我的研究路线有问题。他们指责这个错误：

ActionController::UrlGenerationError in Devise::Sessions#new
No route matches {:action=>"search", :controller=>"devise/index"}

我的广告模型：

Answer 1

您在:controller中的form_for参数中犯了错误：

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

首先，:controller应为'ads'，因为search操作位于您提供样本的AdsController中。

其次，您使用form_for错误。您通过两个不同的路径root_path和:url哈希传递。第一个参数应该是您尝试制作表单的模型。但是你不需要这里，你只需要一个搜索表单，所以请改用form_tag：

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

http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#method-i-form_tag

没有路线匹配{：action =＆gt;＆＃34;搜索＆＃34;，：controller =＆gt;＆＃34;设计/索引＆＃34;}
