ruby-on-rails - 如何在 Rails 表单选择标签中添加数据属性？

Question

我找到了这个 Bootstrap Select项目及其gem for Rails .我想在 select 标签中实现搜索。

我检查元素，这里是 HTML 源代码:

<select class="selectpicker" data-live-search="true">
  <option>Hot Dog, Fries and a Soda</option>
  <option>Burger, Shake and a Smile</option>
  <option>Sugar, Spice and all things nice</option>
</select>

如何在表单选择标签中添加 data-live-search="true"？

我的表单选择:

<%= f.select :food_id, options_for_select(Food.all.map{|c| [c.name, c.id]}, f.object.food_id), {}, {class: "form-control selectpicker"} %>

我尝试过的:

<%= f.select :food_id, options_for_select(Food.all.map{|c| [c.name, c.id]}, f.object.food_id), {}, {class: "form-control selectpicker", data: "live-search"} %>

但它不起作用。
