Mic*_*V69 7 rails-routing rails-engines ruby-on-rails-3.2 rails-i18n
我有一个应用程序(my_test_app),内置了i18n支持.目前,有两种语言文件可用,FR&EN,如果我在它们之间来回切换,一切正常,因为我希望看到非引擎功能,如用户索引/显示/编辑/删除(ISED)选项.
在my_test_app中,我安装了一个Rails引擎(my_engine),它有一个控制器和模型集(engine_job).所以,一个可行的URL应该是
http://0.0.0.0:3000/fr/my_engine/engine_job
然而,无论我选择何种语言,它总是出现在EN中.检查参数显示:
--- !ruby/hash:ActiveSupport::HashWithIndifferentAccess
locale: fr
action: index
controller: my_engine/engine_job
然而,所选择的翻译是EN.
my_test_app route.rb:
MyTestApp::Application.routes.draw do
scope "(:locale)", locale: /#{I18n.available_locales.join("|")}/ do
mount MyEngine::Engine, at: "/my_engine"
end # scope locale
match '*path', to: redirect("/#{I18n.default_locale}/%{path}"), constraints: lambda { |req| !req.path.starts_with? "/#{I18n.default_locale}/" and !req.path == "/#{I18n.default_locale}/"}
match '', to: redirect("/#{I18n.default_locale}/")
end
my_engine route.rb:
MyEngine::Engine.routes.draw do
resources :my_jobs
end
耙路线:
my_engine (/:locale)/my_engine MyEngine::Engine {:locale=>/en|fr/}
/*path(.:format) :controller#:action

Routes for MyEngine::Engine {:locale=>/en|fr/}:
engine_jobs GET /engine_jobs(.:format) my_engine/engine_jobs#index
POST /engine_jobs(.:format) my_engine/engine_jobs#create
new_engine_job GET /engine_jobs/new(.:format) my_engine/engine_jobs#new
edit_engine_job GET /engine_jobs/:id/edit(.:format) my_engine/engine_jobs#edit
engine_job GET /engine_jobs/:id(.:format) my_engine/engine_jobs#show
PUT /engine_jobs/:id(.:format) my_engine/engine_jobs#update
DELETE /engine_jobs/:id(.:format) my_engine/engine_jobs#destroy
此外,在引擎中单击的任何链接都将语言设置为EN.一些网络搜索没有明确说明这里可能发生的事情,因为我能找到的所有i18n示例都不涉及已安装的引擎.
编辑:显示设置默认语言环境的代码my_test_app/app/controllers/application_controller.rb:
class ApplicationController < ActionController::Base
protect_from_forgery
helper MyEngine::Engine.helpers
ActiveRecord::Base.verify_active_connections!
before_filter :set_locale
private
def set_locale
I18n.locale = params[:locale] || I18n.default_locale
Rails.application.routes.default_url_options[:locale]= I18n.locale
logger.debug "My_Test_App: default_url_options is passed options: #{Rails.application.routes.default_url_options.inspect}\n"
# current_user.locale

end # set_locale
end # class ApplicationController

申请路线http://0.0.0.0:3000/en/users与"locale"=>"en".帮助者创建的引擎路线看起来像http://0.0.0.0:3000/my_engine?locale=en/engine_jobs和yeilds No route matches [GET] "/my_engine".

所以,问题是我需要对我的路线或引擎进行哪些更改才能使其按预期工作？
提前感谢您的时间和建议!
我正在使用带有 I18n 的引擎，它工作得很好。我创建了一个虚拟 Rails 应用程序来尝试您的场景。据我所知，更改 URL 内的区域设置可以与 Rails 应用程序中定义的路由配合使用：
我的路线：
Bar::Application.routes.draw do
root 'posts#index'
scope "(:locale)", locale: /#{I18n.available_locales.join("|")}/ do
resources :posts, only: :index
end
end
我可以使用以下命令更改 I18n 语言环境：
http://localhost:3000/fr/posts
http://localhost:3000/en/posts
我认为您的问题是当您想要转到任何引擎的路线时，因为您没有设置 I18n 区域设置开关。见下图：
engine_jobs GET /engine_jobs(.:format)
然后，即使/engine_jobs您在 URL 中指定了语言环境，也会设置 I18n 默认语言环境 ( en)：
def set_locale
I18n.locale = params[:locale] || I18n.default_locale
# ...
end
当使用你的引擎路线时，params[:locale]是nil
将相同的逻辑添加到引擎的路线中：
config/routes.rb
MyTestApp::Application.routes.draw do
mount MyEngine::Engine, at: "/my_engine"
match '*path', to: redirect("/#{I18n.default_locale}/%{path}"), constraints: lambda { |req| !req.path.starts_with? "/#{I18n.default_locale}/" and !req.path == "/#{I18n.default_locale}/"}
match '', to: redirect("/#{I18n.default_locale}/")
end
your_engine/config/routes.rb
MyEngine::Engine.routes.draw do
scope "(:locale)", locale: /#{I18n.available_locales.join("|")}/ do
resources :my_jobs
end
end
mount MyEngine::Engine, at: "/my_engine"只告诉 Rails“加载”所有引擎路线。如果您需要添加约束、范围、命名空间或其他任何内容，您应该使用通常的 Rails 方式来执行此操作，但在引擎的路由文件中。
最后，您需要application_controller.rb使用以下内容更新您的（主应用程序+引擎）：
class ApplicationController < ActionController::Base
def url_options
{ locale: I18n.locale }
end
def set_locale
I18n.locale = params[:locale] || I18n.default_locale
Rails.application.routes.default_url_options[:locale]= I18n.locale
end
end
