Question

我遇到了一个奇怪的错误，我不想再解决这个问题但要理解。

在最近添加我们主页的英文版本时，我发现我无法像在德国语言环境中那样生成这些内容：

2.3.0 :023 > I18n.available_locales
=> [:de, :en]

2.3.0 :019 > apps_path(locale: :de)
=> "/de/apps"

2.3.0 :020 > apps_path(locale: :en)
ActionController::UrlGenerationError: No route matches 
{:action=>"apps", :controller=>"pages", :locale=>:en} missing required keys: [:locale]

正如我所说，我可以使用url_for或 - 在坚持我们的示例apps_en_path时解决这个问题。

但我想知道导致这个奇怪问题的原因。

编辑

git bisect会话让我发现自从我将route-translater gem添加到我的项目后就发生了这种情况。除了这个问题，它对我们来说也很好。

我有这个设置（在development.rb中）：

# RouteTranslator.config
config.force_locale = true
config.locale_param_key = :locale

我的routes.rb：

require_relative "#{Rails.root}/app/route_constraints/can_access_devops"

Rails.application.routes.draw do
  get 'health', to: 'health#show'

  # Redirect requests with trailing 'null'
  get '/*path/null', to: redirect('/%{path}')

  namespace :admin do
    root to: redirect('/admin/magazine_articles')

    resources :jobs
    resources :users
    resources :magazine_categories
    resources :magazine_articles
    resources :media_assets
    resources :advertisements do
      member do
        get 'preview'
      end
    end

    namespace :devops do
      authenticate :user do
        constraints CanAccessDevOps do
          mount PgHero::Engine, at: '/pghero'
        end
      end
    end
  end

  scope '/:locale', locale: /#{I18n.available_locales.join("|")}/ do
    root to: 'pages#home'

    localized do
      devise_for :users, controllers: { sessions: 'sessions' }

      # the packaging has a link that should point to cockpit

Answer 1

我快速完成了你的路线，我遇到了与 de 路线类似的问题。我认为您获得的 apps_path 路由只允许您的默认语言环境作为参数。

添加以下option为我解决了这个问题：

SELECT `title`, `text` FROM `news` ORDER BY `datetime` DESC LIMIT 5

这将正确生成未本地化的路由，因此您可以将多个区域设置传递给 apps_path 。

Answer 2

除了localized块之外，没有任何东西对我来说非常可疑。这是来自某些宝石吗？如果是，apps_path(locale: 'en')请求在localized阻止之外工作？

调整路径文件后，您可以在控制台上使用Rails.application.routes.url_helpers.app_path(locale: :en)进行测试。
