Today I was trying to control what rendered on a page based on which controller action called it, and discovered the action_name method. It’s located in actionview:

pry> method(:action_name).source_location
=> ["/Users/jake/.rvm/gems/ruby-2.2.3/gems/actionview-4.2.4/lib/action_view/helpers/controller_helper.rb", 10]

Add this to your view code, and it you’ll get the relevant action:

pry> action_name
=> "index"

Same partial, different context:

pry> action_name
=> "drafts"

This method would allow conditionals like this (HAML):

- if action_name == 'index'
  Welcome to the index.
- else
  Welcome to the drafts.
