### Den `response_model_exclude_unset`-Parameter verwenden { #use-the-response-model-exclude-unset-parameter }

Sie können den *Pfadoperation-Dekorator*-Parameter `response_model_exclude_unset=True` setzen:

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

* `headers` - Um dicionário `dict` de strings.
* `media_type` - Uma `str` informando o media type. E.g. `"text/html"`.

O FastAPI (Starlette, na verdade) irá incluir o cabeçalho Content-Length automaticamente. Ele também irá incluir o cabeçalho Content-Type, baseado no `media_type` e acrescentando uma codificação para tipos textuais.

### 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)`.

        includeList.add("https://example.com/.*");
        includeList.add("https://test.com/.*");
        service.addIncludeUrlFilter(sessionId, includeList);

        // Add exclude filters
        List<String> excludeList = new ArrayList<>();
        excludeList.add("https://example.com/admin/.*");
        excludeList.add("https://example.com/private/.*");

     * @return the converted EditBody
     */
    protected EditBody createEditBody(final ScheduledJob entity) {
        final EditBody body = new EditBody();
        copyBeanToBean(entity, body, op -> op.exclude(Constants.COMMON_CONVERSION_RULE));
        body.running = entity.isRunning();
        return body;
    }
