I'm a bit surprised to hear that doesn't work when the hash passed to
create_resources() is initialized via a literal, as you show. If that's
how you plan to do it, though, then you could instead establish the
relationship separately by use of the chain operator:
Class['myclass'] -> Application::Install['test']
That's not really what I'd call "dynamic", however, so I suspect what
you're really trying to do is express that hash in hiera data. Indeed that
*won't* work, at least not with the default back-end (YAML), because YAML
has no mechanism for expressing Puppet resource references. The value
"Class[myclass]" is just a string in YAML. You could work around such a
problem by expressing required class names in your data rather than class
references (and then applying the chain operator appropriately in your
defined type).
