"tl;dr: is there a way to make with_subelements work with dicts? Or something to that effect?"
Doesn't sound like you need the nested loop that subelements provides and you'd be happy with https://github.com/ansible/ansible/blob/devel/lib/ansible/runner/lookup_plugins/dict.py That is unless you want to loop over each locations for each user, in which case, sure, you're doing the right thing. If subelements can be made to do this unobtrusively patches would be accepted. On Tue, May 6, 2014 at 6:58 PM, David Reagan <[email protected]> wrote: > So, I took a look at creating a plugin.
