Do you use django's caching framework?

Just got to know about this one: https://docs.djangoproject.com/en/5.2/topics/cache/ (good docs!)

It says, for small to medium sites it isn't as important. Do you use it, e.g. with redis to cache your pages?

Oh and I don't know if it is just me, but whenever I deploy changes of my templates, I've to restart the gunicorn proccess of django in order to "update" the site on live.

Django’s URL philosophy seems to contradict Domain Driven Design

Hey everyone, I’ve been using Django for many years now, but just recently started learning about DDD. There’s one part in Django’s docs that I’m trying to relate (https://docs.djangoproject.com/en/5.2/misc/design-philosophies/#id8):

> URLs in a Django app should not be coupled to the underlying Python code. Tying URLs to Python function names is a Bad And Ugly Thing.

At the heart of DDD is a ubiquitous language, which so far to my understanding, I think, means to prefer using the same language across the business logic, to the URL, to the Python function names, and even perhaps to the form class name, and even template file name. Ideally to prefer that way, at least. Needless to say, I know that that’s not a rule cast in stone, there’ll always be exceptions and considerations.

BUT the way Django’s docs portrays it seems to suggest like that’s not the way to think about it AT ALL.

What do you think?

Deploying on LAN

Hi, it’s my first time deploying a web app and I’d like to know if what I’m gonna do is right.
I have a Django application that I need to deploy on a windows machine and make that useable in the LAN.
the step that I did were:
- set DEBUG = False, ALLOWEDHOSTS=[*] and CSRFTRUSTEDORIGINS=[‘http://<PC IP IN LAN>’]
- installled waiterss and setup serve.py script using address 0.0.0.0 and port 8000
-setup Nginx for reverse proxy this way :
Location / {
Proxypass http://localhost:8000
}
this setup works and I can use application on other device in the same LAN, but I’d like to know if I missed something or I did something unsafe.

Thanks for reading and for the help.

Views on recent acceptance of LLM written paper at ACL main D

Hi folks, just came across this blog
https://www.intology.ai/blog/zochi-acl

It started with ICLR workshop and now ACL main, was just wondering where are we heading. Is this all the effect of noise review process, or indeed the works are worth publishing

PS: Not a NLP guy, so couldn't really comment on the novelty/technical correctness of the work

Edit: Just found a GitHub repo, corresponding to the agent

Tired of tracing code by hand?

I used to grab a pencil and paper every time I had to follow variable changes or loops.

So I built DrawCode – a web-based debugger that animates your code, step by step.
It's like seeing your code come to life, perfect for beginners or visual learners.

Would appreciate any feedback!

Python Object Indexer

I built a package for analytical work in Python that indexes all object attributes and allows lookups / filtering by attribute. It's admittedly a RAM hog, but It's performant at O(1) insert, removal, and lookup. It turned out to be fairly effective and surprisingly simple to use, but missing some nice features and optimizations. (Reflect attribute updates back to core to reindex, search query functionality expansion, memory optimizations, the list goes on and on)

It started out as a minimalist module at work to solve a few problems in one swoop, but I liked the idea so much I started a much more robust version in my personal time. I'd like to build it further and be able to compete with some of the big names out there like pandas and spark, but feels like a waste when they are so established

Would anyone be interested in this package out in the wild? I'm debating publishing it and doing what I can to reduce the memory footprint (possibly move the core to C or Rust), but feel it may be a waste of time and nothing more than a resume builder.

flask-security - Does anyone tried to embed a "change email" or "change password" form only in more general template ?


Rather than having a specific page to permit users to change their email (which is the default behaviour of flask-security), I would like to embed the html form in a more versatile template (user details where user can adjust any of its data).

I did this and it kinda work but... When submiting the email change request, the app systematicaly redirects to the default "change email" flask-security page. I should add that the confirmation email has already been sent at that moment.

I can't block the loading of the default template or force the redirection after submiting the embeded form.

Any clue ?

Have Erasmus+ scholarship and I'm looking for a 2-month internship in any EU country

Hello everyone 👋
I’m a final-year SWE student graduating in early July.

I’ve secured an Erasmus+ scholarship and I'm currently looking for a two-month internship opportunity where I can grow both technically and professionally.

I'm open to any tech role since I’m just starting my career, I’m eager to gain experience in anything I work on. That said, I’d love something backend-related with Django, since I really enjoy working with it. My graduation project is actually a hospital management system built with DRF and Next.js.

Right now, I’m doing a remote internship with a U.S. based company, but I want to make the most of the Erasmus+ program to expand my skills and network.

I just need a company to send me an acceptance letter and erasmus and I will take care of everything else.

I’d really appreciate any support or referrals 🙏

Every time I touch settings.py, I age 3 years.

Why does configuring Django feel like diffusing a bomb with a blindfold on… while it’s also on fire… and your cat is stepping on the keyboard? Meanwhile, Node devs just vibe with dotenv. 😂 Let's unite, scream into the void, and pretend we totally understand ALLOWED_HOSTS.

ayu - a pytest plugin to run your tests interactively

# What My Project Does

ayu is a pytest plugin and tui in one.
It sends utilizes a websocket server to send test events from the pytest hooks directly to the application interface to visualize the test tree/ test outcomes/ coverage and plugins.

It requires your project to be uv-managed and can be run as a standalone tool,
without the need to be installed as a dev dependency.
e.g. with:

uvx ayu

Under the hood ayu is invoking pytest commands and installing itself on the fly, e.g. uv run --with ayu pytest --co is executed to run the test collection.

You can check the source code on github: https://github.com/Zaloog/ayu

# Target Audience
Devs who want a more interactive pytest experience.

# Comparison

Other plugins which offer a tui interface e.g. pytest-tui https://github.com/jeffwright13/pytest-tui exist.
Those are only showing a interface for the results of the test runs though
and do not support for example
- searching/marking specific tests and run only marked tests
- exploring code coverage and other plugins
