Add a computed One2many field to your model that references the generic.attachment model. This single field handles all file uploads automatically.

            from odoo import fields, models, api

            class SaleOrder(models.Model):
                _inherit = 'sale.order'
                
                generic_attachment_ids = fields.One2many(
                    'generic.attachment',
                    compute='_compute_generic_attachments',
                    inverse='_inverse_generic_attachments',
                    string='Attachments'
                )
                
                
                def _compute_generic_attachments(self):
                    for record in self:
                        attachments = self.env['generic.attachment'].search([
                            ('res_model', '=', self._name),
                            ('res_id', '=', record.id)
                        ])
                        record.generic_attachment_ids = attachments
                
                def _inverse_generic_attachments(self):
                    """Handle writes from the widget"""
                    pass
        

Use the multi_binary_dropzone widget on your One2many field in the form view. The widget automatically handles file uploads, downloads, and deletions.
