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 payment that are register throught the wizard then after the approval it should called back the initial method on the wizard(thats why i need to store id)

I have tried several ways to link the both model throught the fields payment_id in account.register.payment model and related_payment_id in account.payment but it still giving the "self_id" in this _unknow(actual_id,)
