I'm using this code to get the order lines of a sale order
    sale_order_line_ids = fields.Many2many("sale.order.line","helpdesk_ticket_ids", compute="_compute_sale_order_lines", copy=True, auto_join=True)

    @api.depends("sale_order_id")    def _compute_sale_order_lines(self):        for record in self:            if record.sale_order_id:                record.write({"sale_order_line_ids": [(6, 0, record.sale_order_id.order_line.ids)]}) 

but if they are used in a view they cant be edited.
does anybody know what can be done to make them editable?
