How to add after_filter-style render
Hello
I would like to execute specific action rendering something into page
after each of my ajax calls. In example I would like to update some
div or display an alert.
How I imagine it could work is as follows
class ApplicationController < ActionController::Base
after_filter :do_something_after_each_ajax_call
def do_something_after_each_ajax_call
if request.xml_http_request?
