Capturing an Order

An order is a set of line items, along with details of the purchase transaction. Our cart already contains line_items, so all we need to do is add an order_id column to the line_items table and create an orders table based on the initial guess at the application data diagram.

First, we create the order model and update the line_items table:

depot> bin/rails generate scaffold Order name address:text email \
         pay_type:integer

depot> bin/rails generate migration add_order_to_line_item order:references
