Django: iterate through all registered URL patterns
I’ve found it useful, on occasion, to iterate through all registered URL patterns in a Django project. Sometimes this has been for checking URL layouts or auditing which views are registered. In this post, we’ll look at a pattern for doing that, along with an example use case. Get all URL patterns with a recursive generator The below snippet contains a generator function that traverses Django’s URLResolver structure, which is the parsed representation of your URLconf. It extracts all URLPattern objects, which represent individual URL patterns from path() or re_path() calls, and returns them along with their containing namespace. It handles nested URL resolvers from include() calls by calling itself recursively. from typing import Iterator, Optional from django.urls import URLPattern, URLResolver, get_resolver def all_url_patterns( url_patterns: Optional[list] = None, namespace: str = "" ) -> Iterator[tuple[URLPattern, str]]: """ Yield tuples of (URLPattern, namespace) for all URLPattern objects in the given Django URLconf, or the default one if none is provided. """ if url_patterns is None: url_patterns = get_resolver().url_patterns for pattern in url_patterns: if isinstance(pattern, URLPattern): yield pattern, namespace elif isinstance(pattern, URLResolver): if pattern.namespace: if namespace: namespace = f"{namespace}:{pattern.namespace}" else: namespace = pattern.namespace yield from all_url_patterns(pattern.url_patterns, namespace) else: raise TypeError(f"Unexpected pattern type: … -

Why Django's DATETIME_FORMAT ignores you
When you start a new Django project, you get a handful of default settings for localization and timezones: settings.py USE_I18N = True LANGUAGE_CODE = "en-us" USE_TZ = True TIME_ZONE = "UTC" I’ve written before about the default timezone being a silly choice for sites with a global user base, both on the backend and the frontend. But today, I want to talk about internationalization (I18N) and language settings. For my sites, LANGUAGE_CODE = "en-us" is perfectly fine; all my admin users speak English, and we prefer American spelling over the British variant. But there are some weird things going on in Django that I want to address. The USE_I18N puzzle Here’s the first weird thing. The default settings have USE_I18N = True, which enables Django’s internationalization features. The default LANGUAGES setting also includes a massive list of every language under the sun. You’d think this means the Django Admin would automatically switch languages. If I set my browser’s preferred language to Dutch, shouldn’t the Admin follow suit? Nope. It remains stubbornly English. It turns out you need to add this to your middleware for the translation to actually happen: settings.py MIDDLEWARE = [ # ... "django.middleware.locale.LocaleMiddleware", ] Only after adding … -
Django at 20: a personal journey through 16 years
Django turned 20 a few days ago, which is a remarkable milestone for any software project. I’ve been along for most of that ride, starting my Django journey in September 2009. That’s almost 16 years ago! It’s been fascinating to watch both Django and my use of it evolve over time. From server-rendered pages to APIs and back When I started with Django in 2009, it was a different world. Everything was server-rendered, with a bit of jQuery sprinkled in. I wrote my very first Django article in November 2009 about dynamically adding fields to models. This was quickly followed by articles on what I didn’t like about Python and Django and how to use Jinja2 templates in Django, which solved some of my pain points. In 2012, my focus shifted dramatically. I went from full-time web developer to full-time iOS developer. Django didn’t disappear from my life though, it just changed roles. Instead of building full websites, I was creating REST APIs to power mobile apps, which is when I discovered Django REST Framework. Fast forward to 2023, and I’ve come full circle, returning to full-time web development. These days, I mostly use SvelteKit on the frontend with Django … -
How to Get Foreign Keys Horribly Wrong
Constraints keep the integrity of your system and prevent you from shooting yourself in the foot. Foreign keys are a special type of constraint because, unlike unique, check, and primary keys, they span more than one relation. This makes foreign keys harder to enforce and harder to get right. In this article, I demonstrate common pitfalls, potential optimizations, and implicit behavior related to foreign keys. Table of Contents Naive Implementation Enhanced Implementation Replacing unique_together Identifying Duplicate Indexes Identifying Blocking Migrations Safely Migrating Foreign Key Reversible Migration Operations Concurrent Index Operations Indexes on Foreign Keys Partial Foreign Key Indexes Using Built-in Concurrent Index Operations Order Migration Operations Locking Across Relations Permissive No Key Locks The Final Model Takeaways The Mandatory AI Angle Watch 📺 This article is inspired by a talk I gave at DjangoCon EU.

Happy Birthday to Django!
Over the weekend Django celebrated being 20 years since the first public commit. This is an incredible achievement for a community led project. Django is behind some tiny projects to those that scale globally and personally my career wouldn't be where is it without Django. Most of my career existed with only a vague awareness of the community, but since getting involved on Discord and beyond has been great for my soul and enjoy those that share the passion of seeing Django succeed. So as we celebrate 20 year's would be to get involved if you use Django, go to an event, donate to the DSF or join us in the community (online and in person). If you work for a company that use's Django lobby them to donate as well! I am excited for the next decade of slow but sure progress and the community being healthier than ever before. -

What if Django was written in a new language..
So this is a bit of a follow on from Day 277 and taking the premise of the idea presented with it and pushing it further. What if we, as a community decided to (re-)write Django in another language? It's not as wild as you might think, Lily Foote is currently tackling an implementation of the Django template language in Rust and someone else suggested that URL resolving might benefit from a similar treatment. However that is not the goal of this push forward, but it is again Django as design pattern or set of API's. If we wanted to allow someone to migrate Django (or even part of it) to a new language, some comphrensive API documentation outside the codebase and inside the codebase would be a good start. And as I write this I realise that we do have this, it's the amazing test suite that helps to make Django stable (that's all 17898 tests and counting), but even then a test suite is never the whole story. Today was more of a pondering thought and not a complete one at that, but more of a thought experiment and a consideration (to myself more than anyone) of what … -
Python Leiden meetup: Handling crash reports with Bugsink - Klaas van Schelven
(One of my summaries of the fourth Python meetup in Leiden, NL). Bugsink is a tool/website for collecting error messages from (for instance) your websites. You get an email or other notification and you can visit the error page. You'll see the exact error and a traceback and the environment variables and the library versions. But... isn't that just like sentry? Yes. Mostly. But... why bugsink? It is self-hostable. Originally, 20 years ago, sentry was also self-hostable, but it isn't anymore. There's a bit of workflow, too. You can mark issues as "fixed in the next release". Bugsink will then ignore new occurrences of the error until it notices you made a release. It is not just in the same market as sentry, it is even sentry-compatible. If you already have sentry set up, moving to bugsink only means changing the SENTRY_DSN setting. The API is the same. Self-hosting? You can run a docker. He showed that pip install bugsink also works. It is just a plain regular django site with migrate and runserver. A single instance can easily handle 1.5 million errors per day. Some generic tricks (whether sentry or bugsink): Just use your error tracker in development, too! … -
Python Leiden meetup: Deploying python apps with django-simple-deploy - Michiel Beijen
(One of my summaries of the fourth Python meetup in Leiden, NL). Michiel discovered django simple deploy via the django podcast. Deploying? Previously, heroku was often used as an example in books, but they ditched their free tier and are pretty expensive now. So most examples nowadays just show you how to run django locally. Deploying is harder. There are several hosting parties that provide relatively easy django hosting like heroku. https://fly.io, https://platform.sh and https://heroku.com . "Easy" is relative, as he ran into some problems with platform.sh and he didn't have an ssh connection to fix it. And yesterday they nuked his account so he couldn't re-try it for today's demo. Since recently there is also a generic "vps" plugin: just running on some random virtual server with ssh access that you can rent virtually anywhere. https://github.com/django-simple-deploy/dsd-vps . "Random" should be debian-like, btw. He demoed it on a digitalocean VM (="droplet"). With some environment variables he got it working within 15 minutes and some manual fixes. The longest wait was the "apt-get upgrade" call. The VPS version of simple deploy has its drawbacks. It needs a root password, for instance, and at the moment it doesn't accept ssh key authentication. … -
Django-Tailwind Just Got Better with a Unified Dev Command and daisyUI
I created Django-Tailwind back in 2019, at a time when most Djangonauts hadn’t even heard of Tailwind CSS.

Handling static and media files in your Django app running on Coolify
In a previous article, I detailed my journey of hosting Django sites with Coolify, covering everything from the Dockerfile and database setup to environment variables and server configuration. It was a comprehensive guide to get a Django application up and running. However, I deliberately left out one tricky topic: handling static and media files. This aspect of deployment can be complex and certainly deserves its own article. If your application only serves static files - the CSS, JavaScript, and images that are part of your core application - the solution is thankfully really simple: use WhiteNoise. It is, by far, the easiest way to serve static files directly from your Django application in production without needing a separate web server just for them. However, if you’re also dealing with user-uploaded media files then you have to deal with two challenges: where to store the files and how to serve them. Let’s assume you have a standard configuration in your settings.py: STATIC_ROOT = BASE_DIR / "static_root" STATIC_URL = "/static/" MEDIA_ROOT = BASE_DIR / "media_root" MEDIA_URL = "/media/" The primary problem is that media files uploaded by users will be saved inside the Docker container. Because Coolify creates a fresh container from … -
Using Google Consent Mode v2 on a Django Website
A decade ago, adding website analytics was simple: you’d just paste a JavaScript snippet from Google Analytics, and that was it. But things changed. As people became more concerned about their privacy, countries introduced strict privacy laws—like GDPR in the European Union, PIPEDA in Canada, and APPI in Japan. These laws gave users more control over their data and placed new responsibilities on us developers. One of those responsibilities is showing Cookie Consent banners and respecting users’ choices before loading any tracking scripts. Today, if you want to add Google Analytics to your website, it’s not just about copying a script. You need to understand Google Tag Manager (GTM)—a tool that lets you manage what scripts run on your site and when, using a web-based dashboard. When you add Google Analytics as a Google tag through GTM, it doesn’t automatically start collecting data. It waits for a signal called Consent Mode, which tells Google whether the user has accepted or denied tracking. This signal must be sent from your website to GTM as an event. That’s where your Cookie Consent widget comes in. For Django websites, I created Django GDPR Cookie Consent, which lets you manage user consent and send … -
Weeknotes (2025 week 27)
Weeknotes (2025 week 27) I have again missed a few weeks, so the releases section will be longer than usual since it covers six weeks. django-prose-editor I have totally restructured the documentation to make it clearer. The configuration chapter is shorter and more focussed, and the custom extensions chapter actually shows all required parts now. The most visible change is probably the refactored menu system. Extensions now have an addMenuItems method where they can add their own buttons to the menu bar. I wanted to do this for a long time but have only just this week found a way to achieve this which I actually like. I’ve reported a bug to Tiptap where a .can() chain always succeeded even though the actual operation could fail (#6306). Finally, I have also switched from esbuild to rslib; I’m a heavy user of rspack anyway and am more at home with its configuration. django-content-editor The 7.4 release mostly contains minor changes, one new feature is the content_editor.admin.RefinedModelAdmin class. It includes tweaks to Django’s standard behavior such as supporting a Ctrl-S shortcut for the “Save and continue editing” functionality and an additional warning when people want to delete inlines and instead delete the … -

Rate Limiting for Django Websites
Sometimes, certain pages of a Django website might receive unwanted traffic from crawlers or malicious bots. These traffic spikes consume server resources and can make the website unusable for legitimate users. In this article, I will explore Nginx’s rate-limiting capabilities to prevent such performance issues. What is rate limiting, and why use it? A typical Django website is deployed using a Gunicorn (or Uvicorn for ASGI) application server, with an Nginx web server in front of it. When a request comes to Nginx, it goes through various checks, gets filtered by domain, protocol, and path, and is finally passed to Gunicorn. Gunicorn then runs Django, which parses the URL and returns a response from the appropriate view. Nginx rate limiting allows you to limit how often certain pages (based on URL paths) or all Django endpoints can be accessed. It prevents quick reloading or scripted attacks that flood your site with requests. This is especially useful for pages with forms, faceted list views, REST APIs, or GraphQL endpoints. A typical rate-limiting configuration in Nginx defines a zone with a specific memory size (in megabytes), a rate (requests per second or per minute), and one or more locations that apply that … -
Hosting your Django sites with Coolify
I currently run four Django apps in production, with staging and production environments for each. For years, I’ve managed this on a single server with a stack that has served me well, but has grown increasingly complex: A Hetzner VPS running Debian 12 Nginx as a reverse proxy Gunicorn processes managed by systemd More systemd services for background task runners A custom deploy service that listens for GitHub webhooks to pull and restart the right app A custom backup script that archives configs and databases and ships them offsite to rsync.net. I’ve written about this setup in detail, both in “Setting up a Debian 11 server for SvelteKit and Django” and more recently in “Automatically deploy your site when you push the main branch”. While not rocket science, it’s a non-trivial setup. Each new app requires a checklist of configuration steps, and it’s easy to miss one. Worse, my deploy script involves a brief moment of downtime as Gunicorn restarts. It’s only a second or two, but it’s not ideal. I’m more of a developer than an operations person, and building a zero-downtime, rolling deploy script myself feels like a step too far. On the other end of the spectrum, … -
I am back
Well it's been more than a few weeks since I last managed to get some words out the door or even have the headspace for writing. This was mostly down to the new startup picking up steam and client work taking up time, but also a wedding, holiday's and other priorities coming in for me to deal with! All that to say, I'm back for a little while at least, summer is fast approaching which means holiday's again. I'll keep today short as I don't have a particular topic fully developed in mind, but few things I have in my head recently are: AI has finally clicked in my head especially with Agentic stuff coming through. This is what I expected a few years back when ChatGPT was released. The true skill these days seems to be ticket writing (although AI developing PRD documents is something I need to try out). Also using git worktrees to allow multiple agents working on my projects at the same time and creating my own custom AI agents.. I have been enjoying, with the help of AI, the python attrs and cattrs library to validate data going to and from Stripe. I'm excited by … -

Django: hide the development server warning
From Django 5.2 (April 2025), the runserver management command outputs a warning: $ ./manage.py runserver ... Starting development server at http://127.0.0.1:8000/ Quit the server with CONTROL-C. WARNING: This is a development server. Do not use it in a production setting. Use a production WSGI or ASGI server instead. For more information on production servers see: https://docs.djangoproject.com/en/5.2/howto/deployment/ The warning uses bold, yellow text for emphasis. Here’s the relevant release note: A new warning is displayed when running runserver, indicating that it is unsuitable for production. This warning can be suppressed by setting the DJANGO_RUNSERVER_HIDE_WARNING environment variable to "true". I think the warning is somewhat useful for new users, who do sometimes skip the deployment checklist that states that runserver is not designed for production use. That said, the warning is rather annoying for the majority of users who have correctly set up a production server. I also fear it will lead to warning fatigue, normalizing that runserver outputs lots of warning text, making it easier to skip over other, more pressing messages that may be logged. If you’ve set up your production environment to use a secure server, like gunicorn, then you probably want to hide this warning. As the release … -
Production-ready cache-busting for Django and Tailwind CSS
I’m a big fan of the django-tailwind-cli package. It makes integrating Tailwind CSS into a Django project incredibly simple. By managing the Tailwind watcher process for you, it streamlines development, especially when paired with django-browser-reload for live updates. It’s a fantastic developer experience. However, when I first deployed a project using this setup, I ran into a classic problem: caching. You see, django-tailwind-cli creates a single tailwind.css file that you load in your base template. In production, browsers and CDNs will aggressively cache this file to improve performance. This is normally a good thing! But when you deploy an update, like adding a new Tailwind class to a template, your users might not see the changes. Their browser will continue to serve the old, cached tailwind.css file, leading to broken or outdated styling. Luckily, Django has a built-in cache-busting mechanism in the form of ManifestStaticFilesStorage. But, there’s one important caveat: you can’t use this class directly. The Tailwind build process relies on a source file (typically css/source.css) that contains this line: @import "tailwindcss"; When collectstatic runs, ManifestStaticFilesStorage tries to be helpful and process this file, too. It attempts to find and hash source.css, and it also attempts to hash the … -

Django: Introducing inline-snapshot-django
I recently released a new package called inline-snapshot-django. It’s a tool for snapshot testing SQL queries in Django projects, described shortly. Snapshot testing and inline-snapshot inline-snapshot-django builds on top of the excellent inline-snapshot, a nifty snapshot testing library. Snapshot testing is a type of testing that compares a result against a previously captured “snapshot” value. It can enable you to write tests quickly and assert on many details that you'd otherwise miss. Snapshot testing is quite popular in other languages, such as JavaScript, but it has been underused in Python. This may be due to a lack of good tools to help automate snapshot management. inline-snapshot provides nice workflows tied into pytest, so I hope it will popularize the technique among Python and Django developers. The inline-snapshot developer, Frank Hoffmann, is working intensely on it, and he provides some extra tools and features for his GitHub sponsors. inline-snapshot-django I created inline-snapshot-django to provide an advanced yet easier-to-use alternative to Django’s assertNumQueries(). While assertNumQueries() is handy, it is a rather blunt tool that leaves you in the dark when debugging failures. For example, say you encountered this test: from django.test import TestCase class IndexTests(TestCase): def test_success(self): with self.assertNumQueries(1): response = self.client.get("/") … -
