## Proibir Campos Extras de Formulários { #forbid-extra-form-fields }

Em alguns casos de uso especiais (provavelmente não muito comum), você pode desejar **restringir** os campos do formulário para aceitar apenas os declarados no modelo Pydantic. E **proibir** qualquer campo **extra**.

/// note | Nota

Isso é suportado deste a versão `0.114.0` do FastAPI. 🤓

Теперь давайте посмотрим, как можно использовать это для возврата пользовательского ответа.

Допустим, вы хотите вернуть ответ в формате <a href="https://en.wikipedia.org/wiki/XML" class="external-link" target="_blank">XML</a>.

Вы можете поместить ваш XML-контент в строку, поместить её в `Response` и вернуть:

{* ../../docs_src/response_directly/tutorial002_py39.py hl[1,18] *}

You declare the "shape" of the data as classes with attributes.

And each attribute has a type.
