ルーティングについての備忘

以下は同じ
memo_path(memo)
"/memos/#{memo.id}"

rake routeで実行することでPrefixを確認できる

route
Prefix Verb   URI Pattern          Controller#Action
  root GET    /                    memos#index
 memos POST   /memos(.:format)     memos#create
  memo DELETE /memos/:id(.:format) memos#destroy

例えば、memos#destroyに対応するパスに「memo」というPrefixが付与されていることがわかります。
link_toの第二引数を(Prefix名)_pathとすると、そのPrefixに対応するパスをリンク先として指定することができます。

destroyのように、パラメータとしてidが必要になる場合、(Prefix名)_pathの後に括弧をつけて、そのインスタンスを渡します。
