I highly recommend Two Scoops of Django and have recommended to every engineer at my company. The one caveat would be that the newest edition is for Django 1.8, so it'd be good to check against the docs periodically if anything looks off. Off the top of my head, the main thing I'd keep an eye out for would be changes to Class-Based Views like permissions mixins, although if I remember correctly, most of those changes were just moving things in django-braces to Django core.
