When you come to create the form Yii will automatically create validation rules based on your table structure - so in the case below Yii won't validate a null title or a title which is more than 5 characters.

~~~
CREATE TABLE tbl_details (
     uniq VARCHAR(20) NOT NULL PRIMARY KEY,     date_in date DEFAULT NULL,     time_in time DEFAULT NULL,     title VARCHAR(5) NOT NULL,      first VARCHAR(30) DEFAULT NULL,     last VARCHAR(30) DEFAULT NULL,      email VARCHAR(60) DEFAULT NULL
);
~~~* Lists all models.
*/

 
public function actionIndex()         {              $model=new Details;              if(isset($_POST['Details']))             {   
 
                {   
 
$model->attributes=$_POST['Details'];               if ($model->save())          { print "Your model has been saved";die();   }
 
         die();  
 
}
 
    }  
 
$this->render('details_form',array(             'model'=>$model,         )); 
 
        )); 
 
}
