I am trying to define a dataclass for my model in the same class of the model, where i have defined the table.

this is my model class,

from dataclasses import dataclass, field
from sqlalchemy import Column, Integer, String
from Database.db_setup import Base


@dataclass
class Director(Base):
    __tablename__ = 'directors'

    id: int = field(init=False, default=None)
    name: str

    id = Column(Integer, primary_key=True, nullable=False)
    name = Column(String, nullable=False, unique=True)

this is my gateway class where i am trying to use it

from src.Database.db_setup import Session
from src.Database.directors.director_model import Director
from sqlalchemy.exc import IntegrityError


def add_director(director_data: Director):
    session = Session()
    new_director = Director(name=director_data.name)
    try:
        session.add(new_director)
        session.commit()
        print(f"Added Director '{director_data.name}' successfully.")
    except IntegrityError:
        print(f"Error adding director: Director with name {director_data.name} already exists.")
        session.rollback()
    except Exception as e:
        print(f"Error adding director: {e}")
        session.rollback()
    finally:
        session.close()


tempdirector = Director("Jerry")
add_director(tempdirector)

Traceback (most recent call last):
File “/home/student-4318/src/Database/directors/gateway.py”, line 23, in
temdirector = Director(“Jerry”)
TypeError: init() takes 1 positional argument but 2 were given

I am getting this error message , how can i ignore the id as an positional argument because it gets generated by itself.
