Rails не может генерировать миграцию для RailsGirlsBerlin App

Question

Редактировать: проблема была в маршрутизации, как я ее назвал.

Проблема кода маршрутизации была

get :to => redirect('attendees#index')

Код фиксирующее был

match "/attendees", to: 'attendee#index', via:'get'

Я иду через RailsGirls приложение учебник, и я добавил и в комплекте Геокодер и Gmaps4rails к Gemfile без каких-либо проблем , Я бегу это и получаю следующее сообщение об ошибке:

rails generate migration AddLatitudeAndLongitudeToAttendee latitude:float longitude:float 

Вот ошибка:

Во-первых, у меня есть мой контроллер очном и модели. Я видел подобный пост, но их проблема заключалась в отсутствии контроллера. Может кто-нибудь сказать мне, почему я получаю это сообщение об ошибке и в чем проблема? Я новичок в программировании и не знаю, как его читать.

Answer 1

Взгляните на файл routes.rb и посмотрите файл контроллера, на который ссылается ошибка - проверьте наличие орфографических ошибок. Вот аналогичное сообщение об ошибке, и решение было всего лишь ошибкой в ​​синтаксисе - сравните что у вас есть в учебнике, и если вы не можете найти ошибку - опубликуйте файлы здесь и получите второй набор глаз на них!
