Django: find ghost tables without associated models
Heavy refactoring of models can leave a Django project with “ghost tables”, which were created for a model that was removed without any trace in the migration history. Thankfully, by using some Django internals, you can find such tables. Use the database introspection methods table_names() to list all tables and django_table_names() to list tables associated with models. By casting these to sets, you can subtract the latter from the former to find tables not associated with a model: In [1]: from django.db import connection In [2]: table_names = set(connection.introspection.table_names()) In [3]: django_table_names = set(connection.introspection.django_table_names()) In [4]: table_names - django_table_names - {"django_migrations"} Out[4]: {'sweetshop_humbug', 'sweetshop_jellybean', 'sweetshop_marshmallow'} Note the django_migrations table needs excluding. This is Django’s internal table for tracking migrations, which has no associated (permanent) model. From here, you’ll want to make a judgement call on what to do with the tables. Perhaps should have models and others can be removed. If a ghost table has no useful data or migration references, consider dropping it directly with SQL, rather than adding a migration. This can be done with dbshell. For example, using PostgreSQL: $ ./manage.py dbshell psql (...) Type "help" for help. candy=# DROP TABLE sweetshop_humbug; DROP TABLE Fin May your … -
Weeknotes (2024 week 47)
Weeknotes (2024 week 47) I missed a single co-writing session and of course that lead to four weeks of no posts at all to the blog. Oh well. Debugging I want to share a few debugging stories from the last weeks. Pillow 11 and Django’s get_image_dimensions The goal of django-imagefield was to deeply verify that Django and Pillow are able to work with uploaded files; some files can be loaded, their dimensions can be inspected, but problems happen later when Pillow actually tries resizing or filtering files. Because of this django-imagefield does more work when images are added to the system instead of working around it later. (Django doesn’t do this on purpose because doing all this work up-front could be considered a DoS factor.) In the last weeks I suddenly got recurring errors from saved files again, something which shouldn’t happen, but obviously did. Django wants to read image dimensions when accessing or saving image files (by the way, always use height_field and width_field, otherwise Django will open and inspect image files even when you’re only loading Django models from the database…!) and it uses a smart and wonderful1 hack to do this: It reads a few hundred bytes … -
Introducing DjangoVer
Version numbering is hard, and there are lots of popular schemes out there for how to do it. Today I want to talk about a system I’ve settled on for my own Django-related packages, and which I’m calling “DjangoVer”, because it ties the version number of a Django-related package to the latest Django version that package supports. But one quick note to start with: this is not really “introducing” the idea of DjangoVer, because I know I’ve used the name a few times already in other places. I’m also not the person who invented this, and I don’t know for certain who did — I’ve seen several packages which appear to follow some form of DjangoVer and took inspiration from them in defining my own take on it. Django’s version scheme: an overview The basic idea of DjangoVer is that the version number of a Django-related package should tell you which version of Django you can use it with. Which probably doesn’t help much if you don’t know how Django releases are numbered, so let’s start there. In brief: Django issues a “feature release” — one which introduces new features — roughly once every eight months. The current feature release series of Django is 5.1. … -

Boost Your Django DX updated again
I have just released the second update to Boost Your Django DX, my book of developer experience (DX) recommendations for Django projects. This update contains a new chapter, changes some recommended tools, and upgrades to Python 3.13 and Django 5.1. Overall, the book is 45 pages longer, now totalling 326! The most significant new addition is a chapter on debuggers: Python’s built-in one, pdb, and IPython’s enhanced version, ipdb. The chapter introduces pdb with realistic examples, covers all the essential commands, and includes many tips, like using the .pdbrc configuration file. Another major change is swapping the recommended CSS and JavaScript tools from ESLint and Prettier to Biome. Biome is a super-fast formatter and linter for CSS, JavaScript, JSON, TypeScript, and more. The new section introduces it and provides integration advice for Django projects. Thank you to everyone who has supported the book so far. Just the other day, it reached fifty five-star reviews. I am very grateful for all the feedback from the community and aim to keep improving the book. This update is free for all who previously purchased the book. To help readers catch up, the introduction chapter has a changelog with links to the updated sections, … -

Heroku To DigitalOcean - Building SaaS #206
In this episode, I began a migration of my JourneyInbox app from Heroku to DigitalOcean. The first step to this move, since I’m going to use Kamal, is to put the app into a Docker image. We got the whole app into the Docker image, then cleaned up local development and the CI system after making changes that broke those configurations. -

Three Django wishes
<p>’Tis the season when people are posting their “Django wishlists”, for specific technical or organizational or community initiatives they’d like to see undertaken. Here are a few&nbsp;examples:</p> <ul> <li><a href="https://gist.github.com/sarahboyce/68ffaaeae24d2501cf27a914f77fb97c">Sarah&nbsp;Boyce</a></li> <li><a href="https://www.better-simple.com">Tim&nbsp;Schilling</a></li> <li><a href="https://softwarecrafts.co.uk/100-words/day-203">Andy&nbsp;Miller</a></li> <li><a href="https://emma.has-a.blog/articles/django-wishlist-explained.html">Emma&nbsp;Delescolle</a></li> </ul> <p>So, in the spirit of the season, here is my own list, which I’ve narrowed down to three wishes (in the tradition of many stories about wishes), consisting of one organizational item and two technical&nbsp;ones.</p> <h3>Pass the&nbsp;torch</h3> <p>This one requires a bit of background, so please bear with&nbsp;me.</p> <p><a href="https://www.djangoproject.com/foundation/">The Django Software Foundation</a> — usually just abbreviated “<span class="caps">DSF</span>” — is the nonprofit organization which officially “owns” Django.
