parameters:
hoge: fuga
あとはこう。
$this->container->getParameter('hoge');
【Symfony2.3】parameters.ymlに登録したパラメーターをコンテナから取得する。
【Symfony2.3】ファイルの操作を行う。
Symfony\Component\Filesystem\Filesystemを用いる。
use Symfony\Component\Filesystem\Filesystem;
use Symfony\Component\Filesystem\Exception\IOException;
$fs = new Filesystem();
try {
$fs->mkdir('/tmp/random/dir/' . mt_rand());
} catch (IOException $e) {
echo "An error occurred while creating your directory";
}
これは便利。
メソッド一覧など詳細は下記URLを参照。

【AngularJS】フィルタリング済みの件数を取得する。
検索機能などの実装時、フィルタリング後の件数を取得したい場合。
<span>{{(data|filter:query).length}}</span>
queryで絞った後の配列のlengthを参照してやればOK。
下記のような方法もエレガント。
<div ng-repeat="person in filtered = (data | filter: query)"> </div>
で、こうする。
Showing {{filtered.length}} Persons
リピートの母体にそもそもフィルタリング後のデータを注入してやるのは斬新。
【AngularJS】コントローラーからフィルターを使う方法。
まずはコントローラーに「$filter」サービスを注入する。
function myCtrl($scope, $filter)
{
}
次に使いたいフィルターを呼び出す
$filter('filtername');
引数を渡してやれば完成。
function myCtrl($scope, $filter)
{
$filter('filtername')(arg1,arg2);
}
arg1にng-repeatでも用いるリストを渡せばOK。
【Symfony2】エクセプションまとめ。
2.1時代のものだけど参考にはなりそう。
