| モデルに定義したアソシエーションが効かない。 |
| バージョン : CakePHP 2.7.0 |
| 以下３つのモデルを使います。 |
| ・Post |
| ・Tag |
| ・PostsTag |
| PostとTagはそれぞれHABTMの関係になっています。 |
| Tagで検索する処理を書きたいのですが、Postはbelongsto tagではないので、Tagをwhereに指定するとそんなカラムないと怒られます。 |
| そのため、中間テーブルをPostとTagにbelongstoさせて、以下の通りにしていますが、TagとPostテーブルはjoinされません。 |
| 今まではpublic $belongsTo = array()でモデルを指定すればjoinしていたのですが。。。 |
| もしお分りになる方がいらっしゃれば助けていただければと思います。 |
| ＜PostsController＞ |
| public function tag($tag = null, $id = null) { |
| $this->loadModel('PostsTag'); |
| $this->set('posts', $this->PostsTag->find('all', |
| array( |
| 'conditions' => array('Tag.tag' => $tag), |
| 'limit' => '30', |
| ) |
| ) |
| ); |
| } |
| ＜PostsTag＞ |
| class PostsTag extends AppModel { |
| public $name = 'PostsTag'; |
| public $belongsTo = array( |
| 'Tag' => array( |
| 'className' => 'Tag', |
| 'foreignKey' => 'tag_id', |
| 'conditions' => '', |
| 'fields' => '', |
| 'order' => '' |
| ), |
| 'Post' => array( |
| 'className' => 'Post', |
| 'foreignKey' => 'post_id', |
| 'conditions' => '', |
| 'fields' => '', |
| 'order' => '' |
| ) |
| ); |
| } |
| ちなみにデバッグでPostsTagを見ると以下のようになります。 |
| debug($this->PostsTag); |
| object(AppModel) { |
| useDbConfig => 'default' |
