Description

How can I add an attribute to a SQLModel instance? Let's say "group". I tried setattr("group", "Z") and hero.group = "Z", but it's not working. I want to add attributes to the instance since the SQLModel instance I'm returning in my mutation needs to match my GraphQL schema, which is slightly different.

hero.__dict__["group"] = "Z" works
