`Query`, `Path` ve `Body` ile *path operation function* parametrelerinde ek doğrulama ve metadata tanımlayabildiğiniz gibi, Pydantic modellerinin içinde de Pydantic'in `Field`'ını kullanarak doğrulama ve metadata tanımlayabilirsiniz.

## `Field`'ı import edin { #import-field }

Önce import etmeniz gerekir:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}

/// warning | Uyarı

			if !ok {
				if preloadFields := strings.Split(association, "."); len(preloadFields) > 1 {
					relationships := &db.Statement.Schema.Relationships
					for _, field := range preloadFields {
						var ok bool
						relation, ok = relationships.Relations[field]
						if ok {
							relationships = &relation.FieldSchema.Relationships
						} else {
							db.AddError(fmt.Errorf("relation %s not found", association))

# Тіло — Поля { #body-fields }

Так само як ви можете оголошувати додаткову валідацію та метадані в параметрах *функції операції шляху* за допомогою `Query`, `Path` та `Body`, ви можете оголошувати валідацію та метадані всередині моделей Pydantic, використовуючи `Field` від Pydantic.

## Імпорт `Field` { #import-field }

Спочатку вам потрібно імпортувати це:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}


/// warning | Попередження

# Corpo - Campos { #body-fields }

Da mesma forma que você pode declarar validações adicionais e metadados nos parâmetros de uma *função de operação de rota* com `Query`, `Path` e `Body`, você pode declarar validações e metadados dentro de modelos do Pydantic usando `Field` do Pydantic.

## Importe `Field` { #import-field }

Primeiro, você tem que importá-lo:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}
