Hi,

How to display an account bank number(acc number) in the form of payment using the field partner_id?

----------------------------------------------

python  code:

class account_payment(models.Model):   

 _inherit = "account.payment"   

 _description = "Payments"

partner_id   = fields.Many2one('res.partner')

bank_account_id = fields.Many2one(compute='_compute_bank_account', string='Bank Account',readonly=True)

@api.multi
def _compute_bank_account(self):

     if self.partner_id:                

            self.env.cr.execute('select acc_number from res_partner_bank where partner_id = %s ', (self.partner_id.id))

 I want the account number displayed as soon as the partner_id is selected.

 I don't get the output I want from the above code  .

 please guide me  .

Thanks.
