身元確認ログインのOmniAuth :: Error（invalid_credentials）を処理​​します

Question

私はOmniAuth Identityを通常のログインに使用しています。 Rails 3.2.3とRuby 1.9.3p194です。現在

、既存のユーザーが無効な資格情報を使用してログインしようとしたとき、私は次のエラーを取得する：

Started POST "/auth/identity/callback" for 127.0.0.1 at 2012-07-12 17:00:03 -0400 
(identity) Callback phase initiated. 
    Identity Load (0.1ms) SELECT "identities".* FROM "identities" WHERE "identities"."email" = 'test' LIMIT 1

私は、このフォームにエラーハンドラや救助のいくつかの並べ替えを追加できるようにしたいのですが、しかし、私はどのようにするか分からない。ここでは、フォームです：

セッション/ new.html.haml

%p 
    %strong Don’t use these services? 
    = link_to "Create an account", new_identity_path 
    or login below 

= form_tag "/auth/identity/callback" do 
    .field 
    = label_tag :auth_key, "Email" 
    %br 
     = text_field_tag :auth_key 
    .field 
    = label_tag :password 
    %br 
     = password_field_tag :password 

マイセッションコントローラ：

sessions_controller.rb

class SessionsController < ApplicationController 

    def create 
    debugger 
    user = User.from_omniauth(env["omniauth.auth"]) 
    puts "ENVIRONMENT VARIABLE: #{env["omniauth.auth"].inspect}" 
    puts "This is the user id: #{user.id}" 

    session[:user_id] = user.id 
    redirect_to root_url, notice: "Signed in!" 

    end 

    def destroy 
    session[:user_id] = nil 
    redirect_to root_url, notice: "Signed out!" 
    end 

    def failure 
    redirect_to signup_path, alert: "Authentication failed, please try again." 
    end 

end 
    .actions= submit_tag "Login" 

私のユーザモデル：

user.rb

class User < ActiveRecord::Base 
    attr_accessible :email, :name, :provider, :uid 

    validates_presence_of :email 
    validates_uniqueness_of :email 
    validates_format_of :email, :with => /^[-a-z0-9_+\.]+\@([-a-z0-9]+\.)+[a-z0-9]{2,4}$/i 

    def self.from_omniauth(auth) 
    where(auth.slice("provider", "uid")).first || create_from_omniauth(auth) 
    end 

    def self.create_from_omniauth(auth) 

    puts "Auth object: #{auth.inspect}" 
    create! do |user| 
     user.provider = auth["provider"] 
     user.uid = auth["uid"] 
     user.name = auth["info"]["name"] 
     user.email = auth["info"]["email"] 
     user.admin = false 
    end 


    end 

end 

マイOmniAuthの設定ファイル：

私は＃はアクションを作成し、私のセッションの最後に、このような何かを追加しようとした

OmniAuth.config.logger = Rails.logger 

Rails.application.config.middleware.use OmniAuth::Builder do 
    provider :github, ENV['6c268d450fb1149afc3d'], ENV['1dba63b45a0c8b7e62dea9fc5c9a8f69bf6142b1'] 
    provider :identity, on_failed_registration: lambda { |env| 
    IdentitiesController.action(:new).call(env) 
    } 
end 

omniauth.rb：

rescue OmniAuth::Error 
    flash[:error] = "invalid credentials" 
    redirect_to signup_path 

しかし、私はまだ無効なログインで元のエラーメッセージを得ました。無効なOmniAuth Identityログインを処理するにはどうすればよいですか？

を更新：sessions_controller.rbする

OmniAuth.config.on_failure = Proc.new { |env| 
    OmniAuth::FailureEndpoint.new(env).redirect_to_failure 
} 

故障方法：溶液がomniauth.rbを次のコードを追加する

た

def failure 
    redirect_to login_path, alert: "Authentication failed, please try again." 
end 

（そして義務的なサーバの再起動）

これは意図的な開発モードの結果であるように見えます。 FAQの "OmniAuth::FailureEndpoint does not redirect in development mode"までスクロールします。
