4th paragraph (counting the code block as 1 para)

The following sentence has a typo: "The first argument, module: order". It should be "model: order".

code block at the top

The code block shows the line "belongs_to :product" as having changed, but actually it's the line below "belongs_to :cart, optional: true" which has changed, since the "optional: true" hash is new.

default line_item.rb file is :

class LineItem < ApplicationRecord
belongs_to :product
belongs_to :cart

def total_price
product.price * quantity
end
end


change the arrow from this


class LineItem < ApplicationRecord
➤ belongs_to :order, optional: true
➤ belongs_to :product
belongs_to :cart, optional: true

def total_price
product.price * quantity
end
end



to this


class LineItem < ApplicationRecord
➤ belongs_to :order, optional: true
belongs_to :product
➤belongs_to :cart, optional: true

def total_price
product.price * quantity
end
end
