php - Displaying attributes from another model using CGRIDVIEW -

i have 2 tables/models:

tmp1

• header
• questiontext

tmp2

• header
• part
• outof

i'm trying display columns: header, questiontext, part, outof
in single cgridview.

in tmp1 model:

public function relations()   {     return array(                  'tmp2s' => array(self::has_many, 'tmp2', 'header'),                 );   }   

in tmp2 model:

public function relations() {       return array(           'header' => array(self::belongs_to, 'tmp1', 'header'),       );   }   

controller:

 public function actionreviewall()       {           $tmp1 = new tmp1('search');                   $tmp1->unsetattributes();            if(isset($_get['tmp1'])){               $model->attributes=$_get['tmp1'];           }            $this->render('reviewall',array(                   'tmp1'=>$tmp1,           ));       }   

view:

$this->widget('zii.widgets.grid.cgridview', array(     'id'=>'tmp-grid',     'dataprovider'=>$tmp1->search(),     'filter'=>$tmp1,     'columns'=>array(         'header',         'questiontext',         array(             'name' => 'tmp2.outof',             'value' => '$data->tmp2[0].outof',             'type' => 'raw'         ),      ),  )); ?> 

error:

property "tmp1.tmp2" not defined.

any appreciated

you have sintax error:

tmp1.tmp2 = tmp1.tmp2s

the relation alias 's'. "tmp2s".

    $this->widget('zii.widgets.grid.cgridview', array(     'id'=>'tmp-grid',     'dataprovider'=>$tmp1->search(),     'filter'=>$tmp1,     'columns'=>array(         'header',         'questiontext',         'tmp2s.part',         'tmp2s.outof',     ),  )); ?> 

but trying show 'self::has_many' relationship, can't show on normal cgridview widget...
