## Forbid Extra Form Fields { #forbid-extra-form-fields }

In some special use cases (probably not very common), you might want to **restrict** the form fields to only those declared in the Pydantic model. And **forbid** any **extra** fields.

/// note

This is supported since FastAPI version `0.114.0`. 🤓

## Pydantic 모델을 사용한 폼

**폼 필드**로 받고 싶은 필드를 **Pydantic 모델**로 선언한 다음, 매개변수를 `Form`으로 선언하면 됩니다:

{* ../../docs_src/request_form_models/tutorial001_an_py39.py hl[9:11,15] *}

**FastAPI**는 요청에서 받은 **폼 데이터**에서 **각 필드**에 대한 데이터를 **추출**하고 정의한 Pydantic 모델을 줍니다.

## 문서 확인하기

문서 UI `/docs`에서 확인할 수 있습니다:

## 추가 폼 필드 금지하기

# Моделі форм (Form Models)

У FastAPI Ви можете використовувати **Pydantic-моделі** для оголошення **полів форми**.

Щоб використовувати форми, спочатку встановіть <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">python-multipart</a>.

## Modelos Pydantic para Formulários

Você precisa apenas declarar um **modelo Pydantic** com os campos que deseja receber como **campos de formulários**, e então declarar o parâmetro como um `Form`:

{* ../../docs_src/request_form_models/tutorial001_an_py39.py hl[9:11,15] *}

function(){"function"==typeof b.onModulesLoaded&&b.onModulesLoaded();var c="string"==typeof b.form?a(b.form):b.form;a.formUtils.$win.trigger("validatorsLoaded",[c,b])})}}(a),function(a,b){"use strict";var c=a(b);a.formUtils=a.extend(a.formUtils||{},{$win:c,defaultConfig:function(){return{ignore:[],errorElementClass:"error",successElementClass:"valid",borderColorOnError:"#b94a48",errorMessageClass:"form-error",validationRuleAttribute:"data-validation",validationErrorMsgAttribute:"data-validation-...

/// info | Informação

Para enviar dados, você deve usar utilizar um dos métodos: `POST` (Mais comum), `PUT`, `DELETE` ou `PATCH`.

Enviar um corpo em uma requisição `GET` não tem um comportamento definido nas especificações, porém é suportado pelo FastAPI, apenas para casos de uso bem complexos/extremos.
