Understanding apps, forms, and the structure of a project/app

Hello everyone,

I am basically a beginner trying to use Django in order to build an app for a business I work for. I have experience with programming, but I never built any app (or web based one).

After going through the Tutorial of Django, I jumped and started programming.

I decided to use various apps instead of having one app because I couldn't focus on the tasks needed and it was a cluster of code.

I began with 2 applications: forms - allows essentially forms management/everything to do with forms: processing, validation etc, and users app - user management, authentication, user settings and so on.

I started to create a login form and login form view. the login form has its own clean methods, and the login form view allows me to forward the form and reder it in HTML loginForm/. I decided to render only the form itself, but I will have a proper "login/" page will the loginForm/ will be imported to. As I said earlier, it is because the forms app is only responsible for the forms, and the rest of the page will be done by something else.

after I wrote all of what I mentioned, I realized that Django has

Alternatives to Jinja for Flask-Based Desktop App Using PyInstaller and WebView

I'm developing a desktop application using the following tech stack:

Frontend: HTML, CSS, JavaScript, Jinja2 (current template engine)
Backend: Flask
Packaging: PyInstaller to create a `.exe`
UI: WebView for Windows

I am currently using Jinja2 for templating, but I want to explore other template engines that might provide better performance or additional features. My main requirements are:

1. Compatibility with Flask: Should integrate easily without much configuration.
2. Support for Desktop Apps: Must work well with PyInstaller when packaging the app.
3. Efficient Rendering: Performance is key, as the app is intended for desktop use.

Are there any good alternatives to Jinja2 that would fit well within this stack? Any advice on integration or potential challenges would be appreciated!

Thank you!

Introducing WSCE: A Custom Shell Environment Built with Python

Over the past few weeks, I've been working on a custom shell environment called **WSCE**. Built entirely in Python, it mimics the functionality of an operating system and comes packed with features like a fake boot sequence, a text editor, and more. It's designed to provide a unique experience that blends the line between an OS and a shell environment.

# What My Project Does

WSCE is a simulated operating system environment built as a Python-based shell. It offers a range of features such as:

* **FakeBoot:** Emulates the boot process of an actual operating system.
* **Aurora Text Editor:** A simple text editor to mimic basic productivity tools.
* **CommandSearch:** A script that searches a folder for python files to make into custom commands

# Target Audience

This project is primarily a passion project and is not intended for production use. It is targeted at hobbyists, Python developers, and those interested in exploring custom shell environments or unique OS simulations. It's perfect for those who enjoy tinkering with code and experimenting with unconventional software projects.

# Comparison to Existing Alternatives

WSCE stands out because it's not like any other shell environment or operating system out there. Unlike traditional shells or full OS environments, this project focuses on simulating

Nice looking, data display tables in Python? +Video

Ahoy, I wanted to share a video my buddies made. They maintain the great_tables package, a library for building pretty tables with Python, e.g. for publication or the web. If that's something you might want to do, you might want to check this out.

Here's their video, https://youtu.be/M5zwlb8OzS0
Here's the package doc site, https://posit-dev.github.io/great-tables/
Here's the repo, https://github.com/posit-dev/great-tables

Is Python easier to break into than other languages coming fron experience in a different stack?

Im looking to get out of.net because its a career dead end in my local area but no java jobs consider me even though i have spring boot projects. Python seems less opinionated with libraries like fastapi so i wonder if its easier to break in as a generalist.

What are you best tips for managing the database state with a small team?

Small team working on a SaaS project with Django as the back end. We're all new to Django, and we're running into issues where the database and migrations keep getting out of sync.

We use github, and are developing locally. I'm sure this is a super common problem with easy fixes, and advice?

D Efficient way to store large datasets

I’m collecting trajectories for imitation learning (RL) and each trajectory is about 1500 time steps long, consists of 4 image streams of about 600x600 pixels.
Obviously, the dataset size grows extremely quickly with the number of trajectories.

What are some good libraries for efficiently (in terms of disk space) storing such data? I tried h5py with level 9 gzip compression but the files are still way too large. Is there a better alternative?

Saving and loading times do not really matter.

Most resources online are aimed at efficiently loading large datasets or handling them in memory which is not relevant for my question.

I already use uint8 as datatype for the rgb streams.

Yet another 12 factor configuration helper : python-direnv

Hi Python! I've developed another app to manage environment variables.

# What My Project Does

This allows you to `load_direnv()` your environment variables like `load_dotenv()`, once you allow them through `direnv`, but unlocks the full power of the bash shell instead of being limited to basic key-value pairs. Contributions welcome (the package is not yet on Pypi.org, working on it) !

# Target Audience

If you are developing using the 12 factor app principles and are a user or direnv, Nix, or Guix you might want to check out this package I just wrote : https://github.com/nicolas-graves/python-direnv

# Comparison

This package is actually quite different to other similar projects. It doesn't use a parser but loads environment variables based on shell environment changes. This allows for instance full environment configuration using Nix or Guix for instance, thus providing a way to load a complete environment from a simple `__file__` variable, in any Python project. I have another project on the way that needed this for real-life application ;)

simple project suggestion

i don't know if this is the place to ask this but can you suggest a github repo of a simple (not necessarily) django project that inside it users can enter their information inside a form and then the website has a section that displays all these users somewhere, anything remotely close to this is good enough i'll change it up a little bit, its a project for my teacher but i don't have a lot of time to do it all myself, just need a simple local project, Thank you in advance

I've been tracking Python, Django, NumPy and several other frameworks in job listings this year

Hi all, I built a website to track programing languages/skills/frameworks in jobs.
Perhaps unsurprsingly Python is by far the biggest category in software engineering:

I'm tracking many other Python frameworks and libraries as well:

[Django](https://job.zip/trend/django)
Scikit-learn
[NumPy](https://job.zip/trend/numpy)
Flask
[FastAPI](https://job.zip/trend/fastapi)
Keras
[MicroPython](https://job.zip/trend/micropython)
Ruff

I hope this is of some use of you, if there's another framework you'd like me track, please let me know!

Also there's a Python component as well, I use Python to identify trends in my dataset. Every month I load up 10 million new jobs and compare them with the months before to identify new types of jobs to add to the site.
