symfony2: how to access service from template

Solution 1:

You can set the service a twig global variable in config.yml, e.g

#app/config/config.yml
twig:
    globals:
        your_service: "@your_service"

And in your template.html.twig file you can invoke your service this way:

{{ your_service.someMethod(twig_variable) }}
