Question

In the method below, I do ol.price * ol.committed. price is a decimal (40.00)

  def self.find_for_order(order)
    if order
      select("ol.*, p.name as name, (ol.price * ol.committed) as sku_total, p.price as price, p.style_number AS product_style_number, p.name").
      from("order_lines ol").
      joins("LEFT JOIN skus s ON s.sku_number = ol.style_number").
      joins("LEFT JOIN products p ON p.id = s.product_id").
      where("ol.order_id = #{order}").
      group("ol.id, p.price, product_style_number, name, ol.style_number")
    end
  end

In my view I have this:

number_to_currency(@order_lines.map(&:sku_total).sum)

This is the result:

$500,400.00

If I run inspect on it I get this:

["500", "400"]

So it thinks they are strings, and just slapping them together instead of adding them. Any ideas how to fix this?

Answer 1

cast the values to numbers.

number_to_currency(@order_lines.map{|ol| ol.sku_total.to_f }.sum)
