je veux me connecter à mon site web en utilisant compte facebook, j'ai d'abord créé le fichier facebook.yml dans la configurationauthentification Facebook on Rails 5, aucune méthode [] Erreur
development:
app_id: 28679*********
secret: ba02f0735cfdd4************
Puis j'ai créé facebook.rb dans/config/initializers
FACEBOOK_CONFIG = YAML.load_file("#{::Rails.root}/config/facebook.yml")[::Rails.env]
Ensuite, je fais un autre fichier appelé omniauth.rb
OmniAuth.config.logger = Rails.logger
Rails.application.config.middleware.use OmniAuth::Builder do
provider :facebook, FACEBOOK_CONFIG['app_id'], FACEBOOK_CONFIG['secret'], {:scope => 'public_profile, email'},{:info_fields => 'id,first_name,middle_name,last_name,email,name,link'}
end
Maintenant, si je lance tout ce qu'il continue à dire que
rake aborted!
