**참고:** 기본 키 필드에 `int | None`을 사용하는 이유는, Python 코드에서 *`id` 없이 객체를 생성*할 수 있게 하기 위해서입니다(`id=None`). 데이터베이스가 *저장할 때 생성해 줄 것*이라고 가정합니다. SQLModel은 데이터베이스가 `id`를 제공한다는 것을 이해하고, 데이터베이스 스키마에서 *해당 열을 null이 아닌 `INTEGER`*로 정의합니다. 자세한 내용은 [기본 키에 대한 SQLModel 문서](https://sqlmodel.tiangolo.com/tutorial/create-db-and-table/#primary-key-id)를 참고하세요.

Ele também foi um dos primeiros frameworks a gerar um schema personalizado declarando a API inteira em JSON.

Ele não era baseado em um padrão como OpenAPI e JSON Schema. Então não seria simples integrá-lo com outras ferramentas, como Swagger UI. Mas novamente, era uma ideia muito inovadora.

Ele tem um recurso interessante e incomum: usando o mesmo framework, é possível criar APIs e também CLIs.
