prevents the use of attributes that match core functions

I'm creating a resource that has a method attribute, but due to the way it works now:

  define_method attr do
    @model.public_send(options[:delegate] ? options[:delegate].to_sym : attr)
  end unless method_defined?(attr)

It fails to work for me. I know method is a core ruby function, but it's also the word used to describe HTTP's GET and PUT.

One option is to simply drop the unless. Allow rewriting, but warn.

Another option is to provide an in and out type option. Currently I would describe delegate as the in, where it describes how to take in the data, and I would provide a key option as the out functionality (what the resulting key will look like).

issue に示されている resource 属性の定義から始め、method_defined? が method などの名前に対する生成アクセサーをどのようにブロックしていたかを調べます。衝突を警告付きで上書きするべきか、明示的な出力キーにマッピングするべきかを決定し、選択した挙動のリグレッションカバレッジを追加します。
