Ruby：如何根据可变数量（Active Admin，rails 3.2，ruby）在Active Admin面板中对单词进行复数/单数化]]

Question

我是Ruby on Rails的新手，我无法根据单词的数量来更改单词的结尾。

在下面的代码附近，您会看到我写的

h3 "The deal has #{deal.prizes.where(:prize_type => u).count} #{u}
这里的“ u”采用名为PRIZE_TYPE的数组中的值之一。我该怎么做

• 如果count = 1，则显示“该交易有1个头奖奖金”

• 如果count = 4，则显示“该交易有4个头奖奖励S

注意：计数不能为0或<0

这是我的代码：

panel "Details of Prizes" do

      PRIZE_TYPES.each do |u|

        table_for deal.prizes.where(:prize_type => u) do |t|
          h3 "The deal has #{deal.prizes.where(:prize_type => u).count} #{u}s
          initially set in the campaign for a total value of #{custom_number_to_currency (deal.category_prizes_total_initial_value(u)) }", class: 'title-within-table'
          if deal.prizes.where(:prize_type => u).count > 0 # if there is at least one record of 'jackpot prize'
            t.column("Prize")             { |prize| link_to( image_tag( prize.prize_image_url, class: 'main_img_in_admin_interface' ), admin_prize_path(prize), target: :blank ) }
            t.column("Name")              { |prize| link_to prize.prize_name, admin_prize_path(prize), target: :blank }
            t.column("Category")          { |prize| prize.prize_category }
            t.column("Initial quantity")  { |prize| prize.prize_initial_stock_quantity }

      end # end of Prize.each...

    end # end of panel "details of prizes"
和PRIZE_TYPE常量：

PRIZE_TYPES = ["Jackpot prize","Consolation prize", "awesome prize"]
    

我是Ruby on Rails的新手，我无法根据单词的数量来更改单词的结尾。在下面的代码顶部附近，您会看到我写了h3“该交易具有＃{deal.prizes ....
