You probably should not use this book for Django 1.5. It says: " While the book mentions Django version 1.4 in places, the vast majority of the book is for Django version 1.0" And " we ask that, at this time, djangobook.com not be used for educational purposes. "
Actually, you should start with Django 1.6 or even 1.7 (1.5 is outdated!) and use official Django tutorial (https://docs.djangoproject.com/en/dev/intro/tutorial01/) instead of this book.
