引导集成后Rails表单未提交答案

【问题标题】：Rails form not submitting after bootstrap integration引导集成后Rails表单未提交
【发布时间】：2016-07-28 01:20:10
【问题描述】：

我有一个功能齐全的注册表单。样式后（例如，下载模板的 html/css/js 并放入我的应用程序以使页面看起来更好）：

1) 我的注册页面停止工作。如果我按下提交，什么也不会发生。

我引用了这个问题：Rails form_for submit button not working 说要检查任何语法错误（我相信我没有）
我还阅读了有关 Javascript 缓存可能是问题的信息。我读到的两个 SO 问题谈到了 bootstrap.js 中的 e.preventDefault() 方法，但删除这些对我没有任何帮助。不确定我是否删除了正确的东西？

这是我正在使用的模板独有的 css：

在我的路线文件中，我确实有

devise_for :users

这是我的用户注册页面 new.html.erb

<h2>Sign up</h2>

<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
  <%= devise_error_messages! %>
   <div class="row">
            <div class="box">
                <div class="col-lg-12">
                    <hr>
                    <h2 class="intro-text text-center">Sign up form</h2>
                    <hr>
                        <div class="row">
                            <div class="form-group col-lg-3">
                                <%= f.label :email %>
                                <%= f.email_field :email, autofocus: true, class: "form-control", required: true %>
                            </div>
                            <div class="form-group col-lg-3">
                                <%= f.label :phone_number %> (In the form: 123456789)
                                <%= f.text_field :phone_number, autofocus: true, class: "form-control", required: true %>
                            </div>
                            <div class="form-group col-lg-3">
                                <%= f.label :password %>
                                <%= f.password_field :password, class: "form-control", required: true %>
                            </div>
                            <!-- <div class="clearfix"></div> -->
                            <div class="form-group col-lg-3">
                                <%= f.label :password_confirmation %>
                                <%= f.password_field :password_confirmation, class: "form-control", required: true %>
                            </div>
                            <div class="form-group col-lg-12">
                                <%= f.submit "Sign up", class: "btn btn-default" %>
                            </div>
                        </div>
                    </div>
              </div>
      </div>
<% end %>
<%= render "devise/shared/links" %>

此页面显示正常，但当我按下提交按钮时没有任何反应。

这是我的 application.js

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts,
// or any plugin's vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require jquery
//= require jquery_ujs 
//= require turbolinks
//= require bootstrap-sprockets
//= require rails.validations
//= require_tree .

还有我的 application.css.scss

/*
 * This is a manifest file that'll be compiled into application.css, which will include all the files
 * listed below.
 *
 * Any CSS and SCSS file within this directory, lib/assets/stylesheets, vendor/assets/stylesheets,
 * or any plugin's vendor/assets/stylesheets directory can be referenced here using a relative path.
 *
 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
 * compiled file so the styles you add here take precedence over styles defined in any styles
 * defined in the other CSS/SCSS files in this directory. It is generally better to create a new
 * file per style scope.

有什么想法吗？

编辑以包含基于 cmets 的信息： 通过rails s 启动我的本地服务器。 Javascript 控制台抛出一个错误：

[Error] Failed to load resource: the server responded with a status of 500 (Internal Server Error) (bootstrap-theme.css.map, line 0)

编辑 2：我从应用程序目录中删除了所有引导文件，并且只导入了 gem——现在控制台中完全没有错误。只是一些关于意外 CSS 令牌的警告（这只是浏览器兼容性问题：https://www.quora.com/Why-does-Safari-display-three-warnings-in-Bootstrap），但注册按钮仍然没有任何作用。

【问题讨论】：

logs/development.log 中有什么内容？如果您在浏览器中打开开发者工具，提交时是否在控制台中出现任何 Javascript 错误？
浏览器控制台中的任何内容？另外：你是如何启动本地服务器的？
已编辑问题以回答这两个问题。谢谢大家！

【解决方案1】：

没关系-- JS 缓存从来都不是问题。我在 application.html.erb 中没有正确生成——我放入应用程序布局的 cmets 继续进入我的表单元素。当我检查我的页面源代码并看到 html 标记被注释掉时，我注意到了这一点。感谢大家的帮助！
