## Cookies con un Modelo de Pydantic { #cookies-with-a-pydantic-model }

Declara los parámetros de **cookie** que necesites en un **modelo de Pydantic**, y luego declara el parámetro como `Cookie`:

{* ../../docs_src/cookie_param_models/tutorial001_an_py310.py hl[9:12,16] *}

**FastAPI** **extraerá** los datos para **cada campo** de las **cookies** recibidas en el request y te entregará el modelo de Pydantic que definiste.

## Criar o App com um Único Modelo { #create-the-app-with-a-single-model }

Vamos criar a primeira versão mais simples do app com um único modelo **SQLModel**.

Depois, vamos melhorá-lo aumentando a segurança e versatilidade com **múltiplos modelos** abaixo. 🤓

### Criar Modelos { #create-models }

Importe o `SQLModel` e crie um modelo de banco de dados:

	// ErrPrimaryKeyRequired primary keys required
	ErrPrimaryKeyRequired = errors.New("primary key required")
	// ErrModelValueRequired model value required
	ErrModelValueRequired = errors.New("model value required")
	// ErrModelAccessibleFieldsRequired model accessible fields required
	ErrModelAccessibleFieldsRequired = errors.New("model accessible fields required")
	// ErrSubQueryRequired sub query required
	ErrSubQueryRequired = errors.New("sub query required")

### Входная модель в документации { #input-model-in-docs }

В документации это видно: у поля `description` нет **красной звёздочки** — оно не отмечено как обязательное:

### Модель для выхода { #model-for-output }
