38. Model へ…

39. Modelに移すときの
私的原則
各メソッドで共通の検索条件
$this->data の繰作

40. 今回の場合は
各メソッドで共通の検索条件
• user_idの絞り込み
$this->data の繰作
• user_idの付与
• FileUpload

41. user_idの絞り込み
Model::beforeFind()を使う
user_idをModelにどうやって渡す？
• Configure::write()
• Configure::read()

42. PostsController::beforeFilter()
function beforeFilter() {
� parent::beforeFilter();
� Configure::write('User.id', $this->Auth->user('id'));
}

43. PostsController::beforeFilter()
user_idを書き込み
function beforeFilter() {
� parent::beforeFilter();
� Configure::write('User.id', $this->Auth->user('id'));
}

44. Post::beforeFind()
function beforeFind($queryData) {
� $conditions = array(
� � $this->alias.'.user_id'=>Configure::read('User.id'),
� );
� $queryData['conditions'] =
� Set::merge($queryData['conditions'], $conditions);
� return $queryData;
}

45. Post::beforeFind()
user_idを読み出し
function beforeFind($queryData) {
� $conditions = array(
� � $this->alias.'.user_id'=>Configure::read('User.id'),
� );
� $queryData['conditions'] =
� Set::merge($queryData['conditions'], $conditions);
� return $queryData;
}

46. Post::beforeFind()
user_idを読み出し
function beforeFind($queryData) {
� $conditions = array(
� � $this->alias.'.user_id'=>Configure::read('User.id'),
� );
� $queryData['conditions'] =
� Set::merge($queryData['conditions'], $conditions);
� return $queryData;
}
conditionsは多次元配列になりえる
ので、Set::merge()を使う

47. PostsController::index()
� function index() {
� � $this->paginate = array(
� � � 'conditions'=>array(
� � � � 'Post.user_id'=>$this->Auth->user('id'),
� � � ),
� � );
� � $this->Post->recursive = 0;
� � $this->set('posts', $this->paginate());
� }

48. PostsController::index()
� function index() {
� � $this->paginate = array(
� � � 'conditions'=>array(
� � � � 'Post.user_id'=>$this->Auth->user('id'),
� � � ),
� � );
� � $this->Post->recursive = 0;
� � $this->set('posts', $this->paginate());
� }

49. PostsController::index()
� function index() {
� � $this->paginate = array(
� � � 'conditions'=>array(
� � � � 'Post.user_id'=>$this->Auth->user('id'),
� � � ),
� � );
� � $this->Post->recursive = 0;
� � $this->set('posts', $this->paginate());
� }

50. PostsController::view()
function view($id = null) {
� $conditions = array(
� � 'Post.id'=>$id,
� � 'Post.user_id'=>$this->Auth->user('id'),
� );
� $post = $this->Post->find('first', compact('conditions'));
� if (!$post) {
� � $this->Session->setFlash(__('Invalid Post.', true));

90. AppController へ…

91. AppControllerに移すときの
私的原則
フックメソッドでの処理
2つ以上のControllerで共通の処理

92. 今回の場合は
フックメソッドでの処理
• 既にComponentに移しているので、
なし
2つ以上のControllerで共通の処理
• 今回の例では、Controllerが一つしか
ないが、同様の処理（例えばリンク集
とか）のControllerがあるとして

93. ポイント1
PostController
$this->Post->save()
AppController
$this->{$this->modelClass}->save()

94. ポイント2
PostController
$this->set(‘posts’, $this->paginate());
AppController
$name = Inflector::pluralize(
Inflector::variable($this->modelClass));
$this->set($name, $this->paginate());

again.', true));
� � }
� } else {
� � $this->data = $post;
� }
}

103. AppController::delete()
function delete($id = null) {
� $conditions = array(
� � $this->modelClass.'.id'=>$id,
� );
� $data = $this->{$this->modelClass}->find('first', compact('conditions'));
� if (!$data) {

true));
� � $this->redirect(array('action'=>'index'));

� if ($this->{$this->modelClass}->del($id)) {
� � $this->Session->setFlash(__($this->modelClass.' deleted', true));
� � $this->redirect(array('action'=>'index'));
� }
}

104. Componentsを
AppControllerへ
PostController
class PostController extends AppController {
� var $components = array('Account');
AppController
class AppController extends Controller {
� var $components = array('Auth', 'Account');

105. <?php
class PostsController extends AppController {
var $name = 'Posts';
var $components = array(‘Account’);
function index() {
$this->Post->recursive = 0;
$this->set('posts', $this->paginate());
}
function view($id = null) {
$conditions = array(
'Post.id'=>$id,
);
$post = $this->Post->find('first', compact('conditions'));
if (!$post) {
$this->Session->setFlash(__('Invalid Post.', true));
$this->redirect(array('action'=>'index'));
}
$this->set(compact('post'));
}
function add() {
if (!empty($this->data)) {
$this->Post->create();
if ($this->Post->save($this->data)) {
$this->Session->setFlash(__('The Post has been saved', true));
$this->redirect(array('action'=>'index'));
} else {
$this->Session->setFlash(__('The Post could not be saved. Please, try again.', true));
}
}
}
function edit($id = null) {
$conditions = array(
'Post.id'=>$id,
);
$post = $this->Post->find('first', compact('conditions'));
if (!$post) {
$this->Session->setFlash(__('Invalid Post', true));
$this->redirect(array('action'=>'index'));
}
if (!empty($this->data)) {
if ($this->Post->save($this->data)) {
$this->Session->setFlash(__('The Post has been saved', true));
$this->redirect(array('action'=>'index'));
} else {
$this->Session->setFlash(__('The Post could not be saved. Please, try again.', true));
}
} else {
$this->data = $post;
}
}
function delete($id = null) {
$conditions = array(
'Post.id'=>$id,
);
$post = $this->Post->find('first', compact('conditions'));
if (!$post) {
$this->Session->setFlash(__('Invalid id for Post', true));
$this->redirect(array('action'=>'index'));
}
if ($this->Post->del($id)) {
$this->Session->setFlash(__('Post deleted', true));
$this->redirect(array('action'=>'index'));
}
}
}
?>

106. これぞ究極！？
<?php
class PostsController extends AppController {
� var $name = 'Posts';
}
?>

107. おまけ
Modelのフックメソッドへ移した処理
は、そのままBehavior化できる。

108. UploadBehavior
class UploadBehavior extends ModelBehavior {
function beforeSave(&$model, $options = array()) {
if (!$model->data[$model->alias]['image']['error']) {
$filename = low($model->alias).DS.$model-
>data[$model->alias]['image']['name'];
move_uploaded_file(
$model->data[$model->alias]['image']['tmp_name'],
WWW_ROOT.'img'.DS.$filename);
$model->data[$model->alias]['image'] = $filename;
} else {
unset($model->data[$model->alias]['image']);
}
return true;
}
}

109. Post
class Post extends AppModel {
var $name = 'Post';
var $actsAs = array('Upload');

110. Post
class Post extends AppModel {
var $name = 'Post';
var $actsAs = array('Upload');

これを見て、Upload処理は
Behaviorがいいと思った

119. 英語だけれど…
コードが読めればOK！
怖がらずに目を通してみよう！

121. リファクタリングを考える時期
メソッドのパラメータが多くなった時
ひとつのメソッドが多機能になってしまった時
同じようなコードがいくつも存在している時
名前の付け方が悪い時
あるべき場所（階層）にあるべきコードを書く

122. 多くはメソッドについて語られているが、
メソッドをクラスに置き換えても
同じ事がいえる

123. リファクタリングを考える時期
クラスのメソッドが多くなった時
ひとつのクラスが多機能になってしまった時
同じようなコードがいくつも存在している時
名前の付け方が悪い時
あるべき場所（階層）にあるべきコードを書く
