【问题描述】：

我正在尝试创建一个简单的搜索表单，将用户转到单独的“结果”页面。

我对 index.html.erb 的看法如下：

<%= simple_form_for results_path, method: :get, html: { class: "form-inline justify-content-center" } do |f| %>

    <%= f.select :what, options_for_select([['Happy Hours Anywhere','Anywhere'],['After Work Drinks','After Work Drinks'],['Somewhere to Relax with Friends', 'Relaxing with Friends'], ['A Club Night','Club Night'], ['Somewhere for Date Night','Date Night'], ['A Place to Watch Sports', 'Watching Sports']]),{} ,:class => "form-control select-box font-lightweight"  %>

    <%= f.select :datetime, options_for_select(dates_for_search_select.each_with_index.map{|d, i| [d[1],d[0]]}), {}, :class => "form-control select-box font-lightweight" %>

    <%= f.select :time, options_for_select(times_for_search_select.each_with_index.map{|d, i| [d[1],d[0]]}), {}, :class => "form-control select-box font-lightweight" %>

    <%= f.button :submit, 'Discover', :class => 'btn btn-block btn-danger btn-embossed top-margin ' %>
<%end%>

我已经创建了我的“结果”路线，如下所示：

Rails.application.routes.draw do
  resources :offers
  resources :venues
    get 'home/results' => 'home#results', :as => :results
    get 'home/index'
  devise_for :users
  root to: "home#index"    
end

但是，当我生成 HTML 生成的表单时，操作会继续路由回索引页面：

<form class="simple_form form-inline justify-content-center" novalidate="novalidate" 
 action="/home/index" accept-charset="UTF-8" method="get"><input name="utf8" type="hidden" value="✓">

</form>

我错过了什么？

【问题讨论】：

尝试用这个得到“结果”，到：“home#results”

【解决方案1】：

simple_form_for 要求一个对象作为第一个参数（类实例或符号）。然后您可以添加url: articles_path，就像添加普通的form_for 一样。见simple form source code

所以你需要这样一行：

<%= simple_form_for :results, url: results_path, method: :get, html: { class: "form-inline justify-content-center" } do |f| %>
