ministry_of_state

Because State machines are simple, they do not have to be greater than 2000 lines of code (and complexity).

Features

  • Supports rails4 now. No changes required.

  • Events are wrapped in a transaction and record is locked before going for a state change.

  • Ignores dirty attributes while going for state change. This means unlike AASM you can't use an event transition as shorthand of `save`.

  • Events and states can be inherited across classes.

  • Simple 136 lines of code, covered with close to > 98% test coverage.

Using it

class User < ActiveRecord::Base
  include MinistryOfState
  ministry_of_state('status') do
    add_initial_state 'pending'
    add_state :active
    add_state :pending_payment

    add_event(:activate) do
      transitions(:from => :pending, :to => :active)
    end
  end
end

Installation

Add this line to your application's Gemfile:

gem 'ministry_of_state'

And then execute:

$ bundle

Or install it yourself as:

$ gem ministry_of_state

Contributing to ministry_of_state

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet

  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it

  • Fork the project

  • Start a feature/bugfix branch

  • Commit and push until you are happy with your contribution

  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.

  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
