StateMachines::AfterTransitionCommit

Add #after_transition_commit to your active record state machines. This ensures that queueing up async jobs happens after the transaction is committed to the database.

Add this line to your application's Gemfile:

gem 'state_machines-after_transition_commit'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install state_machines-after_transition_commit

Call add_after_transition_commit_callback inside your state machine to add the after transition commit callbacks.

Anywhere you use after_transition you can replace with after_transition_commit:

state_machine :state, initial: :created do
  add_after_transition_commit_callback

  state :created
  state :complete

  event(:finish) do
    transition :created => :complete
  end

  after_transition_commit :created => :complete do |record|
    YourAsyncJob.perform_later(record)
  end
end

Don't trigger saves in your after_transition_commit block or you'll end up in an infinite loop. The typical use case is for queueing async jobs.

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
