Constante non initialisée OmniauthCallbacksController lors de la tentative d'inscription de l'utilisateur

Question

Je n'arrive pas à faire fonctionner OmniAuth. J'ai suivi ce tutoriel here pour essayer de l'implémenter avec mon application existante, mais j'arrive avec l'erreur ActionController::RoutingError at /users/auth/github/upgrade uninitialized constant OmniauthCallbacksController. J'ai regardé plusieurs autres postes de SO, mais la plupart de ces réponses traitent des fautes d'orthographe et j'ai vérifié trois fois que tout est orthographié correctement. Qu'est-ce qui pourrait interférer?

Modèle utilisateur:

class User < ActiveRecord::Base 
    devise :database_authenticatable, :registerable, 
       :recoverable, :rememberable, :trackable, :omniauthable 

    has_many :identities 

    def github 
     identities.where(:provider => "github").first 
    end 

    def github_client 
     @github_client ||= Github.client(access_token: github.accesstoken) 
    end 

    def linkedin 
     identities.where(:provider => "linkedin").first 
    end 

    def linkedin_client 
     @linkedin_client ||= Linkedin.client(access_token: linkedin.accesstoken) 
    end 
end 

Identité Modèle:

Modèle Devise:

Devise.setup do |config| 

    # config.omniauth :google_oauth2, ENV['GOOGLE_OAUTH2_APP_ID'], ENV['GOOGLE_OAUTH2_APP_SECRET'], scope: "email,profile,offline", prompt: "consent" 
    config.omniauth :github, ENV['GITHUB_APP_ID'], ENV['GITHUB_APP_SECRET'], setup: true 
    # config.omniauth :facebook, ENV['FACEBOOK_APP_ID'], ENV['FACEBOOK_APP_SECRET'], scope: "email" 
    config.omniauth :linkedin, ENV['LINKEDIN_APP_ID'], ENV['LINKEDIN_APP_SECRET'], setup: true 

Omniauth Modèle:

Rails.application.config.middleware.use OmniAuth::Builder do 

    provider :github, ENV['GITHUB_KEY'], ENV['GITHUB_SECRET'] 
    provider :linkedin, ENV['LINKEDIN_KEY'], ENV['LINKEDIN_SECRET'] 
end 

FormUser Modèle

class FormUser < User 
    attr_accessor :current_password 

    validates_presence_of :email, if: :email_required? 
    validates_uniqueness_of :email, allow_blank: true, if: :email_changed? 
    validates_format_of  :email, with: Devise.email_regexp, allow_blank: true, if: :email_changed? 

    validates_presence_of  :password, if: :password_required? 
    validates_confirmation_of :password, if: :password_required? 
    validates_length_of  :password, within: Devise.password_length, allow_blank: true 

    def password_required? 
    return false if email.blank? 
    !persisted? || !password.nil? || !password_confirmation.nil? 
    end 

    def email_required? 
    true 
    end 
end 

Omniauth Callbacks Controller:

    if @user.persisted? 
     @identity.update_attribute(:user_id, @user.id) 
     # This is because we've created the user manually, and Device expects a 
     # FormUser class (with the validations) 
     @user = FormUser.find @user.id 
     sign_in_and_redirect @user, event: :authentication 
     set_flash_message(:notice, :success, kind: provider.capitalize) if is_navigational_format? 
    else 
     session["devise.#{provider}_data"] = env["omniauth.auth"] 
     redirect_to new_user_registration_url

S'il vous plaît laissez-moi savoir s'il y a un autre code que vous pourriez avoir besoin de voir. Merci pour votre aide, cela me rend fou!

Answer 1

Vous avez des espaces de noms OmniauthCallbacksController sous les utilisateurs comme Users::OmniauthCallbacksController, assurez-vous que le chemin du contrôleur est your_app/app/controllers/users/omniauth_callbacks_controller‌​.rb dire, il se trouve sous le dossier users. De même, vos itinéraires devise devraient ressembler à:

devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" } 

Note:users/omniauth_callbacks

MISE À JOUR

En regardant les itinéraires que vous avez partagé, vous devez mettre à jour les routes pour upgrade et setup comme:

devise_scope :user do 
    get '/users/auth/:provider/upgrade' => 'users/omniauth_callbacks#upgrade', as: :user_omniauth_upgrade 
    get '/users/auth/:provider/setup', :to => 'users/omniauth_callbacks#setup' 
    end 

Encore une fois, Note:users/omniauth_callbacks
