Display Crud Entries Just By User

I’m trying to display the CRUD Documents by the current user. I’ve been looking at CDbCriteria and tried adding it to actionIndex():

    public function actionIndex()


        $user_id = Yii::app()->user->getId();

        $criteria=new CDbCriteria;



        $dataProvider=new CActiveDataProvider('Document');



            'criteria' => $criteria,



…however it continues to show all the Documents rather than just the ones by the current user. I’m not sure what I’m doing wrong.

Basically all I want to do is SELECT * FROM document WHERE user_id=$user_id

Edit: Fixed. Removed the $criteria’s and defined the criteria in CActiveDataProvider.
