We receive in the request a `HeroCreate` *data model*, and from it, we create a `Hero` *table model*.

This new *table model* `Hero` will have the fields sent by the client, and will also have an `id` generated by the database.

Then we return the same *table model* `Hero` as is from the function. But as we declare the `response_model` with the `HeroPublic` *data model*, **FastAPI** will use `HeroPublic` to validate and serialize the data.
