ActiveRecord::Base.foreach

[djberg96]

Little did I know that ActiveRecord doesn't have a truly iterative way for dealing with results. You get the find method, with its various incantations of :all, :first, :limit, etc, but there's not way to iterate over every record in turn without slurping the result set into memory first

I believe since rails 2.3.2 it provides find_in_batches and find_each. Check active_record/relation/batches.rb

find_in_batches is the backend to find_each I think. But, as I mentioned, it still slurps 1000 records at a time, and it's broken in conjunction with the composite_primary_keys library.
