 def generate_pdf_csv(self):
        file_name = self.pdf_name
        attachment_dict = {
                            'name': file_name,
                            'datas': self.file_upload_pdf,
                            'datas_fname': file_name,
                            'res_model': self._name,
                            'res_id': self.id,
                            'type': 'binary',
                        }
        attachment_id = 
        self.env['ir.attachment'].sudo().create(attachment_dict)
        temp_dir = tempfile.gettempdir()
        temp_path = os.path.join(temp_dir, file_name)
        pdf_file = temp_path
        tables = camelot.read_pdf(pdf_file, pages='all')
        csv_file = 'FOLLL123.csv'
        tables.export(csv_file, f='csv', compress=True)
        tables[0].to_csv(csv_file)
