How would you handle this model? Room with multiple beds but limit how many people can be assigned to room based to total beds.

I am creating an application to manage a barracks room. However, some rooms have 2 - 3 beds inside the 1 room. If I want to assign an occupant to each room, would it be best to create more than 1 room with the same room number? Currently I have it set so one room shows Bed Count, in hopes I could limit how many people can be assigned to a room. Now I am thinking of creating more than 1 room to total the number of beds.

​

Currently,

Room 123A has 3 beds.
In the DB I have 1 123A with a bed count of 3.

Thinking:

Room 123A has 3 beds
In the DB create 123A x 3.

I was curious how django keeps track of all my model classes...

Ever wondered what happens under the hood when you run python manage.py makemigrations in Django? I recently asked this to myself and went through the rabbit hole of reading the Django code base.

I wrote a short blog post with a short deep dive into the model detection mechanism. No magic wands, just a bit of metaclasses, the new method, and a dash of django.setup().

sqlglot - Amazing SQL parsing library

Wanted to give sqlglot a shoutout as it saved me a ton of time.

I had a task that involved building a dependency graph by statically analyzing the relationship of MySQL views. Initially, I was using sqlparse to extract the dependencies from the SQL statements, but it required me to create an increasingly hacky recursive function. I kept encountering examples in our codebase that required more test cases and further updating.

Then I stumbled upon sqlglot, and the code reduced to just a few lines, working immediately. It was barely more complex than this:

from sqlglot import parseone, exp

for table in parseone(sqlstatement).findall(exp.Table):
print(table.name)

I'm surprised I hadn't heard of it before.

Pytest over Unittest

Hi all ,

I'd like to hear your opinions over when you have decided to use Pytest over Unittest as your testing framework for your projects and why.

I've personally never used Pytest but recently found it on a project I started to work on and I've been finding it interesting.

Introducing Great Tables

Great Tables is a *great* new Python package that simplifies the process of making tabular data presentable for any sort of publication task. With Great Tables, you can easily use data from a Pandas or Polars DataFrame and turn it into a beautiful table that can be included in a notebook, a Quarto document, or exported as HTML.


We've been working hard on making this package as useful as possible, and we're excited to share it with you. The package (v0.1.0) is available on PyPI and can be installed with:


pip install great_tables


The documentation site at https://posit-dev.github.io/great-tables/articles/intro.html has a *Get Started* tutorial that will walk you through the basics of using the package. The API documentation is also available on the site and it is chock full of examples that'll show you how to use the various features of the package.


We want Great Tables to be really useful for your work and so we really value any and all feedback. Send us a note in https://github.com/posit-dev/great-tables/issues or https://github.com/posit-dev/great-tables/discussions anytime you like!

Can python/ipython be used to replace Bash?

I am a heavy Bash user, and curiosity has me trying to see if it's feasible to move completely to Python.

chsh -s $(which ipython3)
exec ipython3

I'm just taking my first baby steps, but how much can I expect it to act like a normal shell like in /etc/shells?

(I did manually add ipython3 there, but unsure if that did anything.)

Since .bashrc is no longer being read, I probably need a .ipythonrc or something, to setup my environment, but I don't know how to make sure it's read when a new terminal opens. Is there a Python equivalent to /etc/profile, /etc/rc.local etc... ?

If I try to put !ipython3 --profile=pagefault into ~/.ipython/profile_default/startup/startup_default.py I get:

TerminalIPythonApp WARNING | Unknown error in handling startup files:
File ~/.ipython/profiledefault/startup/startuppagefault.py:6
!ipython3 --profile pagefault
^
SyntaxError: invalid syntax

What is the proper way to ensure my custom profile gets loaded by default?

Finally, I'm having a lot of trouble with my custom layout. Would some of you mind helping me cheat my way through by sharing your custom ipython_config.py scripts?

Deciding which functions/routes should be async

I have an application powered by FastAPI with HTTP routes that call different internal functions, celery tasks, 3rd party APIs, and DB queries.

How should I decide what should be async? Also how should i manage the different normal/async functions? For example, I'm using Pymongo & Motor, should I make seperate classes for each?

lockfiles for hatch projects

I'm a huge fan of using hatch to manage my Python projects. It lets me define my projects with a single pyproject.toml file and define my extra environments and scripts (i.e testing / linting / docs). One big thing it's missing though is an integration with lockfiles.

For all my projects I found myself regenerating manual lock files using complex shell commands with pip-compile to get a reproducible environments across devices using a custom pre-install-command. I finally decided that instead of hacking together the same solution on all my projects I would build a plugin that handles this complexity for me.

I came up with hatch-pip-compile \- it's a hatch plugin that connects your hatch-managed virtual environment to a lockfile managed with pip-compile. The plugin detects whether your environment or lockfile is out to date and automatically syncs them when needed - and it's fast!

It's completely configurable and easy to get started. After adding the last few features and settling on a stable configuration I finally feel like it's ready for a wider audience. I'm extremely proud of how it turned out and I'm excited to share it with the hatch-world. I hope you find it useful for your Python projects!

Simple and easy documentation Builder

Hello redditors,

I've been working on an open-source project called BrowseDocs, designed to assist open-source developers in documenting their libraries and tools with greater intuitiveness. The goal is to provide developers with an integrated and enhanced user experience while reading documentation.

​

Some of the current features include:

Generate documentation pages from markdown files (chose .md because most of the developers are familiar).
Create multi-version, multi-paged documentation with a click of button.
dark/light themes included by default.
A quick search. (currently just a simple search)
A separate about page for every project.
Rich text editor for developers to write blogs and tutorials.

Now the project itself is in its first iteration, which is why I look forward for your feedback. I'd like to know what features you'd like to see in the upcoming releases and what features you'd like to be removed from the project. I look forward to your responses.

PS: I am still working on enhancing the UI of the landing page, any heads up would be greatly appreciated

​

You can visit the project at https://browsedocs.com

Github repo for the project: https://github.com/PaulleDemon/BrowseDocs

​

Thanks,

Have a great day ahead.
