Django Ninja vs DRF for Async ? Seeking Advice
Hey everyone,
We’re building an API for our app, and while we really want to use Django, we need robust async capabilities since we’ll be making external API requests (e.g., OpenAI, LLMs).
We’re torn between Django REST Framework (DRF) and Django Ninja. While Django Ninja supports async out of the box and looks very developer-friendly, we’re concerned about its long-term support and community size compared to DRF. Future-proofing our app is important since this API will be a core part of our project.
For those who have used Django Ninja in production, would you recommend it? What are your experiences with its stability and scalability?
If not Django Ninja, how would you approach incorporating async functionality into a DRF-based API? Any advice or recommendations would be greatly appreciated! We will definitely use Celery for some tasks but rn we're looking for a solution for immediate responses.
Thanks in advance! 🙏
P.S. We also need robust permission handling since we need to be HIPAA compliant.

blackjack from 100 days of python code.
Wow. This was rough on me. This is the 3rd version after I got lost in the sauce of my own spaghetti code. So nested in statements I gave my code the bird.
Things I learned:
write your pseudo code. if you don't know **how** you'll do your pseudo code, research on the front end.
always! debug before writing a block of something
if you don't understand what you wrote when you wrote it, you wont understand it later. Breakdown functions into something logical, then test them step by step.
good times. Any pointers would be much appreciated. Thanks everyone :)

Need Help deploying React + Flask
Hi, flask newbie here
i spent quite a while developing a react and flask application thats pretty simple,
react fronend, sends post requests and get requests to flask backend, uses routing aswell.
i had it up working fine with localhost:5000 and localhost:3000 and now I'm trying to deploy it,
tried to use Dockerfile with render and deploy them both at the same time, ended up being really frustrating so i switched to using a digitalocean droplet, and following a tutorial that got me setup with nginx, but because my flask backed doesnt really display anything i am having trouble debugging - i set up a system service on the droplet (just a linux vm) so a gunicorn process is alway running, but i cant visit it properly. also i have a domain but it doenst seemt o work with nginx.
any advice on deployment?
Thanks

Bagels v0.3 update! Expense tracker that lives in your terminal.
Hi r/Python! I'm excited to share about the launch of Bagels 0.3 - a terminal (UI) expense tracker built with the textual TUI library! Check out the git repo for screenshots!
This new major version adds a whole new manager page, equipped with a display of 3 new plots (spending per day, cummulative spending trajectory and balance over time). The new budget section is designed to assist with saving part of your income and limit unnecessary spending!
The plotting is implemented with plotext!
# Target audience
Pain point: I find it annoying that my mobile budget tracker often gets out of sync with my actual balance when a record is missing, and I have no clue when that was. Also, it was frustrating that the most feature-rich budget trackers require you to pay to export your data.
Bagels is designed for you to conveniently enter your records at the end of each day, and store them in sqlite for easy export and processing if needed!
Comparison: Unlike traditional expense trackers that are accessed by web or mobile, Bagels lives in your terminal. Intended for you to check in and add records for the day, instead of doing so on the go with a mobile app.

Quick Question - New to Flask
I created a python script that generates the "Turning LED on" text in a web browser using the Flask API. After finding success with printing the text to the web browser, I attempted to import the GPIOZERO library and use the script to literally turn on an LED. Unfortunately, I cannot get it to work. I would appreciate any help with troubleshooting the code.
I tried creating local variables under the defined method. Please see below:
from flask import Flask
from gpiozero import LED
app = Flask(\_\_name\_\_)
u/app.route('/led/on')
def led\_on():
return "Turning on the LED"
return {'status': True}
led = LED(17)
green.on()
u/app.route('/led/off')
def led\_off():
return "Turning off the LED"
led = LED(17)
green.off()

Open Source Load Testing with Locust: 13 years, 60 million downloads later
Hi, maintainer of Locust, the popular load testing tool for Python here 👋
Recently our project turned 13 years old, got its 25,000th GitHub star AND 60 millionth download*, so I figured now might be a good time to look back a little.
In fact, I wrote a whole blog article about it. The TL;DR of it is
* Expressing load tests in Python is still much more powerful than clicking around in a GUI
* Open source is fun, messy and benefits greatly from automated testing
* We're going to do tons of new stuff going forward (AsyncIO, freethreading, extended protocol support). Let me know if you want to contribute! There's also a hosted version nowadays (Locust Cloud)
A big shout out and thanks to the almost 300 people who have contributed so far. You rock.
Let me know if you have any comments on the article or on Locust in general, happy to answer any questions :)
* The truth is that nobody knows how many times Python packages have been downloaded, due to mirrors etc, but at least this one says its 61.3M https://pepy.tech/projects/locust?timeRange=threeMonths&category=version&includeCIDownloads=true&granularity=daily&viewType=chart&versions=2.32.7.dev14%2C2.32.7.dev9%2C2.32.7.dev8

Rotate refresh tokens in JWT
Hi. If anyone has worked with JWT tokens where rotate refresh tokens is set to True, can you please explain how rotation works?
For example, below is my simple JWT settings.
ACCESSTOKENLIFETIME": timedelta(minutes=5), "REFRESHTOKENLIFETIME": timedelta(days=1), "ROTATEREFRESHTOKENS": True, "BLACKLISTAFTERROTATION": True.
Here’s how I think it works:
1. when the access token expires after 5 minutes, user requests a new access token using the refresh token (let's call it RT1) .
2. Along with the access token, a new refresh token (RT2) is sent to the user. RT1 is invalidated/blacklisted.
3. when again this new access token expires after 5 minutes, RT2 is used for requesting the new access token.
I believe I have understood the process correctly so far.
My question is, what is the validity of RT2? Is it 1 day from the time RT2 was issued or 1 day from the time RT1 was issued?
If it’s the former, then rotation keeps happening, and the user will remain logged in until they explicitly log out of the application. Am I right? If yes, then specifying a 1-day validity for the refresh token would serve no purpose.
If it's the latter, then the subsequent refresh tokens after RT1 will not have 1 day validity.

Any reason to NOT use Pyright?
Based on this comparison (by Microsoft): https://htmlpreview.github.io/?https://github.com/python/typing/blob/main/conformance/results/results.html
It seems Pyright more or less implements nearly every specification in the Python Type System, while it's competitors are still lagging behind. Is there even any reason to not use Pyright (other than it relying on Node.js, but I don't think it's that big of a deal)? I know MyPy is the so-called 'Reference Implementation' but for a Reference Implementation it sure is lagging behind a lot.
EDIT: I context is which Type Checker is best to use as a Language Server, rather than CI/CD.

Anthropic CEO says at the beginning of 2024, models scored ~3% at SWE-bench. Ten months later, we were at 50%. He thinks in another year we’ll probably be at 90% N
"One of the reasons I'm optimistic about the rapid progress of powerful AI is that, if you extrapolate the next few points on the curve, we’re quickly approaching human-level ability.
Some of the new models we've developed, as well as reasoning models from other companies, are starting to reach what I’d consider PhD or professional level. For example, our latest model, Sonnet 3.5, gets about 50% on SWE-bench, which is a benchmark for professional real-world software engineering tasks. At the start of the year, the state of the art was only around 3 or 4%. In just 10 months, we've gone from 3% to 50% on this task. I believe in another year, we could reach 90%.
We've seen similar advancements in graduate-level math, physics, and biology, with models like OpenAI’s GPT-3. If we continue to extrapolate this progress, in a few years, these models could surpass the highest professional human levels in skill.
Now, will that progress continue? There are various reasons why it might not, but if the current trajectory holds, that's where we're headed."

Resurrected: Announcing django-guardian 3.0.0rc1
Hi All,
Our beloved django-guardian (object level permissions for django) went unmaintained for a long time. After a lot of patience we've managed to resurrect the project and get all the permissions in place for the associated github, pypi, rtd accounts etc.
Today I released 3.0.0rc1 which brings django version support up to date and containes a whole ton of bugfixes, doc improvements and minor features. I'm very confident in it and expect to make this a full release over the next couple of months.
In this PR I explain why we've made this a major version release, although this shouldn't break your setup and *should* be a drop in replacement.
If you try this, please post because I want to hear your experience!

I made this using Django and tailwind
I’ve been learning Django for the past year and working on various small projects. While searching for ideas to build a project that could solve real-time problems, one of my photographer friends suggested an idea: "Hey AJ, can you build something where I can share and showcase my event photos with clients?" (He’s a wedding photographer.) He wanted a way to share photos of live weddings through a website, using a QR code.
Inspired by this, I built **ShareMySnaps** —a platform that allows users to create digital albums in minutes. Although there are many products available in the market, this project was entirely for my learning experience.
Here are some features of the app:
1. Users need to sign up via their Google account.
2. On the dashboard, users can create a folder, which will automatically be created in their Google Drive.
3. When users click to upload an image, they are redirected to their Google Drive page to upload.
4. Users can download a beautiful QR code that links to their gallery page.
5. The gallery page fetches all the photos from the specific folder and showcases them on the gallery website.
6. Each gallery has its own dedicated page, and these pages are customizable (currently, the

deidentification - A Python tool for removing personal information from text using NLP
I'm excited to share a tool I created for automatically identifying and removing personal information from text documents using Natural Language Processing. It is both a CLI tool and an API.
https://github.com/jftuga/deidentification
https://pypi.org/project/text-deidentification
What my project does:
Identifies and replaces person names using spaCy's transformer model
Converts gender-specific pronouns to neutral alternatives
Handles possessives and hyphenated names
Offers HTML output with color-coded replacements
Target Audience:
This is aimed at production use.
Comparison:
I have not found another open-source tool that performs the same task. If you happen to know of one, please share it.
**Technical highlights:**
* Uses spaCy's transformer model for accurate Named Entity Recognition
* Handles Unicode variants and mixed encodings intelligently
* Caches metadata for quick reprocessing
Here's a quick example:
Input: John Smith's report was excellent. He clearly understands the topic.
Output: [PERSON]'s report was excellent. HE/SHE clearly understands the topic.
This was a fun project to work on - especially solving the challenge of maintaining correct character positions during replacements. The backwards processing approach was a neat solution to avoid recalculating positions after each replacement.
Check out the deidentification GitHub repo for more details and examples. I also wrote a blog post which goes into more details.
