CGridView单元中的renderPartial

Question

我想在CGridView的单元格中呈现一个php视图文件。

因此，我编写了以下代码：

$this->widget('zii.widgets.grid.CGridView', array(
  'dataProvider'=>$dataProvider,
  'columns'=>array(
      array(
          'value'=>array($this, 'renderPartial("_lineProblems")')
      ))));

但是我得到了这个错误：

BookController and its behaviors do not have a method or closure named "renderPartial('_lineProblems' )".

堆栈跟踪将这显示为问题：

call_user_func_array(array(BookController, "renderPartial('_lineProblems' )"), array("data" => line, "row" => 0, 0 => CDataColumn))

我不明白这个错误。$this是BookController的实例，BookController是CController的子级。

在另一个Yii programmer的帮助下找到了解决方案

$controller = $this;

$this->widget('zii.widgets.grid.CGridView', array(
  'dataProvider'=>$dataProvider,
  'columns'=>array(
      array(
          'name'=>'errors',
          'value'=>function($data, $row) use ($controller){
                return $controller->renderPartial('_lineProblems', array('errors'=>$data->errors), true);
          }
      )
  ),
));
