It is a great resource, but it is getting out of date. They even have a disclaimer on that page [1] now:
While the book mentions Django version 1.4 in places,
the vast majority of the book is for Django version 1.0,
which was released over four years ago.
Therefore this resource is extremely out of date and,
until the book is finished being updated, we ask that,
at this time, djangobook.com not be used for educational purposes.
That matters most to a beginner. If you're following along at home with Django 1.6, and the code doesn't work like it says, then you're stuck.
