Почему я не могу уничтожить эту запись Rails?

0 голосов
/ 21 января 2020

Я не могу удалить эту запись о бронировании рельсов из индекса. html .erb страница за всю мою жизнь. Я попробовал несколько вещей, которые я прочитал на этом форуме. Чего мне не хватает в действии уничтожения или в другом месте?

Я получаю этот ответ, когда нажимаю кнопку удаления: ActiveRecord :: RecordNotFound в ReservationsController # show Не удалось найти резервирование с 'id' = 32 (неважно какую запись я удаляю я получаю тот же ответ)

ruby 2.6.3 рельсы 6.0.2

По вашему журналу резервирование успешно удалено, но вы пытаетесь просмотреть его после удаления. В вашем destroy методе смените 

redirect_to reservation_url

на 

redirect_to reservations_url

При destroy изменении метода URL как упомянутое «@Vitauts Stočka» или пользовательское как root_url.

Журнал:

Запрос на удаление id=32 с последующим перенаправлением на поиск бронирование с id=32

Из журнала видно, что бронь действительно удалена. Проблема в том, что вы перенаправлены на просмотр удаленного бронирования, который больше не существует. Поэтому вы получаете ошибку 404.

В методе уничтожения попробуйте перенаправить на reservations_url (путь индекса) вместо reservation_url.
