Ten en cuenta que los dataclasses no pueden hacer todo lo que los modelos de Pydantic pueden hacer.

Así que, podrías necesitar seguir usando modelos de Pydantic.

Pero si tienes un montón de dataclasses por ahí, este es un buen truco para usarlos para potenciar una API web usando FastAPI. 🤓

## Dataclasses en `response_model`

También puedes usar `dataclasses` en el parámetro `response_model`:

     * This method applies various filter conditions based on the pager parameters
     * including name, paths, and description filters with wildcard and phrase matching.
     *
     * @param cb the condition bean for building the database query
     * @param fileConfigPager the pager containing search filter criteria
     */
    protected void setupListCondition(final FileConfigCB cb, final FileConfigPager fileConfigPager) {

 * or implied. See the License for the specific language governing permissions and limitations under
