ruby-on-rails - Rails haml 选择助手默认值

Question

在haml我有这个：

= label_tag :card_month, "Card Expiration"
= select_year nil, {start_year: Date.today.year, end_year: Date.today.year+15}, {name: nil, id: "card_year",}

我想将选择年份的默认值设置为 2020。我该怎么做？

谢谢

我猜

= select_year Date.new(2020), {start_year: Date.today.year, end_year: Date.today.year+15}, {name: nil, id: "card_year"}
