## Arquivo de upload opcional

Você pode definir um arquivo como opcional utilizando as anotações de tipo padrão e definindo o valor padrão como `None`:

//// tab | Python 3.10+

```Python hl_lines="9  17"

    public HtmlResponse back() {
        saveToken();
        return asHtml(path_AdminDesign_AdminDesignJsp).useForm(DesignForm.class);
    }

    @Execute
    @Secured({ ROLE })
    public HtmlResponse upload(final UploadForm form) {
        validate(form, messages -> {}, () -> asListHtml(form));
        verifyToken(this::asListHtml);
        final String uploadedFileName = form.designFile.getFileName();

			DataMovement: true,
			SrcPoolIdx:   poolIdx,
		})
		if err != nil {
			return fmt.Errorf("rebalanceObject: NewMultipartUpload() %w", err)
		}
		defer z.AbortMultipartUpload(ctx, bucket, oi.Name, res.UploadID, ObjectOptions{NoAuditLog: true})

		parts := make([]CompletePart, len(oi.Parts))
		for i, part := range oi.Parts {
			hr, err := hash.NewReader(ctx, io.LimitReader(gr, part.Size), part.Size, "", "", part.ActualSize)

```

And then, right after the `yield`, we unload the model. This code will be executed **after** the application **finishes handling requests**, right before the *shutdown*. This could, for example, release resources like memory or a GPU.
