.lazy_relation(id_method, klass_name, cache) ⇒ Object

Returns a Batchloader for a given class to avoid N+1 queries.

Since ActionLogs are related to many different resources, loading a collection of them would trigger a lot of N+1 queries. We are using BatchLoader to accumulate and group all the resource by their class and only loading them when it is necessary.
