<?PHP $this->widget('zii.widgets.grid.CGridView', array(
    'id' => 'mails-grid',
    'dataProvider'=>$dataprovider->search(),
    'columns' => $dialog->columns(),
    'filter' => $dataprovider,
    'template' => $dialog->link()."{summary}\n{items}\n{pager}",
)); ?>

解决方法:

我有餐厅,城市,乡村和用户模型,他们之间的关系.

模型：

public function search() {
  $criteria=new CDbCriteria;
  $criteria->together = true;
  $criteria->with= array('xCountry','xCity','User');
  $criteria->compare('Id',$this->Id,true);
  $criteria->compare('Restaurant.Name',$this->Name,true);
  $criteria->addSearchCondition('xCountry.Name',$this->Country);
  $criteria->addSearchCondition('xCity.Name',$this->City);
  $criteria->compare('Zip',$this->Zip,true);
  $criteria->compare('Address',$this->Address,true);
  $criteria->compare('Description',$this->Description,true);
  $criteria->compare('Restaurant.Active',$this->Active,true);
  $criteria->addSearchCondition('User.Username',$this->Owner);
  $criteria->compare('Lat',$this->Lat);
  $criteria->compare('Lon',$this->Lon);

  return new CActiveDataProvider($this, array(
    'criteria'=>$criteria,
  ));
}

视图：

$this->widget('zii.widgets.grid.CGridView', array(
      'id'=>'restaurant-grid',
      'dataProvider'=>$model->search(),
      'filter'=>$model,
      'columns'=>array(
        'Id',
        'Name',
        'Zip',
        'Address',
        'Active',
        array(
          'name' => 'User.Username',
          'header' => 'Username',
          'filter' => CHtml::activeTextField($model, 'Owner'),
          'value' => '$data->User->Username',
            ),
        array(
          'name' => 'xCountry.Name',
          'header' => 'Country',
          'filter' => CHtml::activeTextField($model, 'Country'),
          'value' => '$data->xCountry->Name',
            ),
        array(
          'name' => 'xCity.Name',
          'header' => 'City',
          'filter' => CHtml::activeTextField($model, 'City'),
          'value' => '$data->xCity->Name',
            ),
        array(
        'class'=>'CButtonColumn',
        ),
      ),
    ));

我希望这可以帮到你.

更新：

如果您尝试这样的事情怎么办：

...
'columns'=>array(
  'mailTemplate.name',
  'sendDate',
  'mailTemplate.subject',
  'client.email',
  ...

更新#2：

准备好自己这会有点脏.

假设我们有两个类,A和B. B属于A.
B有一个属性,让我们说“颜色”,我们想在我们列出“A”的网格中显示它.

您要做的第一件事是,手动为数据提供程序类创建属性(什么是“A”).
此属性将为“colorOfB”,因此您必须添加“public $colorOfB;”你的模特A.

添加此属性的条件：

$criteria->compare('B.color',$this->colorOfB,true);

将列添加到网格：

array(
  'name' => 'B.color',
  'header' => 'Color of B',
  'filter' => CHtml::activeTextField($model, 'colorOfB'),
  'value' => '$data->B->color'),

最后一件事是在A的控制器中手动设置此属性：

$modelA = new A('search');
$modelA->colorOfB = $_GET['A']['colorOfB'];
