Rubyonrails 将根 url 重定向到 Rails 应用程序中的其他位置

我有这样的路由:

map.namespace 'prepayments', :path_prefix => '/:locale/prepayments'  do |prepayment|
  prepayment.root  :controller => 'login', :namespace => 'prepayments'
  ...
end

map.redirect '/', :controller => 'prepayments/login' # this is not working
# I tried also
map.root :controller => 'prepayments/login'

我想得到的是，在键入www.example之后.它会将我重定向到www.example.com/en/预付款.

早些时候，当我使用上面例子中的map.root时，它只是停留在www.example上.com并呈现了正确的视图(但没有:locale，效果很好)，后来我在路由中添加了:locale，从那时起，我的视图(使用某种形式)无法正常工作.我得到一个错误，它找不到表单对应的路径——这是正确的，因为我没有通过任何:locale.

那么，如何将root重定向到另一个页面？它可能需要生成正确的路径并通过http 302进行传递.

map.root :controller => 'prepayments/login', :my_locale => 'en'

         prepayments_root  /:locale/prepayments               {:controller=>"prepayments/login", :action=>"index"}
       prepayments_create  /:locale/prepayments/send_email    {:method=>:post, :controller=>"prepayments/login", :action=>"send_email"}
         prepayments_home  /:locale/prepayments/home          {:controller=>"prepayments/prepayments", :action=>"home"}
         prepayments_save  /:locale/prepayments/save          {:controller=>"prepayments/prepayments", :action=>"save"}
        prepayments_agree  /:locale/prepayments/agree         {:controller=>"prepayments/prepayments", :action=>"agree"}
     prepayments_disagree  /:locale/prepayments/disagree      {:controller=>"prepayments/login", :action=>"logout"}
      prepayments_payment  /:locale/prepayments/payment       {:controller=>"prepayments/prepayments", :action=>"payment"}
prepayments_payment_email  /:locale/prepayments/payment_email {:controller=>"prepayments/prepayments", :action=>"payment_email"}
                           /:locale/prepayments/:uid          {:controller=>"prepayments/login", :action=>"verify"}
                 redirect  /                                  {:controller=>"prepayments/login", :action=>"index"}

我试着按照加勒特提议的方式go 做，结果成功了.我改变了路由:

map.redirect '/', :controller => 'prepayments/login', :action => 'welcome'

并在控制器中添加了欢迎方法:

def welcome
  redirect_to prepayments_root_path(:locale => 'en')
end

它可以按照我的要求工作(所以它可以在我的浏览器中更改url).

另一种方法是像这样改变路由:

map.root :controller => 'prepayments/login', :locale => 'en'

它也可以工作，但不会重定向(不会更改浏览器中的url).我不确定是否有map.redirect这样的选项.我在www上的示例中找到了它，但我也找到了添加此类功能的插件.

谢谢你的帮助！
