What is "line_items"?

Rails
1

hi guys,
I am looking at #141 PayPal Basics - RailsCasts 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

Gordon

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

line_items is a model/table.

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

def full_price
unit_price * quantity
end
end

Yes, it’s a user defined model.
