例如下面的 query

statistics {
    orderSettlementPm
    orderSettlementShop
    todayPaidAmount
    todayPaidOrderCount
  }
}

目前 Resolvers 是这样的，这样会导致不管请求什么字段，都会计算一遍数据？ 问：Resolvers 可不可以获取查询的字段列表？

class Resolvers::SysStatisticsData < Resolvers::Base
  def resolve
    data = {
      paid_order_count: ShopOrderStatistic.sum(:paid_order_count),
      paid_amount: ShopOrderStatistic.sum(:paid_amount),

      today_paid_amount: ShopOrderStatistic.today_paid_amount,
      today_paid_order_count: ShopOrderStatistic.today_paid_order_count,

      yesterday_paid_order_count: ShopOrderStatistic.yesterday_paid_order_count,
      yesterday_paid_amount: ShopOrderStatistic.yesterday_paid_amount,

      today_refund_count: Refund.today_data.success_status.count,
      yesterday_refund_count: Refund.yesterday_data.success_status.count,

      refund_amount: Refund.refund_amount_sum,
      withdraw_amount: WithdrawLog.withdraw_amount_sum,
      wait_withdraw_amount: WithdrawLog.processing_paid.sum(:amount),

      view_count: 100,
      yesterday_view_count: 100,

      wait_ship_order_count: Order.paid_status.count
    }
  end
end
