Attributeerror: 'sqlalchemy' Object Has No Attribute 'models'

AttributeError: sqlalchemy object has no attribute 'Models' and some times ModuleNotFoundError: No module named 'models' error is occurring. I already installed all requirements li

Solution 1:

Make shure in your models.py in your db object is

db = SQLAlchemy()

NOT db = SQLAlchemy , because SQLAlchemy is a class

Solution 2:

If it doesn't work try the following.

db.init_app(app)

For example

#main.pyfrom flask import Flask
from flask_sqlalchemy import SQLAlchemy

app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///database.db'# Database URL
db = SQLAlchemy(app)
db.init_app(app)
