Symfony2, check if an action is called by ajax or not

Question

I need, for each action in my controller, check if these actions are called by an ajax request or not.

If yes, nothing append, if no, i need to redirect to the home

Answer 1

For a reusable technique, I use the following from the base template

{# app/Resources/views/layout.html.twig #}
{% extends app.request.xmlHttpRequest 
     ? '::ajax-layout.html.twig'
     : '::full-layout.html.twig' %}

So all your templates extending layout.html.twig can automatically be stripped of all your standard markup when originated from Ajax.
