如何在日期中显示年份选择下降？

Question

您如何按降序显示年份？目前，我有这个：

<%= f.input :year_started, as: :date, label: "Date started", start_year: Date.today.year - 100, end_year: Date.today.year, discard_day: true, order: [:month, :year], include_blank: true, default: nil, :input_html => { :class => 'profile-date' } %>

下拉年份显示如下：

1900
1901
1902
....
2015

我想要相反的，你怎么做？：

2015
2014
2013
....
1900

感谢。

Answer 1

我认为这就像交换start_year和end_year一样简单。

尝试：

<%= f.input :year_started, as: :date, label: "Date started", start_year: Date.today.year, end_year: Date.today.year - 100, discard_day: true, order: [:month, :year], include_blank: true, default: nil, :input_html => { :class => 'profile-date' } %>

它实际上在API文档中：http://apidock.com/rails/ActionView/Helpers/DateHelper/date_select#190-Get-year-to-show-in-descending-order-Today-to-192-for-example-
