## `PATCH`による部分的な更新

また、<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/PATCH" class="external-link" target="_blank">HTTPの`PATCH`</a>操作でデータを*部分的に*更新することもできます。

つまり、更新したいデータだけを送信して、残りはそのままにしておくことができます。

/// note | "備考"

`PATCH`は`PUT`よりもあまり使われておらず、知られていません。

また、多くのチームは部分的な更新であっても`PUT`だけを使用しています。

**FastAPI** はどんな制限も課けていないので、それらを使うのは **自由** です。

しかし、このガイドでは、それらがどのように使用されることを意図しているかを多かれ少なかれ、示しています。

'StaticFiles'를 사용하여 디렉토리에서 정적 파일을 자동으로 제공할 수 있습니다.

## `StaticFiles` 사용

* `StaticFiles` 임포트합니다.
* 특정 경로에 `StaticFiles()` 인스턴스를 "마운트" 합니다.

```Python hl_lines="2  6"

/// note | "기술적 세부사항"

`from starlette.staticfiles import StaticFiles` 를 사용할 수도 있습니다.

**FastAPI**는 단지 개발자인, 당신에게 편의를 제공하기 위해 `fastapi.static files` 와 동일한 `starlett.static files`를 제공합니다. 하지만 사실 이것은 Starlett에서 직접 온 것입니다.

    echo "# Size of $TF_WHEEL is $WHEEL_MEGABYTES / $LARGEST_OK_SIZE megabytes." >&3
    test "$WHEEL_MEGABYTES" -le "$LARGEST_OK_SIZE"
}

# Note: this runs before the tests further down the file, so TF is installed in
# the venv and the venv is active when those tests run. The venv gets cleaned
# up in teardown_file() above.
@test "Wheel is installable" {

```Python hl_lines="7"

/// note

请记住，在这种情况下 FastAPI 将不会检查列表的内容。

例如，`List[int]` 将检查（并记录到文档）列表的内容必须是整数。但是单独的 `list` 不会。

///

## 声明更多元数据

你可以添加更多有关该参数的信息。

这些信息将包含在生成的 OpenAPI 模式中，并由文档用户界面和外部工具所使用。

/// note

请记住，不同的工具对 OpenAPI 的支持程度可能不同。

其中一些可能不会展示所有已声明的额外信息，尽管在大多数情况下，缺少的这部分功能已经计划进行开发。
