In this implementation, I added a title property as an example of how the Aggregate would receive and store data internally.

Go to project_management/issue.rb


  • Have each state be a subclass of Issue as a way of expressing that the instances are still an Issue, but they are a different variation/state.
  • Make it simple to pass data around between the different states.
  • Don't expose the internal data structure


  • Need to use a factory for initializing the aggregate root
  • The factory is also inherited by the subclasses. This makes it confusing when it return a New issue.
  • It's verbose to pass data property from one state to the next
