なぜデフォルトロケールが機能しないのですか？自分のアプリケーションのコントローラで

Question

、私はフィルタ以前のようにロケール処理を強制しています：

before_filter :set_locale 

def set_locale 
    #I18n.default_locale is en 
    I18n.locale = extract_locale_from_tld || I18n.default_locale 
end 

def extract_locale_from_tld 
    parsed_locale = params[:locale] || ((lang = request.env['HTTP_ACCEPT_LANGUAGE']) && lang[/^[a-z]{2}/]) 
    #so, english is the default language. 
    parsed_locale= 'en' if parsed_locale.nil? 
    I18n.available_locales.include?(parsed_locale.to_sym) ? parsed_locale : nil 
end 

しかし、私はhttp://localhost:3000/ko/labを訪問しようとした場合、それは最終的にエラー404あるルーティングエラーになります。

何かアドバイス：

ルーティングエラーになり、次の突き止めのうち任意のロケール

デフォルトはローカルの作業を行いますが、あなたが/:locale/labと一致するルートを持っていません。それは簡単です。

scopeを使用してローカライズされたルートを作成することはできますが、Railsではこれを行いません。

scope '(:locale)', locale: /#{I18n.available_locales.join('|')}/ do 
    get '/' => 'home#home' # this will map /en to home#home 
    get 'lab' => 'experiments#lab' 
    # ... 
end 

これはおそらく、その最大限にリソースヘルパーを使用して、本当に厄介なroutesファイルをリファクタリングするには良い時間です：

resources :experiments do 
    member do 
    get :info_edit 
    # ... 
    end 
end
