Hi, I am trying to write a method or named_scope that will return me
things based on a grouping… AND I would like to see how many are in
that group.
I’ve got this:
named_scope :top, :group => “view_type, view_id”, :order =>
“count(view_id) desc”, :limit => 25
Which will (correctly) return me the things with the most rows in
descending order. But I would love to know how MANY rows there were in
each grouping. As if I were running this sql:
SELECT *, count(view_id) FROM trackers GROUP BY view_type, view_id
ORDER BY count(view_id) desc LIMIT 25
which will return me:
8 1 13 Genre 2008-08-12 18:54:42 2008-08-12 18:54:42 3 (<- this is
the
number of rows)
How can I best do this?
