RtAPI - PV of a Loan

[mustermeiszer]

Allow to retrieve the PV of a loan.
It is important that the now defining the value is optionally providable, to get a glimbs into the future. Past should be forbidden, as this is messy.

It's already done here: https://github.com/centrifuge/centrifuge-chain/blob/main/pallets/loans/src/entities/loans.rs#L529

@lemunozm but this is the lastly computed value, we would want the latest value available, or is the loans logic updating all loans when constructing the portfolio?

[lemunozm]

Yes, the current line above returns the present value computed just at the moment when it's retrieved. If you want the present value at the moment when the portfolio was updated, you can fetch then the PortfolioValuation type from the storage, which holds the values for all loans: https://github.com/centrifuge/centrifuge-chain/blob/main/pallets/loans/src/lib.rs#L1020

[mustermeiszer]

The API should give the PV of a loan at now() with this API. If possible.

Then, it's done in the first shared line, where the present value is computed with now()
