• I already checked if it is not related to SQLModel but to SQLAlchemy.

Example Code

from sqlmodel import Field, Session, SQLModel, create_engine, select class Hero(SQLModel, table=True): id: int | None = Field(default=None, primary_key=True) name: str hero_1 = Hero(name="Foo") engine = create_engine("sqlite://database.db") SQLModel.metadata.create_all(engine) with Session(engine) as session: session.add(hero_1) session.commit() with Session(engine) as session: hero = session.exec(select(Hero)).one() x = dict[int, Hero] = {hero.id: hero}

Description

• Create a Hero Model
• Save is to the database
• Query it from the database
• Run mypy
• See error:

scratch.py:20: error: Dict entry 0 has incompatible type "int | None": "Hero"; expected "int": "Hero" [dict-item 

Is there anyway for sqlmodel / mypy to resolve the fact that id can't be optional here?

You can add assert hero.id is not None before that line.

I don't think there are other methods. Only checking the value in runtime
