I’ve been working through the book, and I’ve gotten up to the point where I need to test adding items to my cart. However, when I click on any of the size buttons, it takes me to an error page where it says “no route found for POST /cart/add (Sneakers23Web.Router)”.
I checked the router.ex file under sneakers_23_web and there’s no entry for the /cart/add path, and there isn’t a CartController.ex file at all either so I’m not sure where to go from here.
