Я думаю, что это все, что будет необходимо, чтобы помочь. Я уже некоторое время борется. Это мой первый пост, извините, если читать его непросто.

Answer 1

correct_user? нигде не определен. синтаксический сахар

redirect_to(root_url) unless correct_user?(@user)

Rails является собирается искать флаг correct_user модели или булевой возвращающих функции #correct_user? добытчик. Я предполагаю, что вы пытаетесь проверить, что запрос на обновление от пользователя действительно принадлежит правильному пользователю. Для этого вы должны иметь current_user, хранящийся в сеансе, а затем проверить параметр запроса [: id] == current_user.id
