Can you share tutorials on django channels?

Hi I am building a app which creates a chat room in a local network for sending messages and files. This is my semester's final project and I thought how hard could it be. I knew how to use python sockets to make this work and thought how hard could it be to integrate it with django. I bit off way more than I could chew.


All I want it that the page updates it real time to display message. From what I read online I have to use websockets and channels to accomplish this, but I have no idea how any of this works. I have seen tutorials online and they all are too complicated and I am overwhelmed. Is there another way around this. All I want is to establish a connection between sockets and django channels. Please help

Integrating Node-RED and Django for Easy Smart Applications Development

Hi Redditors! 👋

I’m excited to share my latest project:
**Node-RED - Django Integration**, which aims to combine **Node-RED**, a fantastic tool for visually building flows, with **Django**, one of the most popular frameworks for web application development.

# What Makes This Project Unique?

In Node-RED, you cannot control user access permissions.

* For example, if you want one user to view a device's readings but not modify them, while another user can both view and edit the device's readings, this is impossible in Node-RED.
* In Django, advanced permission handling is possible.
* You can define specific permissions for each device, allowing precise control over who can view or modify data.
* However, in Django, it is challenging to connect and manage multiple devices or control the flow of data.
* Unlike Node-RED, Django is not designed for creating seamless data flows or automation

Why This Project?

I wanted to explore the possibility of simplifying the development of smart applications using flexible and accessible tools. The goal is to empower developers to create fast, efficient applications by leveraging the strengths of both Node-RED and Django.

Hardening my Django server

I've had a Django app running on a Digital Ocean droplet for several years without issue. Lately it would run out of memory on complex queries. The CPU was also hitting high levels. I decided to move to a Hetzner VM - 4 times the CPU and 4 times the memory for about the same price. Having updated all the software dependencies and dome lots of testing I finally migrated to the new server on Sunday. On Tuesday, by coincidence, I got a notification from Digital Ocean Security saying that they had received a report that my old DO server was making unauthorized connection attempts on a remote third-party server via SSH. As I now no longer needed that server, I responded by destroying it. (I don't have the time and expertise to analyse exactly what was going on.

Of course, I want to avoid such an issue recurring on the new server. So my question is: What measures beyond the standard Django deployment checklist (which I had followed) do you recommend for your Django servers? I'm using Nginx and Gunicorn on an ARM platform. I'm thinking of libraries like fail2ban, maybe a Web Application Firewall, scanners for malicious code

TIL: uv pip install doesn't compile bytecode installation

uv pip install is way faster than pip install, but today I learned that is not a completely fair comparison out of the box. By default, pip will compile .py files to .pyc as part of installation, and uv will not. That being said, uv is still faster even once you enable bytecode compilation (and you might want to if you're e.g. building a Docker image), but it's not as fast.

Setting Up Django for Success

Hello everyone,

I wrote a getting started guide I wish I had myself when I got started with Django around 8 years ago. It goes from setting up a virtual environment using `uv` to having a server side rendered front-end application hydrated using Vue. I tried to write it in such a way that you could achieve the same by using React/Svelte instead of Vue by only changing the Vite template. It contains a short piece of Django Rest Framework to demonstrate persistence via an authenticated API.

It's a collection of ideas that worked for me and others in the Django community. Some from books such as Two Scoops of Django. Others from resources such as LearnDjango.com or DjangoCon US talks. Of course duly credited where mentioned.

https://jilles.me/setting-up-django-for-success/

Hopefully there is something useful in there for everyone. I think it's a nice middle-ground between a completely empty Django project and a fully fledged django-cookiecutter.

Unable to create virtual environment

I just started learning Flask and want to create a virtual environment within VSCode. I did install the virtualenv package using pip

pip install virtualenv

But when I enter the prompt "virtualenv env" to create a directory, I get a file not found error saying that "system cannot find file specified".

Why am I getting this error and how can I fix this?

Best practice for allowing access to users without an account

I need to provide access to users who don't have an account on the site, and I want it to be properly routed. We manage condo associations, and want to let tenants report problems. Owners are no problem, they already have a website account to pay condo fees etc. But tenants don't. Is there a better way to do it than just giving them a url with a long UUID (ie domain.com/request/\[UUID\](http://domain.com/request/UUID) or similar) where the UUID would be tied to a particular unit so we could share it with the appropriate condo board?

D Comment on CVPR reviews and ICLR decisions.

Hey everyone,
We all know how reviews and decisions can be controversial, and I’m sure many of you are feeling disappointed with the results (My rating from CVPR is all 2 😅). But remember, it’s not the end of the world!

Rejection doesn’t mean you’re at fault—it’s often just bad luck (though, of course, we should always strive to improve our work).

Take a break—grab some chicken and beers, get a good night’s sleep, and gear up to submit your work to another venue. You’ve got this! 💪

Jypter Tries Opening in Photoshop instead of Browser

I am taking a Python class at my college, and as part of the class, we installed Anaconda and the Jypter Notebook to write our code in. Whenever I try to open Jypter Notebook, it opens up Photoshop on my laptop.

The TA for my class had me uninstall Photoshop, and it got Jypter Notebook to run. However, I need to keep Photoshop on my laptop for my internship, so I would prefer not to have to uninstall and re-install it.

Do y'all know a potential work around for this?

I appreciate any advice, thank you all.

Edit:
I just realized that i misspelled Juypter, my bad

How do I find internships?

Hey everyone. I'm currently on the lookout for a Django-related internship and wanted to ask for some advice. I've worked on quite a few Django projects. While I feel confident in my skills, I’m unsure how to approach finding the right internship opportunities.

For those of you who’ve landed Django internships, how did you do it? Did you find opportunities through specific job boards, open-source contributions, or cold emailing companies?

Any tips, resources, or strategies would be super helpful!
Thanks in advance.

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.

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.

Implementing Graceful Shutdown in a Flask Application with Gunicorn and Multiprocessing

I need to implement graceful shutdown in an application where there are two Flask servers (running on different ports) and a shared multiprocessing setup.

Assume Server 1 handles the actual API endpoints, while Server 2 collects metrics and has an endpoint for that. Here's the mock setup I’m working with:

import multiprocessing as mp
import os
import signal
import time

from typing import Dict
from flask import Flask, Response
from gunicorn.app.base import BaseApplication
from gunicorn.arbiter import Arbiter

import logging

LOGGER = logging.getLogger(name)

def numberofworkers():
return mp.cpucount() * 2 + 1

def handlerapp():
app = Flask(name)

u/app.route("/", methods="GET")
def index():
return "Hello, World!"
