Tailwindcss or bootstrap in 2024 ?

I like tailwindcss but once I spend two weeks without using it I forget a lot of class names. Also I end up just copy pasting whatever free design I get which is not really deep learning. But I do hate how much it makes my html pages clutered, especially since I mostly build server rendered websites.
Bootstrap seems fine, with way less classes to put on the html so, I hesitate to double down on bootstrap

How to handle file uploads with Flask, PostgreSQL, and markdown with restricted access?

I'm working on a Flask application where users can upload various types of files. Here are some examples of how file uploads are used:

Users upload profile pictures or company logos.
When creating a job, users can write a denoscription in markdown that includes image/file uploads for visualization.
Jobs have "Items" (similar to jobs), which also include markdown denoscriptions with image/file uploads.
Users can comment on Jobs and Items, and the comments can include multiple images/files.

Each of these objects corresponds to a PostgreSQL model (User, Company, Job, Item, Comment), and each model already has CRUD APIs and an authorization map. For example, only users in a company can see Jobs related to that company.

# My Requirements:

1. I want to handle file uploads and display them properly in markdown (like pasting an image and getting a URL).
2. I need to restrict access to image URLs based on the same authorization map as the object that owns the image (e.g., images in a comment should only be visible to authorized users).
3. Images/files should "live" with the object that references them. If the object (e.g., a comment) is deleted, the associated images/files should also be deleted.

# Example Flow:

1. A user starts writing a

Dependency injections in Django/Python

Hi, i have a PHP and Java background, i recently started using django to build a basic weather app just to learn the framework. i found out that django doesn't provide a container or binder, so i presume that in python we are supposed to avoid tight coupling some other way. what is the convention to inject an helper class in another? should i use a different paradigm all along? i've thought of constructing them in the \_\_init\_\_.py, but that feels wrong to me. for now i'm simply passing an instance of the object i need when i construct the object in the views file.

pretty much like that

I Understand Machine Learning with Numpy and PyTorch Better Since I Started Focusing on the Basics

I've recently started appreciating ML in Python more since I began looking at the concepts from the ground up.

For example, I took a closer look at the basics of classification neural networks, and now I have a better understanding of how more complex networks work. The foundation here is logistic regression, and understanding that has really helped me grasp the overall concepts better. It also helped me implementing the code in Numpy and in PyTorch.

If you're also interested in Machine Learning with Python and sometimes feel overwhelmed by all the complicated topics, I really recommend going back to the basics. I've made a video where I explain logistic regression step by step using a simple example.

The video will be attached here: https://youtu.be/EB4pqThgats?si=Z-lXOjuNKEP5Yehn

I'd be happy if you could take a look and give me some feedback! I'm curious to hear what you think of my approach and if you have any tips on how to make it even clearer.

* [Simplified logic](https://github.com/baseplate-admin/django-hstore-widget/blob/67e17e0da3e8e413bc23b36ac0f403a823687f52/src/components/django-hstore-widget/django-hstore-widget.tsx) compared to [django-admin-hstore-widget](https://github.com/PokaInc/django-admin-hstore-widget/blob/8a19511403f0dd5d64c350efbed96c01d1a6544e/django_admin_hstore_widget/templates/django_admin_hstore_widget.html)
* Uses emoji as fallback.
* No hard dependency on `jQuery` / `underscore`
* Reduced bundle size.
* [Automated publishing using github actions](https://github.com/baseplate-admin/django-hstore-widget/blob/67e17e0da3e8e413bc23b36ac0f403a823687f52/.github/workflows/CI.yml).
* Dropped support for old browsers.
* Based on web-components


With that being said, i would really appreciate if you guys check the package.

Determined to start and deploy webapp before the end of the year

I am super brand new to web development and I know my current passion and determination and confidence is part of the Dunning-Kruger effect

I’m fully aware I know nothing, not even a strong foundation in python

However this week I have built the essential codes for the main product of the web app using colab and chatpgt

I’ll be reinstalling python on my machine (did it wrong the first time lol get to eager and didn’t click on the little box asking about Paths)

Hope it’s okay if I use this group to keep myself accountable and share my journey especially when I eventually realise how much I really don’t know and lose some of my confidence lol

Also the app is meant to be my financial freedom project so with some luck I really do believe I can create something into being that other people will find true value in

Wish me luck x

When working with multiple threads working on one model object, is there something about related fields that saves the primary objects data?

I have some celery tasks that run at the same time working on one model object. I'd thought I had been very careful about using transactions.atomic and select_for_update and using update_fields...etc.

I've run into one scenario i cannot explain

`conversion_successful` calls `.delay` on two other tasks and then updated a field on the object, as such:

load_skips.delay(pk=pk)
send_notification.delay(pk=pk)

with transaction.atomic():
m= MyModel.objects.select_for_update().get(pk=pk)
m.system_notes['processing_finished'] = timezone.now().isoformat()
m.save()

However what keeps happening is that the `processing_finished` in `system_notes` is very hit an miss as to whether or not it ends up in `system_notes` at the end of the day.

I tested moving the call to the two other tasks AFTER commiting the `processing_finished` data and its 100% always there. So there's something going on in those other two tasks.

The thing is, the other two tasks are a notification task which only get()'s the model and never saves, while the second task is loading data into a related model like the following:

m = MyModel.objects.get(pk=pk)
m.skips.get_or_create(

Production server help?

This is for my work. I can’t go into it too much here. Currently I am using waitress server. I am getting acceptable performance but I need to improve it. I am using nginx and waitress. Nginx for serving static and acting as reverse proxy. I have done lots of research and alternative options but the problem comes down to is Windows. This is a hard set requirement that it needs to run on windows. I can’t use gunicorn because it doesn’t support windows. I read about CHERRYPY WSGI SERVER - not sure about performance, uWSGI - (but I read it is made for Unix system), I read about hypercorn (I know this is asynchronous server) but it said in documentation that is can be served as sync. I don’t know about the performance. I am not sure.
What are some alternatives web servers that I can use and runs on windows that will give better performance than waitress?
I am pretty new to this so I greatly appreciate for helping me guide to the right direction.

Environments Utils - Detect Your (quirky) Python Runtime Environment

Hey, r/Python!

What My Project Does:

Over the years, I’ve been working on a Python package called **Environments Utils** that helps detect characteristics of the environments where your Python noscript is running. It’s built to handle various edge cases and odd environments I’ve encountered. For example, it can determine if your noscript runs inside a Jupyter Notebook, on a SLURM cluster, or within Rosetta on macOS. The package also identifies system architecture, operating system, GPU availability, and even whether you have an internet connection - all with no additional dependencies!

Target Audience:

This package is designed for developers and data scientists who work in diverse environments, such as cloud platforms and high-performance computing clusters. I find it particularly useful when I need to adapt a pipeline depending on which system it is being installed on.

Production Use: You can use the package to adapt your noscript's behaviour based on the runtime environment (e.g., using different logging mechanisms in a SLURM cluster).
Development/Debugging: If you're writing code that needs to adapt to odd environments like Colab, TMUX, or hybrids like macOS Rosetta, this package can save you some headaches. I had several noscripts that only broke down in COLAB or Rosetta etc, and this made

rendertemplate refuses to find my html file

hello! i am building a basic flask web app and cannot get render\template to correctly find my html file. i have scoured the web and tried many solutions, but it still says "template file 'index.html' not found". for reference my IDE is PyCharm. I have tried moving index.html in the exact same directory as the app, putting index.html inside a folder called "templates", and giving the Flask object a second input of "template_folder=[file path\]". None of these solutions work. My app.py is shown below (the if name==main part is below it with correct syntax, that just wasn't relevant here). Both app.py and the templates folder are in the same directory.

app=Flask(name)
