    Set the import out the class.

    from datetime import datetime
    
    last_updated = db.Column(db.DateTime, default=datetime.now())
    

    or

    import datetime
    
    last_updated = db.Column(db.DateTime, default=datetime.datetime.now())

    Look at your line:

    last_updated = db.Column(db.DateTime, default=datetime.datetime.now)
    

    There is no datetime.datetime.now attribute in python. However, there is a datetime.datetime.now() function in python. You were just missing a pair of parentheses.

    last_updated = db.Column(db.DateTime, default=db.func.current_timestamp())
    

    I think this will work

    Try to use datetime.datetime.utcnow(). This works for me.
