列在JTable中不显示

Question

我创建一个DataGrid与JTable中，这是我的JavaScript代码：

<script type="text/javascript"> 
    $(document).ready(function() { 
     $('#PersonTableContainer').jtable({ 
      title: 'Table of people', 
      actions: { 
       listAction: '{{ path("person_list") }}', 
       createAction: '', 
       updateAction: '', 
       deleteAction: '' 
      }, 
      fields: { 
       PersonId: { 
        key: true, 
        list: false 
       }, 
       Name: { 
        title: 'Name', 
        width: '40%' 
       }, 
       Age: { 
        title: 'Age', 
        width: '20%' 
       }, 
       PaysId: { 
        title: 'Country', 
        width: '30%' 
       } 
      } 
     }); 
    }); 
</script> 

的代码工作正常，它会显示所有信息。

____________________________ 
Name  | Age | Country 
---------------------------- 
Mohssine | 22  | France 
Saad  | 10  | USA 
____________________________ 

后，我加入这个代码：

options: '{{ path("get_countries") }}', 

来为用户显示一个组合框，当他想改变或创建一个新的记录，下面的代码：

<script type="text/javascript"> 
    $(document).ready(function() { 
     $('#PersonTableContainer').jtable({ 
      title: 'Table of people', 
      actions: { 
       listAction: '{{ path("person_list") }}', 
       createAction: '', 
       updateAction: '', 
       deleteAction: '' 
      }, 
      fields: { 
       PersonId: { 
        key: true, 
        list: false 
       }, 
       Name: { 
        title: 'Name', 
        width: '40%' 
       }, 
       Age: { 
        title: 'Age', 
        width: '20%' 
       }, 
       PaysId: { 
        title: 'Country', 
        options: '{{ path("get_countries") }}', 
        width: '30%' 
       } 
      } 
     }); 
    }); 
</script> 

PHP代码：返回国家列表的函数

public function getCountriesAction() 
    { 
     $stmt = $this->getDoctrine()->getEntityManager() 
      ->getConnection() 
      ->prepare('select country as DisplayText,id as value from countries'); 
     $stmt->execute(); 
     $countries = $stmt->fetchAll(); 

     $jTableResult = array(); 
     $jTableResult['Result'] = "OK"; 
     $jTableResult['Options'] = $countries; 
     $serializer = new Serializer(array(new GetSetMethodNormalizer()), array('json' => new JsonEncoder())); 
     $content = $serializer->encode($jTableResult, 'json'); 
     return new Response($content); 
    } 

当我显示我的数据网格时，所有的信息都在那里，除了我在代码中添加的列以外，它没有任何信息显示。

请解决方案，谢谢。

你必须改变你的函数getCountriesAction：

public function getregionsAction() 
    { 
     $stmt = $this->getDoctrine()->getEntityManager() 
      ->getConnection() 
      ->prepare('select country,id from countries'); 
     $stmt->execute(); 
     $countries= $stmt->fetchAll(); 



     foreach ($countries= as $key => $value) { 

      $eil = array(); 
      $eil["DisplayText"] = $countries[$key]['country']; 
      $eil["Value"] = $countries[$key]['id']; 
      $rows[] = $eil; 
     } 

     $jTableResult = array(); 
     $jTableResult['Result'] = "OK"; 
     $jTableResult['Options'] = $rows; 

     $serializer = new Serializer(array(new GetSetMethodNormalizer()), array('json' => new JsonEncoder())); 
     $content = $serializer->encode($jTableResult, 'json'); 
     return new Response($content); 
    }
