Rails «link_to» дает неправильный путь для удаления вложенного ресурса

Question

Я сделал простое приложение блог в рельсах и когда я попытался дать ссылку, чтобы удалить комментарий по рельсам дал мне неверную ссылку

<a data-method="delete" href="/forums/27/comment.7" rel="nofollow">Delete</a> 

Это дало мне ошибка

No route matches [DELETE] "/forums/27/comment.7" 

, но когда я изменил его на

<a data-method="delete" href="/forums/27/**comments/7**" rel="nofollow">Delete</a> 

по Хрома Проверьте, что удален м y комментарий. Итак, как создать правильную ссылку?

Вы должны использовать forum_comment_path помощника:

= link_to "Delete", forum_comment_path(@forum, c), method: :delete
