Public key

Have the ability to have a public key, which is used by the resources with the underlying model using a different primary key. For example internally the models use integer primary keys and externally the resources use uuids.

Initially this project was trying to make the primary_key option perform both roles, which was problematic. I think it might be possible however to make this feature work with a public_key option on a Resource.

This has been requested several times, and recently #427 brought this up again.

まず、Resource が現在どのように主キーを扱っているか、および issue #427 の関連する議論を確認します。モデル内部の主キーと Resource の公開キーの意図された分離を定義し、UUID をどのように公開して解決するかも含めます。この機能は、その動作が仕様化され、要求されたユースケースについてカバーされた時点で完了です。
