Static site to Django templates
So I am trying to learn more templating by turning a static site into a Django site with generic views. Is this a good approach or should I start from scratch? I am doing it because I am trying to learn about templating and though it would be cool to see how easy it would be to turn this static site into something I can use Django models and DB with.

Django e-commerce hosting
Hi all!
Context:
I created my first e-commerce with Django, right now I am hosting it with render ( free tier) and the project uses SQLite. The problem right now is that the free tier does not hold the project on all the time, after 10-15 minutes of inactivity it goes idle and takes around 1 minute to become active again, when it becomes active again all the new products that were added through admin panel (while the website was live ) disappear , as they were never there and I understand the reason.
Questions : if I upgrade to the standard tier ( the one that cost 7-9euro /month ) would that solve the problem with the new added products?( as the app won’t have downtime)
Do I have to purchase from render the postgreSQL as well? ( but then it becomes a bit costly with the standard version as well ( total of 14 euro or something like this)
Extra: I am using Cloudinary for the images uploaded via admin panel.
Or if someone knows better cost-eficient option for hosting or some workarounds that may work I would very much appreciate!
Thank you!

migrate many-to-one models
I tried to create a many-to-one relationship in my model, but when I migrated the model, I encountered an error.

i create two class in the names category and product and they are very simple but i don't know that should use specific properties for ForeignKey fild or no . Does anyone know how to properly define models with a ForeignKey? Also, if I want to delete some migration files, can I remove them manually, or must I use the terminal?"

Speeding up api request.
Hi everyone.
For the last 8 months or so (lost track abit!) I’ve been building a meal planning platform, but what I haven’t been able to speed up is the response of my backends api
The stack is nuxt3, drf, Postgres, nginx in a docker compose digitaloceon droplet. I have tampered with putting the highest of specs on the droplet and it doesn’t have any notable effects
The part I’m struggling with is when you browse recipes, they take ages (2-4seconds). I’m loading 12 a time, with a fair bit of information being sent but limited as much as I can. It’s only sending thumbnail size images condensed. I have redis but as each request is quite unique I’m unsure how to use it here.
If anyone’s experienced this it would be fantastic to hear your experiences!

Really hope this doesn’t come across as shilling

Wi-Fi Controlled Robot Using Python
* **What My Project Does**
I've built a robot that can be controlled via Wifi and has a camera feed so you can see where you are going. The big idea is to have this autominusly controlled by a computer that can use computer vision to analyse the camera feed, so that it can retrieve the trash cans.
This fist iteration is just to get it controlled over WiFi. The robot has Raspberry Pi Zero on it which handles the camera feed and exposes it via a web server and a Raspberry Pi Pico which has a webserver and can contol the servo motors. There is a basic API on the Pico to allow for commands to be sent to it.
I have another Pi with a Python simple server which displays a page which combines the camera feed and the controls of the robot.
I realise I could have done this all on one Pi!

I built xlwings Lite as an alternative to Python in Excel
Hi all! I've previously written about why I wasn't a big fan of Microsoft's "Python in Excel" solution for using Python with Excel, see the [Reddit discussion](https://www.reddit.com/r/Python/comments/1de2hkw/my_thoughts_on_python_in_excel). Instead of just complaining, I have now published the "xlwings Lite" add-in, which you can install for free for both personal and commercial use via [Excel's add-in store](https://appsource.microsoft.com/en-us/product/office/wa200008175?tab=overview). I have made a [video walkthrough](https://youtu.be/amCCEbJ39W8?si=3vmVEZUr6RA0-IgS), or you can check out the [documentation](https://lite.xlwings.org/).
xlwings Lite allows analysts, engineers, and other advanced Excel users to program their custom functions ("UDFs") and automation scripts ("macros") in Python instead of VBA. Unlike the classic [open-source xlwings](https://github.com/xlwings/xlwings), it does not require a local Python installation and stores the Python code inside Excel for easy distribution. So the only requirement is to have the xlwings Lite add-in installed.
So what are the main differences from Microsoft's Python in Excel (PiE) solution?
* PiE runs in the cloud, xlwings Lite runs locally (via Pyodide/WebAssembly), respecting your privacy
* PiE has no access to the excel object model, xlwings Lite does have access, allowing you to insert new sheets, format data as an Excel table, set the color of a cell, etc.
* PiE turns Excel cells into Jupyter notebook cells and introduces a left to right and top to bottom

Building a car service website
Hey everyone,
I’m building a Django app for a car booking service, and I’m trying to design a clean reservation + payment flow that’s flexible and user-friendly.
What I have:
• A Reservation model that holds all key info (vehicle, route, customer, pricing, status, etc.)
• A Rate model that links a vehicle and route (each with one-way and round-trip prices)
• When a user browses the site, they see route/vehicle combinations with prices
What I want to build:
• When a user clicks “Book Now” next to a specific rate (say, SUV from Airport to Hotel):
• They’re taken to a pre-filled reservation form with that vehicle and rate
• They fill in customer info, passenger count, special requests, flight info, etc.
• After submitting, they choose to either:
• Pay now via Stripe
• Save their card and pay later
I’m not using Stripe Checkout directly. Everything is tied to the Reservation object first, and then payment is triggered.
What I’m stuck on:
• What’s the best pattern for pre-filling the reservation form with a specific rate? I did a request.GET.get(‘vehicle_type’) and same for route and rate to get this information but i feel theres a better way
Is there a good way to cleanly separate form logic from payment logic without overcomplicating views?
How should I handle the “save card for later”

Created my first COPYWRITING TOOL software with the help of Flask
Hey everyone,
A project I've been working on for the past 7 months is the following: Geniusgate.ai V1
It's an AI-powered copywriting tool, and it's been something I've been working on for a while.
I'd figure it would be pretty cool to show everyone here as it's my first SaaS.
Honestly, as I've made it temporarily free for 7 days. If you do decide to try it out, please let me know what you do and do not like, as I am trying to get as much feedback as possible. I'll be making adjustments to the first version within a few months as I gather feedback.

We made this with the following:
React, Next.js, and Flask.
One of the biggest obstacles was that I had to differentiate it from regular GPT, as you may know, ChatGPT can do some form of copywriting. To overcome that problem, I had this tool run on GPT, but it was trained by countless professional copywriters with multiple successful high-converting copy input examples.
The other issue was that initially, we had the website designed with React, such as the landing page, and each blog post was manually added.

The code that I currently have in my Procfile is web: gunicorn app:app - yes, gunicorn is installed, yes it's in the requirements and no it's not saved a a .txt.
the error code that I keep getting is heroku ps:scale web=1

there is also a venv folder, static, src, data and reports folder saved within the root directory.

Trying a Spring Boot style project structure in Django
I've been working with Django for the last 3–4 years. One thing I’ve always struggled with is keeping things clean and modular as the project grows.
Django’s flexibility is great, but I’ve often found myself mixing business logic in views, duplicating structure across apps, and losing track of where certain responsibilities live. So I’ve been trying a new approach lately borrowing ideas from Spring Boot (Java), which I used briefly and really liked for its structure.
What I tried:
Created a /apps/ directory where each app is treated as a self-contained module
Split responsibilities into:
controllers/ → class-based views
services/ → business logic
dtos/ → Pydantic v2 for request/response validation
Added a few management commands to generate apps + CRUD automatically:
python manage.py generateapp blog
python manage.py generatecrud blog Post
The goal is to keep things clean and explicit, especially for larger projects or when working with a team.
Here is the Repo Link 🖇️
It’s not trying to be a full framework, just a structured way to get up and running faster with good practices baked in. Eventual goal is to teach Django in meaningful way
Would love your thoughts on:
Is this too much structure for Django?
Does separating logic this way actually help in the long run?
What would you improve if

docdog: open source generating docs using claude
Hi everyone, gonna just go straight to the point.
What my project does: Creates docs for you by chunking then summarising it. Remember to set up your own api key and put it in a .env file.
Target audience: anyone
Why did I do it? sometimes i write all my code and then i forget what i was writing a day ago. and then i have to relook at my codebase all over again ..
Comparison: claude itself?
How to use Docdog: Just run pip install docdog then run docdog
Future enhancements: May add new features like more models etc.
Note: This is NOT a tool to replace writing docs. Ultimately you should still write your own docs but this will help you to save some time.
Link: https://github.com/duriantaco/docdog
For any bug or feature please raise an issue in my github page. Please leave a star if you found it useful. If you didn't find it useful, having a bad day, had a breakup or whatever, you can use this post as a punching bag. Thats all. Thanks

PEP 751 (a standardized lockfile for Python) is accepted!
https://peps.python.org/pep-0751/
https://discuss.python.org/t/pep-751-one-last-time/77293/150
After multiple years of work (and many hundreds of posts on the Python discuss forum), the proposal to add a standard for a lockfile format has been accepted!
Maintainers for pretty much all of the packaging workflow tools were involved in the discussions and as far as I can tell, they are all planning on adding support for the format as either their primary format (replacing things like poetry.lock or uv.lock) or at least as a supported export format.
This should allow a much nicer deployment experience than relying on a variety of requirements.txt files.

django-components v0.135 - Defaults, Vue-like class and style attributes, and extensions
Hey, I haven't shared updates on django-components in some time (last was on v0.122). Lots of new things! Some highlights:
\- Extensions \- Hook into component lifecycle, pre-/post-process components, add custom URLs, or custom commands.
\- Performance improvements (see 0.128 and 0.126) - 5x perf gain with Rust. Components can now be infinitely nested. Also, we now actively track performance of each release, see here. The aim is to get it to at least as fast as vanilla Django templates.
\- Add defaults to your components.
\- The {% html\_attrs %} tag allows you to manage class and style attributes with same granularity as seen in Vue.
\- Tests for your components are now easy to write with \``@djc_test`\` decorator. It ensures that all the internal state is reset after the test is done.
\- More debugging tools, such as to highlight components and / or slots in the UI
\- When using template tags from django-components, like `{% component %}`, our tags have extra nicities, such as allowing you to define literal lists and dictionaries when writing an input for a component. You too can write template tags with these extra features, with \``@template_tag`\` decorator, or by subclassing from \``BaseNode`\`

PyAwaitable 2.0.0 Released - Call Asynchronous Code From An Extension Module
Hi everyone! I've released PyAwaitable with a major version bump to 2. I completely redesigned how it's distributed, so now it's solely a build time dependency; PyAwaitable doesn't have to be installed at runtime in your C extensions, making it extremely portable.
## What My Project Does
PyAwaitable is a library for using async/await with extension modules. Python's C API doesn't provide this by default, so PyAwaitable is pretty much the next best thing!
Anyways, in the past, basically all asynchronous functions have had to be implemented in pure-Python, or use some transpiler like Cython to generate a coroutine object at build time. In general, you can't just write a C function that can be used with await at a Python level.
PyAwaitable lets you break that barrier; C extensions, without any additional transpilation step, can use PyAwaitable to very easily use async/await natively.
## Target audience
I'm targetting anyone who develops C extensions, or anyone who maintains transpilers for C extensions looking to add/improve asynchronous support (for example, mypyc).
## Comparison
There basically isn't any other library like PyAwaitable that I know of. If you look up anything along the lines of "Using async in Python's C API," you get led to some of my DPO threads
