Elbette JSON’u formatlamaktan çok daha iyi şekillerde bundan faydalanabilirsiniz. 😉

### `orjson` mı Response Model mi { #orjson-or-response-model }

Aradığınız şey performans ise, büyük olasılıkla bir `orjson` response’tan ziyade bir [Response Model](../tutorial/response-model.md) kullanmak daha iyi olacaktır.

# Form Model'leri { #form-models }

FastAPI'de **form field**'larını tanımlamak için **Pydantic model**'lerini kullanabilirsiniz.

/// info | Bilgi

Form'ları kullanmak için önce [`python-multipart`](https://github.com/Kludex/python-multipart)'ı yükleyin.

Bir [virtual environment](../virtual-environments.md) oluşturduğunuzdan, onu etkinleştirdiğinizden ve ardından paketi kurduğunuzdan emin olun. Örneğin:

```console
$ pip install python-multipart
```

[XML](https://en.wikipedia.org/wiki/XML)レスポンスを返したいとしましょう。

XMLを文字列にし、`Response` に含め、それを返します。

## Response Model の仕組み { #how-a-response-model-works }

path operation で [Response Model - 戻り値の型](../tutorial/response-model.md) を宣言すると、**FastAPI** はそれを使って Pydantic によりデータをJSONにシリアライズします。

## Как работает модель ответа { #how-a-response-model-works }

Когда вы объявляете [Модель ответа - возвращаемый тип](../tutorial/response-model.md) в операции пути, **FastAPI** будет использовать её для сериализации данных в JSON с помощью Pydantic.
