我有一个东西博客应用程序，我想缩短我的路线。这里有：
Blog::Application.routes.draw do
resources :categories do
resources :articles do
resources :comments
end
end
rake routes命令构建以下行：
GET /categories/:category_id/articles/:article_id/comments(.:format) {:controller=>"comments", :action=>"index"}
category_article_comments POST /categories/:category_id/articles/:article_id/comments(.:format) {:controller=>"comments", :action=>"create"}
new_category_article_comment GET /categories/:category_id/articles/:article_id/comments/new(.:format) {:controller=>"comments", :action=>"new"}
GET /categories/:category_id/articles/:article_id/comments/:id(.:format) {:controller=>"comments", :action=>"show"}
PUT /categories/:category_id/articles/:article_id/comments/:id(.:format) {:controller=>"comments", :action=>"update"}
category_article_comment DELETE /categories/:category_id/articles/:article_id/comments/:id(.:format) {:controller=>"comments", :action=>"destroy"}
edit_category_article_comment GET /categories/:category_id/articles/:article_id/comments/:id/edit(.:format) {:controller=>"comments", :action=>"edit"}
GET /categories/:category_id/articles(.:format) {:controller=>"articles", :action=>"index"}
category_articles POST /categories/:category_id/articles(.:format) {:controller=>"articles", :action=>"create"}
new_category_article GET /categories/:category_id/articles/new(.:format) {:controller=>"articles", :action=>"new"}
GET /categories/:category_id/articles/:id(.:format) {:controller=>"articles", :action=>"show"}
PUT /categories/:category_id/articles/:id(.:format) {:controller=>"articles", :action=>"update"}
category_article DELETE /categories/:category_id/articles/:id(.:format) {:controller=>"articles", :action=>"destroy"}
edit_category_article GET /categories/:category_id/articles/:id/edit(.:format) {:controller=>"articles", :action=>"edit"}
GET /categories(.:format) {:controller=>"categories", :action=>"index"}
categories POST /categories(.:format) {:controller=>"categories", :action=>"create"}
new_category GET /categories/new(.:format) {:controller=>"categories", :action=>"new"}
GET /categories/:id(.:format) {:controller=>"categories", :action=>"show"}
PUT /categories/:id(.:format) {:controller=>"categories", :action=>"update"}
category DELETE /categories/:id(.:format) {:controller=>"categories", :action=>"destroy"}
edit_category GET /categories/:id/edit(.:format) {:controller=>"categories", :action=>"edit"}
可以看出，每个资源都在树中排序。所以我相信，简化我的路线可能会很有趣，例如：
/categories/ => /
/categories/:id => /:id
/categories/:category_id/articles/ => /:category_id/articles
/categories/:category_id/articles/:id => /:category_id/:id
/categories/:category_id/articles/:article_id/comments/ => /:category_id/:article_id/comments
/categories/:category_id/articles/:article_id/comments/:id => /:category_id/:article_id/:id
它更干燥，不是吗？:)
Rails 3 是否提供了一种简单的方法来做到这一点，将 HTTP 动词自动映射到控制器操作？谢谢任何人。
