【Rails】resourcesとresourceの違い

Posted at

表記ミスかと思ったらちゃんとresourceも存在した。

##resources

routes.rb
...
resources :posts
...
Prefix Verb              URI Pattern               Controller#Action
posts_path      GET  	/posts(.:format)	       posts#index
                POST	/posts(.:format)	       posts#create
new_post_path	GET  	/posts/new(.:format)	   posts#new
edit_post_path	GET	    /posts/:id/edit(.:format)  posts#edit
post_path	    GET	    /posts/:id(.:format)       posts#show
                PATCH	/posts/:id(.:format)	   posts#update
                PUT	    /posts/:id(.:format)	   posts#update
                DELETE	/posts/:id(.:format)	   posts#destroy

##resource

indexとid付きのパスが生成されない。

たとえば、/profileでは常に「現在ログインしているユーザー自身」のプロファイルを表示し、他のユーザーidを参照する必要がないとする。

単数形で定義するのに注意!

routes.rb
...
resource :post
...
Prefix Verb              URI Pattern               Controller#Action
new_post_path	GET  	/post/new(.:format)	      posts#new
edit_post_path	GET	    /post/edit(.:format)      posts#edit
post_path	    GET	    /post(.:format)           posts#show
                PATCH	/post(.:format)	          posts#update
                PUT	    /post(.:format)	          posts#update
                DELETE	/post(.:format)	          posts#destroy
                POST	/post(.:format)	          posts#create

どちらも同じコントローラーで同時に定義できる。
