Question

I have a model Reporter.

public function relations() {
    return array(
        'video' => array(self::HAS_MANY, 'Video', 'reporter_id'),
    );
}

I have a mysql query for Reporter->search() method:

SELECT t.*, COUNT(t1.id) AS 'reports'
FROM reporter AS t
LEFT JOIN video AS t1 ON t.id = t1.reporter_id  
GROUP BY t.id
ORDER BY t.name

How can it be written in terms of CDbCriteria to use with CActiveDataProvider?

Answer 1

To write that query into the criteria for a CActiveDataProvider you’ll need to set the following properties from CDbCriteria:

select,
join,
group, and
order.

You can then set them while creating a new CActiveDataProvider object like so:

$dataProvider=new CActiveDataProvider('Reporter', array(
    'criteria'=>array(
        'select'=>'`t`.*, count(`t1`.`id`) as `reports`',
        'join'=>'LEFT JOIN `video` AS `t1` ON `t`.`id` = `t1`.`reporter_id`',
        'group'=>'`t`.`id`',
        'order'=>'`t`.`name`',
    ),
));

The whole list of properties and methods that you can use with CDbCriteria can be found here: CDbCriteria Class Reference
