link_toでフォロワー一覧ページに遷移したいのですが、困っています...

Question

前提・実現したいこと

いつもお世話になっております。今回もよろしくお願いします
app/views/users/show.html.haml上段のlink_toからapp/views/users/follow.html.haml(フォロー中ユーザー・フォロワーを表示するページ)に遷移したいです。
= link_to(@user.followings.count,followings_user_path(@user.id))のように書いたのですが、'/users/1/followers'のようなstringのキーは存在しませんと怒られます。
この場合は、、'/users/1/followers'が文字列として認識されているということなんでしょうか？お知恵をお貸しいただけると幸いです。

Answer 1

フォロワーのほうの第二引数root_pathが要らないのでは

  フォロワー：
= link_to(@user.followers.count,root_path,followers_user_path(@user.id))
