Named scopes for states in state_machine

I use state_machine with ActiveRecord on one of my Rails 3.1 application. I found the syntax to access records with different states to be cumbersome. Is it possible to define each state to be the scope at the same time without writing scope definitions by hand?

Consider following example:

class User < ActiveRecord:Base
  state_machine :status, :initial => :foo do
    state :foo
    state :bar

    # ...
  end
end

# state_machine syntax:
User.with_status :foo
User.with_status :bar

# desired syntax:
User.foo
User.bar
Solution

  • I also needed this functionality, but state_machine has nothing similar. Although I've found this gist, but aasm seems like a better state machine alternative in this case.
