У Pydantic есть официальное <a href="https://docs.pydantic.dev/latest/migration/" class="external-link" target="_blank">руководство по миграции</a> с v1 на v2.

Там также описано, что изменилось, как валидации стали более корректными и строгими, возможные нюансы и т.д.

## Guía oficial { #official-guide }

Pydantic tiene una <a href="https://docs.pydantic.dev/latest/migration/" class="external-link" target="_blank">Guía de migración</a> oficial de v1 a v2.

También incluye qué cambió, cómo las validaciones ahora son más correctas y estrictas, posibles consideraciones, etc.

FastAPIはこれをするために、Pydanticモデルの`.dict()`を<a href="https://docs.pydantic.dev/latest/concepts/serialization/#modeldict" class="external-link" target="_blank">その`exclude_unset`パラメータ</a>で使用しています。

以下も使用することができます:

* `response_model_exclude_defaults=True`
* `response_model_exclude_none=True`

Этого можно добиться, используя <a href="https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator" class="external-link" target="_blank">`AfterValidator` Pydantic</a> внутри `Annotated`.
