jQuery Rails 5提交表单两次

我知道人们对此提出了很多要求，但是没有一个答案对我有用。我在使用JQuery提交的Rails 5中有一个表单（用于添加有关视频的信息）。现在的问题是，表单被提交了两次，每个条目实际上被创建了两次（两次发布请求），但是具有不同的ID。

一些答案​​说jquery被两次包含了，这是因为我在assets/javascripts/application.js中

//= require jquery
//= require rails-ujs
//= require jquery_ujs
//= require_tree .

有人告诉我删除//= require jquery_ujs，因为'rails_ujs'已经需要它。但是，问题仍然存在。使表单一次提交的唯一方法是删除//= require jquery

因此，此表单在assets/javascripts/application.js

中两次提交了表单 
//= require jquery
//= require rails-ujs
//= require_tree .

尽管assets/javascripts/application.js中的表单一次提交表单，但是某些使用jquery的组件（例如下拉列表）不再起作用（正常，因为它不存在），但是我感到困惑，因为表单仍然可以提交。 

//= require rails-ujs
//= require_tree .

这是我创建视频的创建方法

    def create
        params[:rubric][:author] = session[:current_user_name]
        rubric = Rubric.new(rubric_params)
        @video =  rubric.create_video(video_params)
        @video.lastEdit = session[:current_user_name]
        @video.save
        flash[:notice] = "Video has been created and has following id:'#{@video.id}'"
        redirect_to video_path(@video)
      end

表单看起来像这样

 <form action="/videos" method="POST" class="ui form" style="margin:0">
// A bunch of fields
  <button style="color: white; margin: 20px 0 20px 0" class="ui huge submit blue basic button">Create</button>

如您所见，表格非常简单。 这是开发日志。请注意两个发帖请求
