what is "line_items"?

[ct9a]

hi guys,
I am looking at http://railscasts.com/episodes/141-paypal-basics and
I am trying to figure out what's line_items?

Is it a reserved keyword representing a row of a multi row form or is
it just a variable that's called line_items (and is not a reserved
keyword)?

If it is a reserved keyword/function in rails, can someone please
point me to some documentation?

thanks

line_items is a model/table.

class LineItem < ActiveRecord::Base
belongs_to :cart
belongs_to :product

def full_price
unit_price * quantity
end
end

ah right. So it is a user defined model. Am I right?

Yes, it's a user defined model.
