Question

我陷入了一个似乎在论坛（包括Stackoverflow）中有详细记录的问题，但这些主题都没有帮助我解决问题。简而言之，在应用程序中，我对控制器的远程调用被触发两次。我在某处读到它可能是一个jQuery重复问题，但正如你在我的application.html.erb和application.js中看到的那样可能不是，因为jQuery出现一次。其他问题中出现的另一个解决方案是删除turbolinks，但这并没有解决我的问题。

我面临的错误示例：我有一个使用simple_form呈现的表单，它向一个动作提交一个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 %>

当用户点击提交时，操作会被触发两次，您可以在控制台日志中看到：由于我正在处理此操作的付费远程API，因此将其调用两次将是不可接受的。

任何人都可以帮助我吗？感谢

Answer 1

根据您提供的代码段，您的操作看起来不会触发两次，而不是您的日志条目重复。

rails_12factor可能是罪魁祸首，看起来你在Gemfile中列出了两次。这会将您的日志输出到stdout和Rails记录器，这样它们就会在您的终端中出现两次。

删除gem "rails_12factor"并保留gem 'rails_12factor', group: :production。然后bundle并重新启动Rails服务器，问题应该消失。
