I got a lot of test failures using the original suggestion. First because newly created records weren't yet committed when the (test) worker ran, so I switched toafter_commit. Butafter_commit also fires on destroy, so it would fail trying to reindex destroyed records. Rails 6 introducesafter_save_commit for this purpose. Prior to Rails 6 it would beafter_commit ..., on: [:create, :update], but if you needed to change the next line toafter_commit ..., on: :destroy the latter callback would clobber the former, and this prevents that.
