[Solved] Rails: Remove Curly Braces in Array [closed]

@temp = SalesOrder.where("status > ?", 0).ids
items = SalesOrderItem.where(sales_order_id: @temp).where.not(product_id: nil)
total = items.to_a.group_by(&:product_id).each_with_object({}) do |(product_id, quantity), total|
  total[Product.find(product_id.to_i).name] = quantity.map(&:quantity).map(&:to_f).sum
end
@top_five = total.sort_by { |k, v| v }.reverse!

Check this. It should work. If any errors, ping me, I will update it

PS: your code is not optimized at all. All of this could be done with single SQL query, but the logic is pretty hard to write this query without debugging
