如何从 link_to 内容打开引导模式？

Question

我正在创建一个 reddit 克隆，然后单击标题上的登录或注册文本会打开一个模式，供用户输入其凭据。

我在这里创建了一个模态部分：

<div class="modal fade" id="popUpWindow">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="col-md-6">
                <!-- header -->
                <div class="modal-header">
                    <button type ="button" class="close" data-dismiss="modal">&times;</button>
                    <h3 class="modal-title">CREATE A NEW ACCOUNT</h3>
                </div>
                <!-- body (form) -->
                <div class="modal-body">
                    <form role="form">
                        <div class="form-group">
                            <input type ="username" class="form-control" placeholder="choose a username">
                        </div>
                        <div class="form-group">
                            <input type ="password" class="form-control" placeholder="password">
                        </div>
                        <div class="form-group">
                            <input type ="password_confirmation" class="form-control" placeholder="verify password">
                        </div>
                        <div class="form-group">
                            <input type ="email" class="form-control" placeholder="email">
                        </div>
                    </form>
                </div>
                <!-- button -->
                <div class="modal-footer">
                    <button class="btn btn-primary btn-block">SIGN UP</button>
                </div>
            </div>

            <div class="col-md-6">
                <!-- header -->
                <div class="modal-header">
                    <button type ="button" class="close" data-dismiss="modal">&times;</button>
                    <h3 class="modal-title">LOG IN</h3>
                </div>
                <!-- body (form) -->
                <div class="modal-body">
                    <form role="form">
                        <div class="form-group">
                            <input type ="username" class="form-control" placeholder="username">
                        </div>
                        <div class="form-group">
                            <input type ="password" class="form-control" placeholder="password">
                        </div>
                    </form>
                </div>
                <!-- button -->
                <div class="modal-footer">
                    <button class="btn btn-primary btn-block">LOG IN</button>
                </div>
            </div>

        </div>
    </div>
</div>

现在我正在尝试从此处的标头部分访问此模式代码：

<header class="navbar navbar-fixed-top navbar-inverse">
    <div class="container">
    <%= link_to "reddit", root_path , :id => 'logo' %>
        <nav>
            <ul class="nav navbar-nav navbar-right">
                <li>
                <%= link_to 'Sign up or log in', "#", data: {toggle: "popUp", target: "#popUpWindow"} %>
                </li>
            </ul>s
        </nav>
    </div>
</header>

我认为这一行将通过其 id popUpWindow 成功打开模式：<%= link_to 'Sign up or log in', "#", data: {toggle: "popUp", target: "#popUpWindow"} %>

没有出现任何错误，但单击 link_to 内容不会触发任何内容打开。

在 application.js 我有：

//= require jquery

//= require bootstrap

应该是 {:toggle => "modal", :target => "#popUpWindow"} %> 代替吗？
