    In Pydantic v1 hieß diese Methode `.dict()`, in Pydantic v2 wurde sie deprecated (aber immer noch unterstützt) und in `.model_dump()` umbenannt.

### `**user_in.dict()` 简介

#### Pydantic 的 `.dict()`

`user_in` 是类 `UserIn` 的 Pydantic 模型。

# Modelos Adicionais

Continuando com o exemplo anterior, será comum ter mais de um modelo relacionado.

Isso é especialmente o caso para modelos de usuários, porque:

* O **modelo de entrada** precisa ser capaz de ter uma senha.
* O **modelo de saída** não deve ter uma senha.
* O **modelo de banco de dados** provavelmente precisaria ter uma senha criptografada.

## モデルのリスト

同じように、オブジェクトのリストのレスポンスを宣言することができます。

そのためには、標準のPythonの`typing.List`を使用する:

```Python hl_lines="1 20"
{!../../../docs_src/extra_models/tutorial004.py!}
```

## 任意の`dict`を持つレスポンス

また、Pydanticモデルを使用せずに、キーと値の型だけを定義した任意の`dict`を使ってレスポンスを宣言することもできます。

    ```Python hl_lines="1  14-15  18-20  33"
    {!> ../../../docs_src/extra_models/tutorial003.py!}
    ```

## Deeply nested models

You can define arbitrarily deeply nested models:
