In my experience, the purpose of this book is extremely unusual in programming books. Most of them are either an introduction to the topic, or a reference book like a 'cookbook' or what basically amounts to a printed version of the online documentation. Those books get the job done for people with a project (or an employment position) in mind. They learn what they need to do to use the technology, then they get to work. We should all know by now that reading a book doesn't actually teach you anything -- you have to go out and actually apply that knowledge to really "know" the technology.But what if you want to learn to use Django, but don't have a project in mind? How cool would it be if one of the core Django developers created a couple of fully-functional applications, step-by-step, and let you follow along? That's exactly what James Bennett has done here. You can literally be brand-new to Django and finish this book having written multiple Django applications, learning all the major functionality of Django along the way, and even implementing best-practices for creating reusable applications.If you've been working with Django for any length of time, a lot of this book will feel like review, because it does explain templates, views, URLs, models, and the MTV concept. However, there's a lot in here for you as well. Here are some of the cool things in this book that you don't find in any of the standard documentation sources:\* How to (easily) integrate a rich-text editor into the Django admin interface\* Use third-party modules such as pygment, the Delicious API, and Akismet spam-blocking\* In-depth examples of creating custom template tags\* Complete examples of integrating django.contrib applications (such as comments and feeds)\* Notes on version control, distributing apps, building and deploying appsAll that and more, plus this is probably the definitive guide to writing your Django applications to be reusable. In conclusion, if you're brand-new to Django and want a yellow-brick road to walk down, here it is. If you're an experienced Django programmer, you don't need this book, but I practically guarantee you'd learn a couple of things you didn't know. If you are new to Django, however, I highly recommend that once you finish this book you read The Definitive Guide to Django: Web Development Done Right, Second Edition cover-to-cover once you finish this book. It will fill in all the gaps and you'll really be able to do pretty much anything in Django.

You'll work through the development of each project, implementing and running the applications while learning new features along the way. Web frameworks are playing a major role in the creation of today's most compelling web applications, because they automate many of the tedious tasks, allowing developers to instead focus on providing users with creative and powerful features. Python developers have been particularly fortunate in this area, having been able to take advantage of Django, a very popular open-source web framework whose stated goal is to "make it easier to build better web applications more quickly with less code." Practical Django Projects introduces this popular framework by way of a series of real–world projects. Readers follow along with the development of each project, implementing and running each application while learning new features along the way. This edition is updated for Django 1.1 and includes an all-new chapter covering practical development tools and techniques you'll be able to apply to your own development workflow. "The aim of this book is to guide you toward becoming a more effective developer, regardless of whether you're new to web development or an old hand. This book explains the technical details of developing applications with Django, but more importantly, it shows you how Django can help you write clean, flexible code with an eye toward reusability." The book is organized around three useful projects: a content management system, a blog, and a social code-sharing site. The process of building each one will expand your knowledge of Django and of best practices for high-quality application development. As you progress through these projects, you'll come to understand each of Django's major components, from database interaction and server-side processing all the way up to form handling for user interaction and HTML templating for presentation. Along the way, you'll also learn how Django's application architecture can lead to powerful and flexible applications that you'll be able to use and reuse whenever you need them. You'll pick up key principles of application design that you'll be able to apply to improving your own code. In this book, you’ll see how Django can help you achieve both of these goals—rapid application development and flexible, reusable code—through both the tools it provides to you directly and the development practices that it makes possible. I’ll guide you through the development of several example applications and show you how the various components and applications bundled with Django can help you write less code at each stage of the development process. You’ll also see first-hand a number of best practices for reusable code and learn how you can apply them in your own applications. Plus, you’ll learn how to integrate existing third-party libraries into Django-powered applications to minimize the amount of code you’ll need to write from scratch.
