In an symfony template you can get the base url of the application with:

url_for('@homepage', true);  

Using this code in an action causes:
Fatal error: Call to undefined function url_for() in ...
In an action this code should be used instead:

$baseUrl = $this->getController()->genUrl('@homepage', true);
