В данном примере она преобразует Pydantic-модель в `dict`, а `datetime` - в `str`.

Результатом её вызова является объект, который может быть закодирован с помощью функции из стандартной библиотеки Python – [`json.dumps()`](https://docs.python.org/3/library/json.html#json.dumps).

Далі це можна використовувати так:

```Python

from pydantic import BaseModel

    description: str | None = None
    price: float
    tax: float | None = None

@app.post("/items/")
async def create_item(item: Item):
