Question

Hi
I wonder if there’s a way to do this without involving advance SQL code?

Model 1.
Product
:has_many prices

Model 2.
Retailer
:has_many prices
:has_one profile

Model 3.
Price – price:integer
:belongs_to :retailers
:belongs_to :products

Model 4.
Profile – Shippingcost:integer
:belongs_to :retailers

I want to be able to sort by(:price+:shippingCost), I know how to do this with SQL, with left joins and creating a “(bla + bla2) AS totalPrice and sort it by totalPrice, but is there a simpler way to do this?

Answer 1

So,ething like that. But it is too deep nested

Product.includes(:prices => {:retailer => :profile}).select("products.*, (prices.price + profiles.shippingcost) AS sum).order(:sum)
