First and foremost, I would like to thank the original authors of the Django Book-Adrian Holovaty and Jacob Kaplan-Moss. They provided such a strong foundation that it has really been a delight writing this new edition.

Equal first in the shout out has to be the Django community. Vibrant and collaborative, the Django community is what really stood out to this cynical old businessman many years ago when I first discovered the “new kid on the webframework block”. It’s your support that makes Django so great. Thank you.

Preface

What you need for this book

Required programming knowledge

Readers of this book should understand the basics of procedural and object-oriented programming: control structures (such as if, while, or for), data structures (lists, hashes/dictionaries), variables, classes, and objects. Experience in web development is, as you may expect, very helpful, but it is not required to understand this book. Throughout the book, I try to promote best practices in web development for readers who lack this experience.

Required Python knowledge

At its core, Django is simply a collection of libraries written in the Python programming language. To develop a site using Django, you write Python code that uses these libraries. Learning Django, then, is a matter of learning how to program in Python and understanding how the Django libraries work. If you have experience programming in Python, you should have no trouble diving in. By and large, the Django code doesn't perform a lot of magic (that is, programming trickery whose implementation is difficult to explain or understand). For you, learning Django will be a matter of learning Django's conventions and APIs.

If you don't have experience programming in Python, you're in for a treat. It's easy to learn and a joy to use! Although this book doesn't include a full Python tutorial, it highlights Python features and functionality where appropriate, particularly when code doesn't immediately make sense. Still, I recommend you read the official Python tutorial (for more information visit http://docs.python.org/tut/). I also recommend Mark Pilgrim's free book Dive Into Python, available online at http://www.diveintopython.net/ and published in print by Apress.

Required Django version

This book covers Django 1.8 LTS. This is the long term support version of Django, with full support until at least April 2018.

If you have an early version of Django, it is recommended that you upgrade to the latest version of Django 1.8 LTS. At the time of printing (July 2016), the most current production version of Django 1.8 LTS is 1.8.13.

If you have installed a later version of Django, please note that while Django's developers maintain backwards compatibility as much as possible, some backwards incompatible changes do get introduced occasionally. The changes in each release are always covered in the release notes, which you can find at https://docs.djangoproject.com/en/dev/releases/.
