I have a situation where an instance method pulls out a selection from a
set of associated objects. Sometimes when this is called the associated
objects have been eager loaded, in which case it makes most sense to use
.select to pull the ones i want from the already-loaded collection.
Other times the associated objects have not been eager loaded, and it
makes most sense to use association.find to get the ones i want.
My question is this: can i tell if the associated objects have been
eager loaded already, so i can choose which approach to take? Or, even
better, is there a single approach where rails will know whether to load
them again or not?
thanks, max
