{!> ../../../docs_src/body_nested_models/tutorial004_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial004_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial004.py!}
    ```

Das würde bedeuten, dass **FastAPI** einen Body erwartet wie:

    {!> ../../../docs_src/body_nested_models/tutorial004_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial004_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial004.py!}
    ```

Это означает, что **FastAPI** будет ожидать тело запроса, аналогичное этому:

```Python hl_lines="9-11"
{!../../../docs_src/body_nested_models/tutorial004.py!}
```

### Use o sub-modelo como um tipo

E então podemos usa-lo como o tipo de um atributo:

```Python hl_lines="20"
{!../../../docs_src/body_nested_models/tutorial004.py!}
```

Isso significa que o **FastAPI** vai esperar um corpo similar à:

```JSON
{
    "name": "Foo",
    "description": "The pretender",

    {!> ../../../docs_src/body_nested_models/tutorial004_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial004_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial004.py!}
    ```

This would mean that **FastAPI** would expect a body similar to:

### 서브모델 정의

예를 들어, `Image` 모델을 선언할 수 있습니다:

```Python hl_lines="9-11"
{!../../../docs_src/body_nested_models/tutorial004.py!}
```

### 서브모듈을 타입으로 사용

그리고 어트리뷰트의 타입으로 사용할 수 있습니다:

```Python hl_lines="20"
{!../../../docs_src/body_nested_models/tutorial004.py!}
```

이는 **FastAPI**가 다음과 유사한 본문을 기대한다는 것을 의미합니다:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,

    {!> ../../../docs_src/body_nested_models/tutorial004_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial004_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial004.py!}
    ```

这意味着 **FastAPI** 将期望类似于以下内容的请求体：

```JSON
{

    ```

### ⚙️ 📊 🆎

& ⤴️ 👥 💪 ⚙️ ⚫️ 🆎 🔢:

=== "🐍 3️⃣.6️⃣ & 🔛"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial004.py!}
    ```

=== "🐍 3️⃣.9️⃣ & 🔛"

    ```Python hl_lines="20"
    {!> ../../../docs_src/body_nested_models/tutorial004_py39.py!}
    ```

=== "🐍 3️⃣.1️⃣0️⃣ & 🔛"

    ```Python hl_lines="18"

### サブモデルの定義

例えば、`Image`モデルを定義することができます:

```Python hl_lines="9 10 11"
{!../../../docs_src/body_nested_models/tutorial004.py!}
```

### サブモデルを型として使用

そして、それを属性の型として使用することができます:

```Python hl_lines="20"
{!../../../docs_src/body_nested_models/tutorial004.py!}
```

これは **FastAPI** が以下のようなボディを期待することを意味します:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
