see https://flask-security-too.readthedocs.io/en/stable/quickstart.html#basic-flask-sqlalchemy-lite-application

missing

If then imported I get

raise exc.NoReferencedTableError(
sqlalchemy.exc.NoReferencedTableError: Foreign key associated with column 'roles_users.role_id' could not find table 'role' with which to generate a foreign key to target column 'id'

when running the flask app

To get things working - be sure to change the tablename values to lower case "User"->"user" and "Role"->"role"
