Question about using DISTINCT in ActiveRecord find method.
Hi,
Am relatively new to the RoR world. My question is quite simple.
I have a query like such:
shipmentNumbers = Order.find_by_sql(["select distinct s.id from orders
o, line_items li, shipment_lines sl, shipments s where o.number=? and
o.id = li.order_id and li.id = sl.line_item_id and sl.shipment_id =
s.id", number])
The above query works fine. I wanted to do the same query using

Saving one-many associations (elegant solution please)
What is the most elegant way to save new one-many associations?
order = Order.new(:name => "My Order")
order.line_items << LineItem.new(:product_id => 1, :quantity => 2)
order.line_items << LineItem.new(:product_id => 2, :quantity => 5)
order.save
The above - which is by far the most elegant way of putting it - doesn''t

Cannot see what I have done wrong.
In the Agile Rails tutorial I am revisiting building a cart. I have
followed the steps given in the book to create the class ''Cart''
thus:
class Cart
attr_reader :items
attr_reader :total_price
def add_product(product)
@items << LineItem.for_product(product)
@total_price += product.price
end
def initialize
@items = []
@total_price = 0.0

Hey all,
I''m trying to find a simple way to reference all of the objects that

Thanks!
