Hi,
I'm trying to adapt a preseed provisioning template so it can deal with
bond interfaces.
While looking at the erb templates I encounter expressions like "dhcp =
subnet.dhcp_boot_mode" or "if !interface.managed?", I was wondering, where
can I find a complete description of these "objects" and their "properties
and methods?".
Thank you.
Xavier
Hi Xavier,
You can find an (outdated) list of these expressions here:
http://projects.theforeman.org/projects/foreman/wiki/TemplateWriting#Functions-and-macros
Keep in mind you can disable safe mode rendering in Settings if you
want to use other variables. They mostly have to do with the way
Foreman represents objects internally, look in the Foreman source for
objects in app/models that contain 'class Jail << ::Safemode::Jail' to
see exactly the attributes allowed per class.
Templates are written in ERB, and these parts are just Ruby code, so
you can experiment using the Rails console. 'foreman-rake console' or
cd-ing to the Foreman directory then running 'rails c' should bring it
up. Then you can look for objects like 'host =
Host.find_by_name('xavier.naveira.com')' and start fiddling with
that.
Let us know if you need more help. Thank you!
