# Scopes OAuth2 { #oauth2-scopes }

Vous pouvez utiliser des scopes OAuth2 directement avec **FastAPI**, ils sont intégrés pour fonctionner de manière transparente.

Cela vous permettrait d’avoir un système d’autorisations plus fin, conforme au standard OAuth2, intégré à votre application OpenAPI (et à la documentation de l’API).

de clave primaria para que en el código Python podamos *crear un objeto sin un `id`* (`id=None`), asumiendo que la base de datos lo *generará al guardar*. SQLModel entiende que la base de datos proporcionará el `id` y *define la columna como un `INTEGER` no nulo* en el esquema de la base de datos. Consulta la [documentación de SQLModel sobre claves primarias](https://sqlmodel.tiangolo.com/tutorial/create-db-and-table/#primary-key-id) para más detalles.
