まず、エディタ、mypy、その他のツールがこれをどう見るかを見てみます。

`BaseUser` には基本フィールドがあります。次に `UserIn` が `BaseUser` を継承して `password` フィールドを追加するため、両方のモデルのフィールドがすべて含まれます。

関数の戻り値の型を `BaseUser` としてアノテーションしますが、実際には `UserIn` インスタンスを返しています。

エディタやmypyなどのツールはこれに文句を言いません。typingの観点では、`UserIn` は `BaseUser` のサブクラスであり、期待されるものが `BaseUser` であれば `UserIn` は*有効*な型だからです。

### `**user_in.model_dump()` について { #about-user-in-model-dump }

#### Pydanticの`.model_dump()` { #pydantics-model-dump }

`user_in`は`UserIn`クラスのPydanticモデルです。

Pydanticモデルには、モデルのデータを含む`dict`を返す`.model_dump()`メソッドがあります。

そこで、以下のようなPydanticオブジェクト`user_in`を作成すると:

```Python
user_in = UserIn(username="john", password="secret", email="******@****.***")
```
