values = {

            'name': 'sample.txt',

            'datas_fname': 'sample.txt',

            'res_model': 'ir.ui.view',

            'res_id': False,

            'type': 'binary',

            'public': True,

            'datas': file_data.encode('utf8').encode('base64'),

        }

All the data are in one line even when I put \n on each line. someone suggested to decode it but I don't know how to decode.
