CakePHP でモデルを使わないコントローラーにて Notice が大量発生する

時刻: Labels: ,
どべーっと。
大量に出ることがあります。
ちょっとした間違いが原因でした。

CakePHP は 1.3.10

Fatal error: require() [http://php.net/function.require]: Cannot redeclare class object in /hogehoge/cake/bootstrap.php on line 33

原因としては コントローラの $uses の値。
モデルを使わないので $uses を false にしてた。
class SomeController extends AppController {
    var $name = 'Some';
    var $uses = false; // ここ

    function index()
    {

    }
}

これが間違い。
正解はこっち。
class SomeController extends AppController {
    var $name = 'Some';
    var $uses = array(); // ここ

    function index()
    {

    }
}

コントローラでモデルを使いたくないのならば、var $uses = array()としてください。これでコントローラに一致するモデルファイルを必要としないコントローラを使うことができるようになります。

まあなんでこうしちゃったかって言うと、
モデルでテーブルを使いたくない時は
class Example extends AppModel {
    var $useTable = false; // このモデルはデータベーステーブルを使用しない
}
とモデルの場合は false なんですよね。

ごっちゃになって覚えてたみたいです。
