I need to update a field value in a field in another model in odoo15

Question

I need to update the Margin field which is a one2many field of SaleOrderLine to field margin in another model StockMove. How can we achieve it in Odoo 15
class SaleOrderLine(models.Model):
_inherit = 'sale.order.line'
Margin = fields.Float( string = "Margin" )
@api.model
def  action_confirm ( self ):
record = self .env[ 'stock.move' ].update({ 'Margin' : self .Margin})
print (record)
return  super (SaleOrderLine ,  self ).action_confirm( self )

class StockMove(models.Model):
_inherit = 'stock.m

Sale Order line have one2many relation with stock.move. So, if you want to update margin field of all moves related with line the try below code.
class SaleOrder(models.Model):
_inherit = 'sale.order'
def action_confirm(self):
for line in self.order_line:
for move in line.move_ids:
move.write({'Margin':line.Margin})
return super(SaleOrder, self).action_confirm(self)
