ruby on Rails 中的 Bootstrap 模式不起作用

我正在尝试实现一个模式来为我的应用程序创建新用户。由于某种原因无法使其工作。

这段代码只是淡入淡出，并且没有显示任何模式，我不明白为什么。事实上，我正在使用与此答案完全相同的代码如何使用 link_to 添加引导模式，以便链接内容在模式中打开？

<%= link_to "Open modal", "#myModal", :class => "btn", "data-toggle" => "modal" %>
      <!-- Modal -->
      <div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
          <h3 id="myModalLabel">Modal header</h3>
        </div>
        <div class="modal-body">
          <p>One fine body…</p>
        </div>
        <div class="modal-footer">
          <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
          <button class="btn btn-primary">Save changes</button>
        </div>
      </div>

My gems:

gem 'rails',        '5.0.2'
# Use mysql as the database for Active Record
gem 'mysql2', '>= 0.3.18', '< 0.5'
gem 'faker',          '1.6.6'
gem 'will_paginate',           '3.1.0'
gem 'bootstrap-will_paginate', '0.0.10'
gem 'bcrypt',         '3.1.11'
gem 'bootstrap-sass', '3.3.6'
gem 'puma',         '3.4.0'
gem 'sass-rails',   '5.0.6'
gem 'uglifier',     '3.0.0'
gem 'coffee-rails', '4.2.1'
gem 'jquery-rails', '4.1.1'
gem 'turbolinks',   '5.0.1'
gem 'jbuilder',     '2.4.1'

线下方app/assets/javascripts/application.js

//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require bootstrap-sprockets

And my scss

@import "bootstrap-sprockets";
@import "bootstrap";

您需要删除hide类来自#myModal模态，因为这给了它一个display: none !importantCSS 规则，这就是为什么你看不到它：

检查一下：

<div id="myModal" class="modal fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
        <h3 id="myModalLabel">Modal header</h3>
      </div>
      <div class="modal-body">
        <p>One fine body…</p>
      </div>
      <div class="modal-footer">
        <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
        <button class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

最有可能的是你需要包裹你的.modal-header在一个<div class="modal-dialog" role="document"> and a <div class="modal-content">看到你的它“很好”。
