Cyantic - build complex objects from simple blueprints using pydantic

# What the project does

Cyantic lets you build complex types from simple blueprints in your pydantic models, with type-safety and validation built in.

**https://github.com/flywhl/cyantic**

* Type-safe blueprints with validation, since they are pydantic models.
* Reference other values using `@value:x.y.z`
* Import objects using `@import:x.y.z`
* Load data from environment variables using `@env:VAR`
* Define custom @hook handlers (see tests)

For my work, I have to instantiate a lot of `torch.Tensors`, and I wanted a way to do this from YAML specs (how I specify models). So I built a kind of middleware, which uses intermediary Pydantic models as blueprints, and instantiates them into full objects during pydantic's build process. Now I can pass in parameters (mean and standard deviation), and get a fully-built `Tensor` in a pydantic model.

This is now a library, Cyantic - named after cyanotype photography (i.e. the "blueprint").

# Target Audience

It's clearly useful for science/data-science work, esp as scientists start moving away from `dict`s to use pydantic.

I think this would also be useful for general config management, using the `@hooks` API. You can stitch YAML files together, re-use sections of YAML, etc..

# Comparisons

I haven't looked for alternatives, but would love to hear about other builder/aggregator libraries for pydantic.

I built a "CodePen for Django Templates"

Hi all,

I have built a online Django Template Playground that renders the template in the backend using Django's template engine, letting you even choose which version of Django to use.



It also support creating snippets, which allows sharing of specific template snippets in a cool “try, change & play with it” kind of way.
For example this snippet: https://tech-playground.com/snippet/literate-wonderful-kittiwake/



The whole thing is also a Django app in the background, which I will share some more on in the near future.

Python in DevOps: My Favorite Tools

Hey! 👋

I rely on Python to do a lot of Ops / DevOps-type automation: automate workflows, create dashboards, manage infrastructure, and build helpful tools. Over time, I’ve found some Python-based approaches that make these tasks much easier and more efficient. Here’s what I use:

Custom dashboards with Flask and Prometheus Client
Automating workflows Schedule, then RQ, then finally Airflow
Network analysis with Scapy
Click / Typer / Rich for CLI (Starting with Click, but always moving past it at some point)

And, of course, a bunch more.

I made a list here:

https://www.pulumi.com/blog/python-for-devops/

Then, for fun, I tried to use Python for everything in a single service - using dagger for the container and pulumi for the Infra. ( I work for pulumi bc I'm a big fan of being able to use Python this way :) )

Code: https://github.com/adamgordonbell/service-status-monitor

What am I missing in my list?

Automating video reframing in python

So I'm on a quest to automate video editing for my youtube channel as much as possible. Currently I'm trying to build a program that would basically auto reframe a horizontal video to a vertical one (from 16:9 to 9:16) while also keeping the speakers head in the frame. I tried resolving this with openCv library with the help of claude and chatgpt but it leads to a dead end. I'm simply stuck and don't know any alternatives because there's not much info on this problem.

Do you guys know a library i could use for this that I maybe haven't heard of? Maybe I'm overcomplicating and there's a software that does this for free, I find filmora's automatic reframing perfect but not sure if they'll block it off once my trial runs out.

I added a prediction results page to my Python football (Premier League soccer) prediction page.

A while ago I made a football predictor in Python to predict Premier League football results.

Original thread

The page would show predictions for the next 30 days of football matches and stay updated throughout the season. It uses a Gaussian Naive Bayes model to predict results based on past data. It uses the data from the 2021-2024 seasons.

Tonight I've added a page that shows how well the predictor has been performing over the season. It pulls the season's results from the BBC and compares its predictions to the results. You can see on the site the correct predictions in green and incorrect predictions in red.

Prediction results page: https://www.jimmyrustles.com/football/results

Original prediction page: https://www.jimmyrustles.com/football

Github repo: https://github.com/sgriffin53/footballpredictorflask

What My Project Does

The original project shows football predictions for the current season. This page shows how well the predictor is performing for the current season. It allows me to see which results were correct at a glance as it's colour coded.

Target Audience (e.g., Is it meant for production, just a toy project, etc.

This is mostly for me and my friend Jay, as we've been using it to bet on games (though its accuracy isn't great). The football prediction page gets about 10-15 human visitors a day, so

Handling embedded iframe player (PlayerJS - bunny.net) in Django template

I am trying to create a custom video player using PlayerJS within my Django app (Plain htmx template), have tested the general setup on a static website with no problem, but the player events/methods are not working properly in Django. Feel like I am missing something obvious.

The "ready" event fires on load

player.on("ready", () => {
console.log("Player ready");
})

But all other methods/events don't fire/ have no effect. The video shows normally and I can start/stop it using the player controls provided by bunny.net. However the "play" event is not firing. I am slo getting no error messages.

player.on("play", () => {
console.log("Video is playing");
})


Console

My template

{% extends 'base.html' %}
{% load customtags %}
{% block content %}

<h1>Videos index</h1>

My django based, open source PDF manager and viewer now supports editing and markdown notes

Hi r/django,

I am the developer of PdfDing. You can find the repo [here](https://github.com/mrmn2/PdfDing). Last time I posted about PdfDing, there were a couple of features that were requested quite often. As they are now implemented I just wanted to do a quick follow up post. PdfDing now has the following features:

* it is now possible to edit PDFs by adding annotations, highlighting and drawings
* you can organize your PDFs with multi-level tags as simple tags did not work for many people
* you can add markdown notes to store additional information about your PDFs
* there is now a live demo instance. You can try PdfDing [here](https://demo.pdfding.com) without pulling the docker image.
* very soon you will be able to star and archive PDFs

If you like PdfDing I would be really happy over a star on [GitHub](https://github.com/mrmn2/PdfDing). If anyone wants to contribute you are welcome to do so!

Django Developer Job at Spotter

Hi everyone! I recently applied for a Django Developer position at Spotte (Spotter Labs). After passing an initial screening, I was told to complete a coding assessment with the promise of a $100 USD reward upon successful completion.

Has anyone else done this task and actually moved forward in the process? Did you get paid and proceed to the next stage, or do you think this might be a scam? I know some might say "why not try," but I’m really stressed with my current work and don’t have the time to invest in this. If I end up spending time on it and nothing comes of it, that would be pretty disappointing.

Django APIs combined with iOS learning resources.

I've been learning Django and started building an iOS app as a first project. I followed a few iOS tutorials and used ChatGPT to get help whenever i get stuck.

I created a linter for your dependencies (requirements.txt file!)

Hey there. I've been working on a dependencies-related product for the last year. A lot of engineering teams that I've seen are building their own internal tooling to check on dependencies.

In short, people either update too frequently or don't update at all.

So, I decided to create a simple linter that checks all the main issues and best practices, comes with sensible defaults, and allows you to adjust it to your needs.

It supports npm/yarn, Go, pip, and Cargo. Any feedback is welcome!

Link: https://github.com/DepsHubHQ/depshub


What My Project Does
Checks your requirements.txt file on 20+ rules.

Target Audience
Mostly developers running it locally or on the CI. Still in beta.

Comparison
There are no popular linters for dependencies at all. The most popular tool to deal with dependencies is dependabot but it works in a completely different way.

Calling all drf repo owners - I'll do your work for you for free

Ok, slightly click-bait-ey title, but hear me out.


I'm a senior dev with over a decade of django experience, and nearly 2 decades working in AI. I have created a django specific AI to work as a mid level developer and I'd like to get some feedback on it's performance 'in the wild'.

The easiest way to do this at the moment is for me to manage it and to let it have a branch of it's own (so it's easy for you to optionally ignore anything it does). I use OpenAI and I'll cover all the costs. I'm happy to be effectively interviewed, share details of past projects (privately) etc., whatever processes you need to go through to validate this being worthwhile.

The repo can be open source or private, it can work with django, but it's not great at UI design, thus DRF, but I'm willing to try it on a django repo if there is appetite.

I use this in my current job, I'm head of department and thus able to make the call myself. I've also allowed friends to use it with their work and in general it's a positive experience - fire the request off, grab a drink and

Can you suggest correct model to make for given problem?

I am assigned with a task of adding a reward/penalty type function to our work site. its a point based system.

here is what the system already has.

Employees: Users

Tasks: employees/managers create and assign task, task detail, task deadline etc., you can mark task complete, amend deadline(if self assigned), update status (ongoing, pending, completed, on hold)



points function: points added if task marked complete before deadline, points removed if missed deadline. A manager can override points like negate penalty if there is a valid reason. managers can manually add or deduct points for other things like positive for finding bugs and negative for AWOL or submitting buggy code repeatedly etc. Task based points are calculated automatically while other types are assigned manually. Managers can override points awarded automatically given valid reason. eg: If -3 points are added for missing a deadline but the employee missed it due to being hospitalised then manager would just add/award +3 points to cancel it out. So all manually given points are called manual_adjustment_points.



so I am trying to make a model as the first step. But I keep feeling I am missing something. My current model is as following.



Model: Rewards:
