Und wenn Sie alle verfügbaren Schemas (JSON-Schemas) in OpenAPI überprüfen, werden Sie feststellen, dass es zwei gibt, ein `Item-Input` und ein `Item-Output`.

Für `Item-Input` ist `description` **nicht erforderlich**, es hat kein rotes Sternchen.

Aber für `Item-Output` ist `description` **erforderlich**, es hat ein rotes Sternchen.

## Alias para parámetros { #alias-parameters }

Imagina que quieres que el parámetro sea `item-query`.

Como en:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Pero `item-query` no es un nombre de variable válido en Python.

Lo más cercano sería `item_query`.

Pero aún necesitas que sea exactamente `item-query`...
