I am currently following the depot application from the book Web Agile
Development with Rails (3rd Edition) but after creating the controller
for the Store and the Cart model, I am always getting a nil product, no
matter how many products I add to the database.
I am very new with RoR (this only the page 110 of the book) and thus I
am not very sure about what I could do to mitigate the problem.
Thanks a lot in advance!
