我有这样的RoR视图（关于haml）：

-if @articles.blank?
  %h3
    Увы, нет артикулов в данной категории

-else
  - @constr_num.each do |cc|
    = cc.ARL_SEARCH_NUMBER

我认为我必须看到普通表格，但我首先得到=@non_original.each do |no|

[#<PriceList id: 77845, distributor_id: 1, brand: "TECH-AS", article_nr: "110064Q", price: 3.0, quantity: ">8", waittime: 1, description: "110064Q (TO1341D) OX143D 1100696 AUDI/VW TDI", created_at: "2012-10-11 21:21:56", updated_at: "2012-10-11 21:21:56">, #<PriceList id: 7253, distributor_id: 1, brand: "CARGO", article_nr: "B140036", price: 0.0, quantity: "0", waittime: 1, description: "140036A 3471553 Del 12.08x14.08x14.00", created_at: "2012-10-11 09:36:26", updated_at: "2012-10-11 09:36:26">]

但后来我在表格中看到了这个数据......这很神奇）我怎样才能在表格中看到这些数据？

查看截图： screenshot

我的控制器也是这样的：

def get_parts_via_category
    *****(secret))))
    @articles = Kaminari.paginate_array(@pre_articles).page(params[:page]).per(20)

    @asdasd = ArtLookup.get_construction_number(@pre_articles.map(&:ART_ID))
    @constr_num = @asdasd.uniq{|x| x.ARL_SEARCH_NUMBER}
    logger.warn("mE gusta !!!!!!")
    non_original = []
    @pre_articles.each do |a|
      logger.warn("SDFSDFS fsdf sdf sdfSDF SDF SD !!!!!!!!!!! dgfdfg d*fd*g fd-gd f")
      a.logger.warn(a.supplier.SUP_BRAND.gsub(/[^0-9A-Za-z]/, ''))
      norig = get_non_tecdoc(a.ART_ARTICLE_NR.to_s.gsub(/[^0-9A-Za-z]/, ''), 1, a.supplier.SUP_BRAND)
      if norig.present?
        non_original << norig
      end      
    end

    oem_art = []
    @constr_num.each do |o|
      as_oem = get_from_as_oem(o.ARL_SEARCH_NUMBER)
      if as_oem.present?
        oem_art << as_oem
      end
    end    
    @non_original = non_original.uniq
    @oem_art = oem_art.to_a.uniq


    @eur_cur = Currency.find_by_currency_name("EUR")
      @discont = 0
    if user_signed_in?
      @discont = 0.01
      user = User.find(current_user.id)
      @total = 0
      for order in user.orders do
        @total += order.totalcost
        if @total >=0 && @total <= 1000000
          @discont = 0.02
        end
        if @total >=1000000 && @total < 7000000
          @discont = 0.1
        end
        if @total >=7000000 && @total < 10000000
          @discont = 0.15
        end
        if @total >=10000000
          @discont = 0.2
        end
      end
    end
  end

你的专栏：

=@non_original.each do |no|

必须以-符号开头：

-@non_original.each do |no|

这样你就可以隐藏each方法的结果，如果你传递一个块（do ... end或{ ... }），它会返回数组本身：

[1,2,3].each{} # => [1, 2, 3]

Rails视图正在查看太多数据
