次のロックされたスキーマを含む Reads という名前のモデルがあるとします。
protected $_schema = array(
'_id' => array('type' => 'id'),
'name' => array('type' => 'string', 'unique' => true),
'read_by' => array('type' => 'string', 'array' => true)
);
「read_by」フィールドには、実際には特定の記事を読んだユーザーのリストが含まれています。モデルがロードされるか ::find() が呼び出されると、現在ログインしているユーザーの ID が read_by にある場合は true を返し、そうでない場合は false を返す「read」という別のフィールドが必要です。これは可能ですか？::applyFilter メソッドの使用を検討しましたが、そこからどこに行くべきかわかりません。
Mongo をデータベースとして使用しています。ありがとう。
以下のデイブの回答によると、 $chain->next($self, $params, $chain); によって設定された $result オブジェクトを編集します。フィルターでは、次のように表示されます。
