Flask session data is shared across multiple tabs

I create a variable and store it in flask session(server side), now I open another tab and change the variable, now it reflects in both the tabs. How should I deal with separating data accross multiple tabs?

Can Your Networking Library Do This

I've been using a networking library for a while and getting some value out it. Especially when I'm dealing with complex collections of process, i.e. distributed processing. It turns out that some wacky ideas actually work, and as far as I know, dont work with any other tools. Here is the repo;

Can your networking library do this

This repo demonstrates what you might do once you have OSI application layering and a pretty fresh approach to network addressing, i.e. not IPv4, IPv6 or socket id or request id or channel id.

Please find a link to a blog in the README that describes what to do with the modules. Does anyone claim that there is an equivalent, or better? Does anyone think that this kind of capability is missing from current toolsets?

Goal Screener (my first python app)

What My Project Does
it takes your quests/goals as main and side and a picture, then it simply draw them on it and make it the background picture so you can visualize your quests, besides that in the app you can see the list of your goals and track one of them.
Target Audience:
this project was meant for my own needs and to help some people boost their productivity to reach their goals
Comparison:
i really didn't look that much for comparison but i think there is some extensions or widget to do that especially on phone, no one draws on the background l think, the idea is that backgrounds let you see your goals more often that's why i did it this way

here's the link to the code github if anyone's interested, and remember to give me your feedback so i can develop my skills for future projects

Generate a gradient between 2 colors in python.

Saving this here for future people. This method relies on a library i made called hueforge:

Installation: pip install hueforge
Code:

from hueforge import Color

startingcolor = Color('red') # You can use other color formats. to see all check the readme file
endingcolor = Color('orange red')
print(startingcolor.gradient(to=endingcolor, steps=5))

What are some of the best Django project ideas to work

Hi everyone,
I'm looking to expand my Django skills and wanted to ask the community for suggestions. What are some of the best Django projects for learning or improving your development skills? I'm open to both beginner and intermediate level projects, but ideally, I want something that will help me practice important concepts like authentication, databases, and building full-stack web apps.

I'm looking for ideas that will challenge me while also being fun and useful to build. Any project suggestions or resources to get started would be greatly appreciated!

Thanks in advance!

A blog project made with Wagtail CMS turned into one of the coolest coding experiences of my life!

Not too long ago, I fell in love with Django. It made creating websites feel like working on a fun Lego project without having to buy the actual Lego set, and without having to clean up after. I started making YT coding tutorials to give myself more excuses to code, and because explaining what I do out loud helped me learn better, and sharing what I love with others feels great, like I am part of a community.

At some point, someone I know noticed I loved to code and asked me to build them a blog site. I said "I am on it, totally!" But also, I was quietly panicking because I’d never made a blog before and hadn’t coded anything that involved a Content Management System in my life. Then I remembered seeing Wagtail CMS mentioned here on the Django Subreddit a few times. I figured, Why not give this a shot? So I jumped into Wagtail’s getting-started tutorial without overthinking it.

And you know what? Wagtail turned out to be so intuitive that I felt like I “got it” within a few hours. I was expecting it to take weeks, maybe even a month. I couldn’t believe it! I

I made a Report Generation and Project Management Tool Django Rest

Hi, I recently released my open-source project APTRS (Automated Penetration Testing Reporting System). It is an automated pentest report generation application built with the Django Rest framework.


What it does:

Enables users to create and manage projects while tracking their statuses.
Management of customers and their respective projects, as well as any associated security vulnerabilities.
Users can generate project reports in Word using a custom template, as well as in PDF and Excel formats.
Additionally, the application allows users to use the WYSIWYG CKEDITOR to input data and document vulnerabilities for report creation.


Target Audience:

Individual Security Consultant
Cyber Security Companies to manage projects and clients and create a report

Many similar tools exist, but most Python-based options do not support custom word templates. APTRS stands out by focusing on company needs with features for project management and status tracking. It also plans to introduce customer login functionality, a feature lacking in other open-source tools.

Tech Stack:

Python 3.9+ with Django Rest Framework
Postgresql
Redis
Vite + React Frontend


Here's the source: APTRS


In case you're interested, I have demo instances hosted in the cloud available at: https://live.aptrs.com/ (Default creds are sourav.kalal@aptrs.com & I-am-Weak-Password-Please-Change-Me) - Some APIs

Anybody else all the sudden unable to access Python downloads at python.org?

We have a number of jobs that download python distros from python.org/ftp, and they just started failing due to Access Denied errors. Anybody else seeing this? Is this intentional? Everything in https://www.python.org/downloads/source/ is going to Access Denied

edit: Either python.org got ransomeware'd or some admin pushed a bad config change. Could be infra issues too I suppose. Looks like that backlog card for saving a copy of the source for the versions we use to S3 and pulling from there just got moved to this sprint...

Localization in Django Rest Framework

I have a Django Rest Framework project that is handling REST apis and React + TS application for client side.

Now I need to add Localization to my application for multi language support and it needs to be done on server side, so that the strings can be changed from the admin panel easily. I have used i18n on client side in React before but we want to do it on server side.


What's the best way to handle this? I am going through the documentation: https://docs.djangoproject.com/en/5.1/topics/i18n/translation/ & https://www.django-rest-framework.org/topics/internationalization/ but can't wrap my head around it how will be handled on the client side in React? Everything need to be translated from Header to Footer and everything in between.


Thanks!

Am stuck at part 3 of Django - Writing your own app.

So at this part, I try to type in /polls/34 and get this response:



# Page not found (404)

|Request Method:|GET|
|:-|:-|
|Request URL:|http://127.0.0.1:8000/polls/34|

Using the URLconf defined in mysite.urls, Django tried these URL patterns, in this order:

1. [name='index']
2. <int:question_id>/ [name='detail']
3. <int:question_id>/results/ [name='results']
4. <int:question_id>/vote/ [name='vote']

The current path, polls/34, didn’t match any of these.


Why is that?

is 2depth nested model still good for production..?

hi, I am building an ecommerce and my model structures are like


Product - < OptionName -< OptionValue


2depth nested model, and I feel it is really difficult to handle create, update in drf serializer.. is 2depth a normal approach? or should I limit to 1depth?


also, any advice or ways to handle nested models for creations and updating?

Is there life beyond PyUnit/PyTest?

Some years ago, there were many alternatives to just using these: grappa, behave, for instance, with many less-popular alternatives around and thriving.

Today, if you check Snyk Advisor for these, or simply the repo, you will find them abandoned or worse, with security issues. To be sure, checking the Assertions category in Pypi will give you some alternatives, a few interesting ones based in a fluent API, for instance, but none of them are even remotely as popular as these ones. New tutorials don't even bother in telling people to look for alternatives.

Have we arrived to a point where Python is so mature that a single framework is enough to test it all?

Good Linux distribution to choose for a first-time Linux install

FYI: I'm posting this in two sub-reddits, so if this is not the right sub then let me know and I'll delete here.

Generally, the question is per the post.

Context: Long time Mac user who is now studying to be a software engineer, and beginning with Python and Django. 'Everyone' says you should use Linux on your home device, and do your best to get used to it as soon as practical. But without knowing too much about Linux yet (I've only used Mint briefly), let alone the strengths and weaknesses of the different distributions ...What is a good choice for a beginner who both (a) wants to learn a lot, while (b) not getting too frightened too early by something with an immense learning curve or shock vs familiarity with Mac OC and Windows.

Thanks for any tips and advice. Cheers.

I made a Python signal/slot library that works like Qt but without Qt dependency

Hi everyone!

**What My Project Does:**
I've been working on TSignal, a library that implements Qt-style signals and slots in pure Python. It handles async operations and thread communication automatically, making it easy to build event-driven applications without pulling in heavy dependencies.

**Target Audience:**
This is meant for production use, especially for:

* Python developers who like Qt's signal/slot pattern but don't want Qt as a dependency
* Anyone building async applications that need clean component communication
* Developers working with multi-threaded applications who want easier thread communication

**Comparison:**
While Qt provides a robust signal/slot system, it comes with the entire Qt framework. Other alternatives like PyPubSub or RxPY exist, but TSignal is unique because it:

* Provides Qt-like syntax without Qt dependencies
* Has native asyncio integration (unlike Qt)
* Handles thread-safety automatically (simpler than manual PyPubSub threading)
* Is much lighter than RxPY while keeping the essential event handling features

Here's a quick example:

@t_with_signals
class Counter:
@t_signal
def count_changed(self):
pass

My side project has gotten 420k downloads and 69 GitHub stars (noice!)

Hey Redditors! 👋

I couldn't think of a better place to share this achievement other than here with you lot. Sometimes the universe just comes together in such a way that makes you wonder if the simulation is winking back at you...

But now that I've grabbed your attention, allow me tell you a bit about my project.

# What My Project Does

ridgeplot is a Python package that provides a simple interface for plotting beautiful and interactive ridgeline plots within the extensive Plotly ecosystem.

Unfortunately, I can't share any screenshots here, but feel free to take a look at our **getting started guide** for some examples of what you can do with it.

# Target Audience

Anyone that needs to plot a ridgeline graph can use this library. That said, I expect it to be mainly used by people in the data science, data analytics, machine learning, and adjacent spaces.

# Comparison

If all you need is a simple ridgeline plot with Plotly without any bells and whistles, take a look at this example in their official docs. However, if you need more control over how the plot looks like, like plotting multiple traces per row, using different coloring options, or mixing KDEs and histograms, then I think

Causal Discovery Competition Winning Paper Discussion D

I’ve recently come across this post: https://thetourney.github.io/adia-report/ which describes the winning method for a casual discovery competition. It’s not really my field but I do have a reasonable understanding of GNNs and Causal Inference. Anyway, from the report I don’t understand precisely what the winning team was doing. Can anyone either link to a full paper or have a good intuitive and potentially step by step explanation of what they are doing?
