I'll chime in with also highly recommending the Two Scoops book! It was nice to see their design philosophy. I worked with several older releases of Django and found their thoughts on CBV helpful in deciding when/when not to use them. Also, it was nice to see their thoughts on layout. I stepped away from Django development for awhile and a lot has changed from 1.6 to 1.10! I just wish that they had decided to also offer an electronic version! Any idea if they are planning an electronic release this time?
