# Modelos Extra { #extra-models }

Continuando con el ejemplo anterior, será común tener más de un modelo relacionado.

Esto es especialmente el caso para los modelos de usuario, porque:

* El **modelo de entrada** necesita poder tener una contraseña.
* El **modelo de salida** no debería tener una contraseña.
* El **modelo de base de datos** probablemente necesitaría tener una contraseña hasheada.

# Aplicaciones más grandes - Múltiples archivos { #bigger-applications-multiple-files }

Si estás construyendo una aplicación o una API web, rara vez podrás poner todo en un solo archivo.

**FastAPI** proporciona una herramienta conveniente para estructurar tu aplicación manteniendo toda la flexibilidad.
