Is it worthy to use frontend framework like react or vue with Django?

Django comes up with DTL which has enough power to create pretty much everything.

But in the world full of JS frameworks I'd like to know is there any benefit if using javascript frontend frameworks along with Django?

Also give some use cases!

Tasks - is APScheduler better than Cron/Schedule modules?

I want the best one to automate a task, my function makes an API call every 15 minutes and saves data to csv and then calculates that CSV data to show on a chart. What task module would be the best in my case? APScheduler/Cron/Schedule/Celery?

PS: I'll be deploying to Heroku, so I'd appreciate anyone telling me about compatibility issues with Heroku.

Can passing Flask app context to multiple processes lead to problems while performing database operations using Flask-SQLAlchemy?

I am developing a backend which requires some processes to be spawned automatically, and constantly perform database operations from there. I am making use of the Flask SQLAlchemy ORM to interact with the database.

I was able to pass the 'app' variable as an argument to a new process, and perform DB operations from there. But the application requires several such processes to be running at once. Thus, several processes can be making database operations using the Flask app context, in addition to the APIs created inside of Flask itself. Can someone please tell me if this will lead to some sort of a conflict/error?

Thanks in advance!

Long term impact of using UUID as a unique identifier for models

I am developing an app that enables users to post discussion questions and allows other users to react and rate the questions. However, instead of using pk or id to map question urls I'm thinking about creating unique ids for each question using UUID. This is to prevent users from both monitoring site usage and being able to quickly iterate through questions by incrementing id.

So far, I've decided to assign each question on creation a unique id: uuid.uuid4().hex\[:6\].upper(). However, I was wondering the long term effect of this implementation. Every time I create a new object, Django will have to iterate through all existing questions. Will this have a significant computational effect over time? If so, are there any other more efficient implementations of assigning unique ids? Perform some function on the id (but then wouldn't some original issues persist)?

I made an IMDB webscraper

So this is pretty beginner, but it's my first real project, and today I finished the first version of it. Without going into to much detail, the user pastes a link to IMDB and the program scrapes the shows, gets an average rating for each season, the entire show, creates a graph with the average of each season, and then shows the user IMDB's top 250 rated TV shows and gives them the option to search for a show and see if it's in the top 250. That's pretty simplified and I won't paste all 200+ lines of code but [here is the github](https://github.com/NerdyBread/IMDB-Webscraping) if anyone is interested. I'd love any feedback that anyone has, good or bad.

How to use Django Model Managers? understanding the Django ORM

# Model managers, understanding the Django ORM

[A video in YouTube](https://preview.redd.it/gb9xndstl3k51.png?width=1280&format=png&auto=webp&s=962eb3a6e6e63e9e28d206348e2bd751e7f29171)

&#x200B;

Hey guys, recently while working on a project I bumped into model managers. I knew they existed but didn't bother to learn more about them. But then I had to work with my own custom user models in Django.

So I plowed through the documentation and learned it all.

I prepared a video for anyone who intends to learn more about them :) Keep Learning!!!

How do I optimise my Django project for speed and performance?

Hey guys, hope you are all doing well. I recently deployed a django app to Heroku and it is super slow (5 - 6 seconds on average for a page), in part because I live in India and that's also where the majority of my users are. However, I recently tried shifting my site to AWS Lambda on the Mumbai server, which resulted in RELATIVELY faster load times (2 - 3 seconds for non database pages; pages that fetch stuff from the database are approximately the same if not even slower). This led me to believe that my site may be genuinely slow because the code isn't very efficient. To confirm this, I tested the response times locally using Google Chrome Dev tools. Sure enough, the site pages were taking 1 - 2 seconds on avg. to load locally. For comparison, I also checked the response time locally for a django blog project I had done earlier, and it was around 100 - 200 milliseconds. My current Django app is actually a marketplace, and is a fair bit more complicated than the blog, but it still shouldn't be 10X slower. Any tips on how I can make it faster /
