が動作していないハッシュルビ1.9.3p0（2011年10月30日改訂33570）[i686の-のLinux]。レール3.2.1 redirect_toオプションは、レールを使用
マイHelloController.rb＃sign_in方法 は、login_pageをレンダリングし、received.Ifの検証が失敗した資格証明書（フォーム値）を検証します。
検証が成功すると、資格情報が正しい見つかった場合、他のは
redirect_to "/games" # works
にリダイレクトゲーム＃インデックスにリダイレクトするユーザーの資格情報に を認証以下のいずれかが動作していない間
redirect_to {controller:"games", action:"index"} # Doesn't work
Output:
Routing Error
No route matches [GET] "/hello/sign_in"
しかし私UsersController.rb番号からリダイレクトするためのオプションの同じスタイルを使用してhttp://localhost:3000/hello/sign_inは細かい作品をリダイレクトし、メソッドを作成
後者の場合は、私のようなエラーが表示されます。検証かかわらず続いている間、私は作品
redirect_to "/hello/login_page", :notice => "User Id and Password don't match" # works
次のユーザーにユーザーID /パスワードがこのケースをmatch.Inないメッセージとログインページを表示する必要があります。また
資格情報が正しく見つからない場合
、redirect_to {controller:"hello", action:"login_page" notice: "User Id and Password don't match" } # Doesn't work
を動作しません。私はそのような行動の背後にある理由が何であるかを理解したいと思います。
routes.rbを
MyGames::Application.routes.draw do
resources :users do
# Collection route
collection do
get 'register' # creates the register_users_url and register_users_path route helpers.
end
end
resources :games
get "hello/index"
get "hello/login_page"
post "hello/sign_in"
end
HelloController.rb（手動で作成したコントローラ）
class HelloController < ApplicationController
skip_before_filter :require_login
skip_before_filter :require_admin_role
def index
# Show index page
end

self.page_title = "Log In"
end
def sign_in
# Validates the credentials.If validation fails
# render "login_page"
# Once validation is successful, authenticates the user credentials
# If credentials found correct, redirect to Games#index
# else redirect to "/hello/login_page"
# In my case following works
# redirect_to "/games", while
# the one below does not work
# redirect_to {controller:"games", action:"index"} # Doesn't work

# In this case it works correctly, by redirecting to '/games'
# when 'registration' action is found.
# The returned options are { controller: "games", action: "index" }

# redirect_to { controller: "games", action: "index" }
redirect_to validation_result_options
