여기 이를 위한 몇가지 방식이 있습니다.

## Pydantic 모델 속 추가 JSON 스키마 데이터

생성된 JSON 스키마에 추가될 Pydantic 모델을 위한 `examples`을 선언할 수 있습니다.

//// tab | Pydantic v2

{* ../../docs_src/schema_extra_example/tutorial001_py310.py hl[13:24] *}

////

//// tab | Pydantic v1

{* ../../docs_src/schema_extra_example/tutorial001_pv1_py310.py hl[13:23] *}

////

추가 정보는 있는 그대로 해당 모델의 **JSON 스키마** 결과에 추가되고, API 문서에서 사용합니다.

This part is pretty normal, most of the code is probably already familiar to you:

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[7:11,34:51] *}

/// tip

The `callback_url` query parameter uses a Pydantic <a href="https://docs.pydantic.dev/latest/api/networks/" class="external-link" target="_blank">Url</a> type.

Essa parte é bastante normal, a maior parte do código provavelmente já é familiar para você:

O parâmetro de consulta `callback_url` usa um tipo Pydantic <a href="https://docs.pydantic.dev/latest/api/networks/" class="external-link" target="_blank">Url</a>.

@pytest.fixture(

    params=[

    client = TestClient(mod.app)

Для этого можно использовать функцию `jsonable_encoder`.

Она принимает объект, например, Pydantic-модель, и возвращает его версию, совместимую с JSON:

{* ../../docs_src/encoder/tutorial001_py310.py hl[4,21] *}

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