* Un parámetro de query `limit` que es un `int`, con un valor por defecto de `100`.

En ambos casos, los datos serán convertidos, validados, documentados en el esquema de OpenAPI, etc.

## Úsalo

Ahora puedes declarar tu dependencia usando esta clase.

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

Nuevamente, haciendo solo esa declaración, con **FastAPI** obtienes:

* Soporte de editor (autocompletado, etc.), incluso para modelos anidados
* Conversión de datos
* Validación de datos
* Documentación automática

## Tipos especiales y validación

Además de tipos singulares normales como `str`, `int`, `float`, etc., puedes usar tipos singulares más complejos que heredan de `str`.

#!/bin/bash

cd `dirname $0`
. ./_project.sh

FIRST_ARG=$1
SECOND_ARG=$2

sh $DBFLUTE_HOME/etc/cmd/_df-manage.sh $MY_PROPERTIES_PATH $FIRST_ARG $SECOND_ARG
taskReturnCode=$?

if [ $taskReturnCode -ne 0 ];then
  exit $taskReturnCode;

This client could be a browser with a frontend, a code from someone else, an IoT device, etc.

You could need to tell the client that:

* The client doesn't have enough privileges for that operation.
* The client doesn't have access to that resource.
* The item the client was trying to access doesn't exist.
* etc.

In these cases, you would normally return an **HTTP status code** in the range of **400** (from 400 to 499).

* A `skip` query parameter that is an `int`, with a default of `0`.
* A `limit` query parameter that is an `int`, with a default of `100`.

In both cases the data will be converted, validated, documented on the OpenAPI schema, etc.

## Use it { #use-it }

Now you can declare your dependency using this class.

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

Este código es algo que puedes usar realmente en tu aplicación, guardar los hashes de las contraseñas en tu base de datos, etc.

Vamos a empezar desde donde lo dejamos en el capítulo anterior e incrementarlo.

## Acerca de JWT

JWT significa "JSON Web Tokens".

E esses modelos estão compartilhando muitos dos dados e duplicando nomes e tipos de atributos.

Nós poderíamos fazer melhor.

Podemos declarar um modelo `UserBase` que serve como base para nossos outros modelos. E então podemos fazer subclasses desse modelo que herdam seus atributos (declarações de tipo, validação, etc.).
