Нет совпадений в маршруте [POST] "/ collections/1/photos/new"

Question

Может кто-нибудь помочь мне с этой ошибкой?

Я только что начал основной проект Rails, где у меня есть Коллекции. Каждая коллекция может иметь несколько Фотографии.

Однако, я могу создать эти Коллекции. Но whenenver я хочу создать фото, прикрепленные к коллекции я получаю эту ошибку:

No route matches [POST] "/collections/1/photos/new"

Answer 1

Ваша форма оказывает неправильный URL

new_collection_photo_path

Это должно быть

collection_photos_path
