How can i filter a model inside my controller for CGridView and let user search it through the CGridView search?

If i filter like this




		$model=new MyObject('search');

		$model->unsetAttributes();  // clear any default values

		

		if(isset($_GET['MyObject']))

			$model->attributes=$_GET['MyObject'];

		

		$dataProvider = new CActiveDataProvider($model, array(

			

		  'criteria'=>array(

		  	"join"=>"LEFT JOIN other_table ON other_table.field=field",

			'condition'=>" other_field = ".$id." ",

			

		  ),


		  

      	));

and load the cgridview like this




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

	'id'=>'corsi-grid',

	'dataProvider'=>$corsi_frequentati[1], // $dataProvider

	'filter'=>$corsi_frequentati[0], // $model

I can’t filter it later
