## Criar um modelo de usuário { #create-a-user-model }

Primeiro, vamos criar um modelo de usuário com Pydantic.

Da mesma forma que usamos o Pydantic para declarar corpos, podemos usá-lo em qualquer outro lugar:

## Criar uma dependência `get_current_user` { #create-a-get-current-user-dependency }

  /**

   * startNodes}.

      this.gen = gen;
    }

    @Override
    public SampleElements<E> samples() {
      return gen.samples();
    }

    @Override
    public Collection<E> create(Object... elements) {
      return SerializableTester.reserialize(gen.create(elements));
    }

    @Override
    public E[] createArray(int length) {
      return gen.createArray(length);
    }

    @Override

   * use E... or E[] as a parameter type, but this doesn't seem to work because Java creates an
   * array of the erased type.
   */
  T create(Object... elements);

  /**
   * Helper method to create an array of the appropriate type used by this generator. The returned
   * array will contain only nulls.
   */
  E[] createArray(int length);

  /**

    collection = getSubjectGenerator().create(array);

@ExtendWith(MockitoExtension.class)

    private static final short SMB2_TREE_DISCONNECT = 0x0004;

    @Test
    @DisplayName("Should create request with correct command type")
    void testConstructorSetsCorrectCommand() throws Exception {
        // Given
        Configuration mockConfig = mock(Configuration.class);

        // When

	AmzMetaName = "X-Amz-Meta-Name"

	// Delete special flag to force delete a bucket or a prefix
	MinIOForceDelete = "x-minio-force-delete"

	// Create special flag to force create a bucket
	MinIOForceCreate = "x-minio-force-create"

	// Header indicates if the mtime should be preserved by client
	MinIOSourceMTime = "x-minio-source-mtime"

	// Header indicates if the etag should be preserved by client

Let's see a very simple example. It will be so simple that it is not very useful, for now.

But this way we can focus on how the **Dependency Injection** system works.

### Create a dependency, or "dependable" { #create-a-dependency-or-dependable }

Let's first focus on the dependency.

It is just a function that can take all the same parameters that a *path operation function* can take:

            task.getDestFile().convention(dslReference.getStagingRoot().file("index.xml"));
        });

        Configuration userGuideTask = project.getConfigurations().create("userGuideTask");
        Configuration userGuideStyleSheetConf = project.getConfigurations().create("userGuideStyleSheets");

        TaskProvider<Docbook2Xhtml> dslHtml = tasks.register("dslHtml", Docbook2Xhtml.class, task -> {
            task.setGroup("documentation");
