### Pydantics `update`-Parameter verwenden { #using-pydantics-update-parameter }

Jetzt können Sie eine Kopie des existierenden Modells mittels `.model_copy()` erstellen, wobei Sie dem `update`-Parameter ein `dict` mit den zu ändernden Daten übergeben.

Wie in `stored_item_model.model_copy(update=update_data)`:

{* ../../docs_src/body_updates/tutorial002_py310.py hl[33] *}

{* ../../docs_src/body_updates/tutorial002_py310.py hl[32] *}

### Uso del parámetro `update` de Pydantic { #using-pydantics-update-parameter }

Ahora, puedes crear una copia del modelo existente usando `.model_copy()`, y pasar el parámetro `update` con un `dict` que contenga los datos a actualizar.

Como `stored_item_model.model_copy(update=update_data)`:

{* ../../docs_src/body_updates/tutorial002_py310.py hl[33] *}

	// should skip healing the disk
	SkipHealing bool

	// Active lifecycle, if any on the bucket
	lifeCycle *lifecycle.Lifecycle `msg:"-"`

	// optional updates channel.
	// If set updates will be sent regularly to this channel.
	// Will not be closed when returned.
	updates     chan<- dataUsageEntry `msg:"-"`
	replication replicationConfig     `msg:"-"`
}

func (e *dataUsageEntry) addSizes(summary sizeSummary) {

                                        <la:message key="labels.crud_button_back"/>
                                    </la:link>
                                    <button type="submit" class="btn btn-success" name="update"
                                            value="<la:message key="labels.crud_button_update" />">
                                        <i class="fa fa-pencil-alt" aria-hidden="true"></i>

        return new String[] { str };
    }

    protected LocalDateTime toLocalDateTime(Object value) {
        return DfTypeUtil.toLocalDateTime(value);
    }

    protected Date toDate(Object value) {
        return DfTypeUtil.toDate(value);
    }

    protected SearchHits getSearchHits(final SearchResponse response) {
        SearchHits hits = response.getHits();
        if (hits == null) {

{* ../../docs_src/body_updates/tutorial002_py310.py hl[32] *}

### Utiliser le paramètre `update` de Pydantic { #using-pydantics-update-parameter }

Vous pouvez maintenant créer une copie du modèle existant avec `.model_copy()`, et passer le paramètre `update` avec un `dict` contenant les données à mettre à jour.

Comme `stored_item_model.model_copy(update=update_data)` :

{* ../../docs_src/body_updates/tutorial002_py310.py hl[33] *}

					// to the end of the
					// corresponding DARE package
					lbPkgEndOffset := min(lbPartOffset-(lbPartOffset%pkgSz)+pkgSz, v)
					bytesToDrop := v - lbPkgEndOffset

					// Last segment to update `l`
					l += getEncSize(currentPartDareBytes - bytesToDrop)
					break
				}
			}

			cumulativeSum += v
			cumulativeEncSum += getEncSize(v)
		}
		return o, l, skip, sn, ps
	}
