Ошибка маршрутизации Rails: action =› 'new' возвращает ошибку «Нет совпадений маршрута {:action=›» show» в контроллере

Модель «Проект» была сгенерирована с помощью строительных лесов.

config/routes.rb содержит линейные ресурсы :projects.

У меня есть ссылка из представления index на new_project_path.

Проблема со ссылкой на /new. URL-адрес приложения/проекта/нового имеет следующую ошибку:

Маршрут не соответствует {:action=>"show", :controller=>"projects"}

Раньше работало, а теперь не работает, не знаю почему. Любые идеи?
