Mercurial Mirror For Django 4.2 Branch
Slightly late, but here’s the 4.2 mirror. As usual, read-only, and aimed at production (aka “using django on servers “), not development (aka “commit”). -
Backend Development 101 with Django REST Framework
If you’re familiar with Python, you’ve most certainly heard of Django, but may not know what it is used for and why people like it so much. We will first run through a ‘backend development 101’ crash-course, then talk about Django’s take on backend development and what Django REST Framework provides on top of it. Finally we will add a feature to an example Django app and do some live coding. -

An introduction to Django Simple History
Wouldn’t it be useful if we could document changes in our life and revisit them later at will? It would allow us to better analyze situations, remember what we were thinking, or help us remember how we got to our current state. Although no such tool currently exists for changes in life, one such tool does exist in Django. It is called django-simple-history. Django-simple-history stores Django model state on every create, update, or delete database operation; it can even revert back to old versions of a model, record which user changed a model, interact with multiple databases, and more. Rather than making code changes, django-simple-history gives us the ability to view and perform many of the changes via the admin interface. Let’s imagine we are creating a simple Polling application and our models.py file looks like this: from django.db import models class Poll(models.Model): question = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') published = models.BooleanField(default="False") def __str__(self): return self.question How do we get django-simple-history to work on our application? Install django-simple-history: pip install django-simple-history In the settings.py file, Add simple_history to INSTALLED_APPS: INSTALLED_APPS = [ # ... 'simple_history', ] The historical models can track which user made each change. To automatically populate … -
Single-pages without the single-page with django2-tables, django-filter, and htmx
Introduction I've been meaning to use htmx since it came out, but I've never had time, nor the occasion. Now the opportunity finally came to refactor an old Django which uses the Datatable jQuery plugin. I wanted to try something fresh, and htmx seemed the way to go, paired with a couple of great libraries: django2-tables and django-filter. Let's see how they play well together! Please, take this post as personal notes, don't expect a step-by-step tutorial :-) The theory htmx is a JavaScript library for building dynamic user interfaces which lets you enrich HTML elements with "magic" attributes. With htmx, any actionable HTML element can make XHR requests. The magic comes from two htmx attributes: hx-get hx-target hx-get basically says: when the user clicks this element, make a GET request to the given URL, then swap the content of hx-target with the partial response. (POST requests are also supported). The basic principle behind htmx used in the context of server-side web frameworks is the following: if the frontend request comes from htmx, we return a partial HTML fragment instead of the whole document. In Django, this translates to: if the request comes from htmx, we return a partial template … -
Running your Django project with __main__.py
I don’t like Django’s manage.py. My gripes against it are: The plethora of files that clutter the root directory of our repos annoys me. manage.py is just one more in a long line of those. In my opinion, there are more “Pythonic” ways to execute code. In a previous post, I talked about how you can move the code into your project and use packaging tools to create a manage.py on your PATH during installation. In this post, we’ll look at another approach using __main__.py What is __main__.py (and __main__)? The Python docs do a good job of explaining this topic, so I’ll give you the tl;dr here. __main__.py provides a command line interface to a Python package. It can be executed with python -m mypackage. Here are some common ones you may have seen in the wild: python -m pip python -m venv python -m json.tool You may also be surprised to learn that python -m django can be used in place of the django-admin command. 🤯 The “magic” here is that each one of those packages has a __main__.py which defines what it should do when run from the command line. In each of these, you’ll see a … -
Using pyproject.toml in your (Django) project
Back in 2018, I wrote about using setup.py in your Django/Python project. Five years later, setup.py is being phased out in favor of pyproject.toml. I'm a big fan of this change. With setup.py you could really go off the rails making everything dynamic or even executing malicious code during the installation process. In contrast, pyproject.toml moves the ecosystem towards a configuration file that can be parsed without executing arbitrary code. You can read more about the rationale behind pyproject.toml in PEP-517, PEP-518, PEP-621, and PEP-660. Creating your pyproject.toml file If you're using poetry, pdm, or any of the other newer Python build systems, you're already using pyproject.toml. How about folks that are using plain old pip or pip-tools? You can still take advantage of this new file format and ditch setup.py and/or setup.cfg as well. Most third-party tooling supports configuration via the tool section defined in PEP-518. To start, define the build system for your project. To avoid introducing new tools, we're going to use good ol' setuptools: [build-system] requires = ["setuptools>=61.0"] build-backend = "setuptools.build_meta" Next, define your project and its dependencies: [project] name = "myproject" version = "1.0" dependencies = [ "dj-database-url", "django==3.2.*", "gunicorn", "psycopg2", "whitenoise", ] [project.optional-dependencies] dev … -
Django Dev Made Easy: How to Run Multiple Processes Simultaneously

Weeknotes (2023 week 6)
Weeknotes (2023 week 6) Rust I made some progress learning Rust. I don’t have to look up each character and function and am slowly getting a feel for the language, unwrapping and the borrow checker, so that’s nice. I don’t have a use for it for now, but we’ll see. feincms3-data and data cycles I added support for loading data with cyclic dependencies to feincms3-data. This is useful e.g. when having Django models where you have a ForeignKey("self") and you want to use feincms3-data to insert a new copy of some object and its dependencies. Editing trees in the Django administration interface I’m back to one of my favorite (not) activities which is making tree-shaped data editable in the Django administration panel. FeinCMS and later django-mptt augments the changelist with some drag drop behavior. There’s no undo functionality though so making errors is potentially really bad. feincms3 uses a separate page for moving nodes around. Now I’m working on a Preact-based project which also doesn’t use drag drop but which also allows inserting nodes, not just moving nodes around. I doubt I can make it reusable enough to make it useful for feincms3 but we’ll see. -

Weeknotes (2023 week 5)
Weeknotes (2023 week 5) A long time has passed since I tried writing week notes. Oh well, here we go again. No committment here, just hope. Podcasts Really got into listening to podcasts in the last few weeks. That’s new for me, I never enjoyed listening to people talk when I could also listen to music. So, that’s interesting. Podcasts I like a lot: The Ezra Klein Show, Django Chat and some others where I haven’t yet listened enough to list them here. Advent of Code I knew that Advent of Code existed quite long already but I never dug into it. I participated in the 2022 Advent of Code and enjoyed it a lot. I have long been unsecure regarding my programming skills since I do not have a formal CS background so it felt really good to be able to solve many problems with only a little help. Definitely not all of them though. It definitely was fun and I’m still working through other years a bit. Python is the most fun, JavaScript is sometimes nice. Rust gives me a hard time (or I’m giving myself a hard time) but the upside is that solving even easy puzzles … -

Introducing: YAMS (Yet Another Media Server)!
Hello internet 😎 I’m here with a big announcement: I have created a bash script that installs my entire media server, fast and easy 🎉 TL;DR I’ve created YAMS. A full media server that allows you to download and categorize your shows/movies. Go to YAMS’s website here: http://yams.media or check it on Gitlab here: https://gitlab.com/rogs/yams. A little history When I first set up my media server, it took me ~2 weeks to install, configure and understand how it’s supposed to work: Linking Sonarr, Radarr, Jackett together, choosing a good BitTorrent downloader, understanding all the moving pieces, choosing Emby, etc. My plan with YAMS is to make it easier for noobs (and lazy people like me) to set up their media servers super easily. I have been working on YAMS for ~2 weeks. The docker-compose file has existed for almost 2 years but without any configuration instructions. Basically, you had to do everything manually, and if you didn’t have any experience with docker, docker-compose, or any of the services included, it was very cumbersome to configure and understand how everything worked together. So basically, I’m encapsulating my experience for anyone that wants to use it. If you don’t like it, at … -

Configuring Sphinx Auto-Doc with projects having Django dependencies
How to make it so projects with Django as a dependency benefit from Sphinx's auto-documentation features. The Problem I want to be able to document open source packages with Sphinx (ex. xocto) and have Sphinx automatically document the Django helpers. This isn't quite the same as documenting a Django project, so I wasn't sure if the otherwise awesome sphinxcontrib-django would be the right tool. Fortunately, there's a solution that doesn't require any additional packages. The Solution Configuration First, in the Sphinx docs folder, create a file called django_settings.py and add the following: """ Minimal file so Sphinx can work with Django for autodocumenting. Location: /docs/django_settings.py """ # INSTALLED_APPS with these apps is necessary for Sphinx to build # without warnings & errors # Depending on your package, the list of apps may be different INSTALLED_APPS = [ "django.contrib.auth", "django.contrib.contenttypes", ] Next, at the top of Sphinx's conf.py, add the following: # docs/conf.py import os import sys import django # Note: You may need to change the path to match # your project's structure sys.path.insert(0, os.path.abspath("..")) # For discovery of Python modules sys.path.insert(0, os.path.abspath(".")) # For finding the django_settings.py file # This tells Django where to find the settings file os.environ["DJANGO_SETTINGS_MODULE"] … -
