Instance of ‘SQLAlchemy’ has no ‘Column’ member (no-member)

EDIT: After read and try np8’s answer my previous answer is wrong there is a package you have to install, which is pylint_flask_sqlalchemy

so the answer will be

on your project directory find folder .vscode (if you dont have it, just create it) then create file settings.json and add this line

{
    # You have to put it in this order to make it works
    "python.linting.pylintArgs": [
        "--load-plugins",
        "pylint_flask_sqlalchemy",
        "pylint_flask",                 # This package is optional
    ]
}

You also need to have pylint-flask-sqlalchemy and if you want to use pylint-flask install on your current python environment:

pip install pylint-flask-sqlalchemy
pip install pylint-flask
