検索とPaginationとHABTM
で、さらにやっかいなのが、ここに「好きな物」のチェックボックスの複数選択検索を入れる場合です。
HABTMの関連テーブルですね。
一体どうすりゃいいんでしょうか。ということで相当悩みました。
結論としては、一旦その「好きな物」を選択している会員のIDを全部取り出して、そいつを条件に入れちゃえばいいんじゃなかろうかと。
クエリーのイメージはこんな感じ。
SELECT m.id FROM members m WHERE m.id IN
(SELECT member_id FROM members_favorites mf WHERE mf.favorite_id IN (1,2));
つまり()内のSELECTの部分をあらかじめデータ取得しておけばいいと。
ということでこうなった。
$fid = $this->Member->MembersFavorite->find('list', array(
'order'=>array('MembersFavorite.member_id DESC'),
'group'=>array('MembersFavorite.member_id'),
'fields' => array('MembersFavorite.member_id'),
'conditions' => array('MembersFavorite.favorite_id' => $favorite_id)
));
$conditions = array("Member.id" => $fid);
$data = $this->paginate('Member', $conditions);
これは上記ではIN ()の中はSELECT文になっているが、CakePHPの文法だとそれは入らないようなので、実際に配列が入る。こんな感じになる。
SELECT `MembersFavorite`.`id`, `MembersFavorite`.`member_id`
FROM `members_favorites` AS `MembersFavorite`
WHERE `MembersFavorite`.`favorite_id` IN (1, 2, 3)
GROUP BY `MembersFavorite`.`member_id`
ORDER BY `MembersFavorite`.`member_id` DESC
最終的にこうなりました。
