Does anyone know of any themes that only change the color?

All of the themes I've found completely reformat the notebook. I'm looking for a way to simply make the page dark mode without changing anything else.

Or if anyone knows what changes I can make to the default css file to make the background black. For some reason it doesn't do anything when I change the values.

​

Thanks

Need help to not make yet another trash article on Medium

Hi all,

Over the last couple of months I've been posting here with some questions regarding background processing in Flask. It's been incredibly helpful and I've now got a working setup sorted running the following:

Flask Application Factory Pattern
Celery and Redis for background tasks
Docker deployment with docker-compose
Azure hosted and connected to Azure SQL Server

Getting Celery sorted took a while and a lot of the information was either not really there, required a lot of digging, was related more to Django than flask or did not go far enough in catering for a production setup of Flask and celery. In particular how to link to Gunicorn, integrations with pytest, and using with the app factory pattern.

To that end, I'd really like to give back a bit and do a bit of a write up on how I got a production ready setup working for flask with the above config, as I genuinely think it would be super useful.

My only concern is that a lot was trial and error. I could definitely use some help in proofreading both the code and some of the DevOps components (Dockerfiles spring to mind) to make sure I'm not putting out bad info.

A stock market telegram bot built with python and mongodb

Hey! Good people of reddit. I would like to showcase an intermediate level project I made. So here's a little background, many traders need to know when a certain stock Crosses a threshold for that there are many services and the one I used included 5-6 steps to set one trigger, so I thought that it would be nice if I could have my own bot deployed on a messaging app. Here I have built a telegram bot that allows users to set triggers for stock of their choice.
Users can set triggers for multiple stock and at multiple price points.
I have used the following :
1. yfinance, alpha vantage and telegram api
2. Mongodb

Github link: https://github.com/pratik-choudhari/StockNotify

I have added detailed readme and have kept multiple topics open for contributions. Do check it out😊
I would like hear from you in the comments, good or bad, anything!

How do you organize your Settings.py file to keep it clean?

My settings.py file is quickly growing in length and it is making it hard to maintain, add, or remove code. How should I go about cleaning it up and keeping the whole file clean? I was thinking of chopping it up into multiple files, but I am not sure of a good structure or organizational architecture for it.

I was thinking about taking all the one line variables that are being set and maybe putting them in their own files and keeping it clean that way or something like that. What do you guys think? What do you guys do? How do you keep your code clean and maintainable?

Should data be present in Docker-containerized db after applying migrations?

Been struggling with this for about a week now, and I’m probably not googling the right keywords.

I’m new to both django and docker. I’m able to stand up my web app and connect it to the Postgres db I created via docker-compose (db is created as a volume) but I’m running into a problem when I try to access data that should be on the db.

The behavior that confuses me:

If I navigate to localhost:8000 and try the “search” functionality (essentially should just be searching for the query within the db) before applying migrations I see in the logs two things:

1. The database logs trying to query the specific tables
2. Web app returns an error because those tables do not exist yet (need to apply migrations)

I also see the page error out. This is completely expected behavior IMO.

If I try this again after applying migrations (either manually or via an entry point) this is what I see:

1. The web app logs the GET requests of me navigating to the search page and my search query after I hit enter on the search page
2. Nothing is logged for the db container - shouldnt it still query the tables

I’m creating a Django portfolio to both build experience and become a better programmer and was looking for suggestions/tips/tools etc I can incorporate?

The idea here is to start by building a simple personal portfolio that includes apps for an about me page, a projects page, a blog and a ‘versions’ section which will keep note of my progress and modifications.

So far I’ve built out the about me, projects and blog apps using Python, JS and Bootstrap. I would like to continue adding new apps that are built with new concepts, tools and languages. For instance, what I plan on adding next is a Todo app built with React.

I’m looking for any suggestions as far as future apps I can build that can be implemented well with Django and Python. For example, developing a section built with TypeScript or another functional programming language.

Aside from new languages & tools, I’m also looking for general ideas that will test my knowledge and teach me new skills.

I appreciate any feedback or leaning tips that can be provided!

Flask or MERN for auction-like web applications?

I have experience with both Flask and MERN and there's a client who wants to create a web application for users to sell and bid on other products. Is there a better option between Flask and MERN for a robust web app like this? Do you have other recommendation regarding anything else related?

Thank you so much in advance:)
