如何降序显示日期 select 中的年份?

how to display years in date select descendingly?

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,你是怎么做到的?:

2015
2014
2013
....
1900

谢谢。

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-
