# В соответствии с соглашениями название должно быть BasketsController
# насколько понимаю, мы находимся в контексте Rails приложение, значит контроллер должен наследоваться от ApplicationController
class BasketController
# на мой взгляд add_item — это более удачное название метода
def add_to_basket
# Правильно будет искать по id товара
# при этом поиск товара лучше вынести в отдельный метод
# def item
# @item ||= Item.find params[:id]
