Overview of this book

<p>Django is a high-level Python web framework that was developed by a fast-moving online-news operation to meet the stringent twin challenges of newsroom deadlines and the needs of web developers. It provides an excellent basis to build e-commerce websites because it can be deployed fast and it responds quickly to changes due to its ability to handle content problems. Django with its proven strengths is all you need to build powerful e-commerce applications with a competitive edge. <br /><br />This book explores how the Django web framework and its related technologies can power the next leap forward for e-commerce and business on the Web. It shows you how to build real-world applications using this rapid and powerful development tool.<br /><br />The book will enable you to build a high quality e-commerce site quickly and start making money. It starts with the ambitious task of using Django to build a functional e-commerce store in less than 30 minutes, and then proceeds to enhance this design through the rest of the book. The book covers the basics of an e-commerce platform like product catalogs, shopping carts, and payment processing. By the end of the book, you will be able to enhance the application by adding a fully-functional search engine, generating PDF-based reports, adding interactivity to the user-interface, selling digital goods with micropayments, and managing deployment and maintenance tasks.</p>

A Google Checkout class


The Checkout API is capable of several checkout patterns. In Chapter 2, Setting Up Shop in 30 Minutes, we implemented the simplest pattern involving a single "Buy It Now" button. In Chapter 3 we implemented a custom shopping-cart solution. In the previous section we built a generic approach to implement checkout functionality for any service. We will now implement our Google Checkout shopping cart solution using this generic framework. Later in this chapter we will also implement another checkout service, Amazon's Flexible Payment System, on top of our generic framework.

To build our Google Checkout class, we inherit all of the functionality from our generic checkout view and add some additional data and methods. We will store our Google API and merchant key as class attributes as well as the shopping cart XML template name. Our XML template will be treated like the checkout HTML template, which will give us the flexibility to use different XML shopping cart templates...
