Puppet users - Jan 2013 - Using resource collectors with variables from the collected resource?

Hi everyone.  An example is worth 1000 words, so here''s one:

In this example I would like the home directory to be overridden to 
/testdir/me:

@user { ''me'':
  ensure => present,
  home => ''/home/$title'',
  tag => ''userclass1''
}

User <| tag == ''userclass1'' |> {
  home => "/testhome/$title"
}

It actually gets overriden to /testhome/main, ''main'' being the
class the
collector is in, puppet apply tries to:
''/usr/sbin/useradd -d /testhome/main me''

I can sort of solve this problem by:

@fancyuser { ''me2'':
  tag => ''userclass1'',
}

define fancyuser($homedir_prefix=''/home'') {
  user { ''$title'':
    home => "$homedir_prefix/$title", }
}
Fancyuser <| tag == ''userclass1'' |> {
  homedir_prefix => "/testhome"
}

This works as expected, as it doesn''t rely on the
''$title'' of the collected
virtual resource.  I''d rather just use the virtual resource''s
$title.  Is
this possible, or am I asking too much from the resource collector?

Thanks!
Richard

I would try using $name instead of $title in those.

No, I tried that as well.  Still reports the class of the collector and not 
the $name of the virtual resource.

Damn.
Sorry dude I am not sure what else else to suggest.
Your wrapper define may be the best way to go.
Unless you can configure the user adding functions to use different home
prefixes for a user based on group or something like that.
The only other idea I can think of is setting up a symlink from the
/home/$user directory to the other dir before you create the user.

It is not possible.  Variable references are resolved in the scope in which 
they appear, which in this case is the one provided by the class or defined 
type instance in which the collection is declared.  The collection does not 
establish a new scope.
