            ),
        ] = _Unset,
        openapi_examples: Optional[Dict[str, Example]] = None,

因此在创建时也应当有一个`password`属性。

但是为了安全起见，`password`不会出现在其他同类 Pydantic*模型*中，例如用户请求时不应该从 API 返回响应中包含它。

하지만 지금은 FastAPI 0.99.0 및 이후 버전에서는 JSON 스키마 2020-12를 사용하는 OpenAPI 3.1.0과 Swagger UI 5.0.0 및 이후 버전을 사용하며, 모든 것이 더 일관성을 띄고 예시는 JSON 스키마에 포함됩니다.

### Swagger UI와 OpenAPI-특화 `examples`

현재 (2023-08-26), Swagger UI가 다중 JSON 스키마 예시를 지원하지 않으며, 사용자는 다중 예시를 문서에 표시하는 방법이 없었습니다.

## `Union` или `anyOf`

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

* **Document** the parameter in the OpenAPI schema *path operation* (so it will show up in the **automatic docs UI**)

## Alternative (old) `Query` as the default value

Previous versions of FastAPI (before <abbr title="before 2023-03">0.95.0</abbr>) required you to use `Query` as the default value of your parameter, instead of putting it in `Annotated`, there's a high chance that you will see code using it around, so I'll explain it to you.

Now let's see the file `sql_app/crud.py`.

### Create all the CRUD utils

Create all the same CRUD utils as in the SQLAlchemy tutorial, all the code is very similar:

```Python hl_lines="1  4-5  8-9  12-13  16-20  23-24  27-30"
{!../../../docs_src/sql_databases_peewee/sql_app/crud.py!}
```

There are some differences with the code for the SQLAlchemy tutorial.
