Question

在我的Rail 3.0.9应用程序中，我有routes.rb：

Myapp::Application.routes.draw do
  root :to => 'index#index'
  match '/:locale' => 'index#index', :locale => /ru|en/
  scope "(:locale)", :locale => /ru|en/ do
    resources :pages, :only => [:show]
...

在浏览器中转到/ path时，会显示404错误并在日志中显示消息：

它试图让奇怪的链接

No route matches {:locale=>#<NewsItem id: 20, title_ru: "event 2", description_ru: "<p>event description</p>", published_at: "2011-08-31 07:55:00", category: "events", created_at: "2011-08-31 07:55:26", updated_at: "2011-08-31 07:55:26", short_description_ru: "<p>descr</p>", title_en: nil, description_en: nil, short_description_en: nil>, :action=>"show", :controller=>"news_items"}

问题在于

<%= link_to l(news_item.published_at, :format => "%d.%m.%Y"), news_item %>

当我将其更改为

时

<%= link_to l(news_item.published_at, :format => "%d.%m.%Y"), :url => news_item %>

问题解决了。

1）为什么第一行的news_item被解释为：locale，而不是：url？

2）这是一个错误还是我错过了什么？

感谢所有人！

最后我找到了最佳解决方案：

def set_locale
  ...
  self.default_url_options[:locale] = params[:locale]
end

Answer 1

要解决这个问题，我们可以这样做：

def set_locale
  ...
  self.default_url_options[:locale] = params[:locale]
end

url中的locale前缀
