Answer 1

You made a mistake in the :controller parameter in your form_for : 您在form_for的:controller参数中犯了一个错误：

<%= form_for root_path, :url => {:action => 'search', :controller=>"index"} do |f|%>

First of all, the :controller should be 'ads' since the search action is in the AdsController you provided a sample of. 首先， :controller应该是'ads'因为search动作在您提供的示例AdsController中。

Second, you're using form_for wrong. 其次，您使用form_for错误。 You're passing in two different paths, root_path and the :url hash. 您要传递两个不同的路径， root_path和:url哈希。 The first parameter should be the model you're trying to make a form for. 第一个参数应该是您要为其创建表单的模型。 But you don't need that here, you just want a search form, so use form_tag instead: 但是您在这里不需要那个，您只需要一个搜索表单，因此请使用form_tag ：

<%= form_tag :action => 'search', :controller=>"ads" do %>
