Actually I'd call it magic or voodoo, but not a dirty secret. It's actually a brilliant/necessary part of the arel features in Rails 3. When you select a recordset using Rails 3 arel features (where, order, etc), it doesn't actually call the DB until you iterate over the resultset. This means if that part of the view is cached, it won't actually hit your DB at all. If files was an array it would have had to call the DB to fill the array, only for it not to be used. So, the OP's code snippet is not surprising - @product.files is not an array, but if you use the eql? method on that object it will compare it's internal data to an empty array (but arrays know nothing about this ActiveRecord class).
