Good afternoon community, I have a problem since I am trying to calculate the total amount paid with a specific newspaper as cash but nothing returns.

this is my code:

class cierre_caja(models.Model): 

_name = 'cierre_caja.cierre_caja' 

_inherit='account.payment'

pagos_d = fields.Monetary(string="Pago",compute='valorespago')

@api.depends('amount','journal_id','move_id','name') 

def valorespago(self):

 pago = self.env['account.payment'] f

or record in self: 

payment_journal = 0 

pago_id = pago.search([('journal_id', '=', '7')]) 

if pago_id: 

for pago in pago_id: 

payment_journal += pago.amount r

ecord.pago_id = record.balance + payment_journal
