Best approach to counter_cache and summarization

[narath]

Closure tree looks great. I need to be able to report out on count (count the number of all descendents) and do some other summarization (summing points for the node and all children). Is there a recommended approach for this? Would counter_cache work appropriately for the node object? For the more complicated summarization (summing points and totals for all descendents) are their custom callbacks that can be used?

I have the same question. At least an option for counter_cache on parent relation would be nice. awesome_nested_set has such a thing and it's quite useful because we filter out some entries with no children (empty placeholder threads in comments).

//EDIT:

reflections["parent"].options[:counter_cache] = :children_count
