Project to quantize/perfect/vectorize loose scribbles

Any points on how I would go about doing that in python? So a loose, sloppy oval straightens out into a perfect oval estimated into the orientation size that the more sloppy version seemed intent to be, and the same thing with lines, circles, squares, trianges, etc.
I think it'd be a path for a program, perhaps Kivy -> iPad, something like that. Any thoughts? Or is there something notable out there that does this?

Python Flask code improvement - ChatGPT prompt

I'm wondering if folks here have good prompts specifically for Python Flask, or if I can improve mine. Note - some instructions are specific for VSCode / pylint.
Here is my prompt in a GPT:
https://chat.openai.com/g/g-6b2rOEWL7-python-flask-code-optimizer

The prompt used::
Objective: Enhance the quality of Python code for applications utilizing Flask, SQLAlchemy ORM, and WTF forms. The goal is to ensure the code is production-ready, adhering to high-quality standards, including PEP 8 compliance, with an emphasis on robust error handling, readability, and efficiency.

Requirements:
\- Code Quality: Optimize code to be clean, efficient, and maintainable. Ensure adherence to PEP 8 guidelines for Python code styling and format.
\- Error Handling: Implement comprehensive error handling mechanisms to manage and mitigate potential runtime errors effectively.
\- Readability: Improve code readability through clear naming conventions, succinct but informative docstrings, and logical structuring.
\- Type Annotations: Apply precise type annotations to functions and variables to enhance code clarity and predictability.
\- Documentation: Include detailed, succinct docstrings for all functions and classes, providing a clear explanation of their purpose, parameters, and return types.
\- Logging: Adopt lazy % formatting in logging functions to optimize performance and

Real-time ingestion pipeline for RAG app in Python

Hi, I am working on a stream processing framework called Bytewax and I recently gave a talk where I read live data from HackerNews API, cleaned it with unstructured.io, created embeddings with a hugging face model, and stored everything in Milvus.

I find a lot of devs are struggling with real-time streaming. The steps are easy to follow, and it is an end-to-end Python: https://github.com/bytewax/real-time-milvus
I also added diagrams and summarized it in a blog https://bytewax.io/blog/stream-process-embed-repeat

How to translate consumers?

I have text I want to translate in my consumers. Unfortunately, the translation doesn't seem to take effect.

I'm able to mark the strings I want to translate for translation, translate them in the .po file and compile it but if I choose the language I translated thoses strings in my website, those strings aren't translated and still appear in the language they were written in.

Maybe I need to use gettext_lazy? In that case, how to I send the text marked with gettext_lazy to the WebSocket? it makes the text non json serializable.

How to I translate text that is in a consumer file?

Django, Bootstrap and CSS doubts

Hi, I'm new to Django, learning how to make backend mostly, but I want to make some projects and use some CSS in them. I already seem some things related, but I have a few questions.

Is Bootstrap the standard for fronted Django? Is it the only way to edit forms with CSS? If I don't use Bootstrap how can I edit forms with CSS? I now that for the most part you won't be using Django as a fronted framework, but I still have this questions

Valid uses of eval()?

I’m wondering if anyone has ever seen a case of code using eval() and thought to themselves “yeah actually that’s probably the right way to do it”?

My understanding has always been that it’s a huge security risk and generally a recipe for disaster.

But I was just working on a task where I couldn’t really figure out any other way to achieve the dynamic functionality I was looking for, so I wrote code that assembles a string to do what I need, and then runs eval() on that string. Pretty sure this is the first time I’ve ever used eval() at all.

It’s a low-stakes proof of concept for a totally internal tool, so I’m not hugely worried about security at the moment, but it just feels so icky to do something like that. I’m curious if in others’ experience there’s always a better way than using eval(), or if sometimes it’s legit.

hi everyone, for one of my projects, I have to develop a spell checker in practically all the languages ​​supported by OPENAI, and I thought why not share it with everyone!

IS HTML Semantics Supported by all Browsers?

As part of a final exam project, I'm expected to include accessibility features to my website. Can I use HTML Semantic tags? Some websites state that it should be used to support users with disability. Other websites say that some browsers do not support it.

I'm confused now. Please advise.

Where to learn Django like Flask Mega-Tutorial from Miguel Grinberg?

I learned how to use Flask by following Miguel Grinberg's Flask Mega tutorial, which was great. I learned how to build and deploy a Flask microservice web app and what it looks like to write clean and effective code for the app which makes me (a beginner) feel like he writing an industry-standard code layout. Is there any tutorial or book similar to this in Django?

How to manage vercel deployment?

Currently I am using vercel to deploy a django app for a project I maintain but one of the difficulties I've encountered is that it doesn't look like there's a way access the shell (so I can't run manage.py commands to do things like create a superuser). One of the ideas I had was to automatically create a supper user through secrets on deploy, but I haven't fully investigated it yet.

I am mainly using vercel so I can use its free tier to very the software / provide instructions to the person on the team who will be paying for the real deployment once we officially release. If there's a better alternative for this (I am using Vercel + Vercel Postgres + Vercel Blob right now) please let me know.

One of the dumber ideas I thought of was temporarily adding an endpoint to inject in the user creation and then close it up after I was done.

Also one of the things I'd like to do is run custom management commands (basically for DB management/pruning/exporting). Are there any integrations for Django Admin that allow for this?

An extremely modern and configurable Python project template

# What My Project Does

Rob's Awesome Python Template is a cookiecutter template meant to bootstrap python projects using modern best practices.

At the very basic level it includes:

- Modern pyproject.toml without any legacy files (no setup.py or setup.cfg).
- Development Management using Makefiles.
- Configuration Management with Pydantic.
- PyPI Publishing from Git Tags using setuptools-scm.
- Formatting and Linting with Ruff.
- Typing with mypy.
- Lockfiles (requirements.txt, requirements-dev.txt) with uv.
- Testing with pytest.
- CI/CD using Github Actions.
- Precommit Hooks using the precommit framework.

It also has a ton of optional features:

- Github Actions for CI
- Cross Platform (arm, arm64, amd64) Docker containers using the Multi-Py project.
- Optionally use any combination of FastAPI, Click/Typer, Celery, and Sqlalchemy.

I've used this template for a number of projects- QuasiQueue, Paracelsus, and Fedimapper being some nice examples. If you want to see exactly what the project would generate today you can review the examples repository which builds a few projects using different options to give people a feel for what things can look like.

# Target Audience

Any developer looking to bootstrap their projects can use this! What makes it really helpful is that you get a modern, high quality project with tools already configured before you even write a single line of

Hi,

I am working in a django repo where the views and the forms and the all the things inherit and inherit some more.

How do you guys manage to get an understanding of what the actual resulting methods and properties of any given class is? Do you lean into the ide capabilities (which? how??) or do you guys have a protocol?

When exactly should you use .js when using a flask db

Hi all, I'm trying to figure something out. Since I started writing my website, anything that involved modifying my database I would do an onclick call to a .js routine. But as I've gotten further and seen other peoples code I'm seeing that is not necessary as it can simply be done through routing and forms. I was doing it simply because the original tutorial I followed used .js. Is there some reason I'm not seeing? And generally speaking when is it a good idea to start mixing .js in?

Flask Admin does not hash the User password
