In this chapter, you created a basic shop application. You created a product catalog and built a shopping cart using sessions. You implemented a custom context processor to make the cart available to your templates and created a form for placing orders. You also learned how to launch asynchronous tasks with Celery.
In the next chapter, you will learn how to integrate a payment gateway into your shop, add custom actions to the administration site, export data in CSV format, and generate PDF files dynamically.
