Let’s say I have Departments, which have many Persons , which have many
I can fetch Departments and eagerly load their Persons, with :include=>
in the find statement.
But what if I want to eagerly load all the Persons, and all of the
Persons’ Pets, in, if not one single db trip, then maybe in two? In as
few as possible.
I don’t think I can do this with stock :include. Does anyone have any
advice as to how I might be able to accomplish this?
