ruby-on-rails-3 - Rails 国际化 (I18n) : locale in the url

Question

我是 Rails 新手(使用 3.2.1)，我正在关注 rails guides 上的 i18n-guide .

我在这部分遇到问题:

You probably want URLs to look like this: www.example.com/en/books (which loads the English locale) and www.example.com/nl/books (which loads the Netherlands locale). This is achievable with the “over-riding default_url_options” strategy from above: you just have to set up your routes with path_prefix option in this way

但是当我在 View 中使用 <%= products_path %> 时，它会返回: /products?locale=en
我希望它返回 /nl/产品

当我在浏览器中输入 url(例如 localhost:3000/nl/products)时，页面会显示正确的语言环境。

我错过了什么？

应用 Controller :

class ApplicationController < ActionController::Base
  before_filter :set_locale

  def set_locale
    I18n.locale = params[:locale] || I18n.default_locale
  end

  def default_url_options(options = {})
    { :locale => I18n.locale }
  end
end

路线:

  scope "/:locale" do
    resources :products
  end

  match '/:locale' => 'products#index'

耙路线:

    products GET    /products(.:format)                  products#index
             POST   /products(.:format)                  products#create
 new_product GET    /products/new(.:format)              products#new
edit_product GET    /products/:id/edit(.:format)         products#edit
     product GET    /products/:id(.:format)              products#show
             PUT    /products/:id(.:format)              products#update
             DELETE /products/:id(.:format)              products#destroy
             GET    /:locale/products(.:format)          products#index
             POST   /:locale/products(.:format)          products#create
             GET    /:locale/products/new(.:format)      products#new
             GET    /:locale/products/:id/edit(.:format) products#edit
             GET    /:locale/products/:id(.:format)      products#show
             PUT    /:locale/products/:id(.:format)      products#update
             DELETE /:locale/products/:id(.:format)      products#destroy
                    /:locale(.:format)                   products#index
        root        /                                    products#index

使用 path_prefix 怎么样？选项改为

def default_url_options(options = {})
  { :path_prefix => I18n.locale }
end
