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.
The book is splitted in 10 different chapters, and although you will see a "getting started" one, the approach is to go deep in common issues that anybody serious on django related development will meet.
From path settings, common / best project structure, to advanced topics like model mixins (common case like modification date and time for record), Hierarchical structures (django mptt power is discussed here) and CMS integration: practical solutions with plenty of code and, most interesting, the "How it works" section for every recipe that tells a lot of Django inner workings.
I give the book high ratings and really recommend it.
The e-book has a very attractive price at Packt, you can follow this link to find it.
