py2exe.com - flask app to convert python files to exe online

Hi,

I made a website (https://py2exe.com/) that compiles python to exe in the cloud. It could be useful for someone that wants to make .exe from python on linux, which is quite difficult to do.

The website is written in flask and the compilation is done via pyinstaller through wine. I would really appreciate it if someone could try it out with their project and share their thoughts.

The code is available on github (https://github.com/cenekp74/py2exe). I would love to hear your thoughts on my implementation of celery task queue or any other part of the flask app since I am not an expert and would love to improve.

Thanks!

WhiteNoise with Nginx for Django

I'm working on deploying a Django application, and I'm trying to figure out the best way to handle static files. Right now, I'm using WhiteNoise to serve static files.

My plan is to use Nginx as a reverse proxy for the Django app (running on Gunicorn) and also to serve static files. However, I'm not entirely sure how to configure Nginx to work alongside WhiteNoise.

1. Should I disable WhiteNoise entirely in production and let Nginx handle all static files?
2. If I keep WhiteNoise enabled, how should the Nginx configuration look?
3. Are there any pros/cons to using both together, or should I stick with one solution?

How does the search algorithm work?

I am creating a web application in which registered users will have the opportunity to use a storage in which to store all their mp3 and wav files.
When they memorize them obviously they can listen to them and download them.
I created the user's song search system, so that he can individually select those that interest him more easily. The problem is that my system is very ugly: I take the user's input and check if the string he typed is inside the real_name column (of the file, file names stored in directories are changed to werkzeug.secure_filename) in the database and returns it.
Example: the user writes "I love" and if he presses enter the site returns "I love you.mp3", "I love him.wav", etc.
The problem is that a few small variations are enough to not give anything back.
Example: The user writes "I lo v," and the site returns nothing.
Is there an efficient algorithm?

Tiny Python library that turns functions into GUI apps


Hey! I made a small tool that lets you create GUI applications just by writing normal Python functions. It's inspired by FastAPI-Typer, but for desktop-mobile GUIs.

# Basic example:

from functogui import App, intUi, boolReturn

def iseven(number: int = intUi(4)) -> boolReturn:
    return number % 2 == 0

App(iseven)

That's it - it creates a complete GUI with a slider and shows the result in real-time. Useful for quick tools and prototypes when you don't want to mess with UI code.

Built with Kivy, supports file handling, image preview, and different input types. Would love to hear your thoughts or suggestions!

Developing locally after deployment? (Oauth issues)

I built my flask app and just deployed it on python anywhere. I updated my oauth credentials to point to the real site rather than localhost.

My login functionality no longer works locally (I'm only supporting Google login, no passwords/email).

How do others get around this? Perhaps have something set in the code so if app is running in debug mode the user skips login?

Built a Drag-and-Drop GUI Builder for CustomTkinter – Check It Out and Share Your Thoughts!

Hey Python devs!

I recently built a drag-and-drop GUI tool for customTkinter to simplify designing interfaces. It lets you visually create UIs and export the code directly, which has been super helpful for my projects.

I’d love to hear your thoughts and feedback on it! You can check it out on GitHub https://github.com/Proxlight/Buildfy-Free.git

I’m particularly interested in:
• Usability: Is the drag-and-drop interface intuitive?
• Features: What could make it even better?

Feel free to give it a try and let me know what you think. Any feedback would be amazing!

Thanks!

Where to host Flask App

Hi everyone! I just developed my first flask app, and needed some assistance in getting it deployed as I've never done it before. My app uses multiple databases (SQLite currently) to keep track of events and participation for an organization I am in. I originally was going to use render since it was free but since it seems like it refreshes it won't be a good fit since it will wipe my dbs. I then looked at creating a PostgreSQL database on render but their free tier only lasts a month. If there is a way to host this for free I'd love to do that since the org is only about \~100 people and the website wouldn't be in use constantly and the likelihood of concurrent writes is very low. I was wondering if anyone knew a place where I could host this web app (hopefully for free), or for low cost if I can use SQLite as I'd rather not update everything atp. If anyone has any advice or helpful resources I'd greatly appreciate it!

I had following code:

avg_columns = ['Bx', 'By', 'Bz', 'G2 C03']
agg_map = {col: 'sum' for col in sum_columns}
agg_map.update({col: 'mean' for col in avg_columns})

df = df.groupby(['MAC C01', 'MAC C02', 'MAC C03'], as_index=False).agg(agg_map)

Logic in Views vs Logic on Models

Hey folks,

Apparently this is a frequently discussed topic.

Im doing a project using DRF. In this context i feel like the Views that are basically APIs should have logic, but my approach so far was that whatever touches a model, goes in the model.

Concrete example: one of my APIs has to change the Status of a Sales order. Then i will create a method in the SalesOrder model that will do the status change, along with any particular validation that it might want to do (example if you're changing it to completed/closed, ensure theres no open amount and the items were delivered)

Can you give me your thoughts about this approach and if its worth moving everything to either the views or to another "business logic" layer (or both)?

I dont really have crazy calculations or bigass logic for anything in particular, but i rather learn the proper way


Looking online i see all kinds of recommendations, the logic layer as well as the Thick Models, as well as "Model is simply the ORM". So i feel like it doesnt really matter as long as its consistent and is useful for the individual project?

Open-Source & Free Django App Generator - Select Design, Edit DB Tables, Extended User Fields, Add Celery, Social Login (GitHub), Docker

Hello guys!

[App-Generator.dev](https://App-Generator.dev) service released a simple Django App Generator that might help to customize, generate, and download the code as a ZIP archive or from GitHub.



[https://app-generator.dev/tools/django-generator/](https://app-generator.dev/tools/django-generator/)



The users can customize:

* UI: AdminLTE, Soft Dashboard .. etc (10 designs)
* DB Driver: SQLite (default), PgSQ, MySql/MariaDB
* DB Tables - table relations supported
* Extended User Model
* (optional) Social Login: GitHub
* (optional) Celery - async tasks
* (optional) Dynamic API - each model can be managed via a secured DRF endpoint
* (optional) Docker
* (optional) Ci/CD scrips for Render

The generator code uses a combination of template code generation and Astor Library for AST manipulation - source code saved on GitHub as celery task



[https://github.com/app-generator/app-generator/blob/main/apps/tasks/tasks.py](https://github.com/app-generator/app-generator/blob/main/apps/tasks/tasks.py)



Currently, the tool generates around 20 apps/day and the code is automatically saved on GitHub:



[https://github.com/app-generator?tab=repositories](https://github.com/app-generator?tab=repositories)



In the long run, the plan is to integrate more OAuth providers, DataTables, and a visual page builder.

Thanks for feedback & suggestions.
