One of the things I am planning for the next version of DMZ is to remove the has_one restriction on include_related. The original reason for this restraint had to do with how objects were stored in the all array, but for a while now, DMZ would work fine with multiple results per id.
Of course, it won't do exactly what might be expected (unless I write a lot more logic in), since you'll get one row per unique result, even if that means multiple rows per id.
(I might add some logic in to optionally loop through the results and consolidate the rows when instantiating related items.)
But don't wait around on the next version... It might be until Fall before I can get to working on DMZ again.
