私はレール初心者です...デモアプリ用にFacebookでサインインを設定しようとしています。私はOmniAuthを使用しており、このチュートリアルに従っています

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

fBにリダイレクトすると、次のエラーが発生します。

   Routing Error:

    uninitialized constant Users

    Try running rake routes for more information on available routes.

環境

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

私のroutes.rbは次のようになります：

  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に含まれるもの：

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

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

また、OmniAuthControllerには次のものが含まれます。つまり、app / controllers / 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

モデルUser.rbには次のものが含まれています。

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

痕跡：

2012-11-23 22:39:32 -0800（facebook）で127.0.0.1のGET "/ users / auth/facebook"を開始しました。コールバックフェーズが開始されました。

GET "/ users / auth / facebook / callback？を開始しました

state=XYZ&code=ABC" for 127.0.0.1 at 2012-11-23 22:39:33 -0800

その部分が台無しになっていると思います：

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

あなたのためのちょっとしたテスト：

あなたの見解に入れてください：

<%= link_to users_auth_facebook_path, users_auth_facebook_path  %>

クリックしてフォローすると、まったく同じエラーが発生します...

次のようなものを使用する必要があると思います（上記でリンクしたwikiに記載されているもの）：

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

そして、パススルー メソッドをラップして、params[:provider] 値に応じてアクションを適切なプライベート/保護メソッドに委譲します。

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
