Question

在我的应用程序控制器中，我强制将语言环境处理作为前置过滤器：

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

但是，如果我尝试访问http://localhost:3000/ko/lab，则会导致路由错误，最终会导致错误404。

以下定位中的任何区域设置都将导致路由错误：

有什么建议吗？

默认本地确实有效，但您没有匹配/:locale/lab的路线。就这么简单。

您可以使用scope创建本地化路由 - Rails不会为您执行此操作。

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

这可能是通过充分利用资源助手重构一个非常混乱的路由文件的好时机：

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

为什么默认语言环境不起作用？
