Overview

version3 と違い古いシステムでの利用が想定される。PHPのバージョン新しめの機能 ( array() -> [] ) とかは使わないほうが無難。ORMで取得するのが連想配列だったりなかなか負の遺産だけどCakePHPの稼働バージョンで一番多いのはこいつ。

セッションタイムアウトの設定

Configure::write('Session', array(
    'defaults' => 'php',
    'timeout' => 2160, // 36 hours

        'session.gc_maxlifetime' => 129600 // 36 hours - こいつを timeout より長くしないと意味ない
    )
));

recursive 2 から必要モデルだけ contain で取得

https://book.cakephp.org/2.0/ja/core-libraries/behaviors/containable.html

// Contain Sample
    $this->Seat->Behaviors->attach('Containable');
    $seats = $this->Seat->find('all', array(
      'contain'    => array('Event', 'Seat', 'Student', 'SeatVote' => array('Company')),
      'conditions' => array('Seat.event_id' => $event_id),
      'order'      => array('Seat.position' => 'asc'),
      'recursive'  => 2,
    ));

別モデル呼び出しは２パターン

このコントローラのどこでも使うよ : public $uses = array('Model1, 'Model2); この処理でしか使わないよ : $this->loadModel('Model1'); $this->loadModel() のが早いけど使いすぎると依存関係がごちゃる。複数のモデルと連携するコントローラクラスなのか、特定エンティティ（モデル）に特化したコントローラなのか設計段階で決めておくべき。

Chromeだと target="_blank" リンクでログアウトしちゃう

IEとかなら大丈夫。セキュリティ頑張るブラウザだとNGのよう。 以下でsessionのAgentチェックを無効にすると別タブログインOKに。

// core.php
  Configure::write('Session.checkAgent', false);

バーチャルフィールドで独自カラム作成

as みたいなやつ http://qiita.com/kazu56/items/82e049118a70a735fdc7

$this->request->dataの存在確認はdata()でやれ

if($this->request->data['User']['name']) だと 空値で notice 。isset() と組み合わせると冗長になるので data() メソッドを使う if ($this->request->data('User.name')) でアクセスすると存在しない場合にエラーにならないので便利。

パスワードハッシャ

AuthComponent::password() でOK

booleanはtinyint(1)なのでフォームでも0, 1 で

booleanのフォームインプットの値が true , false ではじかれた...?←未検証

find()で重複回避 DISTINCT

'fields'=>array('DISTINCT table.id'....); 上記のようにfieldsオプションの中で重複削除の基準になるカラムを指定してあげれば返り値 $query とかには重複したものは入らなくなる。ちなみにfieldsの先頭に書かないとエラー。 http://wataame.sumomo.ne.jp/archives/1235 また、find('count')のオプションでDISTINCTを使う場合、fieldsに配列で他の指定をするとアウト。http://book.cakephp.org/2.0/ja/models/retrieving-your-data.html#find-count

モデルのプライマリーキーを[id]から別カラムへ

// 規約通りでない（くそみたいな）DB構成のときにキーの再設定が可能
public $primaryKey = 'no';
//複数指定するといみわからんくなる
public $primaryKey = array('id','no');  

Paginationで用いられるクエリ取得

https://teratail.com/questions/10090 page:2 とかは $this->params['named']['page'] にいるよ

Paginator + JOINS

public $pagenate = array('諸々'); で設定しろってマニュアルに書いてあるくせにきかねえぞこらってときはコンポーネントロード時に配列でオプション渡したれ。そもそもControllerに定義した$pagenateにはアクセスしていない。$pagenateの設定を反映させるには、コンポーネントコンストラクタの引数に渡す／コンポーネントのインスタンスの内部変数書き換え（多分 $this->Paginator->settings=array() だね）／リクエスト時にパラメータとして渡す。https://blog.doizaki.com/entry/2015/04/21/001600

ShellClass - バッチ処理

バッチ非同期処理＋ポーリング

大量の DB データ（数十万件～）を取得してプログラムのメモリに格納してごにょるようなケースでは、データ量によっては「メモリ不足で落ちて」しまう。これについて一度に数千件ずつ取得するようなループを組み対処すると、今度はある一定量を超えた段階でブラウザが「サーバからの応答なし＝タイムアウト」で落ちてしまう。このような 絞り込みを行った上で数万に達するようなテーブルを扱う 場合にはサーバサイドでタスクを「DBアクセス→データ取得」「待機ページ→データ取得完了後に出力ページ」のように２つに分割し PHPで非同期処理を行う 必要がある。以下サンプルコード。

Sample: FugeExportShell

App::uses('AppShell', 'Console/Command');
App::uses('User', 'Model');

/**
 * FugeExportShell
 * @see           https://goo.gl/grcoHk
 * @package       app.Console.Command
 */
class FugeExportShell extends AppShell {
  public $uses = array('User');
  
  /**
   * test method
   * @param mix $args
   * @return mix $args
   */
  public function hello() {
    $this->out('hello, world.');  //stdout
  }

  /**
   * main: called default method by exec() 
   * get huge data using with splitting query by loop
   */
  public function main() {
    ini_set('memory_limit', -1);
    set_time_limit(0);
    $args   = unserialize($this->args[0]);
    $tmpfile = $args['tmpfile'];
    $params = $args['params'];
    $count = $this->DenpyoTbl->find('count', $params);
    $limit = 5000;  // get records number per loop
    $loop  = ceil($count / $limit); 
    for ($i = 0; $i < $loop; $i++){
      $offset = $limit * $i;
      $paramsWithOffset = $params;
      $paramsWithOffset += array('limit' => $limit, 'offset' => $offset);
      $rows = $this->User->find('all', $paramsWithOffset);
      foreach ((array)$rows as $row) $results[] = $row;
      if ($i > 0 && !file_exists(ROOT . DS . APP_DIR . DS .'tmp' . DS . $tmpfile.'__progress.txt')) exit;
      $fp_progress = fopen(ROOT . DS . APP_DIR . DS .'tmp' . DS . $tmpfile.'__progress.txt', 'w');
      fprintf($fp_progress, round((count($query)/$count * 100), 1));
      fclose($fp_progress);
    }
    $serializedResults = serialize($results);
    $fp_results = fopen(ROOT . DS . APP_DIR . DS .'tmp' . DS . $tmpfile.'.txt', 'w');
    fprintf($fp_results, $serializedResults);
    fclose($fp_results);
    exit;
  }

}

Sample: ExportController

public function async(){
  $this->autoLayout = false;
  $this->autoRender = false;
  $params = [/* something */];
  $tmpfile = 'tmpfile';
  $token = session_id();
  $querystring = http_build_query(compact('tmpfile', 'token'));
  $args = serialize(compact('tmpfile', 'params'));

  // running async process by shell (FugeExportShell)
  exec(ROOT.DS.APP_DIR.DS.'Console'.DS."cake fuge_export > /dev/null main '{$args}' &");
  echo "
    <script>

Cake1.xからの2.xへの移行

公式のアップグレードガイドを参考にしつつ https://goo.gl/FDscWi 大体のプロジェクトでは規約をちょい破ってるのでそこを手作業でかばあするhttps://goo.gl/cbrba5

1. 不要ファイル殺す
2. プラグインの対応チェック

• composerにだいたい代替R
• 優先度の見極め

1. ディレクトリ構成の調整
2. 3に伴う index.php なんかの調整
3. 公式ガイド参考に2系のコアを設置
4. upgradeシェル ぶったたく

• ソース内の命名規則調整してくれる
• 廃止関数の置き換えしてくれる
• ファイル名は手動ぽい？
• あとソースの調整も漏れが結構ある？

1. コアファイル移動(5)に伴う index.php なんかの調整
2. 自動調整（シェル）できなかった箇所を手作業でなおす

• $form-> などコンポーネント全て $this->Form などへ
• 全廃止APIの書き換え $this->Auth->user(); → $this->Auth->login();
• 自作Component調整
  • ロード順序別メソッドはやす initialize() とか
  • オートロード規約に従っている → App::uses() で読む
  • オートロード規約に従っていない → App::import() で読む
• 自作 Helper, Behavior も調整必要
• $this->data > $this->request->data
• $this->params['url']['url'] > $this->request->url
• $this->params['contoller'] > $this->request->controller
• $this->params['action'] or $this->action > $this->request->action
• $this->params['pass'] or $this->passedArgs > $this->request->pass
• $this->params['named'] or $this->passedArgs > $this->request->named
• $this->request->params > $this->request->query へ
• $this->header > $this->request->header
• find($conditions) > find('all', $conditions)
• App::import(モデル) > ClassRegistry::init()
• $this->cakeError > Exception, ExceptionRender 利用
• $this->log() > CakeLog::config 利用
