Rails flash.now within after_action

Code on this one speaks for itself.

This works...

class SomeController < ApplicationController

  def index
    flash.now[:alert] = 'Something got borked!'
  end

end

And this doesn't (flash is empty)...

class SomeController < ApplicationController

  after_action :test_flash

  def index
  end

  def test_flash
    flash.now[:alert] = 'Something got borked!'
  end

end

Using Rails 4.0.2, Ruby 2.1.0

Thoughts anyone?

At the end of your index action rails just renders the new page as you have not specified anything different. after_action is executed after rendering the index page i.e., it adds a callback which would be called after the execution of index action is completed. So, test_flash has no effect as its too late and index page is already rendered.

EDIT:

If you want to call test_flash before rendering then you can override render method and do something like : 

  def render *args
    test_flash
    super
  end
