Is after_commit actually running?

I am using rails 3.0.8 and am trying to use the after_commit callback.

It is defined here: https://github.com/rails/rails/blob/v3.0.8/activerecord/lib/active_record/transactions.rb#L210

It is referred to as one of the callbacks here: https://github.com/rails/rails/blob/v3.0.8/activerecord/lib/active_record/callbacks.rb#L22

Consider this:

class Car < ActiveRecord::Base after_commit do # this doesn't execute end after_commit :please_run def please_run # nor does this end end

Any ideas why this is not working? I assume that I am using it correctly.

If you are experimenting with this in your test suite, you need to set self.use_transactional_fixtures = false for this class. By default, Rails runs a test package inside a transaction and rolls back at the end to clear it. This makes your tests quick, but if you rely on transaction control yourself or this callback, it will not work.

Now you can use test_after_commit gem.
The readme says:

"Make after_commit test callbacks for Rails 3+ with transactional_names = true."
