似乎我无法弄清楚如何在 Michael Hartl railstutorial Sample App 的导航栏菜单上显示“登录”按钮。
我目前在 9.3 并且测试失败。我试着回顾每个不同的章节，找出我在哪里丢失了登录按钮或如何......我已经重写了很多代码，希望能解决这个问题。无论如何，这是我拥有的代码。
我还注意到，在以登录用户身份注销后，我的下拉菜单不会继续显示。
无论如何..
我的 _header.html.erb
<header class="navbar navbar-fixed-top navbar-inverse">
<div class="navbar-inner">
<div class="container">
<%= link_to "sample app", root_path, id: "logo" %>
<nav>
<ul class="nav pull-right">
<li><%= link_to "Home", root_path %></li>
<li><%= link_to "Help", help_path %></li>
<% if signed_in? %>
<li><%= link_to "Users", 'users_path' %></li>
<li id="fat-menu" class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown">
Account <b class="caret"></b>
</a>
<ul class= "dropdown-menu">
<li><%= link_to "Profile", current_user %></li>
<li><%= link_to "Settings", edit_user_path(current_user) %></li>
<li class="divider"></li>
<li>
<%= link_to "Sign out", signout_path, method: "delete" %>
</li>
</ul>
</li>
<% else %>
<li><% link_to "Sign in", signin_path %></li>
<% end %>
</ul>
</nav>
</div>
