Hi all,
is there a way for qualifying variables inside a template?
I've tried :
Name = <%= "${::hostname}" %>
but the var gets "${::hostname}" value.
thinking in version 2.8, is it needed?
http://docs.puppetlabs.com/guides/scope_and_puppet.html says nothing
about this...
TIA,
Arnau

Use something like <%= scope.lookupvar('hostname') %>

There's also more documentation on using puppet specific methods in templates at http://docs.puppetlabs.com/guides/templating.html

Ok.
so template and class share the scope and tehre's no need to qualify its vars.
Thanks for your replies and for the link.
Cheers,
Arnau

what is the incantation that would work for iteration?
scope.lookupvar('::varname').each
Produces puppet error: undefined method `each' for :undefined:Symbol

this looks all right but
> Produces puppet error: undefined method `each' for :undefined:Symbol
it seems that the lookup itself fails. Are you certain you've got the
right name, and that the variable is defined in your context?
It may also be more readable to do
myvar = scope.lookupvar('::varname')
myvar.each do ...
HTH,
