Ruby on Rails - Omniauth Facebook или Twitter - AuthServicesController

Question

Я новичок в Ruby on Rails, и я хочу создать систему omniauth-devise с facebook и twitter как способ входа в мое приложение. Прямо сейчас я в значительной степени в точке (я думаю) о том, чтобы ее запустить. Тем не менее, я получаю следующее сообщение об ошибке:

Маршрутизации Ошибка

неинициализированной постоянной AuthServicesController

Попробуйте запустить реки маршруты для получения дополнительной информации о доступных маршрутах.

И я не могу продолжать работу с логгином.

Я проводил много исследований в сети, но я не могу найти никого с той же или подобной проблемой.

Кто-нибудь знает, что это такое? Я сразу потерялся.

Большое спасибо!

Кстати, весь код, я получил в Services_controller.rb является следующее:

Ваш класс объявлен как:

class ServicesController < ApplicationController 

И вы получаете эту ошибку:

uninitialized constant AuthServicesController 

Обратите внимание на разницу между ServiceController и AuthServicesController, и я считаю, что вы нашли решение своей проблемы. Другими словами, я считаю, что вы должны объявить свой класс следующим:

class AuthServicesController < ApplicationController
