Hello Peter, I believe you need to use <%= foreman_server_fqdn %> without '@' to get the url. We don't make all settings accessible in templates, this one has it's own macro defined and can be called as mentioned above. Could you please let us know where did you find that you could use @foreman_server_fqdn and whether the macro (without @) works for you? It works on my Satellite 6.2 instance. Thank you.

Comment 3 Peter Vreman 2016-10-27 14:54:39 UTC

Without the @ the <%= foreman_server_fqdn %> works.
Strange that there is no error for an undefined variable.

Comment 4 Marek Hulan 2016-10-31 09:13:48 UTC

The reason is that it's valid Ruby code, instance variables (starting with @) defaults to nil. Thanks for confirmation.
