Per my verbose question, how can I modify this SQL statement to return an array of AR objects?
“SELECT id, user_id, activity_type_id, source_id, source_type,
COUNT(*) AS cnt
FROM activities
GROUP BY id, user_id, activity_type_id, source_id, source_type
HAVING COUNT(*) > 1”
I’m using Rails 2.3.
I saw you ask another question which looks related… are you trying to remove duplicate activities? Why not just prevent their creation in the first place with a unique index on the table and a validates uniqueness of on the activity model.
