[Nguyen Ngoc Lan]

@phatnt You should merge two lines by: redirect_to root_path if current_cart.line_items.empty?

[Nguyen Ngoc Lan]

@phatnt How can you get cart without association belongs_to :cart

[Tan Phat Nguyen]

cart is parameter in situation order not relationship with cart flow: cart has_many line_items order has_many line_items and set cart_id = nil in line_item and set order_id in equal line_item

[Nguyen Ngoc Lan]

@phatnt You should move those errors to a partial called _errors.html.erb in application folder. Then you can render to here by: render 'errors'

[Nguyen Ngoc Lan]

@phatnt You should remove comment

[Nguyen Ngoc Lan]

@phatnt Please remove json.jbuilder
