CakePHP Custom Query Paginator - cakephp

Question

Currently I am got 2 page require Pagination.
I also do some research such as setting or at model do the custom Query. However the Paginator can't work.
Now I am trying add custom query paginator to index page. (I need to use group by)
I also trying to add custom query paginator to view page. ( I need base on the id)
Controller:
public function index() {
$setting = $this->Paginator->settings = $this->Report->query('
SELECT SUM( seats_occupied ) as totalOccupied, event_date, r.event_date_id
FROM reports r, event_dates ed WHERE r.event_date_id = ed.event_date_id
GROUP BY event_date
');
debug($this->Paginator->paginate());
$this->set('showDate',$setting);
}
public function view($eventDateId = null){
if (!$eventDateId) {
throw new NotFoundException(__('Invalid post'));
}
// We only want single post so we use FindById.
$post = $this->Report->findAllByEventDateId($eventDateId);
// debug($this->Paginator->paginate($post));
if (!$post) {
//if user requet fypcakephp/view without id will throw the not found except
throw new NotFoundException(__('Invalid post'));
}
$setting = $this->Paginator->settings = $this->Report->query("
SELECT *
FROM reports where event_date_id='$eventDateId' order by period asc
");
//array( 'conditions' => array( 'event_date_id' => $post));
debug($setting);
$this->set('viewData', $setting); //Then send this data
}
I also got try do at model custom Query however If I do this way , my view can't get the data I want due to I using "Group By".
//To custom the paginate display the thing you want. (This one return)
//public function paginate($conditions, $fields, $order, $limit, $page = 1,
// $recursive = null, $extra = array())
//{
// $recursive = 0;
//
// // Mandatory to have
// $this->useTable = false;
// $sql = '';
//
//
// $sql .= " select * from reports;";
//
//
//
// $sql .= " SELECT SUM( seats_occupied ) as totalOccupied, event_date,r.event_date_id
// FROM reports r, event_dates ed WHERE r.event_date_id = ed.event_date_id
// GROUP BY event_date; ";
//
//
//
// // Adding LIMIT Clause
//// $sql .= (($page - 1) * $limit) . ', ' . $limit;
//
// $results = $this->query($sql);
//
// return $results;
//}
//public function paginateCount($conditions = null, $recursive = 0, $extra = array())
//{
// $sql = '';
//
// $sql .= "SELECT SUM( seats_occupied ) as totalOccupied, event_date ,r.event_date_id
// FROM reports r, event_dates ed WHERE r.event_date_id = ed.event_date_id
// GROUP BY event_date";
//
// $this->recursive = $recursive;
//
// $results = $this->query($sql);
//
// return count($results);
//}
