How to get a count of line_items
..._items as an example.
An order has_many line_items
A line_item belongs to order
In my OrdersController I have
def summary
@orders = Orders.find(:all)
render :xml => @orders.to_xml()
end
What I want to achieve is to include a count of line_items per order,
and to include it as say total_line_items in the output.
I don''t know how to a.) get the count per order, b.) how to include in
the output.
Thanks
Andrew
