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>

ReportLab: Generating PDF reports from Python


The Python community offers dozens of libraries designed to generate graphics, reports, PDF files, images, and charts. It can be somewhat overwhelming choosing which tool is appropriate for the job. In this section, we will experiment with the ReportLab toolkit, which is a Python module that allows us to create PDF files. ReportLab can be integrated with Django to generate dynamic PDFs on-the-fly for the data stored in our Django models.

ReportLab is an open source project available at http://www.reportlab.org. It is a very mature tool and includes binaries for several platforms as well as source code. It also contains extension code written in C, so it's relatively fast. It is possible for ReportLab to insert PNG and GIF image files into PDF output, but in order to do so we must have the Python Imaging Library (PIL) installed. We will not require this functionality in this book, but if you need it for a future project, see the PIL documentation...
