Ruby on rails Spree产品价格范围筛选器不工作

在实习期间，我需要处理一个现有的RubyonRails项目。 这项工程是疯狂建造的。我之前的开发者调整了价格过滤器，使范围变为该分类群产品的最大值。 这里的代码是“lib/spree/core/product_filter.rb”

Spree:：Product.add_search_scope:price_range_any do|*选项|
opts_arr，max_prod，min_prod=[]，nil，nil
选择。每个都做|选择|
tmp_arr=opt.split（“+”）
选择
Spree::Product.add_search_scope :price_range_any do |*opts|
        opts_arr, max_prod, min_prod = [], nil, nil
        opts.each do |opt|
          tmp_arr = opt.split("+")
          opts_arr << tmp_arr[0]
          max_prod = tmp_arr[1]
          min_prod = tmp_arr[2]
        end
        conds = opts_arr.map {|o| Spree::Core::ProductFilters.price_filter(max_prod.to_i, min_prod.to_i)[:conds][o]}.reject { |c| c.nil? }
        scope = conds.shift
        conds.each do |new_scope|
          scope = scope.or(new_scope)
        end
        Spree::Product.joins(master: :default_price).where(scope)
      end

      def ProductFilters.format_price(amount)
        Spree::Money.new(amount)
      end

      def ProductFilters.price_filter(max_price = nil, min_price = nil)
        v = Spree::Price.arel_table
        if max_price < 200
          if max_price < 100
            highest_price = max_price - max_price.modulo(10)
          else
            highest_price = max_price - max_price.modulo(25)
          end
          interval = (highest_price)/5
          second = interval + interval
          third = second + interval

          conds = [ [ "#{format_price(0)} - #{format_price(interval)}"     , v[:amount].in(0..interval)],
                    [ "#{format_price(interval)} - #{format_price(second)}"        , v[:amount].in(interval..second)],
                    [ "#{format_price(second)} - #{format_price(third)}"        , v[:amount].in(second..third)],
                    [ "#{format_price(third)} - #{format_price(highest_price)}"        , v[:amount].in(third..highest_price)],
                    [ Spree.t(:or_over_price, price: format_price(highest_price)) , v[:amount].gteq(highest_price)]]
          {
            name:   Spree.t(:price_range),
            scope:  :price_range_any,
            conds:  Hash[*conds.flatten],
            labels: conds.map { |k,v| [k, k] }
          }
        else
          conds = [ [ "#{format_price(0)} - #{format_price(50)}"     , v[:amount].in(0..50)],
                    [ "#{format_price(50)} - #{format_price(100)}"        , v[:amount].in(50..100)],
                    [ "#{format_price(100)} - #{format_price(150)}"        , v[:amount].in(100..150)],
                    [ "#{format_price(150)} - #{format_price(200)}"        , v[:amount].in(150..200)],
                    [ Spree.t(:or_over_price, price: format_price(200)) , v[:amount].gteq(200)]]
          {
            name:   Spree.t(:price_range),
            scope:  :price_range_any,
            conds:  Hash[*conds.flatten],
            labels: conds.map { |k,v| [k, k] }
          }
        end
      end
