We could do better.

We can declare a `UserBase` model that serves as a base for our other models. And then we can make subclasses of that model that inherit its attributes (type declarations, validation, etc).

All the data conversion, validation, documentation, etc. will still work as normally.

That way, we can declare just the differences between the models (with plaintext `password`, with `hashed_password` and without password):

import org.opensearch.index.query.QueryBuilder;
import org.opensearch.index.query.QueryBuilders;
import org.opensearch.search.sort.SortOrder;

/**
 * Command class for handling term query execution and conversion.
 * This class processes Lucene TermQuery objects and converts them to OpenSearch QueryBuilder instances.
 */
public class TermQueryCommand extends QueryCommand {

En este caso, `item_id` se declara como un `int`.

/// check | Revisa

Esto te dará soporte del editor dentro de tu función, con chequeo de errores, autocompletado, etc.

## Conversión de datos

Si ejecutas este ejemplo y abres tu navegador en <a href="http://127.0.0.1:8000/items/3" class="external-link" target="_blank">http://127.0.0.1:8000/items/3</a>, verás un response de:

```JSON
{"item_id":3}

Eso significa que cualquier valor leído en Python desde una variable de entorno será un `str`, y cualquier conversión a un tipo diferente o cualquier validación tiene que hacerse en código.
