Welcome to the second edition of The Definitive Guide to Django, informally known as The Django Book! This book aims to teach you how to use the Django Web framework to develop Web sites efficiently.

When Jacob Kaplan-Moss and I wrote the first edition of this book, Django was still in a pre-1.0 stage. Once Django version 1.0 was released, with its several backward-incompatible changes, the first edition inevitably became outdated and people began demanding an update. I'm happy to report this edition covers Django 1.1 and should serve you well for some time.

My thanks go to the many contributors who posted comments, corrections, and rants to http://djangobook.com/, the accompanying Web site for this book, where I posted chapter drafts as I wrote them. You guys are great.
