如何在 rails 中添加默认 dd/mm/yyyy 标签而不是空选择器？

Question

这是我的 rails 表单中日期选择器的代码-

  <div class="field columns large-3">
    <%= form.label :planned_start_date, :class=>"required" %>
    <%= form.date_select :planned_start_date, start_year: @project_start_year, end_year: @project_end_year, :include_blank => true, order: [:day, :month, :year], class: 'select-date' %>
  </div>

  <div class="field columns large-3">
    <%= form.label :planned_end_date, :class=>"required" %>
    <%= form.date_select :planned_end_date, start_year: @project_start_year, end_year: @project_end_year, :include_blank => true, order: [:day, :month, :year], class: 'select-date' %>
  </div>
</div>

我想默认添加 dd mm yyyy 而不是空选择器。我该如何改变它？

如 ruby 文档中所述 date_select

= form.date_select :planned_end_date, start_year: @project_start_year, end_year: @project_end_year, :include_blank => true, order: [:day, :month, :year], prompt: { day: 'dd', month: 'mm', year: 'yyyy' }, class: 'select-date'
