Question

我知道已经发布了类似的问题，但我无法找到解决方案...... 我的目标是拥有一个可排序的自定义列。（从我模型中的函数构建。）列正确填充，标题是可点击的，但我尝试排序时有一个SQL异常。

这是我的代码：

所以我在视图中有一个CGridView：

[code]
$dataprovider = $parametre->searchByUser($user->Id_User,'validateur');

$this->widget('zii.widgets.grid.CGridView', array(
        'id'=>'ValidIndice-grid',
        'dataProvider'=>$dataprovider,
        'rowCssClassExpression'=>'$data->color',
        'selectableRows'=>1,
        'selectionChanged'=>'function(id){ location.href = "'.$this->createUrl('Parametre/view').'/id/"+$.fn.yiiGridView.getSelection(id);}', //array('idEvent'=>$evenement->Id_Evenements),
        'htmlOptions'=>array('class'=>'grid-view mgrid_table'),

        'columns'=>array(

                array(
                        'name'=>'Libelle',
                        'header'=>'Libellé du paramètre',
                        'value'=>'$data->Libelle'
                ),
                array(                      
                        'header'=>'Nouvelle donnée?',
                        'name'=>'NewValue',
                        'value'=>'$data->NewValue',                 

                        ),
));
?>
[/code]

在我的模特中：

[code]

public  function searchByUser($idUser,$role)
    {
        $criteria=new CDbCriteria;
        $criteria->alias = 'Parametre';

        $criteria->join='LEFT JOIN Droit ON Droit.Id_Parametre  = Parametre.Id_Parametre';

        $criteria->compare('Id_Parametre',$this->Id_Parametre,true);
        $criteria->compare('Libelle',$this->Libelle,true);

             ... Other criteria ... 

        $criteria->compare('NewValue',$this->NewValue);

        $sort = new CSort();
        $sort->attributes = array(
                'NewValue'=>array(
                        'asc'=>'NewValue ASC',
                        'desc'=>'NewValue DESC',
                ),
                '*', // this adds all of the other columns as sortable
        );

        return new CActiveDataProvider($this, array(
                'criteria'=>$criteria,
                'sort'=>$sort,
        ));
    }
[/code]

并在同一模型中使用我的函数来查看是否有新值：

[code]
    public function getNewValue() //mean => hasNewValue()
    {   
        $condition = 'Id_Parametre=:IdParam AND boolValide != 1';
        $params =  array(':IdParam'=>$this->Id_Parametre);
        if(Valeur::model()->exists($condition,$params)!=null)
        {
            return true;
        }   
        else 
        {
            return false;
        }
    }
[/code]

这样，我的CGridView被正确填充，并且我的＆＃34; newValue＆＃34;列是可点击的。但是当我点击它时，我有一个sql例外，因为他找不到专栏＆new 39＆quot; newValue＆＃39;。它的逻辑，这个专栏不存在，因为它是一个函数（getNewValue）。怎么了？提前致谢！

如果需要，这是错误：

Answer 1

试试这个可行。

将表'Droit'中的'NewValue'列调用为CSort（）中的Droit.NewValue。

$sort->attributes = array(
            'NewValue'=>array(
                    'asc'=>'Droit.NewValue ASC',
                    'desc'=>'Droit.NewValue DESC',
            ),
            '*', // this adds all of the other columns as sortable
    );

Answer 2

我使用了数据表而不是CGridView＆amp;数据提供器。它更直观;简单明了;

我无法理解数据提供者中存在的所有数据及其工作原理。

在yii CGridView中的自定义字段上排序
