Following tutorial w/ rails 4.0.beta and ruby 2.0. In the chapter 12 checkout section when I click checkout I get the below error instead of figure 22 on page 166. Have others experienced this? If so send a solution. Thanks.
NoMethodError in OrdersController#new
undefined method `line_items’ for nil:NilClass
error points to this line in the orders controller

To correct this, add the following lines at the top of the file:
