Hi again hameedhamdani

The
// Subscriber

'assignments' => array(self::HAS_MANY, 'Assignment', phone_number_id),

// Assignment

'subscriber' => array(self::BELONG_TO, 'Subscriber', phone_number_id),
have sense only if an subscriber has a parent subscriber or assignments too,

I think in your case you needn’t it

To make your relations AR sense-clear check in an action (like view or index) with var_dump the primary model content (like related models and id’s)

Do not try solve the problem relations and cgridview at once, but step by step

Hi Sir,

Again welcome…plz carry on Steps…what next?

Thanks Sir,

i used same relations as u described but same error




 		Trying to get property of non-object	


 	 		C:\wamp\www\yii\framework\base\CComponent.php(607) : eval()'d code(1)

in cgridview code is




array(

'header'=>Assignment::model()->getAttributeLabel('group_id'),	//column header

'value'=>'($data->getRelated(\'assignments\')=== null)?"No related assignment  Exist":$data->getRelated(\'assignments\')->group_id', //column name, php expression


'type'=>'raw',

),

What is the next step>

The $data->getRelated(\‘assignments\’) has more one records due to HAS_MANY relation

replace

$data->getRelated(\‘assignments\’)->group_id

with

array_pop($data->getRelated(\‘assignmentrel\’))->group_id’, to get the first one

If you want to show all group_id you can to with another way
