Question about store environment variables

I am trying to store secret environment variables. All the tutorials I have checked tell me to download python-datoenv and create a .env file. My file is called .flaskenv. Is that technically wrong? I followed Miguel's mega tutorial and he told me to call that file .flaskenv.

I made Versioneer work with Hatchling and pdm build backends

version-pioneer is a fork of Versioneer that supports Hatchling and pdm build backends.

The reason I hesitated for so long to switch from setuptools to hatchling etc. was Versioneer. I believe versioning system should be independent from the backend you use so you can easily migrate. Not only that you have to learn a new system, but also they don't work the same way. For example, I noticed other VCS versioning systems do not support dynamic version resolution in editable installs, which means while developing you will often get incorrect version.

### What My Project Does:

- Highly customisable: It's an easy-to-read script. Literally a simple Python script in which you can customise the version format or anything you need.
- 🐍 Runs with Python 3.8+
- ❌📦 No dependencies like package, config file etc. It runs with one Python file.
- ⭕ Works with any build backend with hooks. (Supports setuptools, hatchling, pdm)
- 🦀 Works with any language, not just Python.
- Version format "digits" generates digits-only version string which is useful for multi-language projects, Chrome Extension, etc. because their versioning standard is different.
- CLI makes it easy to compute the version without vendoring anything in the

HTTP queries parameters to MongoDB Query Language converter

I did develop a Python module for my company based on Regex to convert HTTP queries parameters sent from frontend app (React & Angular mainly) to our backend (FastAPI) in MongoDB Query Language (MQL). This way, frontend devs can easilly make specific queries without asking the backend devs.

It is working pretty well for a couple of years but it became pretty hard to maintain and update. I'm also asking myself, can I improve it ? Here is a couple of exemple that I've build over the years:

http://localhost:8000/api/v1/company?filter=category==507f1f77bcf86cd799439011^createdat=BETWEEN(2024-01-01,2025-06-30)^nbemployee>10

# Output in Python
from query import MongoQueryManager as mqm

query = mqm(filter="category==507f1f77bcf86cd799439011^createdat=BETWEEN(2024-01-01,2025-06-30)^nbemployee>10", page=0, limit=100, orderdir="asd", orderby="createdat", excludedkeys=)
print(query.mongoargs)

{'filter': {'$and': [{'category': '507f1f77bcf86cd799439011'}, {'createdat': {'$gte': 1704063600.0, '$lte': 1751234400.0}}, {'nbemployee': {'$gt': 10}}]}, 'sort': [('createdat', -1)], 'skip': 0}

Note : 507f1f77bcf86cd799439011 is an ObjectId (specific to MongoDB).

There is some limitation, we can only put 3 logical operator if there is AND and OR at the same time. Example : arg1=1 AND arg2=2 AND arg3=3 OR arg4=4. I never find a way to code something stable

SQLalchemy is driving me nuts

I want to set all timestamps in DB with timezone utc, but my DB uses its own local time as timezone instead. Can anyone spot what I am doing wrong?

My sqlalchemy defs looks like this.

import sqlalchemy as sa
import sqlalchemy.orm as so
from datetime import datetime, timezone

timestamp: so.Mapped[datetime] = so.mapped_column(sa.DateTime(timezone=True), default=lambda: datetime.now(timezone.utc))

When I pull the data from the DB I get something like this, where timezone seems to be the server timezone:

datetime.datetime(2025, 2, 9, 23, 33, 59, 666407, tzinfo=datetime.timezone(datetime.timedelta(seconds=3600)))

While I would want something like this:

datetime.datetime(2025, 2, 10, 12, 31, 56, 422389, tzinfo=datetime.timezone.utc)

A Modern Python Repository Template with UV and Just

Hey folks, I wanted to share a Python repository template I've been using recently. It's not trying to be the ultimate solution, but rather a setup that works well for my needs and might be useful for others.

What My Project Does

It's a repository template that combines several modern Python tools, with a focus on speed and developer experience:

\- UV for package management

\- Just as a command runner

\- Ruff for linting and formatting

\- Mypy for type checking

\- Docker support with a multi-stage build

\- GitHub Actions CI/CD setup

The main goal was to create a clean starting point that's both fast and maintainable.

Target Audience

This template is meant for developers who want a production-ready setup but don't need all the bells and whistles of larger templates.

Comparison

The main difference from other templates is the use of Just instead of Make as the command runner. While this means an extra installation step, Just offers several advantages, such as a cleaner syntax, better dependency handling and others.

I also chose UV over pip for package management, but at this point I don't consider this as something unusual in the Python ecosystem.

You can find the template here: https://github.com/GiovanniGiacometti/python-repo-template

Happy to hear your thoughts and suggestions for improvement!

Dynamic Templates help

Hello everyone.

I'm working on a project but I'm stuck in a part and I'm unsure on how to proceed on it.

I have a screen on my website where you're supposed to select an object, a Date based on said object and choose which action to take on that object and date.

I'd like to make it in such way that, if the user selects a Date from object A, that Actions appear or disappear based on whenever or not that object at that date has already done that action (it appears whenever A on Jan 09 has already done said action or not).

I already have a system by which I determine whenever that object has gone through that action at certain dates (just does an AND to a predetermined value), but I can't figure out how to change the actions list so that whenever the user chooses a Date on it , it swaps the value of A at that date and changes what values it should display.

If you could give me any suggestions I'd greatly appreciate it.

Thanks!

How do you self learn to make production ready applications

Hi all,

I am a software engineer with around 2.7 years of experience. I had to work on a non technical repetitive task for like a year and the rest of the time I was either working on a project making small changes or I was on the bench.

I recently got into Django and my question is how do people self learn. Let's say I watch a tutorial but I'm always stuck when I start to make a self project. Without the guidance of someone how do I know what are the best practices. Also when working on a client project one has access to paid services that they need to integrate. How do I get the same learning curve while working on personal projects?

I would really appreciate some tips from people who self learned the django on how they approach a project. Or any suggestions on becoming a good programmer even if they're not related to Django. Please be kind 🙏

Tldr: I guess what I'm looking for is how do people who self learn become pro in a language and how do they keep themselves up to dated.

Inherit from "dict" or "UserDict"?

I'm working on a project where we need to integrate a dictionary with a ttk.Treeview. The easiest approach would have been to handle data and visualization separately, but due to project requirements, we opted for a combined structure where both are tightly linked.

The idea is straightforward in theory: any change to the dictionary should be reflected in the Treeview, and any modification in the Treeview should update the dictionary. To achieve this, we're implementing the most efficient communication path between the data structure and its visualization within a single class.

Our initial plan was to intercept accesses using __getitem__, __setitem__, and __delitem__ by inheriting directly from "dict". However, a teammate suggested we should use "UserDict" from "collections" instead. We did a quick switch with the little code we have so far, and in practice, both approaches seem to work exactly the same.

That said, how can we be sure which one is the better choice for extending dictionary functionality?

This has sparked some minor disagreements in our team. ChatGPT leans towards "UserDict", but some of us prefer minimizing intermediaries to ensure efficiency stays "bare-metal," if you know what I mean.

The Hidden Bias of Alembic and Django Migrations (and when to consider alternatives)

Hey all,

My name is Rotem, I'm one of the creators of [Atlas](https://atlasgo.io), a database schema-as-code tool. You can find us on [GitHub](https://github.com/ariga/atlas).

I recently wrote a blog post covering cases where you might want to consider an alternative to Alembic or Django migrations for your schema changes.

Don't get me wrong - alembic and Django migrations are great tools - among the best in the industry - if you are using them successfully, you should probably keep at it :-)

However, over the years, I've come to realize that these tools, having been built to fit the use case of serving an ORM, have biases that might hinder your project.

In case you are interested, you can [find the blog post here](https://atlasgo.io/blog/2025/02/10/the-hidden-bias-alembic-django-migrations?utm_source=reddit&utm_medium=post&utm_campaign=python).

Atlas has two capabilities that enable it to work very well inside ORM codebases, `external_schema` and `composite_schema`. Atlas has ORM integration plugins called "providers" that allow it to read the desired schema of the database from your ORM code, you can then use it like:

data "external_schema" "sqlalchemy" {
program = [
"atlas-provider-sqlalchemy",

Someone talk me down from using Yamale

...or push me over the edge; whichever. So I've been looking into YAML schema validators that can handle complex yaml files like, for example, the `ci.yml` file that configures GitHub actions.

The combined internet wisdom from searching google and conferring with Gemini and Claude 3.5 is to use `jsonschema.validate`. But that seems, IDK, like just wrong to the core. Besides aren't there a few things that you can do in .yml files that you can't in .json?

After some scrolling, I came across Yamale, which looks pretty awesome albeit underrated. I like the `includes` and 'recursions', but I have a few things about it that make me hesitate:
\- Is a really as popular as PyPy makes it seem (2M monthly dowloads)? When I search specifically for use cases and questions about it on SO, 🦗. Same here on Reddit. Maybe everyone using it is so happy and it works so well as to be invisible. Or maybe that "2M monthly downloads" means nothing?
\- Is it going to be around and supported much longer? From the GH repo

Boolean search query generator

I’m working on a project where I generate Boolean queries using an LLM (like ChatGPT), but I need to ensure that the generated queries are valid based on the data in my database. If certain terms in the query don’t exist in the database, I need to automatically remove or modify them.

For example:

LLM-Generated Query: ("iPhone 14" OR "Samsung Galaxy S22") AND ("128GB" OR "256GB") AND ("Red" OR "Blue")

Database Check:

My DB has entries for "iPhone 14" and "Samsung Galaxy S22".

It only has "128GB" as a storage option (no "256GB").

For colors, only "Red" is available (no "Blue").


Modified Query (after DB validation): ("iPhone 14" OR "Samsung Galaxy S22") AND "128GB" AND "Red"


How to efficiently verify and modify these Boolean queries based on the DB contents? Are there existing libraries or tools that could help streamline this process?

Keep in mind that I can only use one llm cal for this purpose.
