入力モデルがまだ検証されていることに注目してください。

そのため、すべての属性を省略できる部分的な変更を受け取りたい場合は、すべての属性をオプションとしてマークしたモデルを用意する必要があります（デフォルト値または`None`を使用して）。

**更新** のためのオプション値がすべて設定されているモデルと、**作成** のための必須値が設定されているモデルを区別するには、[追加モデル](extra-models.md){.internal-link target=_blank}で説明されている考え方を利用することができます。

    disabled = user_dict["disabled"],
    hashed_password = user_dict["hashed_password"],
)
```

/// info

Eine ausführlichere Erklärung von `**user_dict` finden Sie in [der Dokumentation für **Extra Modelle**](../extra-models.md#uber-user_indict){.internal-link target=_blank}.

### Declare a *path parameter*

Then create a *path parameter* with a type annotation using the enum class you created (`ModelName`):

```Python hl_lines="16"

from typing import Optional

from fastapi.security.base import SecurityBase
from starlette.exceptions import HTTPException

Note that the `TestClient` receives data that can be converted to JSON, not Pydantic models.

If you have a Pydantic model in your test and you want to send its data to the application during testing, you can use the `jsonable_encoder` described in [JSON Compatible Encoder](encoder.md){.internal-link target=_blank}.
