I'm working with Odoo 16 and have encountered a problem with linking two models and handling _unknown values. Specifically, I have two models: nkap_custom_paiement and account.payment.register. The former is a custom model inheriting from account.payment, and the latter is a TransientModel used for payment registration.
Models Overview:
nkap_custom_paiement (Inheriting account.payment)
Has a field related_payment_id that links to account.register.payment. Handles payment approvals and has methods like action_cashier_approval to perform actions on linked payments.
CustomPaymentRegister (Inheriting account.payment.register)
Handles the creation of account.payment records and sets the related_payment_id to link back to the wizard.
I am trying to add an approval process to the payments that are registered through the wizard. After the approval, it should call back the initial method on the wizard (that's why I need to store id)

I have tried several ways to link the both model through the field payment_id in account.register.payment model and related_payment_id in account.payment, but it is still giving the self_id in this _unknown(actual_id,)
That's just a typo on your class nkap_custom_paiement. The comodel for the field related_payment_id is account.payment.register and not account.register.payment. If Odoo can't find the related model on e.g. a Many2one field in its model pool, it will fill it with model name _unknown (click)
def setup_nonrelated(self, model):
super().setup_nonrelated(model)
if self.comodel_name not in model.pool:
_logger.warning("Field %s with unknown comodel_name %r", self, self.comodel_name)
self.comodel_name = '_unknown'
