Python Flask Beginner Tutorial - Todo App - Crash Course

Lol, flask is a lot easier than django. I don't know why i'm learning django and not flask 🤨

GOOD DAY SIR
I MAY BE HAVING A PROBLEM ON THE DB_SQLITE TABLE
I WONT AUTOMATICALLY CREATE ANOTHER FOLDER
I FOLLOW ALL YOUR INSTRUCTIONS BUT IT WONT JUST CREATE ANOTHER FOLDER AND JUST HAVE AN ERROR

Hello Sir. Great tutorial, especially for a beginner. I created the app following the tutorial, but, when I tried deploying it using Vercel, it showed "500 Internal Server Error". However, it works perfectly fine when I tested it using the terminal on my local server... Please provide guidance

It is an excellent course tutorial with professional Engine Good Luck ,

Not getting "db.sqlite" to create. I will post my code below. working on a Mac like the video. even tried adding the "with app.app_context():" that other commenters have suggested. no luck

Get this error while activate env...someone help me out

error:-

To anyone having issues w the SQLAlchemy thingy or the app not running properly add this below your todo class (under it, not in it):

with app.app_context():
db.create_all()

A really kind stranger in a Discord helped me solve this & I wanted to pay it forward. :)

As of Flask-SQLAlchemy 3.0, all access to db.engine (and db.session) requires an active Flask application context. db.create_all uses db.engine, so it requires an app context.

Very good tutorial! I wish to add the functionality of deleting all the items at once by the click of a button ('Clear todos', for example). Does someone know how I could do this?

Thank you for the awesome tutorial!

Why whenever I try to learn stuff like this all I ever get are error messages and I never get the correct result even if I copy everything exact?

Could you mind please explain why you Visual Studio instead of say Jupyter. I tried following this in a Jupyter notebook but the program crashed and couldn't create a web page. It would have been helpful if you gave a little explanation about why you are using Visual Studio and whether it must be done exactly like that. I did everything the same way in visual studio and got the same error again.

Lol tf was that voice

One thing i don’t understand is: why does he create a new database every time the program gets run. wouldn’t it be better to check if a db exists?

thanks again

I love the Semantixc UI! It is very easy to style the page! And I liked your video as well and subscribed! Amazing content! Keep it up the good videos! It helps on my programming ❤️🙏

Great tutorial

Super!
Thanx for it!

Thank You for the video.

What about implementing "create","delete" etc in an async manner?

Hey, how would I make it so each user that logins in has their own task app?

This was very satisfying. The topping was your introduction to Semantic UI giving more possibilities from using bootstrap. Now to learn how to upload photos! Thank you for this tutorial.
