## Restrinja Parâmetros de Consulta Extras { #forbid-extra-query-parameters }

Em alguns casos especiais (provavelmente não muito comuns), você queira **restrinjir** os parâmetros de consulta que deseja receber.

Você pode usar a configuração do modelo Pydantic para `forbid` (proibir) qualquer campo `extra`:

## 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**.
