If you are using acts_as_ferret, it will never get called. The acts_as_ferret declaration would go on the root class. Updates to the child classes would not trigger an aaf index update in the root class.
If you want to real-time index updates, you would have to add an after_save callback to the child class that forces an aaf update in the root class. If real-time updates are not too important, then you could dump the child updates into a queue that performs bulk updates. This would minimize the number of times this method gets called. If you're worried about 200+ SQL calls, don't perform the join in ruby, do it via SQL using CONCAT and "Advanced Attribute" as described in AWDWR, 19.3. -Chris On Tue, Nov 20, 2007 at 02:01:39PM +0100, Till Vollmer wrote: > Hi, > Thank you for the clue. > Ok, like a virtual attribute.
