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

エラーメッセージをよく読みましょう。

app/views/users/show.html.haml:9

9行目です。

ActionView::Template::Error (undefined method `stringify_keys' for "/users/1/followers":String):
     6: = link_to(@user.followings.count,followings_user_path(@user.id))
     7: %p
     8:   フォロワー：
     9: = link_to(@user.followers.count,root_path,followers_user_path(@user.id))
    10: = render('relationships/follow_form',user: @user) 
    11: [e-mail] do |tour|
    12:   .card.my-1

質問に書いた行は6行目ですね。9行目の引数の数を確認してみてください。

matherさん回答ありがとうございます...
おっしゃる通り９行目のroot_pathが要りませんでした。。
エラーをきちんと読まないまま質問をしてしまいました。本当にすみません！
助かりました！！！

Answer 2

※削除した質問となにか変わってます？

フォロワーのほうのlink_to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))

hellomarthaさん回答ありがとうございます...
おっしゃる通り第二引数を除いたところ問題なく実装できました。
教えていただき感謝の限りです！
エラーにもちゃんと書いてあったのになぜ気が付かなかったのか自分でも不思議です・・・
回答ありがとうございました！！
