Hoge::Application.routes.draw do  resources :usersend

@kenn

Is it only me who think rails routes.rb is a mess?

routes.rb 開くたびに憂鬱になる

routes.rb sucks?

routes.rb の悪いところを考えてみた

I.resources が直感的でない

基本7アクションindex

show

new

edit

create

update

destroy

$ rake routes users GET /users(.:format) users#index POST /users(.:format) users#create new_user GET /users/new(.:format) users#newedit_user GET /users/:id/edit(.:format) users#edit user GET /users/:id(.:format) users#show PUT /users/:id(.:format) users#update DELETE /users/:id(.:format) users#destroy

resources :users

GET POST PUT DELETE

/users index create - -

/users/:id show - update destroy

GET /users/new → newGET /users/:id/edit → edit

resources :users

II.Convention over

Configuration じゃない

7アクションが「規約」なら resources も書かなくてもいい

のでは？

Conventional Routes

https://github.com/tkawa/conventional_routes

http://d.hatena.ne.jp/tkawa/20120407/p1

namespace :admin do   namespace :special do     resources :licenses   end   resources :users end resources :users

app/controllers/admin/special/licenses_controller.rbapp/controllers/admin/users_controller.rbapp/controllers/users_controller.rb

Conventional Routes

Conventional Routes

• routes.rb に何も書かなくても、コントローラが存在すれば、自動的に

resources とみなす

• ディレクトリは namespace

• もしコントローラの中まで見れば、Sinatra的なこともできそう

Sinatra的なことをもうやってる人がいた！（しかも2年前）

Routes are unnecessary configuration.

The seven standard controller actions are legacy.

Become intimate with your URLs – don’t abstract them away.

Decrease the distance between thought and implementation.

Let the controller do its job.

http://peepcode.com/blog/2010/rethinking-rails-3-routes

# Class method and HTTP-style methods.class ReportsController < ApplicationController  before_filter :authenticate  resource "/reports(/:id)"

  get(:collection) do  end

  get(:member) do |id|  end

  put(:member) do |id|  end

end

His idea

Astaire

https://github.com/pehrlich/astaire

# Class method and HTTP-style methods.class ReportsController < ApplicationController  before_filter :authenticate

  get "/reports" do  end

  get "/reports/:id" do  end

  put "/reports/:id" do  end

end

Astaire (like Sinatra)

2年も経ってるのに反応薄いし、やっぱりいまいち？

• Viewの命名規約が別途必要{view}.html.erb どういう名前にする？

• resources のパターンを活かせない

GET POST PUT DELETE

/reports index create - -

/reports/:id show - update destroy

Sinatra式の問題点

いろいろ考えたけど• 今の routes.rb はそれなりにベター

• 基本7アクションを残すなら、match (get, post, put, delete) はむしろ書かなくてすむようにしたい

• とにかく resources (resource) にすることで、

routes.rb はシンプルになる。REST的にもOK

resources :messages, except: [ :new ] do post :trash, :restore, on: :member resources :image_attachments, only: :index end

https://github.com/rails/routing_concerns

例

resources :messages, except: [ :new ] do post :trash, :restore, on: :member resources :image_attachments, only: :index end

resources :messages, except: [ :new ] do member do put :trashed delete :trashed end resources :image_attachments, only: :index end

resources :messages, except: [ :new ] do member do put :trashed delete :trashed end resources :image_attachments, only: :index end

resources :messages, except: [ :new ] do resource :trashed, only: [:create, :destroy] resources :image_attachments, only: :index end

# “partial” option does not exist in fact resources :messages, except: [ :new ], partial: [:trashed] do resources :image_attachments, only: :index end
