.dotファイルを作成するrailsのモデリングツール。
.dotファイルはGraphvizってツールで見たり、画像に書き出したりできる。
インストール
gem install railroad
Graphvizからdmgをダウンロード
使い方
railsのルートディレクトリで以下を実行。
railroad -o doc/models.dot -M
railroad -o doc/controllers.dot -C
Graphvizで.dotファイルをopen
controllerでエラー
$ railroad -o doc/controllers.dot -C Error loading controller classes. (Are you running railroad on the aplication's root directory?) /opt/local/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require': no such file to load -- app/controllers/application.rb (MissingSourceFile) from /opt/local/lib/ruby/vendor_ruby/1.8/rubygems/custom_require.rb:31:in `require' from /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/dependencies.rb:156:in `require' from /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/dependencies.rb:521:in `new_constants_in' from /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.2/lib/active_support/dependencies.rb:156:in `require' from /opt/local/lib/ruby/gems/1.8/gems/railroad-0.5.0/lib/railroad/controllers_diagram.rb:39:in `load_classes' from /opt/local/lib/ruby/gems/1.8/gems/railroad-0.5.0/lib/railroad/app_diagram.rb:21:in `initialize' from /opt/local/lib/ruby/gems/1.8/gems/railroad-0.5.0/lib/railroad/controllers_diagram.rb:14:in `initialize' from /opt/local/lib/ruby/gems/1.8/gems/railroad-0.5.0/bin/railroad:38:in `new' from /opt/local/lib/ruby/gems/1.8/gems/railroad-0.5.0/bin/railroad:38 from /opt/local/bin/railroad:19:in `load' from /opt/local/bin/railroad:19
エラーメッセージから「app/controllers/application.rb」が原因のよう。
rails2.3以降、「application.rb」が「application_controller.rb」になったとこだろうと推測。
/opt/local/lib/ruby/gems/1.8/gems/railroad-0.5.0/lib/railroad/controllers_diagram.rb:39
を見てみると案の定requireしていたのでコメント
#require "app/controllers/application.rb"
解決。
こんな感じ
モデルは使えそう。
