Is using if TYPE_CHECKING: to type the objects manager a good practice?

Hey everyone,

To get my linter and IDE (free PyCharm) to recognize the type of the default objects manager, I'm using this pattern:

# models.py
from typing import TYPE_CHECKING
from django.db import models  

if TYPE_CHECKING:
    from django.db.models.manager import Manager
        
class MyModel(models.Model):
    # ... fields ...

    # is this ok?
    if TYPE_CHECKING:
        objects: Manager["MyModel"]

This works and solves the "unresolved attribute" warnings.

Is this a good, standard practice, or is it considered a hack? I know PyCharm Pro handles this, but as a poor/greedy programmer, I'm looking for a free solution. 😅

Thanks!

Django statics won't work for admin & drf

Workign on updating my django 4.x to 5.x. I noticed that statics for django admin & drf weren't working.

Solution: Disabled (comment out) django debug toolbar from installed apps and middleware section in settings.py. FYI, I have a local docker compose serving minio s3.

STATICFILES_DIRS = [
os.path.join(BASE_DIR, "static"),
os.path.join(BASE_DIR, "media"),
]

# Static files
STATIC_URL = f"{STATIC_URL_BUCKET}/static/" # Or use your public MinIO endpoint

# Media files (user uploads)
MEDIA_URL = "/media/" # Not used for direct serving, but required by Django

Website version of Christopher Manson's 1985 puzzle book, "Maze"

This out of print book was from before my time, but Maze: Solve the World's Most Challenging Puzzle by Christopher Manson was a sort of choose-your-own-adventure book that had a $10,000 prize for whoever solved it first. (No one did; the prize was eventually split up among twelve people who got the closest.)

I created a modern, mobile-friendly web version of the book.

GitHub (with Python source): https://github.com/asweigart/mazewebsite

Website: https://inventwithpython.com/mazewebsite/

Start of the maze: https://inventwithpython.com/mazewebsite/directions.html

There are 45 "rooms" in the maze. I created HTML image maps and gathered the text descriptions into a throwaway Python script that generates the html files for the maze. I didn't want it to rely on a database or backend, just HTML, CSS, and a little Bootstrap to make it mobile-friendly. The Python code is in the git repo.

## What My Project Does

Generates HTML files for a web version of Christopher Manson's 1985 puzzle book, "Maze"

## Target Audience

Anyone can view the output website. The Python code may be of interest to people who have similar one-off projects.

## Comparison

The throwaway script spits out html files, making it easy for me to make updates to all 45 pages at once. It's a one-off project that doesn't use other modules, so it's

I can't seem to get the flask app with blueprints. Does anyone know how to fix this?

I have a flask app structured similar to this https://github.com/miguelgrinberg/microblog.

Also instead of microblog.py I just called the file run.py

Here is my file-path in the app in powershell.

(my_env) PS C:\\Users\\user\\Downloads\\myapp



The first picture is myapp folder and files within them.

The second picture is app folder and files within them though I removed some names because I am working on an original idea

Also am I correct folder and Should I setup my flask app like https://github.com/miguelgrinberg/microblog ?





Here is myapp/config.py.

Here is my init.py folder in the app folder.

Here is models.py

myapp/run.py

```py

from app import create_app

app = create_app()

```









Here is what I am using to run the flask app

```

$env:FLASK_DEBUG=1

(some_env) PS C:\\Users\\user\\Downloads\\myapp> $env:FLASK_ENV='dev'

(some_env) PS C:\\Users\\user\\Downloads\\myapp> $env:FLASK_DEBUG=1

(some_env) PS C:\\Users\\user\\Downloads\\myapp> $env:FLASK_APP = "run.py"

(some_env) PS C:\\Users\\user\\Downloads\\myapp> flask run

```



Here is the error and output after I run `flask run`

Usage: flask run [OPTIONS\]

Try 'flask run --help' for help.

SQLAlchemy just the core - but improved - for no-ORM folks

Project: https://github.com/sayanarijit/sqla-fancy-core

What my project does:

There are plenty of ORMs to choose from in Python world, but not many sql query makers for folks who prefer to stay close to the original SQL syntax, without sacrificing security and code readability. The closest, most mature and most flexible query maker you can find is SQLAlchemy core.

But the syntax of defining tables and making queries has a lot of scope for improvement. For example, the table.c.column syntax is too dynamic, unreadable, and probably has performance impact too. It also doesn’t play along with static type checkers and linting tools.

So here I present one attempt at getting the best out of SQLAlchemy core by changing the way we define tables.

The table factory class it exposes, helps define tables in a way that eliminates the above drawbacks. Moreover, you can subclass it to add your preferred global defaults for columns (e.g. not null as default). Or specify custom column types with consistent naming (e.g. created_at).

Target audience:

Production. For folks who prefer query maker over ORM.

Comparison with other projects:

Piccolo: Tight integration with drivers. Very opinionated. Not as flexible or mature as sqlalchemy core.

Pypika: Doesn’t prevent sql injection by default. Hence can be considered insecure.

Raw queries as strings

Pypp: A Python to C++ transpiler WIP. Gauging interest and open to advice.

I am trying to gauge interest in this project, and I am also open to any advice people want to give. Here is the project github: https://github.com/curtispuetz/pypp

# Pypp (a Python to C++ transpiler)

This project is a work-in-progress. Below you will find sections: The goal, The idea (What My Project Does), How is this possible?, The inspiration (Target Audience), Why not cython, pypy, or Nuitka? (Comparison), and What works today?

## The goal

The primary goal of this project is to make the end-product of your Python projects execute faster.

## What My Project Does

The idea is to transpile your Python project into a C++ cmake project, which can be built and executed much faster, as C/C++ is the fastest high-level language of today.

You will be able to run your code either with the Python interpreter, or by transpiling it to C++ and then building it with cmake. The steps will be something like this:

1. install pypp

2. setup your project with cmd: `pypp init`

3. install any dependencies you want with cmd: `pypp install [name\]` (e.g. pypp install numpy)

4. run your code with the python interpreter with cmd: `python my_file.py`

5. transpile your code to C++ with cmd: `pypp transpile`

6. build the C++ code with

How do you guys secure your django websites?

recently i was working on a freelance project
i wrote a small function for deleting objects but each time i notice that there's something wrong and it was the lack if security and its driving me crazy that each time i have to implement a new security function


so my question is:

How do you guys implement the security features?

do you create all of the security features at once? or wait the production and user feedback?

[Project] I built an open-source tool to turn handwriting into a font using PyTorch and OpenCV.

I'm excited to share HandFonted, a project I built that uses a Python-powered backend to convert a photo of handwriting into an installable .ttf font file.

**Live Demo:** [https://handfonted.xyz](https://www.google.com/url?sa=E&q=https%3A%2F%2Fhandfonted.xyz)
**GitHub Repo:** [https://github.com/reshamgaire/HandFonted](https://github.com/reshamgaire/HandFonted)

**What My Project Does**

HandFonted is a web application that allows a user to upload a single image of their handwritten alphabet. The backend processes this image, isolates each character, identifies it using a machine learning model, and then generates a fully functional font file (.ttf) that the user can download and install on their computer.

**Target Audience**

This is primarily a portfolio project to demonstrate a full-stack application combining computer vision, ML, and web development. It's meant for:

* **Developers and students** to explore how these different technologies can be integrated.
* **Hobbyists and creatives** who want a fun, free tool to create a personal font without the complexity of professional software.

**How it Differs from Alternatives**

While there are commercial services like Calligraphr, HandFonted differs in a few key ways:

* **No Template Required:** You can write on any plain piece of paper, whereas many alternatives require you to print and fill out a specific template.
* **Fully Free & Open-Source:** There are no premium features or sign-ups. The entire codebase is available on GitHub for anyone to inspect, use, or learn from.
* **AI-Powered Recognition:** It

Django Channels

Hi so i need to implement notifications in my application and I have a few questions about Django channel layer(COuld really use some help here):



1. Does every consumer instance get its own channel layer name ? ( lets say i have 2 websocket URLs mapped to 2 consumers , and every client establishes a connection to both these consumers via the url router )



2. Is the channel layer name uniquely generated only for that specific connection ? and therefore might be different if the same consumer spins up another instance of itself for a connection ?



3. How do i store and access these channel layer names for each user when i need to add them to a group or something . Do i just store them in a database for the duration of the connection and get rid of them after ?
