Hi

Do you know if there is a way to filter eagerly loaded models before
they are loaded from the database? Say I want to find a location by
its id, and in the same query load only subcategories where
subcategory.location_id = location.id. Right now I have this, but all
subcategories are getting loaded which is not what I want.

@location = Location.find(loc_id, :include => [:subcategories])

Thanks!
