orderlines=customer.orders.orderlines would be great, but that doesn't work
The problem is that customer.orders works, but returns a collection of orders. And a *collection* doesn't have any orderlines.
A good bet would be customer.orders.collect{|o| o.orderlines} which would collect the orderlines from all of the orders and return them.
You'd end up with an array of arrays (this will only make sense in a fixed width font:)
------- order 1 ------- - order 2 - , ------------- order 3 ------------- [ [orderline1, orderline2], [orderline3], [orderline4, orderline5, orderline6] ]
if you only want the orderlines then you can call customer.orders.collect{|o| o.orderlines}.flatten which will collapse the above into one big array.
