Subject: Agile web Development with Rails section 9.3

Hello
I am reading Agile Web Development with rails (third addition).
And I need some help with it.
I have reached chapter 9.3

when I press on the add to cart button I get an error message.
a real ugly one.

eventually, I downloaded the PDF version and copied the content of the
files but it did not help.

I have looked but could not find the problem.
Please give me a hand.
Thanks
Angel
