I know a little bit of flask but I'm more comfortable with laravel and it has ORM, so I was a bit hesitant to whether I should keep learning flask or jump to Django but your series convinced me to keep using flask

Is there a way to have multiple databases used?

[denniskiboi]

The tutorials are extremely helpful. I however couldn't access the free course on the provided link. Is it still available?

When running I got RuntimeError: Working outside of application context. If it's of any help, I discover somewhere else that instead of python I had to run flask shell. It worked.

Hi Sir, my program doesn't create a db.sqlite3 file, instead it creates a directory 'instances' with no files inside it. I mean it fails to create the said file. What might be to possible reason? Thanks

[obajbola]

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.

Thats the error message i get when i ran db.create_all(). pls any solution how to add the app.app_context() to my code??

[kmishy]

What is benefit of using sqlalchemy ORM over directly using respective database driver?
We learnt SQL, now why to put effort to learn sqlalchemy?

[ahmadabdallah]

I keep running into this error: RuntimeError: Working outside of application context.

Hi
thanks for this video... I would like to ask you if is it possible to create the table from the python file code, instead of gettign into the terminal???:

if "__name__" == "__main__":
db.create_all()
app.run(debug=True)

For this I'm using:

And my laragon local server is on

[Veektaw]

db.create_all() no longer works for Python3.10? It keeps talking about application context
