Clojurians Log v2

I want to change a route to support a composite lookup key coming from the route's URL rather than having the ident up front. Is the right place to handle this within the component's :will-enter? I'm trying to do that but route-deferred expects an ident, which I won't have until after a DB query based on the provided composite key.

getting
