modifying User and Image

User:

from sqlalchemy import Column, String
from sqlalchemy.orm import Session

from bfs import UserBase
from data._roles import Roles


class User(UserBase):
    newColumn = Column(String)

    @classmethod
    def new(cls, creator: "User", login: str, password: str, name: str, roles: list[int], newColumn: str, db_sess: Session = None) -> "User":
        return super().new(creator, login, password, name, roles, db_sess, newColumn=newColumn)

    @staticmethod
    def _new(db_sess: Session, user_kwargs: dict, newColumn: str):
        user = User(**user_kwargs, newColumn=newColumn)
        changes = [("newColumn", newColumn)]
        return user, changes

    @staticmethod

        return User.new(fake_creator, "admin", "admin", "Админ", [Roles.admin], "newColumnValue", db_sess=db_sess)

Image:

# to use relationship you must name the file something other than image.py
# img.py for the example, because of the way sqlalchemy finds classes
image = orm.relationship("data.img.Image")
