A bit of googling and you will find many excellent resources - filter on 'last year' in the search results. One recommended book is 'two scoops of Django'. You should get familiar with the request response cycle (Language agnostic) and that will make things a lot clearer as you build up your skills.

Two scoops is an okay book I suppose, but it's definitely not what the grandparent post is asking for -- it goes over things too quickly.

I actually recommend youtube video tutorials! Like, some will show you how to make a basic photo hosting site... a blog site, etc. Follow those once or twice, and take it from there. Best of luck!

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.

newboston on youtube. I needed a crash course on django -- after the first couple of videos I knew what I needed. But, I got hooked by his fast pace and finished the set over 2 days. A+

Subquery expressions looks like it would be just easier to write SQL, instead of going through the Django ORM. This is where SQL starts to show its expressive strength over ORMs.

Absolutely. The amount of "magic" Django does slowly became a real detractor for me. The way I define queries by using a custom language in the form of keyword arguments makes me wonder why I don't just learn SQL instead? I would much rather do something like: models.Foo.objects.filter(sql=my_sql_query_str) Instead of something like: models.Foo.objects.filter(name='bar', parent__siblings__count__lt=3) And no special…

You have to learn SQL to use the Django ORM anyways; it's required knowledge in order to be able to wield the higher level abstraction effectively. However, the way you write a lot of these things in SQL is substantially more verbose and harder to compose.

I recommend TreeHouse's Django series. I tried other methods (books, blog posts, none really helped me). Not free either, but it really helped. There's a free trial so you can learn Django quickly in 7 days (I did) but I am keeping my membership for now to learn other stuff... (although kinda pricey for me). The series is not up-to-date either, but the basics remain unchanged. You may find one or two syntax / API differences, but that's it.

I also grew up with Django... since 0.9 but didn't really focus on web development using Django, so for me I had to pick it up again from scratch and quick. Two Scoops is a reference book at best IMO. Use it if you are really comfortable with all the basics of Django and you have done at least 6-12 months of Django regularly.

> The Django 1.11.x series is the last to support Python 2. The next major release, Django 2.0, will only support Python 3.5+.

Really the most important part of this release, out of all.

This is the time where enterprise companies using Python and Django really need to switch to Python 3. In fact, anyone using Ubuntu 16.04 should already find themselves going "ugh" because they needed Python 2. More reasons to push forward.

Release notes with the new features in 1.11: https://docs.djangoproject.com/en/dev/releases/1.11/ Highlights: - better support for creating indexes on your Models with class-based indexes - widget rendering in forms now uses the templating system instead of python - Explicit subquery expression support via Subquery and Exists expressions.

widget rendering in forms now uses the templating system instead of python I haven't looked at how it's implemented yet, but that sounds like a real godsend.

I have looked at it, and it is a godsend.
