Primero, echemos un vistazo rápido a las partes que cambian desde los ejemplos en el **Tutorial - User Guide** principal para [OAuth2 con Password (y hashing), Bearer con tokens JWT](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank}. Ahora usando scopes de OAuth2:

For example, as in the `Image` model we have a `url` field, we can declare it to be an instance of Pydantic's `HttpUrl` instead of a `str`:

Чтобы увидеть все варианты, которые у вас есть, ознакомьтесь с <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">обзором типов Pydantic</a>. Вы увидите некоторые примеры в следующей главе.

Например, так как в модели `Image` у нас есть поле `url`, то мы можем объявить его как тип `HttpUrl` из Pydantic вместо типа `str`:
