今回は、Railsアプリケーションに、Undo/Redo機能を追加する プラグインの紹介です。

What is RUR (Rails Undo Redo)

RUR (Rails-Undo-Redo) is a rails plugin (and soon a gem as well) to make it so easy to implement multi-level undo redo in your Rails application that you better start thinking of better excuses not to implement Undo/Redo (no, seriously, it is going to be a lot easier).

これはなかなか面白いプラグインですね。後で使ってみよう。
