Noob Question 31,265,232
if I’m searching on an object, say order, that has many “order_lines”
and I want to display order lines by Quantity ( an attribute of the
order_lines ) descending
how could I do that without having to do a find() with :order, but
something like;
Order.order_lines.each do |ol|
how can I determine the field and the way I order the results?
Thanks in advance,
Randal the Newbie
Nevermind, I’m just a little slow. I was puttin in the ORDER class, how
to order the order_lines, and didn’t realise I could do
has_many :order_lines, :order => “quantity DESC”
problem solved, and now archieved for future noobs

class Order < ActiveRecord::Base
has_many :order_lines, :order => “order_lines.quantity”
end
