rails新手,关于form和url附加参数的问题

Question

代码如下
<% form_tag :action=>:search,:controller=>:system do%>
<%=text_field_tag:keyword%>
<%=select_tag :option,["标签","同盟","用户"]%>
<%=submit_tag '搜索'%>
<%end%>
点击搜索后转到url都是/search
怎样处理能让他变成/search?option=xxx&keyword=xxx的形式?

Answer 1

怎么可能?

<% form_tag :action=>:search,:controller=>:system do%>
变成
[color=red]<% form_tag url_for(:action=>:search,:controller=>:system), :method => "get" do%> [/color]
