ruby-on-rails – 如何在Rails中添加数据属性表单select tag？

我发现这个 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>

如何在我的表单select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"} %>

我试过的

<%= f.select :food_id,{class: "form-control selectpicker",data: "live-search"} %>

但它不工作

解决方法

尝试：

{class: "form-control selectpicker","data-live-search" => "true" }
