普通のRoute

ActionController::Routing::Routes.draw do |map|
  map.resources :tasks
end

% rake routes
    tasks GET    /tasks(.:format)          {:action=>"index", :controller=>"tasks"}
          POST   /tasks(.:format)          {:action=>"create", :controller=>"tasks"}
 new_task GET    /tasks/new(.:format)      {:action=>"new", :controller=>"tasks"}
edit_task GET    /tasks/:id/edit(.:format) {:action=>"edit", :controller=>"tasks"}
     task GET    /tasks/:id(.:format)      {:action=>"show", :controller=>"tasks"}
          PUT    /tasks/:id(.:format)      {:action=>"update", :controller=>"tasks"}
          DELETE /tasks/:id(.:format)      {:action=>"destroy", :controller=>"tasks"}

APIの場合、newとeditのページは要らないので絞る。

ActionController::Routing::Routes.draw do |map|
  map.resources :tasks, :except => [:new, :edit]
end

% rake routes
tasks GET    /tasks(.:format)     {:action=>"index", :controller=>"tasks"}
      POST   /tasks(.:format)     {:action=>"create", :controller=>"tasks"}
 task GET    /tasks/:id(.:format) {:action=>"show", :controller=>"tasks"}
      PUT    /tasks/:id(.:format) {:action=>"update", :controller=>"tasks"}
      DELETE /tasks/:id(.:format) {:action=>"destroy", :controller=>"tasks"}

NESTしたRouteでも絞ろうとすると、

ActionController::Routing::Routes.draw do |map|
  map.resources :project, :has_many => :tasks, :except => [:new, :edit]
end

% rake routes
    project_tasks GET    /project/:project_id/tasks(.:format)          {:action=>"index", :controller=>"tasks"}
                  POST   /project/:project_id/tasks(.:format)          {:action=>"create", :controller=>"tasks"}
 new_project_task GET    /project/:project_id/tasks/new(.:format)      {:action=>"new", :controller=>"tasks"}
edit_project_task GET    /project/:project_id/tasks/:id/edit(.:format) {:action=>"edit", :controller=>"tasks"}
     project_task GET    /project/:project_id/tasks/:id(.:format)      {:action=>"show", :controller=>"tasks"}
                  PUT    /project/:project_id/tasks/:id(.:format)      {:action=>"update", :controller=>"tasks"}
                  DELETE /project/:project_id/tasks/:id(.:format)      {:action=>"destroy", :controller=>"tasks"}
    project_index GET    /project(.:format)                            {:action=>"index", :controller=>"project"}
                  POST   /project(.:format)                            {:action=>"create", :controller=>"project"}
          project GET    /project/:id(.:format)                        {:action=>"show", :controller=>"project"}
                  PUT    /project/:id(.:format)                        {:action=>"update", :controller=>"project"}
                  DELETE /project/:id(.:format)                        {:action=>"destroy", :controller=>"project"}

projectの方しか絞れない。

こっちの書き方なら両方絞れる。

ActionController::Routing::Routes.draw do |map|
  map.resources :projects, :except => [:new, :edit] do |project|
    project.resources :tasks, :except => [:new, :edit]
  end
end

% rake routes
project_tasks GET    /projects/:project_id/tasks(.:format)     {:action=>"index", :controller=>"tasks"}
              POST   /projects/:project_id/tasks(.:format)     {:action=>"create", :controller=>"tasks"}
 project_task GET    /projects/:project_id/tasks/:id(.:format) {:action=>"show", :controller=>"tasks"}
              PUT    /projects/:project_id/tasks/:id(.:format) {:action=>"update", :controller=>"tasks"}
              DELETE /projects/:project_id/tasks/:id(.:format) {:action=>"destroy", :controller=>"tasks"}
     projects GET    /projects(.:format)                       {:action=>"index", :controller=>"projects"}
              POST   /projects(.:format)                       {:action=>"create", :controller=>"projects"}
      project GET    /projects/:id(.:format)                   {:action=>"show", :controller=>"projects"}
              PUT    /projects/:id(.:format)                   {:action=>"update", :controller=>"projects"}
              DELETE /projects/:id(.:format)                   {:action=>"destroy", :controller=>"projects"}

スッキリ！
