在Ruby on Rails中添加ID或类？

Question

我对搜索表单有以下代码，但是如何将ID或类添加到提交按钮？

<% form_tag '/wine/search/', :method => 'get' do %> 
    <%= label_tag "Search" %> 
    <%= text_field_tag :search_string, params[:search_string] %> 
    <%= submit_tag "Go" %> 
<% end %> 

感谢

submit_tag "Go", :class => "some_class" 
submit_tag "Go", :id=> "some_id" 

从Rails API FormTagHelper
