在我的Rails应用程序上,我有一个行按钮,我想将其中一个放入一个下拉菜单中,该菜单将显示从db表中提取的项目,ruby代码可以工作,但我可以& #39; t让它显示为下拉。
这是红宝石代码:
<% @all_makes.each do |allMakesDisplay| %>
<a id="allMakesDisplay"><%= link_to allMakesDisplay.name, make_index_path(make_name: allMakesDisplay.name) %></a>
<% end %>
这是下拉行:
<div class="collapse navbar-collapse top-bar" id="bs-example-navbar-collapse-1">
<div class="row">
<div class="col-md-3">
<button class="btn btn-lg btn-secondary btn-block">
<a href="/">Home</a>
</button>
</div>
<div class="col-md-3">
<div class="dropdown">
<button class="btn btn-lg btn-secondary btn-block dropdown-toggle" type="button" data-toggle="dropdown">
<a href="/dealership/category/make">Makes</a>
<span class="caret"></span>
</button>
<% @all_makes.each do |allMakesDisplay| %>
<ul class="dropdown-menu">
<li>
<a href="<%= link_to allMakesDisplay.name, dealership_category_make_path(allMakesDisplay) %>"></a>
</li>
</ul>
<% end %>
</div>
</div>
<div class="col-md-3">
<button class="btn btn-lg btn-secondary btn-block">
<a href="blog.html">Models</a>
</button>
</div>
<div class="col-md-3">
<button class="btn btn-lg btn-secondary btn-block">
<a href="contact.html">My Portfolio</a>
</button>
</div>
</div>
</div>

MAKES
应该是下拉列表,应该返回12个项目。

答案 0 :(得分:1)
有一些事情正在发生:
#each
循环应位于<ul>
内。link_to
会创建一个锚标记<a>
,因此不应将其用作href
属性。 link_to
