Disclaimer - I received a free copy of the ebook.
I was a bit skeptical about this book, as any book with "cookbook" in the title. As far as I know, experience is the only way to really acquire software engineering competence.
With this review, I apologize. The only (small) negative point is that is targeting Django 1.6, but this may be an issue only with the migrations part, where Django 1.7 incorporated the Django South project.
