Resolved. Create a method in the model account.move, inheriting the class

def payments_create(self):
invoice_object = self
cliente = self.env['res.partner'].search([('id','=', self.partner_id.id)])
ctx = dict(
active_ids=invoice_object.ids, # Use ids and not id (it has to be a list)
active_model='account.move',
)
values = {
'payment_type': 'inbound',
'partner_type': 'customer',
'partner_id': self.partner_id.id,
'payment_method_id': 1,
'amount': self.amount_total,
'payment_date': self.date,
'currency_id': 1,
'journal_id': 14,
'communication': self.name,
}
wizard = self.env['account.payment.register'].with_context(ctx).create(values)
wizard._create_payments()
