我觉得我在这里重复太多了，希望 DRY它，但我不知道该怎么做。

我有一个 Prize 模型，其中一个属性是 prize_type这是一个选择(您可以在名为 PRIZE_TYPE 的 CONSTANT 中选择 4 个值之一)。我有一个 table_for对于每种类型的奖品。

例如，如果有一天我在数组 .map 中添加第五个或第六个值，我想使用某种映射(PRIZE_TYPE ？) , 我希望我的面板自动添加它们而无需复制/粘贴另一个 table_for在下面:

show do 

    def custom_number_to_currency(u)
      number_to_currency u,
        separator: ".",
        delimiter: ",",
        precision: 0,
        raise: true  
    end    



 panel "Details of Prizes" do

  table_for deal.prizes.where(:prize_type => PRIZE_TYPES[0]) do |t|
    h3 "The deal has #{deal.prizes.where(:prize_type => PRIZE_TYPES[0]).count} #{PRIZE_TYPES[0]}s
    initially set in the campaign for a total value of #{custom_number_to_currency (deal.prizes.where(:prize_type => PRIZE_TYPES[0]).sum(:prize_unit_certified_market_value)) }", class: 'title-within-table'
    if deal.prizes.where(:prize_type => PRIZE_TYPES[0]).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 }
      t.column("Remaining quantity"){ |prize| if prize.prize_remaining_stock_quantity == 0
                                                status_tag('no prizes left (all won)', :class => 'green')
                                              else
                                                prize.prize_remaining_stock_quantity
                                              end } 

  end

  table_for deal.prizes.where(:prize_type => PRIZE_TYPES[1]) do |t|
    h3 "The deal has #{deal.prizes.where(:prize_type => PRIZE_TYPES[1]).count} #{PRIZE_TYPES[1]}s
    initially set in the campaign for a total value of #{custom_number_to_currency (deal.prizes.where(:prize_type => PRIZE_TYPES[1]).sum(:prize_unit_certified_market_value)) }", class: 'title-within-table'
    if deal.prizes.where(:prize_type => PRIZE_TYPES[1]).count > 0 # if there is at least one record of 'in-modal 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 }

                                              end }
