Ruby on Rails：下载文件名中包含多个点的文件（使用Carrierwave上传）

Question

The view:

<%= link_to File.basename(attachment.attachment.url), "/uploads/#{attachment.id}/#{File.basename(attachment.attachment.url)}" %>

The controller:

# ...
  def download
    path = "#{Rails.root}/uploads/"+ params[:id] + "/"+ params[:basename] +"."+ params[:extension]

    send_file path, :x_sendfile=>true
  end
# ...

The route:

match "/uploads/:id/:basename.:extension", :controller => "attachments", :action => "download", :conditions => { :method => :get }

The error is get is:

Routing Error

No route matches [GET] "/uploads/38/Screen_shot_2012-02-18_at_2.20.49_PM.png"
