For the month of June I decided to post daily-ish social media threads (to both Mastodon and Twitter) on interesting Django-related ideas using the hashtag #DjangoJune.

During the month of June (#DjangoJune) I shared #Django-related musings nearly every daily.
Here's a categorized summary of Django June. ππ¦
I'm surprised at how fruitful some of these threads were! π

What should you do if you need to run code "in the background" with #Django?
I recommend using a task queue. Specifically, I'd use Celery.

When one of the pages in my #Django admin interface feels a bit sluggish, what's the first thing I do?
Install (or enable) django-debug-toolbar and check the SQL panel.
Usually admin interface speed issues are related to N+1 issues.

How many models should you stick in your #Django app's models module?
When should you make a new app instead of adding more models to an existing app?
There isn't a straightforward answer to this question, but here are some things to consider...
#DjangoJune
Nearly all my #Django projects end up using django-simple-history at some point.
I pretty much always have at least one model where I wish I had access to all past model states either for customer support, debugging, or marketing/stats.

Pretty much all my projects also use django-relatives, which is my own library that includes helpers for linking between model relations in the admin interface.
You can find more admin-related packages here: https://t.co/pDrAFkUcfe
#DjangoJune
There are SO many useful third-party libraries for enhancing #Django's admin interface.
I pretty much always use django-admin-sortable for drag and drop sorting and django-admin-rangefilter for filtering by date ranges on my change lists.

Django signals: use them or avoid them?
If you'd like an event to trigger on each model save, #Django signals are the typical built-in solution, but they have their downsides...
I used to embrace signals, but now I use django-lifecycle. π§΅
#DjangoJune
A controversial #Django topic:
class-based views (CBVs) or function-based views (FBVs)? π€
I started with function-based views, but after a few years of using Django I pretty much moved fully to class-based views. Both have pros & cons (and vocal advocates).

How should you name #Django apps?
My guidelines:
β’ Try sticking to a single word
β’ Pluralizing the app's main model is great (users, exercises)
β’ A singular noun representing the topic is okay too (billing, blog)
β’ Use all lowercase!
β’ Avoid underscores
#DjangoJune
Here's an odd & interesting #Django fact I rarely use: you can use F objects on model attributes and they'll trigger when save() is called.
product.upvotes = F("upvotes") + 1
product.βsave()
Just keep in mind that every save triggers the F expression.

There's a TON to learn about #Django's ORM!
Here are some talks I recommend on this topic:

Note the dates as some are new and some are old #DjangoJune
Database administrators worried about scaling need to know their SQL.
Django devs worried about scaling need to know their ORM.
Yes, you CAN resort to raw SQL when you need to, but you so rarely do!
Let's talk about the power of #Django's ORM.
#DjangoJune
If your Django admin site is accessible from any IP, I recommend linking to it in your site navigation bar, but only reveal that link to admin users.
I use the Django admin site a TON but I rarely type in the URL. Instead just click "Admin" after logging in.
#DjangoJune
With option 3, code like this:
>>> exercise.was_solved
Turns into this:
>>> exercise.stats.was_solved
That's only slightly more verbose!
We're still able to easily access the methods & data we need from a model object, but our model's code can be much shorter!
