I'm working on the project1 from cs50web course.

Getting the following problem using flask and SQLAlchemy: "Instance of 'scoped_session' has no 'execute' memberpylint(no-member)".

I use Ubuntu 18.04, Flask. I suppose that the problem is somehow related to SQLAlchemy libarary or some adjustments should be done to the confiquration files.

How can I fix this problem?

They are warnings from pylint. You can tell pylint to ignore that error by create file .pylintrc in your folder with contains:

ignored-classes=SQLObject,Registrant,scoped_session

You need to import from flask_sqlalchemy import SQLAlchemy

and then create a instance of it by writing db = sqlalchemy(app)

This way

  • Not everyone is running a Flask app. This is not about Flask packages, but about SQLAlchemy and Pylint errors.
