1 はじめに

• Railsのチュートリアルをやっていたらルーティング情報取得のところで

  kiri@smtp:~/projects/rails/sample_view[1847]% rake routes
  rake aborted!
  Don't know how to build task 'routes' (See the list of available tasks with `rake --tasks`)
  
  (See full trace by running task with --trace)
  kiri@smtp:~/projects/rails/sample_view[1848]% 

  と叱られる

• これは4.0以降の変更
  • `rake routes'⇒`rails routes'

  • しかしこれでは不用なルーティング情報が大量に出て見難い

    　こんなかんじ

  • ユーザーが作ったコントローラやモデルのみを出力するには？⇒https://github.com/ctran/annotate_models/issues/845
  • 3つの方法があることが判明
    1. スクリプトによる方法
    2. モデル抽出による方法
    3. annotateによる方法

    • 1.と2.はスクリプトを書いて

      task routes: :environment do
        ここに入れる
      end

      としてlib/tasks/routes.rakeに置き，`rake routes'で出力

    • 3.はrubygem-annotateをインストールしannotateコマンドで行なう
