Get the environment name in a Twig template with Symfony2

Question

Is there a way to get the name of the current environment in a Twig template? I'd like to set some CSS style values depending on it.

Answer 1

http://symfony.com/doc/current/templating/app_variable.html:

<p>Application Environment: {{ app.environment }}</p> 

Answer 2

Use

app.environment 

e.g.

{% extends app.environment == 'dev' ? "::dev_layout.html.twig" : "::layout.html.twig" %}
