Do multiple requests create multiple instances of a middleware object?
For example, let's say you have some middleware that does something with process_view(), to run some code before a view is rendered. If you have you Django app deployed with Guincorn and Nginix, does every client request get its own instantiation of that middleware class? Or do they all share the same instantiation of that object in memory wherever your code is deployed? (or does each of Gunicorn's workers create its own instantiation?)

I Made Spotify Premium, But This Time It's Free
A while ago, I shared how I built a Python script to download my Spotify Liked Songs as MP3s. Since then, I decided to take the project one step further. Instead of manually running the script every time I added new songs, I’ve now automated the entire process to check for new liked songs every day and download them automatically.
Here’s how it works:
- Extracts my Liked Songs from Spotify using the spotipy library.
- Compares them with the list of songs already downloaded to avoid duplicates.
- Uses youtubesearchpython to find the top YouTube result for any new songs.
- Downloads the audio as an MP3 using yt-dlp and stores them in the Songs directory on my desktop.
It’s simple, but it now saves me even more time. I no longer have to worry about manually managing my favorite songs!
This project was so fun to work on, and now I've made it even smarter, by making it run automatically using the Windows built-in Task Scheduler!
I was thinking of making this like a paid tool, with a small cost of $2, but I figured let's share this with people so they can also benefit :)

I'm sorry oif this is not the right space but I didn't have someone to share this and would actually understand my happiness.
I was finally able to deploy my Django application on Digital Ocean with Postgres, Nginx, and Gunicorn on its Ubuntu machine. I also pointed my domain to the IP and set up the SSL certification. This took me days and I had to destroy the machine multiple times. Oh I also configured redis and celery with different workers.
I'm so hyped 😂😂

How to configure celery?
I am currently running a flask backend server that is used for various features and one of the features I have added is a model for prediction that takes about 5 to 10 minutes to train on hitting an api on frontend which works fine but the api itself timesout after 2 minutes although the model still gets trained and stored for each user. Now issue is to prevent a mad user experience I wanted to train the model in background and came across celery with redis which I was already for storing sessions so thought to use it and everything runs only just when I use @shared_task decorator to run my task it give Error 61 of connection refused although on running the celery command and backend it says celery is connected. Can someone help me here?
Edit - I used rabbitmq as the broker and redis as result backend and everything worked smoothly. Thanks everyone

# GitHub:
[https://github.com/hlop3z/zmag/](https://github.com/hlop3z/zmag/)
# What My Project Does:
ZMAG is a framework designed for building **network APIs** rather than traditional web applications, leveraging the unique combination of **GraphQL** and **ZeroMQ**. With **ZeroMQ** you can create different system. Examples:
* **Request / Response**
* **Push / Pull**
* **Publish / Subscribe**
# Target Audience:
Currently is a toy project, I’m going to use it to manage projects internally, which I made with Django and FastAPI.
# Comparison:
As far as I know there’s nothing that combines **GraphQL** and **ZeroMQ** into a framework. Something similar I know that exist but not with GraphQL is [https://www.zerorpc.io/](https://www.zerorpc.io/)

Python 3.13's best new features
Everyone has their own take on this topic and here is mine as both a video and an article.
I'm coming with the perspective of someone who works with newer Python programmers very often.
My favorite feature by far is the new Python REPL. In particular:
- Block-level editing, which is a huge relief for folks who live code or make heavy use of the REPL
- Smart pasting: pasting blocks of code just works now
- Smart copying: thanks to history mode (with F2) copying code typed in the REPL is much easier
- Little niceities: exit exits, Ctrl-L clears the screen even on Windows, hitting tab inserts 4 spaces
The other 2 big improvements that many Python users will notice:
- Virtual environments are now git-ignored by default (they have their own self-ignoring .gitignore file, which is brilliant)
- PDB got 2 fixes that make it much less frustrating: breakpoints start at the breakpoint and not after and running Python expressions works even when they start with help, list, next, or another PDB command
These are just my takes on the widely impactful new features, after a couple months of playing with 3.13. I'd love to hear your take on what the best new features are.

Niquests v3.9.0 Released
We are proud to announce our latest advancement for Niquests. Since last time we published in
this community, a lot of things happened.
We landed for you:
- Post-Quantum Security for QUIC
- QUIC v2
- Integrated WebSocket Support
- HTTP Trailers
- Early Responses like "103 Early Hints"
- Happy EyeBalls
The project reached 800+ stars with half a million downloads since the beginning.
We are grateful to Microsoft and involved parties for funding our work through the Microsoft FOSS Fund program.
What My Project Does
Niquests is a HTTP Client. It aims to continue and expand the well established Requests library.
For many years now, Requests has been frozen. Being left in a vegetative state and not evolving,
this blocked millions of developers from using more advanced features.
Target Audience
It is a production ready solution. So everyone is potentially concerned.
Comparison
Niquests is the only HTTP client capable of serving HTTP/1.1, HTTP/2, and HTTP/3 automatically.
The project went deep into the protocols (early responses, trailer headers, etc...) and all related
networking essentials (like DNS-over-HTTPS, advanced performance metering, etc..)

I love Django! I don't use any third party django extensions, am I missing out?
Hello everyone,
Django has been really good lately for the different applications I use. Beyond the code, even the philosophy of Django has helped me structured my thinking. I also started using Cookie Cutter, that stuff is awesome. I have been tempted to use certain django extensions such as Django Markdown (for supporting markdown) and Django Ledger (for accounting stuff I knew now much about).
In the end, I didn't implement neither because I found alternative solutions. I would really love hearing from the community?
1. Do you stand by any specific django extensions that you use in your projects?
2. How is your experience like as a someone who contributes to extensions?
3. What were some of your negative experiences with extensions?

Just Released Version 0.5.0 of Django Action Triggers!
First off, a huge thank you to everyone who provided feedback after the release of version 0.1.0! I've taken your input to heart and have been hard at work iterating and improving this tool. I’m excited to announce the release of version 0.5.0 of django-action-triggers.
There’s still more to come in terms of features and addressing suggestions, but here’s an overview of the current progress.
# What is Django Action Triggers
Django Action Triggers is a Django library that lets you trigger specific actions based on database events, detected via Django Signals. With this library, you can configure actions that run asynchronously when certain triggers (e.g., a model save) are detected.
For example, you could set up a trigger that hits a webhook and sends a message to AWS SQS whenever a new sale record is saved.
# Supported Integrations?
Here’s an overview of what integrations are currently supported:
Webhooks
RabbitMQ
Kafka
Redis
AWS SQS (Simple Queue Service)
AWS SNS (Simple Notification Service)
AWS Lambda (New in version 0.5.0)
GCP Pub/Sub (New in version 0.5.0)
# Comparison
The closest alternative I've come across is Debezium. Debezium allows streaming changes from databases. This project is different and is more suited for people who want a Django integration in the form of a library. Debezium on

> - An experimental free-threaded build mode, which disables the Global Interpreter Lock, allowing threads to run more concurrently. The build mode is available as an experimental feature in the Windows and macOS installers as well.
> - A preliminary, experimental JIT, providing the ground work for significant performance improvements.
> - The locals() builtin function (and its C equivalent) now has well-defined semantics when mutating the returned mapping, which allows debuggers to operate more consistently.
