Have started the django doc again, and got stuck.

At this part of "Writing your first app", I try to type in "py manage.py startapp polls" and it shows "ModuleNotFoundError: No module named 'polls". Why is that?

🚀 Feature Friday: PostgreSQL Connection Pools!

Welcome to this week's Django Feature Friday on PostgreSQL Connection Pools!

This small-but-mighty change lets you enable connection pooling with a single line in your settings. This reduces the overhead of accessing your database, leading to improved performance.

You can turn it on like this:

DATABASES = {
"default": {
"ENGINE": "django.db.backends.postgresql",
# ...
"OPTIONS": {
"pool": True,
},
},
}

If you want fine-grained control over your connection pools, you can also explicitly configure them by passing in a dictionary of settings:

DATABASES = {
"default": {
"ENGINE": "django.db.backends.postgresql",
# ...

P Analysis of why UMAP is so fast

Hi, I recently spent some time to understand the core implementation of the UMAP algorithm from the point of view how it was implemented and why it's so fast (even though it's in python). I decided to decompose the algorithm into smaller steps in which I add some minor improvements to the code (one by one), so that at the end the final results are very similar to what I can get from the UMAP.

To my surprise, most of these changes were just tricks in the optimization code to run things faster or update less important things less often. Of course, my implementation does not reproduce the UMAP algorithm in 100% as it was done in the educational purposes.

I provided a detailed explanation in my project of what I had to add in each step to move towards UMAP like algorithm. Here is the project page: https://github.com/kmkolasinski/nano-umap

If you are a person like, who likes to optimize the code for performance you may find this interesting. Here is a demo what I was able to get:

TLDR: in UMAP they:

use ANN library to quickly find top k-NN,
use good initialization method which makes things more stable and algorithm requires

fxgui: Collection of Python Classes and Utilities designed for Building Qt-based UIs in VFX

Hey Python enthusiasts! Any VFX folks here? I've developed a little package called `fxgui` \- a collection of Python classes and utilities designed for building Qt-based UIs in VFX-focused DCC applications.

It's available on [GitHub](https://github.com/healkeiser/fxgui), [PyPI](https://pypi.org/project/fxgui), and comes with [documentation](https://healkeiser.github.io/fxgui). I'd love to hear your thoughts and get some feedback!

# Target Audience

* VFX/CGI people working from multiple DCCs.

# Key Features

* Quick setup of common widgets.
* Reusable custom UI components.
* Fully compatible over PySide2/PySide6, thanks to [qtpy](https://pypi.org/project/QtPy/).

# Comparison

* Specifically designed for multi-DCC environments (Maya, Houdini, Nuke, etc.).
* Saves development time by offering ready-to-use components.
* Maintains consistency and standardization across projects and DCCs.

Unable to Login with Flask-WTF and Flask-Login

\---

**Denoscription:**

I'm building a Flask application with user login functionality using Flask-WTF for form handling and Flask-Login for user authentication. However, I am unable to log in successfully. The page does not redirect as expected, and the login validation does not work.

I have implemented CSRF protection, and I believe the issue might be with how the data is being validated or how the routes are configured.

\---

**What I've Tried:**

1. Ensured that I am redirecting using \`url\_for()\` to a valid route.
2. Added \`csrf.init\_app(app)\` in my \`create\_app()\` function.
3. Included \`{{ form.csrf\_token() }}\` in my login form.
4. Verified that my database connection works, and user data is stored correctly.
5. Checked that Flask-Login's \`login\_user()\` function is being called.

Custom Analytics Libraries

I've made a very basic Django site, I'll deploy it later on but I'm actually having a little of fun making it. I work as an analyst and I've managed to get 4 queries from and display them with chart.js and I'm super happy with how it looks, I'll do some more formatting at a later date but I'd like to keep building this out.

Does anyone else have any experience making their own analytics stuff? What libraries look good for displaying charts and stuff? I realize I'm not reinventing the wheel, we use Looker and Tableau at work but I would like to do something cool.

Finally Completed : A Personal Project built over the weekend(s) - Netflix Subnoscript Translator

Motivation : Last week, I posted about my project, Netfly: The Netflix Translator, here on r/python. I initially built it to solve a problem I ran into while traveling. Let me explain :

On a flight from New Delhi to Tokyo, I started watching an anime movie, The Concierge. The in-flight entertainment had English subnoscripts, and I was hooked, but I couldn’t finish it. Later, I found the movie on Netflix Japan, but it was only available with Japanese subnoscripts.

Here’s the problem: I don’t know enough Japanese (Nihongo wa sukoshi desu) to follow along, so I decided to build something that could fetch those Japanese subnoscripts, translate them into English, and overlay the translation on the video while retaining the Japanese subnoscripts which would give me better context.

What started as a personal project quickly became an obsession.

What does the Project Do ? : The primary goal of this project is simple: convert Japanese subnoscripts on Netflix into English subnoscripts in an automated way. This is particularly useful when English subnoscripts aren’t available for a noscript.

The Evolution of this Project / High Level Tech Solution : This is not the first iteration of Netfly. It has gone through two major updates based

My site passes 45 security checks..

I made an ecommerce site with django, I am not that expert on security.. I try to follow what django provides for that, and I do drf’s is_valid method to incoming data..

There are about 150 apis and 50 frontend pages. I asked the cyber security agency that the government operates..

They check about 45 cyber attacks include OWASP top10.. it took about 2weeks and I got the report.. I was very nervous because I spent 2years to build the site and if it had many vernerabilities.. I wouldnt know how to fix..

Wow.. no single vernerabilies found, thanks to django.. I cant believe that django is that solid and secure..

Write good tests

I just published an article outlining what I think good tests in Python are often missing. It's not intended to flesh out on any of the topics, and is frugal on the details where I think they are better explained other place. Rather it's intended to inspire your style guides and convention documents. These are an assembly of issues that's been up for discussion in various places I've worked, and my opinionated take on them.

So please, write good tests.

What is the industry standard for Django project structure?

tldr: I have seen many posts on what the "best" Django project structure is. What is standard in the industry and why?

I'm learning the Django framework and I'm trying to investigate and understand the project folder structure and reasoning behind it. I'm aware of clean architecture and vertical slice architecture, so my first instinct is to adapt to something like that. I came across https://www.jamesbeith.co.uk/blog/how-to-structure-django-projects/ , which seems in line with what I'm looking for, though I'm not sure how often it is used in practice.

From Googling, it seems that a typical structure is the following, https://github.com/HackSoftware/Django-Styleguide-Example/ , where basically every module is a Django app (e.g. api, core, emails, users, etc are apps). To me, this seems to have some "disadvantages".

1. Models and migrations are scattered throughout the project, as opposed to being in 2 folders.
2. Excess boilerplate
3. Not everything needs to be a Django app (e.g. utility functions which don't reference Django at all).

From my current understanding, it seems like the only reasons we need Django apps are the migrations folder and models.py, as well a way to provide url patterns (e.g. urls.py) and views (e.g. views.py) so that the include function can pick them up. Unless I'm
