NameError at/uninitialized constant SearchReservationController :: Search

Question

Я пытаюсь сделать запросы к SOAP XML webservice/api, создав простой индексный указатель и контроллер. Пользователь вводит две простые части информации: номер подтверждения и адрес электронной почты, и он получает ответ от веб-службы, предоставляя ему информацию о его бронировании.

Это все работает в одном рубиновом файле, выводя правильную информацию на консоль. Но мне сложно интегрировать его в проект Rails 4. Я застрял с этой ошибкой:

Я положил свой оригинальный рубиновый файл search_reservation.rb в Lib папки Rails', обернутый класс в модуле (Search), а затем изменил application.rb включить эту строку: config.autoload_paths << Rails.root.join('lib')

Вот мой полный след ошибка из терминала:

Answer 1

Try по changeing в SearchReservationController#index на линии

search_reservation = Search::SearchReservation.new 

с

search_reservation = SearchReservation.new 

Или, попробуйте обернуть класс SearchReservation в модуле поиска.

class Search::SearchReservation 

И да ... это изменить в /application.rb и перезапустить приложение,

config.autoload_paths << Rails.root.join('lib').to_s 

Answer 2

Проблема здесь состоит в том, что рельсы пытается получить доступ к Search модуль в пространстве имен контроллера.

Попробуйте принуждая «основной» пространство имен, используя :: как этот

search_reservation = ::Search::SearchReservation.new 

Я также не уверен, что ваш автозагрузку, попробуйте изменить свой формат

config.autoload_paths += %W(#{Rails.root}/lib)
