如何在rails中添加默认的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>

我想添加dd-mm-yyyy，而不是默认的空选择器。我该怎么改？

如在日期选择的ruby文档中所述

= 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'
