Есть кусочек кода, который отвечает за отображение количества товаров в корзине
data = cartData(request)
cartItems = data['cartItems']
order = data['order']
items = data['items']
Его как-то нужно поместить в класс DetailView, чтобы на отдельных страницах товара тоже работала корзина class Product_det(DetailView). Я попытался, но ничего не получилось. Может лучше это вынести в отдельный тег?
