Isso é útil se você não souber os nomes de campo / atributo válidos (que seriam necessários para um modelo Pydantic) antecipadamente.

Neste caso, você pode usar `typing.Dict` (ou simplesmente dict no Python 3.9 e superior):

{* ../../docs_src/extra_models/tutorial005.py hl[1,8] *}

## Em resumo

Use vários modelos Pydantic e herde livremente para cada caso.

     *
     * @param documentList the list of documents returned by the search
     * @param allRecordCount the total number of records in the search result set
     * @param allRecordCountRelation the relation type for the total record count
     * @param queryTime the time taken to execute the search query in milliseconds
     * @param partialResults flag indicating whether the results are partial

     *
     * @param repositories The original repositories, may be {@code null}.
     * @return The effective repositories or {@code null} if the input was {@code null}.

    List<ArtifactRepository> getEffectiveRepositories(List<ArtifactRepository> repositories);

Esto puede ser muy útil para configurar **recursos** que necesitas usar para toda la app, y que son **compartidos** entre requests, y/o que necesitas **limpiar** después. Por ejemplo, un pool de conexiones a una base de datos, o cargando un modelo de machine learning compartido.

### Breve

Tiene **valores predeterminados** sensatos para todo, con configuraciones opcionales en todas partes. Todos los parámetros se pueden ajustar finamente para hacer lo que necesitas y para definir el API que necesitas.

Pero por defecto, todo **"simplemente funciona"**.
