Display Select Value Of Dataprovider In Cgridview

Yii 1.1 General Discussion

Hi,

In dataprovider, I have a “sum(t.status=“accept”) as acceptstatus” and I want the result of acceptstatus to be displayed as a “value” attribute in the array of the column of the cgridview just like the value for project as shown below (eg. ‘value’=>’$data->projects->project_title’).

How am I able to do so?

Below is my codes:

DataProvider used for CGridView:




$dataProvider=new CActiveDataProvider('Approval', array(

	'criteria'=>array(

	        'join'=>'LEFT JOIN project ON t.project_id=project.project_id',

		'group'=>'t.project_id',

		'select'=>'t.project_id, sum(t.status="accept") as acceptstatus, sum(t.status="reject" as rejectstatus',	

	),		

));

CGridView:




$this->widget('zii.widgets.grid.CGridView', array(

	'dataProvider'=>$dataProvider,

	'columns'=>array(

		array(

			'header' => 'Project',

			'name'=>'project_title',

			'value'=>'$data->projects->project_title',		

		),

	),

));

Dear Friend,

The following are my suggestions.

Kindly check the query in PhpMyAdmin and ensure that it displays what you intend.

And each row corresponds to the parent table.

Then add the acceptStatus as a virtual attribute to AR model.

Add a rule to make it safe.That may be helpful when you decide to filter the records based on this

relational attribute.




class Approval extends CActiveRecord

{

   public $acceptStatus;


   public function rules()

     {

        return array(


                   array('acceptStatus','safe','on'=>'search'),

                   );

     }

}

Set the together property to true in CDbcriteria.




$dataProvider=new CActiveDataProvider('Approval', array(

        'criteria'=>array(

                'join'=>'LEFT JOIN project ON t.project_id=project.project_id',

                'together'=>true,

                'group'=>'t.project_id',

                'select'=>'t.project_id, sum(t.status="accept") as acceptstatus, sum(t.status="reject" as rejectstatus',        

        ),              

));

Then you make a column for acceptStatus in admin.php in the following way.




    array(

		'name'=>'acceptStatus',

		'value'=>'$data->acceptStatus',

	 ),

I hope it is helpful.

Regards.
