I’m using Flask and SQLAlchemy (not flask-sqlalchemy)

I’m trying to get access to the flask config from my database code, but it’s telling me that I’m not in an application context, probably because the App is not yet fully initialized.

I have app.py:

from flask import Flask

from root.views.calibration_views import calibration

nwm_app = Flask(__name__)
nwm_app.config.from_pyfile('myConfig.cfg')
print('config', nwm_app.config)

My calibration_views file imports database.py, which looks like this:

from sqlalchemy import URL, create_engine
from sqlalchemy.orm import sessionmaker

from flask import current_app as nwm_app


url = URL.create(
    drivername="postgresql",
    username="postgres",
    password="postgres",
    host="localhost",
    database="flask_test"
)
engine = create_engine(url, echo=True)

with nwm_app.app_context():
    print('config', nwm_app.config)


Session = sessionmaker(bind=engine)

I’m trying to get the config object using current_app, which avoids the Python error about circular imports, but I still get

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.

The nwm_app.app_context() was my attempt to fix it, but it had no effect
