sails.js - How to code composite keys into SailsJS -

-

i have question sailsjs. research i've done have yet find substantial amount of examples or explanation composite keys in sailsjs. have done have learned absolutely have form of workaround in order composite keys work in sailsjs however, don't understand or follow small examples have found online. if take time out of day , explain them or explicitly give example i'd appreciative.

this possibly asked here: sails.js composite unique field

and issue conversation on git - best done in actual db , not live in code...if cannot done whatever use case warrants departure of best practice, code whatever works best needs...it's not "wrong" answer have needs drive edges :)

if have specific question feel free edit question , perhaps better explanation of composite keys can provided.
