Django: fix a view using a debugger with breakpoint()
This post is an adapted extract from my book Boost Your Django DX, available now with a 50% discount for Black Friday 2024. Python’s breakpoint() function opens its debugger, pdb, which pauses the program and allows you to inspect and modify things. Let’s look at an example of using it within a Django view, from a sample project included in Boost Your Django DX. Here’s what the project looks like: This page, “Party Central”, lists animals with their pizza preferences and whether they’re hungry. Underneath the table are two filter buttons, “Hungry” and “Satiated”, which allow you to select only animals with those hunger levels. Unfortunately, the filter buttons are broken. Click “Hungry” to load http://localhost:8000/?hungry=1 and we see the same list of animals: The hungry URL parameter is there, and the button is highlighted, but the data isn’t filtered. Let’s use pdb to figure out why. We can run pdb with the breakpoint() function, a Python built-in that opens the configured debugger (which is pdb by default). Let’s add it to the view function, before it renders the template. Here’s how the views.py file looks: from django.shortcuts import render from example.models import Animal def index(request): animals = Animal.objects.order_by("name") hungry … -
Creating AI-based Summaries in a Django Website
Summarizing lengthy text can be tedious, especially on platforms like PyBazaar, where concise summaries improve user experience. In this post, I'll share how I used Simplemind and Gemini to automate this process in my Django-based project. Background Info Recently, I launched PyBazaar.com, a website for Python developers to show their skills, find job offers, and post and find development resources. Its purpose is to have a central place where Python developers can market their services, products, or projects. PyBazaar shows lengthy descriptions of career opportunities and resources in the detail views and short summaries in the list views. Summaries help users quickly grasp the content of resources and career opportunities without opening each detailed view, enhancing the overall browsing experience on PyBazaar. To make the editing smoother, I introduced automatic summarization based on AI. Choosing Simplemind for Communication with LLMs Kenneth Reitz, the author of the famous package requests, recently published his newest creation—Simplemind—which improves the developer experience with the APIs of large language models (LLMs). I thought it would be a good opportunity to try integrating his package into PyBazaar. While I chose Google Gemini for its free tier, Simplemind's support for providers like OpenAI or Claude means developers … -

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, … -
