Dear all

My codes are, how to write this inverse function so the user can edit the field 'lot_ids'. thanks

lot_ids = fields.Many2many('stock.lot', string='Lots/Serials', compute='_get_lot_name',
                           readonly=False, domain="[('product_id', '=', product_id)]", store=True)
lot_name = fields.Char(string='Lots/Serials', compute='_get_lot_name', readonly=False, store=True)
has_lot_id = fields.Boolean(string='Has Lot ids', compute="_compute_has_lot_id", store=True)

@api.depends('has_lot_id', 'picking_id','picking_id.move_line_ids')
def _get_lot_name(self):
    for rec in self:
        if rec.has_lot_id and rec.picking_id:
            stock_move_lines = self.env['stock.move.line'].sudo().search([('picking_id', '=', rec.picking_id.id)])
            # print('stock_move_lines', stock_move_lines, stock_move_lines.mapped('lot_id'),
            #       stock_move_lines.mapped('lot_name'))
            if all(value is not False for value in stock_move_lines.mapped('lot_name')):
                # Get the lot names from the stock move lines, filtering out any non-string values (e.g.,False)
                # print('stock_move_lines.mapped name', stock_move_lines.mapped('lot_name'))
                lot_names = [name for name in stock_move_lines.mapped('lot_name') if isinstance(name, str)]
                rec.lot_name = ', '.join(lot_names) if lot_names else ''
            elif len(stock_move_lines.mapped('lot_id').mapped('id')):
                # print('stock_move_lines.mapped', stock_move_lines.mapped('lot_id').mapped('id'))
                lot_ids = stock_move_lines.mapped('lot_id').ids
                rec.lot_ids = self.env['stock.lot'].browse(lot_ids)
