Error in Tutorial 2

[Asaduddin18]

I am getting this error in tutorial 2 and I am unable to create the database to store the user sign-up info

from flask_sqlalchemy import SQLAlchemy
from .extension import SQLAlchemy
from .model import _QueryProperty
class DefaultMeta(BindMetaMixin, NameMetaMixin, sa.orm.DeclarativeMeta):
AttributeError: module 'sqlalchemy.orm' has no attribute 'DeclarativeMeta'

Flask-SQLAlchemy 3 no longer accepts an app argument to methods like create_all. Instead, it always requires an active Flask application context. There is no need for the create_database function. So instead write this in the create app function

with app.app_context():
db.create_all()

i hope this solves your problem

I had a similar error giving me sqlite3.OperationalError: no such table: user. This fix worked though. Thanks @prranavv!
