I want to provide a link in my app to download a new version to install.
I used link_to point to a method in a controller that calls System.app_install, but I want to leave the UI as is. Currently if I don't user render it shows 'undefined'.
Is there a way to call a method in a controller without rendering anything?
p.d.: I know I could do it with ajax but it won't work in blackberry then...
