## Add `dependencies` to the *path operation decorator* { #add-dependencies-to-the-path-operation-decorator }

The *path operation decorator* receives an optional argument `dependencies`.

It should be a `list` of `Depends()`:

{* ../../docs_src/dependencies/tutorial006_an_py39.py hl[19] *}

Portanto, se você quiser receber atualizações parciais que possam omitir todos os atributos, precisará ter um modelo com todos os atributos marcados como opcionais (com valores padrão ou `None`).

Para distinguir os modelos com todos os valores opcionais para **atualizações** e modelos com valores obrigatórios para **criação**, você pode usar as ideias descritas em [Modelos Adicionais](extra-models.md){.internal-link target=_blank}.

        for (Object aSet : set) {
            Artifact artifact = (Artifact) aSet;
            System.out.println("Artifact: " + artifact.getDependencyConflictId() + " " + artifact.getVersion()
                    + " Optional=" + (artifact.isOptional() ? "true" : "false"));
            assertTrue(
                    artifact.getVersion().equals("1.0"), "Incorrect version for " + artifact.getDependencyConflictId());
        }
    }

     *
     * @param tc
     *            context to use
     * @param type2
     *            The Type-2 message which this represents a response to.
     * @param targetName
     *            SPN of the target system, optional
     * @param password
     *            The password to use when constructing the response.
     * @param domain
     *            The domain in which the user has an account.
     * @param user

E com qualquer retorno que você desejar.

Neste caso, a dependência espera por:

* Um parâmetro de consulta opcional `q` do tipo `str`.
* Um parâmetro de consulta opcional `skip` do tipo `int`, e igual a `0` por padrão.
* Um parâmetro de consulta opcional `limit` do tipo `int`, e igual a `100` por padrão.

E então retorna um `dict` contendo esses valores.

MinIO implements an S3 extension to the [PostUpload](https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPOST.html) where in a special fan-out list is sent along with the TSB's for MinIO make multiple uploads from a single source stream. Optionally supports custom metadata, tags and other retention settings. All objects are also readable independently once upload is completed via the regular S3 [GetObject](https://docs.aws.amazon.com/AmazonS3/latest/API/API_GetObject.html) API.
