Date 使用bootstrap 3的简单表单包装每个日期选择的方法

是否有一种方法可以将每个选择包装在简单的表单输入中作为日期？ 现在我使用这个，但是我希望为每个选择都有一个额外的包装器

config.wrappers :date_wrapper, class: 'form-group' do |b|
  b.use :html5
  b.use :placeholder
  b.use :label, class: 'col-md-4 control-label'
  b.wrapper class: 'col-md-8 form-group date-selects' do |inputs|
    inputs.use :input, class: 'form-control'
    inputs.use :hint,  wrap_with: { tag: 'span', class: 'help-block' }
    inputs.use :error, wrap_with: { tag: 'span', class: 'help-inline' }
  end
end

= f.input :date, as: :date, wrapper: :date_wrapper

产生以下结果：

<div class="form-group">
  <div class="col-md-6 date required">
    <label class="date required col-md-4 control-label" for="date_3i">
      Date
      <abbr title="required">*</abbr>
    </label>
    <div class="col-md-8 form-group date-selects">
      <select aria-required="true" class="date required form-control" id="date_3i" name="date[date(3i)]" required="required">...</select>
      <select aria-required="true" class="date required form-control" id="date_2i"  name="date[date(2i)]" required="required">...</select>
      <select aria-required="true" class="date required form-control" id="date_1i"name="date[date(1i)]" required="required">...</select>
    </div>
  </div>
</div>
