If a client tries to send some extra data, they will receive an **error** response.

For example, if the client tries to send the form fields:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

They will receive an error response telling them that the field `extra` is not allowed:

Pydantic의 모델 구성을 사용하여 추가(`extra`) 필드를 금지(`forbid`)할 수 있습니다:

{* ../../docs_src/request_form_models/tutorial002_an_py39.py hl[12] *}

클라이언트가 추가 데이터를 보내려고 하면 **오류** 응답을 받게 됩니다.

예를 들어, 클라이언트가 폼 필드를 보내려고 하면:

* `username`: `Rick`
* `password`: `Portal Gun`
* `extra`: `Mr. Poopybutthole`

`extra` 필드가 허용되지 않는다는 오류 응답을 받게 됩니다:

```json

            "type": "extra_forbidden",
