migration.py
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
app = Flask(name)
app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql://myuser:password@localhost:5432/Rendermap_DB'
db = SQLAlchemy(app)
migrate = Migrate(app, db)
app.py from flask import Flask, jsonify, request
from models import db, User, Layouts
import config

app = Flask(name)
app.config['SQLALCHEMY_DATABASE_URI'] = config.DATABASE_URI

db.init_app(app) and i've set $env:FLASK_APP = "app.py"

and if I downgrate Flask :

Please do not write issues on this project when you are just asking for help fixing a bug in your own application. The issues board is for actual bugs in this package. The discussions board is for questions and requests for help. I have converted the issue to a discussion for you this time.

The issue is that you have two files, migration.py and app.py, and both duplicate the code that creates a Flask app. But you have added Flask-Migrate only to migration.py. When you use the flask db command, Flask uses app.py, which does not have Flask-Migrate, so the flask db command is not registered.

okay, sorry I wasn't aware of this distinction, just wondering ,how am I supposed to know if it's an 'actual' bug or not ? I think I'll stay cautious from now on and assume it's always my fault. Thanks for letting me know and for your help

[miguelgrinberg]

Exactly. If you don't have an actual bug to report, then you should post in the discussions board first. There is always time to file a bug later if needed.

I understand. As someone new to GitHub, I wasn't fully aware of the best practices and didn't intend to misuse the platform. I apologize for any inconvenience I may have caused
