Це дозволить Вам повторно **використовувати модель** в **різних місцях**, а також оголосити валідації та метадані для всіх параметрів одночасно. 😎

/// note | Нотатки

Ця можливість підтримується починаючи з версії FastAPI `0.115.0`. 🤓

## Параметри Заголовків з Використанням Pydantic Model

You can then use `Field` with model attributes:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[11:14] *}

`Field` works the same way as `Query`, `Path` and `Body`, it has all the same parameters, etc.

/// note | Technical Details

Actually, `Query`, `Path` and others you'll see next create objects of subclasses of a common `Param` class, which is itself a subclass of Pydantic's `FieldInfo` class.

# 查詢參數模型

如果你有一組具有相關性的**查詢參數**，你可以建立一個 **Pydantic 模型**來聲明它們。

這將允許你在**多個地方**去**重複使用模型**，並且一次性為所有參數聲明驗證和元資料 (metadata)。😎

/// note

FastAPI 從 `0.115.0` 版本開始支援這個特性。🤓

///

## 使用 Pydantic 模型的查詢參數

在一個 **Pydantic 模型**中聲明你需要的**查詢參數**，然後將參數聲明為 `Query`：

{* ../../docs_src/query_param_models/tutorial001_an_py310.py hl[9:13,17] *}

**FastAPI** 將會從請求的**查詢參數**中**提取**出**每個欄位**的資料，並將其提供給你定義的 Pydantic 模型。

`from starlette.responses import JSONResponse`를 사용할 수도 있습니다.

**FastAPI**는 개발자 여러분을 위한 편의성으로 `fastapi.responses`와 동일한 `starlette.responses`를 제공합니다. 그러나 사용 가능한 응답의 대부분은 Starlette에서 직접 제공됩니다. `status` 또한 마찬가지입니다.

## In Detail { #in-detail }

The marker `@pytest.mark.anyio` tells pytest that this test function should be called asynchronously:

{* ../../docs_src/async_tests/test_main.py hl[7] *}

/// tip

Note that the test function is now `async def` instead of just `def` as before when using the `TestClient`.

///

Then we can create an `AsyncClient` with the app, and send async requests to it, using `await`.

Это означает, что можно передавать только те данные, которые необходимо обновить, оставляя остальные нетронутыми.

/// note | Технические детали

`PATCH` менее распространен и известен, чем `PUT`.

А многие команды используют только `PUT`, даже для частичного обновления.
