# Body - Fields { #body-fields }

The same way you can declare additional validation and metadata in *path operation function* parameters with `Query`, `Path` and `Body`, you can declare validation and metadata inside of Pydantic models using Pydantic's `Field`.

## Import `Field` { #import-field }

First, you have to import it:

{* ../../docs_src/body_fields/tutorial001_an_py310.py hl[4] *}

## Parâmetros de Arquivo com `UploadFile` { #file-parameters-with-uploadfile }

Defina um parâmetro de arquivo com um tipo de `UploadFile`:

{* ../../docs_src/request_files/tutorial001_an_py39.py hl[14] *}

Utilizar `UploadFile` tem várias vantagens sobre `bytes`:

* Você não precisa utilizar o `File()` no valor padrão do parâmetro.
* Ele utiliza um arquivo "spooled":

	NoPersistence bool `msg:"np"`
}

type CheckPartsHandlerParams struct {
	DiskID   string   `msg:"id"`
	Volume   string   `msg:"v"`

	FI       FileInfo `msg:"fi"`
}

// DeleteFileHandlerParams are parameters for DeleteFileHandler
type DeleteFileHandlerParams struct {
	DiskID   string        `msg:"id"`

        }
        return name;
    }
