It was awesome thanks a lot just a little input in for loop if you replace{{ todo.id }}with {{loop.index}} it ll automatically update the indices if you delete any in the middle or top
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.
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 ❤️🙏
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.
@@ashiwal9910 Just above db=SQLAlchmey (app) add this line: with app.app_context(): -> By doing this you will get instance folder 📁 in that you can see .db file -> If you don't want to do this just use SQLAlchmey version 2.5.1 (pip install flask-SQLAlchemy==2.5.1) you can easily push data from the python shell (ex: >>> from app import db >>> db.create_all() ) I hope this helps you :(
I'm very confused right from the start (1:45). Where are you entering: git mkdir flask-todo I think its just in your terminal right? I did this in my terminal and it says 'mkdir is not a command'. I installed 'git' too so I don't understand this. If take out 'git' and just enter 'mkdir flask-todo' it works but my "Hello World" website doesn't work in the following steps.
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
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?
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.
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
Thanks for the tutorial! However im running into a slight issue. Im using pycharm as my IDE. i was not able to install FlaskSQLAlchemy the normal way. it would throw an error. So i had to resort to using the command "python -m easy_install SQLAlchemy" So i managed to install it with that command, but now despite it being in the right venv, showing in the list and all when trying to import it it throws the following error: "No module named 'flask_sqlalchemy'" Even after googling, all the answers i found that matched my IDE and OS (being win10) i still cant figure out what the problem is. Do you have any idea what the problem could be?
Hey man nice tutorial. I made the app by following the tutorial but in my app the title of the todo always says title instead of the title that I put in to the text box and I can't figure out what is wrong.
It depends on what you want to do. Both are great frameworks. Flask is more lightweight and easier for beginners. However, if you want an app with user management/authentication, then I would go with Django since it takes care of a lot of things for you.
@@patloeber the only reason I ask is because I saw online many advice Django because its easy and very powerful. And as you said Django does does a lot of things for you. So now as a noob i dont know on which to focus on? Or maybe I should learn both? I did saw all your videos and they did help me a lot by the way. I have good understandings of "intermediate" Python skills
At 14:32 I am getting this error - File "F:\flask-todo\venv\lib\site-packages\werkzeug\local.py", line 508, in _get_current_object raise RuntimeError(unbound_message) from None RuntimeError: Working outside of application context. This typically means that you attempted to use functionality that needed the current application. To solve this, set up an application context with app.app_context(). See the documentation for more information.
Don't know which error you're having... I got an error related to context. With a slight code modification I got the result expected. I'm sending the code, in case you got the same error: Right at the end of the app.py file: if __name__ == '__main__': with app.app_context(): db.create_all() app.run(debug=True) Hope it helps!

Thanks a lot!
Patrick would love u to do a separate tutorial on using flask sql alchemy, it is much needed!!
It is an excellent course tutorial with professional Engine Good Luck ,
Great tutorial. Very Helpful. Thank You So Much!
Thanks!
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?
Perfect! Simple and clear, like always.
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.
I am stuck there can u pls guide me?

Hey, i was following along up until adding a database. SQLAlchemy was installed but now its not working when i run the app.py file
its saying that RuntimeError: Working outside of application context.
Thanks for the tutorial!
However im running into a slight issue.
Im using pycharm as my IDE. i was not able to install FlaskSQLAlchemy the normal way. it would throw an error. So i had to resort to using the command
"python -m easy_install SQLAlchemy"
So i managed to install it with that command, but now despite it being in the right venv, showing in the list and all when trying to import it it throws the following error:
"No module named 'flask_sqlalchemy'"
Even after googling, all the answers i found that matched my IDE and OS (being win10) i still cant figure out what the problem is.
Do you have any idea what the problem could be?
solved my own question. make sure to follow his tutorial letter by letter. theres two different flask sql alchemy packages.
I'm stuck on one error Windows is not support crypt any Idea how to solve it? I'm using VS Code and Windows 10
thank you so much .... an amazing video...

I do have to ask a question. What is better to learn Flask or Django? Expecialy for begginer

Hey, how would I make it so each user that logins in has their own task app?
any tutorial on flask with Postgres sir?
SQLalchemy allows you to simply connect to a postgreSQL database AFAIK.
Nice job dude, any plans for a django one?
Django crash course is on my list too :)
Could you please also show how to build Machine learning Apps using flask..
Yes, I do have one more with pytorch and flask right now...
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?
