I have added a before_filter into the SitesController for user authentication, but whenever i use a redirect_to or render in my before_filter action i get famous ActionController::DoubleRenderError . I know the reasons but i don't how i could do a redirect_to anyway, so that if a user is not authenticated, he got redirected to the root page. Is this anyway the correct way of authentication in radiant, thus setting a before filter in SitesController? Or is there a better way?
