############## <Fichero models

This is an auto-generated Django model module.

You'll have to do the following manually to clean this up:

* Rearrange models' order

* Make sure each model has one field with primary_key=True

* Make sure each ForeignKey and OneToOneField has on_delete set to the desired behavior

* Remove managed = False lines if you wish to allow Django to create, modify, and delete the table

Feel free to rename the models, but don't rename db_table values or field names.

No se si tendrá algo que ver pero la base de datos no es exactamente igual que la del curso, contiene muchas mas tablas. Entiendo que no debería afectar pero, por si acaso. Gracias
