If you have developed a few Django applications, you'll probably know that for most applications, a lot of the code and configurations that you do when starting out is the same. You set up the database in the same way, maybe changing the Database (DB) name and user/pass pairs, you set up your media, static URL, and root paths, and then you add user authentication using the built-in auth contrib application and the provided views, only creating minimal templates that are good enough to get the job done in the start.
Walking you through the basic setup at the start of every chapter would be very boring—both for you to read and for me to write. Instead, I've provided what I call Code Packs. These are zip files that contain the Django application already set up so that we can jump straight to the interesting parts of the code instead of having to go through the tedious setup process again and again.
Don't worry, I won't skip any new Django features that we haven't looked at...
