How do I get the current action from within a controller?

Question

How do I get the current action from within a controller? current_page? works for views, but not controllers.

redirect_to step3_users_path unless current_page?(step3_users_path)

I also tried

controller.action_name == 'step3'

I also tried

params[:action_name] == 'step3'

Answer 1

Controllers have action_name method/accessor (defined in AbstractController::Base for current rails, ActionController::Base for older)

Answer 2

you can use __method__ to get to the name of the current method.

e.g

 def Klass
   def method1
     puts __method__
   end
 end

 > k = Klass.new
 > k.method1
 => :method1

Once the request goes through Rails, you will be able to access this in the Controller:

params[:controller]
params[:action]

In a view, you can access action_name
