当我将数组列表作为类别项并传递到引导程序材料中时,只需知道如何在rails视图中添加ransack代码
导轨代码
在起始行搜索路径代码之上
<%= search_form_for @search, url: events_path do |f| %>
下拉列表代码下拉列表(不带acksack),可提供带有正确下拉列表的输出
<div class="col">
<div class="dropdown" id="dropdown">
<p class="selected" id="selected"><span>Filter By Category1</span> <i class="material-icons">keyboard_arrow_down</i></p>
<ul class="dropdown-list" id="dropdown-list">
<a href="/events">
<li>All Events </li>
<% @category_list.each do |cat| %>
<li class="selected" id="list"> <%= cat.name %></li>
<% end %>
</ul>
</div>
</div>
我正在尝试添加ransack,这不会显示我的列表
<div class="col">
<div class="dropdown" id="dropdown">
<%= f.select :category_name_eq, class: "selected" %>
<ul class="dropdown-list" id="dropdown-list">
<a href="/events">
<li>All Events </li>
<% @category_list.each do |cat| %>
<li class="selected" id="list"> <%= cat.name %></li>
<% end %>
</ul>
</div>
</div>

您可以使用下面的列表,
如果允许空白选项,则应添加include_blank:true作为下面的示例
<div class="row form-group">
<%= f.label "Filter By Category1 <i class="mi md-18">arrow_downward</i>".html_safe, :class => 'col-form-label col-sm-3' %>
<div class="col-sm-9">
<%= f.select :category_name_eq,
@category_list.all.map { |cat| [cat.name, cat.name] },
{ include_blank: true }, { class: 'form-control' } %>
</div>
</div>
