Question

以下是我的查询如何在yii中放置视图，模型，控制器中的代码

select productid, count(*) from fc_member group by productid order by count(*)desc LIMIT 3

请让我知道我是新手我确实尝试过，但不知道如何以及它是什么:(

控制器

public function actiondsplayproduct()
{
    $model=new Member;
    $dataProvider=new CActiveDataProvider('$model',
            array(
                    'criteria'=>array(
                            'select'=>'productid, COUNT( * )as Cproductid',
                            'from'=>'fc_member',
                            'group'=>'productid',
                            'order'=>'COUNT( * ) ',

                    ),
            )
    );
    $this->render('dsplayproduct',array(
            'dataProvider'=>$dataProvider,
    ));


    //$this->render('dsplayproduct',array('model'=>$model));
}

查看

$this->widget('zii.widgets.grid.CGridView', array(
        'dataProvider'=> $dataProvider,
        'filter'=>$model,
        'columns'=>array(
                'productid',
                'Cproductid',
        )
));

并且还得到以下错误

PHP警告

include($model.php) [<a href='function.include'>function.include</a>]: failed to open stream: No such file or directory

请让我知道我是新手

我确实尝试但后来不知道它是怎么回事:(

跟随r d更改

   model

 `public function top_selling_products() {

   $criteria = new CDbCriteria;
     $criteria->select = 'productid ,  count(*) as pid_count';

     $criteria->from='fc_member';
  $criteria->group = 'productid';
     $criteria->order = 'pid_count desc';


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

  controoler
    `
  public function actiondsplayproduct()
  {

$dataProvider=new CActiveDataProvider('Member');
$this->render('dsplayproduct',array(
    'dataProvider'=>$dataProvider,
));

} view $ this-＆gt; widget（'zii.widgets.grid.CGridView'，array（

   'dataProvider'=>Member::model()->top_selling_products(),
  'enablePagination' => false,
        'columns'=>array(
'pid',
  'pid_count',
    array(
    'class'=>'CButtonColumn',
      ),
       ),
 )); `

但是我得到了以下错误

未定义属性“CDbCriteria.from”。

Plz让我现在我错了

Answer 1

我认为它不是你想要放入$model类的字符串CActiveDataProvider ...

所以，它不是

CActiveDataProvider('$model', ...

但是

CActiveDataProvider('model', ...

或者

CActiveDataProvider($model, ...

Answer 2

错误说你没有＆＃34; $ model.php＆＃34;文件 - 因此您必须为模型文件添加有效和现有名称。

例如：

new CActiveDataProvider('model', ...
