I my general model classes




class Category extends CActiveRecord

{

	public function tableName()

	{

		return '{{category}}';

	}

...



I my using models




class JTCategory extends Category{ ...



and I use these codes to run my models.




$model = new JTContentbank('getdatagrid');

//or
