init.py flask-sqlalchemy

[yasmine-pog]

i don't know how to fix this issue

[ghost]

(Capitals don't matter btw) Try: pip uninstall Flask-SQLAlchemy pip install -U Flask-SQLAlchemy

Then it should work, worked for me both on Ubuntu 20.04 and Windows 10

Hi Guys I am trying to access the app.config from init.py in views.py but it is not recognising app.config I just want to access the app.config in views.py. Do i need to import something?

in init.py def create_app(): app = Flask(name) app.config['SECRET_KEY'] = 'xftry' app.config['UPLOAD_FOLDER'] = myfolder

In views.py: (not recognising app) f.save(os.path.join(app.config['UPLOAD_FOLDER'], f.filename))

Thank you

Hi,

Could someone help with this error please?

I've uninstalled and then re-installed as per Bludenz recommendations.

I just fixed it. :)

My default Python version is Python 3.8.10.

I've updated the Python interpreter in VSCode to match the version I'm running and it's cleared that error.

cntrl + shift + p python: select interpreter Choose correct version.
