symfony - Getting current route twig -

i want current route on twig , used 2 code fail

code 1:

 {% if app.request.get('_route') == 'my_route' %}       //do  {% endif %} 

code 2:

{% if app.request.attributes.get == 'my_route' %}       //do  {% endif %} 

use "app_dev.php" @ end of url debug , check route being used @ bottom. example show "route1" here:

then in twig template can use this:

{% if app.request.attributes.get('_route') == 'route1' %}     <h1>test</h1> {% endif %} 

i verified works. i'm using symfony3 though.

maybe try instead of "app.request.attributes.get()", try these:

• app.request.pathinfo
• app.request.uri

see if work.

also if route indeed null, try:

{% if app.request.attributes.get('_route') == '' %}     <h1>test</h1> {% endif %}
