Using UPSERT PostgreSQL from Rails 4.2

Question

How do I use "UPSERT" or "INSERT INTO likes (user_id,person_id) VALUES (32,64) ON CONFLICT (user_id,person_id) DO NOTHING" in PostgreSQL 9.5 on Rails 4.2?

Answer 1

Have a look at active_record_upsert gem here: https://github.com/jesjos/active_record_upsert. This does the upsert, but obviously only on Postgres 9.5+.
