Another Friday, another Django related post. I guess this blog is becoming a bit monothematic. I promise the next ones will bring the much-needed diversity of contents, but today let’s explore a very useful feature of the Django’s ORM. Ok… Ok… it’s more of a feature of PostgreSQL that Django supports, and it isn’t available […]
This week, I’ll continue on the same theme of my previous “Django Friday Tips” post. Essentially, we will keep addressing small annoyances that can surface while developing your multilingual project. The challenge for this article shows up when a given string from a package that is a dependency of your project is either: As we […]
Here we go again for another post of this blog’s irregular column, entitled Django’s Friday Tips. Today let’s address a silent issue, that any of you that have formerly worked with internationalization (i18n) almost certainly already faced. You add a string that must be translated: You then execute the manage.py makemessages –locale pt command, go […]
This week, I’m back at my tremendously irregular Django tips series, where I share small pieces of code and approaches to common themes that developers face when working on their web applications. The topic of today’s post is how to implement a counter that isn’t vulnerable to race conditions. Counting is everywhere, when handling money, […]

You need to update and upgrade your software, your system components, your apps, your dependencies, etc. This happens to all computer users. On some systems, this is an enjoyable experience, on other systems as painful […]
Last week, an article was published with some interesting numbers about the security of PostgreSQL servers publicly exposed to the internet (You can find it here). But more than the numbers, what really caught my attention was the fact that most clients and libraries used to access and interact with the databases have insecure defaults: […]
A few years ago I built a small application to test Django’s websocket support through django-channels. It basically displayed on a web page in real time all the requests made to a given endpoint (you could generate multiple of them) without storing anything. It was fun and it was very useful to quickly debug stuff […]
Django management commands can be very helpful while developing your application or website, we are very used to runserver, makemigrations, migrate, shell and others. Third party packages often provide extra commands and you can easily add new commands to your own apps. Today lets take a look at some less known and yet very useful […]
