如何在 url Rails 中编码 (.) 点

我有如下所示的路线来删除/列出用户。

map.connect 'developer/:user_name/delete',:controller=>"developers",:action=>"delete",:method=>:delete  

map.connect 'developer/:user_name/list',:controller=>"developers",:action=>"list",:method=>:get

通过用 %2E 编码点来列出用户时，我可以看到成功响应

http://localhost:3000/developer/testuser%2Ehu/list

但是，当尝试删除包含点（.）的用户时，会抛出404错误。

http://localhost:3000/developer/testuser%2Ehu/delete, how to fix this issue.

阿夫迪·格林就这个主题写道：http://avdi.org/devblog/2010/06/18/rails-3-resource-routes-with-dots-or-how-to-make-a-ruby-developer-go-a-little-bit-疯狂的/ http://avdi.org/devblog/2010/06/18/rails-3-resource-routes-with-dots-or-how-to-make-a-ruby-developer-go-a-little-bit-insane/

你会想做这样的事情（完全归功于 avdi）

  resources :users, :constraints => { :id => /.*/ } do
    resources :projects
  end

该帖子的评论者说你还可以这样做：

resources :users, :id => /.*/
