### Uso del parámetro `exclude_unset` de Pydantic { #using-pydantics-exclude-unset-parameter }

Si quieres recibir actualizaciones parciales, es muy útil usar el parámetro `exclude_unset` en el `.model_dump()` del modelo de Pydantic.

Como `item.model_dump(exclude_unset=True)`.

## Champs de liste avec paramètre de type { #list-fields-with-type-parameter }

Mais Python a une manière spécifique de déclarer des listes avec des types internes, ou « paramètres de type » :

### Déclarer une `list` avec un paramètre de type { #declare-a-list-with-a-type-parameter }

Bu tür durumlarda bir `Response` parametresi kullanabilirsiniz.

## Bir `Response` parametresi kullanın { #use-a-response-parameter }

*Path operation function* içinde `Response` tipinde bir parametre tanımlayabilirsiniz (cookie ve header'lar için yapabildiğiniz gibi).

Ardından bu *geçici (temporal)* `Response` nesnesi üzerinde `status_code` değerini ayarlayabilirsiniz.

# Cookie Parametre Modelleri { #cookie-parameter-models }

Birbirleriyle ilişkili bir **cookie** grubunuz varsa, bunları tanımlamak için bir **Pydantic model** oluşturabilirsiniz. 🍪

Bu sayede **model'i yeniden kullanabilir**, **birden fazla yerde** tekrar tekrar kullanabilir ve tüm parametreler için validation ve metadata'yı tek seferde tanımlayabilirsiniz. 😎

/// note | Not

This is supported since FastAPI version `0.115.0`. 🤓

///

如果你的版本較舊，嘗試使用 `Annotated` 會出錯。

請先至少 [升級 FastAPI 版本](../deployment/versions.md#upgrading-the-fastapi-versions) 到 0.95.1 再使用 `Annotated`。

///

## 在 `q` 參數的型別中使用 `Annotated` { #use-annotated-in-the-type-for-the-q-parameter }

還記得先前在 [Python 型別介紹](../python-types.md#type-hints-with-metadata-annotations) 提到可以用 `Annotated` 為參數加入中繼資料嗎？

現在就用在 FastAPI 上吧。🚀

我們原本的型別註記是：

```Python
q: str | None = None
```

///

## Использовать `Annotated` в типе для параметра `q` { #use-annotated-in-the-type-for-the-q-parameter }

Помните, я уже говорил, что `Annotated` можно использовать для добавления метаданных к параметрам в разделе [Введение в типы Python](../python-types.md#type-hints-with-metadata-annotations)?

        return getByName(host, type, scope, null);
    }

    /**
     * Determines the address of a host given its host name with a specific server.
     * The additional <code>svr</code> parameter specifies the address to
     * query. This might be the address of a specific host, a name server,
     * or a broadcast address.
     *
     * @param host the name to resolve

# En-têtes de réponse { #response-headers }

## Utiliser un paramètre `Response` { #use-a-response-parameter }

Vous pouvez déclarer un paramètre de type `Response` dans votre fonction de chemin d'accès (comme vous pouvez le faire pour les cookies).

Vous pouvez ensuite définir des en-têtes dans cet objet de réponse temporaire.
