Zend 2模块.用模型/控制器未检索记录的约束

Question

我正在学习Zend 2，并且有一个我似乎无法解决的问题。我确定这很简单，但我无法确定。我要做的就是按state_id列表记录，还可以从列表中查看记录。仅显示一个观点。当我提出/blog/view/1时，我会收到一条消息，上面写着：找不到第0。这与当前链接一起显示，如果我取消/1。因此，它甚至没有查看记录号。我怀疑这可能是路由，但不确定。谢谢这就是我所拥有的：

Module.config
'router' => array(
  'routes' => array(      
      'blog' => array(        
        'type'    => 'Literal',
        'options' => array(
            'route'    => '/Blog',
            'defaults' => array (
              'module'     => 'Blog',
              'controller' => 'BlogController',
              'action'     => 'index',
            ), // defaults end 
        ), // options end           
        'may_terminate' => true,
            'child_routes' => array(
                'list' => array(
                    'type'    => 'segment',
                    'options' => array(
                        'route'    => '/list[/:state_id]',
                        'defaults' => array (
                            'action'     => 'list',
                        ), //defaults end
                        'constraints' => array(
                            'state_id'     => '[0-9]+',
                        ) // constraints end
                    ), // options end
                ), // view end
                'view' => array(
                    'type'    => 'segment',
                    'options' => array(
                        'route'    => '/view[/:post_id]',
                        'defaults' => array(
                            'action'     => 'view',
                        ), // defaults end
                        'constraints' => array(
                        'post_id'     => '[0-9]+',
                        ) // constraints end
                    ), // options end
                ),  // post end 
            ) // child route end            
        ), // blog end
    ) // routes end       
) // router end
); // return array end

模型：posttable.php

 public function getPosts($post_id)
 {
   $post_id  = (int) $post_id;
   $rowset = $this->tableGateway->select(array('post_id' => $post_id));
   $row = $rowset->current();
   if (!$row) {
       throw new Exception("Could not find row $post_id");
   }
   return $row;
 }

查看：

<h1><?php echo $this->escapeHtml($title); ?></h1>
<table class="table">
<tr>
   <th>Title</th>
   <th>View</th>
   <th>Comments</th>
   <th>Post Date</th>
</tr>
<?php foreach ($list as $posts) : ?>
<tr>
  <td><?php echo $this->escapeHtml($posts->post_title);?></td>
  <td><?php echo $this->escapeHtml($posts->num_views);?></td>
  <td><?php echo $this->escapeHtml($posts->num_comments);?></td>
  <td><?php echo $this->escapeHtml($posts->post_date);?></td>
</tr>
<?php endforeach; ?>

编辑：06/06/2016添加了查看操作。

 public function viewAction()
 {
    return new ViewModel(array(
     'list' => $this->getPostsTable()->getPosts(),
    )); 
 }

也是GetPosttable动作：

 public function getPostsTable()
 {   
     if (!$this->postsTable) {
        $sm = $this->getServiceLocator();
        $this->postsTable = $sm->get('BlogModelPostsTable');
     }
     return $this->postsTable;
 }

您需要在控制器中的getPosts()方法中提供邮政ID。以下是根据您的PostTable的getPosts()方法。

public function viewAction()
{
    // Get the post ID from the route, /Blog/view/1
    $post_id = $this->params()->fromRoute('post_id');
    $list = $this->getPostsTable()->getPosts($post_id);
    $view = new ViewModel(array(
        'list' => $list,
    ));
    return $view;
}
