helpers()

Provides a proxy to access helper methods from outside the view.

Note that the proxy is rendered under a different view context. This may cause incorrect behavior with capture methods. Consider using helper instead when using capture.

📝 Source code 
# File actionpack/lib/action_controller/metal/helpers.rb, line 94
      def helpers
        @helper_proxy ||= begin
          proxy = ActionView::Base.empty
          proxy.config = config.inheritable_copy
          proxy.extend(_helpers)
        end
      end
