Rails: state_machine method for this or later states?

Question

Is there any way to access that functionality within the state_machine gem? Kinda like levels:

def check_if_editor
  redirect_to :root unless current_user.editor? OR ANY NEXT STATE
end

Can't find much in the docs. Thanks!

Answer 1

I don't think there is. I've come across the same requirement and solved it by creating a method that checks each acceptable state. I'm not entirely happy with it because if a new state gets introduced it potentially needs to be added to the list.

def after_state1?
  state2? || state3?
end

I saw a closed discussion on the state_machine gem (can't find it again now) where they said they didn't want to implement state ordering because it would make it too complicated.

Answer 2

You can use state machine methods state_paths (which returns an array of transitions from one specified state to another) and to_states (which converts the result to a nice array of states).

redirect_to :root unless editor_or_later?

def editor_or_later?
  states_after_editor = current_user.state_paths(:from => :editor, :to => :some_end_state).to_states
  states_editor_or_later = [:editor] +  states_after_editor

  states_editor_or_later.include? current_user.state.to_sym
end
