我被困在论坛（包含的Stackoverflow）中似乎很好记录的问题中，但没有任何主题可以帮助我解决问题。 简而言之，我的远程调用控制器的所有应用程序都被触发两次。我在某处读到它可能是一个jQuery重复问题，但正如你在application.html.erb中看到的那样，application.js可能不是，因为jQuery只出现一次。在其他问题中出现的另一个解决方案是删除turbolink，但这并未解决我的问题。Rails 4.2.7提交远程表单的事件触发两次
我正面临的错误示例： 我有一个使用simple_form呈现的表单，它向操作提交GET请求。
<%= simple_form_for :create_answer, url: create_answer_path, remote: true do |f| %>
<b>Intenção</b>
<%= f.input :intents, :class=> "form-control", label: false%>
<b>Entidades</b>
<%= f.input :entities, :class=> "form-control", label: false%>
<b>Valores</b>
<%= f.input :values, :class=> "form-control", label: false%>
<b>Text</b>
<%= f.text_area :text, :class=> "form-control", label: false%>
<p class="text-center" style="margin-top:5px;">
<%= f.submit "Criar", :class => "btn btn-primary" %>
</p>
<% end %>
当提交操作的用户点击被触发两次，因为你可以在控制台日志中看到： 
因为我处理这个动作付费远程API，调用它两次是不可接受的。
