What problem does it solve ?

When using state_machine it's hard to run a callback on event after the transaction is committed.

after_commit_queue plugin addresses this problem.

Installation

Add this to your Gemfile and run bundle install

gem'after_commit_queue'

Include AfterCommitQueue module in your ActiveRecord model and you're ready to go. When registering a hook with run_after_commit you can supply either a method symbol or a block. No parameter is supplied when using the block form.
