django-carton 1.2.0

Usage Example

View:

from django.http import HttpResponse

from carton.cart import Cart
from products.models import Product

def add(request):
    cart = Cart(request.session)
    product = Product.objects.get(id=request.GET.get('product_id'))
    cart.add(product, price=product.price)
    return HttpResponse("Added")

def show(request):
    return render(request, 'shopping/show-cart.html')

We are assuming here that your products are defined in an application called products.

Template:

{% load carton_tags %}
{% get_cart as cart %}

{% for item in cart.items %}
    {{ item.product.name }}
    {{ item.quantity }}
    {{ item.total_price }}
{% endfor %}

You can also use this convinent shortcut:
{% for product in cart.products %}
    {{ product.name }}
{% endfor %}
