Sie können `examples` („Beispiele“) für ein Pydantic-Modell deklarieren, welche dem generierten JSON-Schema hinzugefügt werden.

=== "Python 3.10+ Pydantic v2"

    ```Python hl_lines="13-24"
    {!> ../../../docs_src/schema_extra_example/tutorial001_py310.py!}
    ```

=== "Python 3.10+ Pydantic v1"

    ```Python hl_lines="13-23"
    {!> ../../../docs_src/schema_extra_example/tutorial001_py310_pv1.py!}

## Extra JSON Schema data in Pydantic models

You can declare `examples` for a Pydantic model that will be added to the generated JSON Schema.

=== "Python 3.10+ Pydantic v2"

    ```Python hl_lines="13-24"
    {!> ../../../docs_src/schema_extra_example/tutorial001_py310.py!}
    ```

=== "Python 3.10+ Pydantic v1"

    ```Python hl_lines="13-23"
    {!> ../../../docs_src/schema_extra_example/tutorial001_py310_pv1.py!}

{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Modify the OpenAPI schema

Now you can add the ReDoc extension, adding a custom `x-logo` to the `info` "object" in the OpenAPI schema:

```Python hl_lines="22-24"
{!../../../docs_src/extending_openapi/tutorial001.py!}
```

### Cache the OpenAPI schema

You can use the property `.openapi_schema` as a "cache", to store your generated schema.

대신 평문 비밀번호로 입력 모델을 만들고 해당 비밀번호 없이 출력 모델을 만들 수 있습니다:

```Python hl_lines="9  11  16"

```

여기서 *경로 작동 함수*가 비밀번호를 포함하는 동일한 입력 사용자를 반환할지라도:

```Python hl_lines="24"
{!../../../docs_src/response_model/tutorial003.py!}
```

...`response_model`을 `UserOut` 모델로 선언했기 때문에 비밀번호를 포함하지 않습니다:

```Python hl_lines="22"

        Prefer to use the `Annotated` version if possible.

## `Union` или `anyOf`

Вы можете определить ответ как `Union` из двух типов. Это означает, что ответ должен соответствовать одному из них.

## `Union` or `anyOf`

You can declare a response to be the `Union` of two types, that means, that the response would be any of the two.
