total_cost = 0
total_items = 0
rows =
db(query).select(db.item.base_price,db.item.price,db.sale.total_items)
for r in rows:
total_price += r.item.price * r.sale.total_items
total_cost += r.item.base_price * r.sale.total_items
total_items += r.sale.total_items

return dict(total_price = str(total_price) , total_profit =
str(profit) , total_items = str(total_items))
