### Использование параметра `exclude_unset` в Pydantic { #using-pydantics-exclude-unset-parameter }

Если необходимо выполнить частичное обновление, то очень полезно использовать параметр `exclude_unset` в методе `.model_dump()` модели Pydantic.

Например, `item.model_dump(exclude_unset=True)`.

### Используйте параметр `response_model_exclude_unset` { #use-the-response-model-exclude-unset-parameter }

Вы можете установить у *декоратора операции пути* параметр `response_model_exclude_unset=True`:

{* ../../docs_src/response_model/tutorial004_py310.py hl[22] *}

				// and should never happen - however it has
				// been seen recently due to hardware issues
				// causes Reads() to go slower than Writes().
				//
				// Send such results anyways as this shall
				// expose a problem underneath.
				if totalPut > throughputHighestPut {
					throughputHighestResults = results
					throughputHighestPut = totalPut
					// let the client see lower value as well

        assertNotNull(resp, "Response should not be null after init");
        // getResponse should now return the same instance
        assertSame(resp, req.getResponse(), "getResponse should expose the initialized response");
    }

    @Test
    @DisplayName("getResponse before initResponse returns null")
    void getResponseInitiallyNull() {
        SmbComNTCreateAndX req = createRequest(0, 0);

     */
    protected EditBody createEditBody(final FileConfig entity) {
        final EditBody body = new EditBody();
        copyBeanToBean(entity, body, copyOp -> {
            copyOp.excludeNull();
            copyOp.exclude(Constants.PERMISSIONS, Constants.VIRTUAL_HOSTS);
        });
        final PermissionHelper permissionHelper = ComponentUtil.getPermissionHelper();

      </plugin>
      <plugin>
        <artifactId>maven-javadoc-plugin</artifactId>
        <configuration>

          <!-- excludePackageNames requires specification of packages separately from "all subpackages".

### Usando o parâmetro `exclude_unset` do Pydantic { #using-pydantics-exclude-unset-parameter }

Se você quiser receber atualizações parciais, é muito útil usar o parâmetro `exclude_unset` no método `.model_dump()` do modelo do Pydantic.

Como `item.model_dump(exclude_unset=True)`.

Dans ce cas, votre `Dockerfile` pourrait ressembler à ceci :

```Dockerfile
FROM python:3.7

RUN pip install fastapi uvicorn

EXPOSE 80

COPY ./app /app

CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "80"]
```

## Créer le code **FastAPI**.

* Créer un répertoire `app` et y entrer.
* Créez un fichier `main.py` avec :
