Strange Array behaviour
I''m having a strange thing when using the Enumerable extensions for

class Invoice < ActiveRecord::Base
has_many :invoice_lines
def total
invoice_lines.sum(&:total)

class InvoiceLine < ActiveRecord::Base
belongs_to :invoice
def total
amount * price

Invoice and invoice_lines
Hello People,
I have a possibly very lame question.
I am fairly new to RoR, and I want to make sure I do it "right".
I have a model called Invoice, and one called InvoiceLines. Usual story:
the table "invoice" has a 1:n relationship with "invoice_lines", which
includes invoice_id.
Now... the application will have a "new order" button, which will allow
the user to enter all of the order details, etc. Then, the user will
want to add invoice_lines, which are obviously associated with the
order.
The easiest solution I can think...
