define custom filesystem path for twig templates

Question

I\'ve already read How does Symfony2 detect where to load templates from? and another ton of articles on the web

The question was quite similar to mine, but the answ

Answer 1

To add a directory for twig templates I do this:

chdir(__DIR__);
$this->container->get('twig.loader')->addPath('../../../../web/templates/', $namespace = '__main__');

this allows me to put twig templates in a folder called 'templates' in the web folder and symfony 2.3 has no issues loading them.
