Tengo una aplicación de rieles que utiliza omniauth para autenticar a los visitantes a través de Facebook.

Cuando registra una aplicación con Facebook, debe registrar una URL de devolución de llamada a la que redirigirán una vez que hayan completado su proceso de autenticación.

Dado que mi sitio de producción está alojado en un servidor diferente al de mi entorno de desarrollo, necesito registrar 2 URL diferentes en Facebook. Lo hice registrando dos aplicaciones, una en vivo y una versión para desarrolladores.

Ahora, por supuesto, tengo dos app_ids y dos app_secrets que mi aplicación Rails necesita usar.

¿Cómo configuro OmniAuth para usar un conjunto de claves en el entorno de desarrollo y otro en producción?

Intenté configurar mis claves en mi directorio / config / entornos de la siguiente manera:

# development.rb
SampleApp::Application.configure do
  config.omniauth_keys.facebook.app_id = "32423423"
  config.omniauth_keys.facebook.api_key = "324234324234324"
  config.omniauth_keys.facebook.app_secret = "242343424234324324234324"
end

# production.rb
SampleApp::Application.configure do
  config.omniauth_keys.facebook.app_id = "7657566"
  config.omniauth_keys.facebook.api_key = "7756765765756757"
  config.omniauth_keys.facebook.app_secret = "65756767567567567757"
end

y luego en /config/initializers/omniauth.r

Rails.application.config.middleware.use OmniAuth::Builder do 
  keys = SampleApp::Application.config.omniauth_keys

  # ==> OmniAuth Provider Credentials
  #                   APP_ID                SECRET_ID
  provider :facebook, keys.facebook.app_id, keys.facebook.app_secret
end

pero obtengo

`method_missing': undefined method `omniauth_keys'

cuando trato de iniciar el servidor de desarrollo, supongo que omniauth.rb se carga antes / emvironments / *?

¿Cómo puedo configurar esto?
