フォロー機能(いいね機能と一緒)のcreate.js.erb ,destroy.js.erb のコードをコメントアウトしてもなぜか動く。

Question

いいね機能を参考にし中身は一緒でフォロー機能を作成したのですが、create.js.erb ,destroy.js.erb のコードに関わらず動作することに気づきコメントアウトしてみたところ、やはり一見フォロー機能は動作しているように見えます。
要するに非同期処理があたかも　remote true　だけで動いているということです。

(※立て続けの質問になるのですが、フォローボタンをおしたとき出現するフォロー解除ボタンが画像のように下に一段ずれてしまっています。)

ご指摘お願いします。

Answer 1

redirect_back(fallback_location: root_path)
しているので view までいってないのではないでしょうか。

create/destroyのログに Redirected to ... とありませんか？
