Why do I keep getting 'ImportError: cannot import name db'?

QUESTION

Why do I keep getting 'ImportError: cannot import name db'?

Asked 2018-Feb-13 at 09:58

I am following this tutorial: getting started with flask-login.

However I am stuck at step 5 where I start to use SQLAlchemy. I believe the problem might be circular importing, based on what I have read but I'm still a little new to Python coding. This web app is a little project I am doing in my free time.

You are correct you have a circle import issue.

At app.py you import from noteapp.models import db,
and at models.py you import from noteapp.app import app

A quick fix could be: at models.py use db = SQLAlchemy() without the app.
At the app.py module, import db from models.py and do db.init_app(app)

also remove db = SQLAlchemy(app) from your app.py

your app.py should look like this..
