राउटिंग त्रुटि अनियमित स्थिर उपयोगकर्ता

Question

मैं रेल की नौसिखिया हूं ... मैं एक डेमो ऐप के लिए फेसबुक के साथ साइन इन करने की कोशिश कर रहा हूं। मैं OmniAuth उपयोग कर रहा हूँ और इस ट्यूटोरियल

https://github.com/plataformatec/devise/wiki/OmniAuth:-Overview

मैं जब अमेरिकन प्लान के लिए पुनः निर्देशित इस त्रुटि मिलती है निम्नलिखित:

Routing Error: 

    uninitialized constant Users 

    Try running rake routes for more information on available routes. 

पर्यावरण

Windows 7 
Rails version :3.2.9.rc2 
omniauth-1.1.1 
devise-2.1.2 

मेरे routes.rb इस तरह दिखता है :

root :to => 'static_pages#home' 
    resources :users 
    get "static_pages/home" 
    match '/auth/facebook' => 'omniauth#passthru' 
    match '/users/auth/facebook' => 'users/omniauth_callbacks#passthru' 
    devise_for :users, :controllers => { :omniauth_callbacks => "users/omniauth_callbacks" } , :strategy_class => OmniAuth::Strategies::Facebook 

devise.rb शामिल हैं:

require 'devise/orm/active_record' 
require 'omniauth-facebook' 

config.omniauth_path_prefix = "https://stackoverflow.com/users/auth" 
    config.omniauth :facebook, "ABC", "XYZ",{:client_options => { :ssl => { :verify => false } }} 

और OmniAuthController शामिल हैं: यानी एप्लिकेशन/नियंत्रक/omniauth_callbacks_controller.rb

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController 

    def facebook 
    # You need to implement the method below in your model (e.g. app/models/user.rb) 
    @user = User.find_for_facebook_oauth(request.env["omniauth.auth"], current_user) 

    if @user.persisted? 
     sign_in_and_redirect @user, :event => :authentication #this will throw if @user is not activated 
     set_flash_message(:notice, :success, :kind => "Facebook") if is_navigational_format? 
    else 
     session["devise.facebook_data"] = request.env["omniauth.auth"] 
     #redirect_to new_user_registration_url 
     redirect_to "static_pages_home" 
    end 
    end 

    def passthru 
    render :file => "#{Rails.root}/public/404.html", :status => 404, :layout => false 
    # Or alternatively, 
    # raise ActionController::RoutingError.new('Not Found') 
    end 


end 

मॉडल User.rb शामिल हैं:

class User < ActiveRecord::Base 
    # Include default devise modules. Others available are: 
    # :token_authenticatable, :confirmable, 
    # :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 

    # Setup accessible (or protected) attributes for your model 
    attr_accessible :email, :password, :password_confirmation, :remember_me 
    attr_accessible :date_of_birth, :firstName, :lastName, :mailId, :phone, :provider, :uid 
    devise :omniauthable 

protected 


def self.find_for_facebook_oauth(auth, signed_in_resource=nil) 
    user = User.find(:provider => auth.provider, :uid => auth.uid).first 
    unless user 
     user = User.create(name:auth.extra.raw_info.name, 
          provider:auth.provider, 
          uid:auth.uid, 
          email:auth.info.email, 
          password:Devise.friendly_token[0,20] 
          ) 
    end 
    user 
    end 

def self.new_with_session(params, session) 
    super.tap do |user| 
     if data = session["devise.facebook_data"] && session["devise.facebook_data"]["extra"]["raw_info"] 
     user.email = data["email"] if user.email.blank? 
     end 
    end 
    end 

end

Answer 1

mv

एप्लिकेशन/नियंत्रक/omniauth_callbacks_controller.rb

एप्लिकेशन/नियंत्रक/उपयोगकर्ताओं/omniauth_callbacks_controller करने के लिए।आरबी

या

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController 

बदलने

class OmniauthCallbacksController < Devise::OmniauthCallbacksController 

Answer 2

मुझे विश्वास है कि हिस्सा खिलवाड़ कर रहा है:

match '/users/auth/facebook' => 'users/omniauth_callbacks#passthru' 

लिटिल परीक्षण, आप के लिए:

में डाल आपका विचार:

<%= link_to users_auth_facebook_path, users_auth_facebook_path %> 

और क्लिक के साथ इसे का पालन, यह भी बहुत ही त्रुटि देता है ...

मेरा मानना ​​है कि आप की तरह कुछ (क्या विकि आप ऊपर लिंक में बताया गया है) का उपयोग करना चाहिए:

devise_scope :user do 
    get '/users/auth/:provider' => 'users/omniauth_callbacks#passthru' 
end 

और करने के लिए विधि passthru लपेट कार्रवाई को सौंपने निजी/संरक्षित पैरामीटर के आधार पर विधि उपयुक्त [: प्रदाता] मूल्य

class Users::OmniauthCallbacksController < Devise::OmniauthCallbacksController 
    def passthru 
    send(params[:provider]) if providers.include?(params[:provider]) 
    end 

    protected 

    def facebook 
    raise "Implement me for facebook" 
    end 

    def twitter 
    raise "Implement me for twitter" 
    end 

    private 

    def providers 
    ["facebook", "twitter"] 
    end 
end
