Using a puppet/facter fact in a Foreman smart class parameter?

Question

How can I use a puppet/facter fact like ${$::hostname} in a Foreman smart class parameter?

I've tried $hostname and $::hostname and just about every variant I can think of! I've even trawled through Google and Foreman docs and bug reports. Surely there's a simple answer?

It's an old question, but you use facts like you do in a ERB template, example:

<%= @host.shortname %>

would get you xyz of xyz.example.com
