@api.one

def bid_confirm(self):

    date = time.strftime("%Y-%m-%d") 

    auc = self.env['auction'].search([('auction_id','=',self.auc_id)])

     res = self.env['confirm.auction'].create({

                 'conf_auc_id':auc.id,

                 'product_id':self.product_id,

                 'customer_auc_id.id':self.write_uid.id,

                 'date_bid':date,

                 'amt_bid':self.amount_auc

    })

and if i remove id [ 'customer_auc_id':self.write_uid.id,  ]  so it is assign [  _unknown ,1 ]

i want to store customer name in m2o field customer_auc_id but it's not assigning correctly.

how to solve this issue?
