你也可以把檔案路徑傳給 `fastapi dev` 指令，它會推測要使用的 FastAPI app 物件：

```console
$ fastapi dev main.py
```

但這樣每次呼叫 `fastapi` 指令時都得記得傳入正確的路徑。

此外，其他工具可能找不到它，例如 [VS Code 擴充套件](editor-support.md) 或 [FastAPI Cloud](https://fastapicloud.com)，因此建議在 `pyproject.toml` 中使用 `entrypoint`。

## `fastapi dev` { #fastapi-dev }

執行 `fastapi dev` 會啟動開發模式。

If we had declared `-> HeroPublic`, your editor and linter would complain (rightfully so) that you are returning a `Hero` instead of a `HeroPublic`.

By declaring it in `response_model` we are telling **FastAPI** to do its thing, without interfering with the type annotations and the help from your editor and other tools.

///

### Read Heroes with `HeroPublic` { #read-heroes-with-heropublic }

     * not be set within all security descriptors even though the ACE was in
     * face inherited. If an inherited ACE is added to a parent the Windows
     * ACL editor will rebuild all children ACEs and set this flag accordingly.

     * @return whether this is an inherited ACE

    boolean isInherited();

`fastapi dev` コマンドにファイルパスを渡すこともでき、使用する FastAPI アプリオブジェクトを推測します:

```console
$ fastapi dev main.py
```

ただし、そのたびに `fastapi` コマンドを呼び出す際に正しいパスを渡す必要があります。

さらに、[VS Code 拡張機能](editor-support.md) や [FastAPI Cloud](https://fastapicloud.com) など、ほかのツールがそれを見つけられない場合があります。そのため、`pyproject.toml` の `entrypoint` を使用することを推奨します。

## `fastapi dev` { #fastapi-dev }

`fastapi dev` を実行すると、開発モードが有効になります。

```Python
images: list[Image]
```

이를 아래처럼:

{* ../../docs_src/body_nested_models/tutorial008_py310.py hl[13] *}

## 어디서나 편집기 지원 { #editor-support-everywhere }

그리고 어디서나 편집기 지원을 받을 수 있습니다.

리스트 내부 항목의 경우에도:

<img src="/img/tutorial/body-nested-models/image01.png">

Pydantic 모델 대신 `dict`로 직접 작업한다면 이런 종류의 편집기 지원을 받을 수 없습니다.

你也可以把文件路径传给 `fastapi dev` 命令，它会猜测要使用的 FastAPI 应用对象：

```console
$ fastapi dev main.py
```

但每次运行 `fastapi` 命令都需要记得传入正确的路径。

另外，其他工具可能找不到它，例如 [VS Code 扩展](editor-support.md) 或 [FastAPI Cloud](https://fastapicloud.com)，因此推荐在 `pyproject.toml` 中使用 `entrypoint`。

## `fastapi dev` { #fastapi-dev }

当你运行 `fastapi dev` 时，它将以开发模式运行。

In order to make changes to Gradle, you'll need:

* [Adoptium JDK](https://adoptium.net/temurin/archive/?version=17) (Java Development Kit) **version 17**. Fixed version is required to use [remote cache](#remote-build-cache).
* A text editor or IDE. We use and recommend [IntelliJ IDEA CE](http://www.jetbrains.com/idea/). IntelliJ Ultimate will also work. You'll need IntelliJ 2021.2.2 or newer.
* [git](https://git-scm.com/) and a [GitHub account](https://github.com/join).

你的模型的 JSON Schema 会成为生成的 OpenAPI Schema 的一部分，并显示在交互式 API 文档中：

<img src="/img/tutorial/body/image01.png">

并且，还会用于需要它们的每个*路径操作*的 API 文档中：

<img src="/img/tutorial/body/image02.png">

## 编辑器支持 { #editor-support }

在编辑器中，函数内部你会在各处得到类型提示与补全（如果接收的不是 Pydantic 模型，而是 `dict`，就不会有这样的支持）：

<img src="/img/tutorial/body/image03.png">

还支持检查错误的类型操作：

这并非偶然，整个框架都是围绕这种设计构建的。
