> how I can call the link_to() function from a class within my model?

You can also load template helpers from scripts outside the view, like inside actions, models or batch scripts.

Below, you see the loading of the Url helper, which you need to create links with link_to().

sfLoader::loadHelpers('Url');
$sUrl = link_to('myLink', 'module/action');
