Rails 3: How to identify after_commit action in observers? (create/update/destroy)

Question

I have an observer and I register an after_commit callback. How can I tell whether it was fired after create or update? I can tell an item was destroyed by asking

Answer 1

Based on leenasn idea, I created some modules that makes it possible to use after_commit_on_updateand after_commit_on_create callbacks: https://gist.github.com/2392664

Usage:

class User < ActiveRecord::Base
  include AfterCommitCallbacks
  after_commit_on_create :foo

  def foo
    puts "foo"
  end
end

class UserObserver < ActiveRecord::Observer
  def after_commit_on_create(user)
    puts "foo"
  end
end
