $incident = $this->getEntityManager()->find('Helpdesk\Entity\Incident', $id); 
      if ($incident) { 
       $this->getEntityManager()->remove($incident); 
       $this->getEntityManager()->flush(); 
      } 
     } 

     // Redirect to list of incidents 
     return $this->redirect()->toRoute('default', array(
       'controller' => 'incident', 
       'action' => 'index', 
     )); 
    } 

    return array(
      'id' => $id, 
      'incident' => $this->getEntityManager()->find('Helpdesk\Entity\Incident', $id)->getArrayCopy() 
    ); 
} 
} 

这两者有什么区别？为什么一个工作正常，而第二个产生错误？

感谢您的帮助

最有可能的helpdesk/incident/edit.phtml不存在，而添加操作是渲染现有的helpdesk/incident/add.phtml。

您可以重复使用现有的helpdesk/incident/add.phtml或创建一个新的helpdesk/incident/add.phtml。
