Datamapper : One To Many

[eluser]Flyingbeaver[/eluser]
Hi

I need help on this plz :


2 tables

Service : has many Sub_Service
Sub_Service : has one Service

My code :

Code:

$services = new Service();
        $services->where('org_id', $org_id)->get();
        $services->sub_service->get();

        foreach($services as $service)
        {
            echo $service->title;

            foreach($service->sub_service as $sub_service)
            {
                      echo $sub_service->title;
            }
        }

But it doesn't work, if I want to access sub_service i have to take it out of the first loop and do somthing like

Code:

foreach($services->sub_service as $sub_service)
            {
                   echo $sub_service->title;
            }

But this is not what I want, i want to get an array like this one :


Service 1
--Subservice 1
--Subservice 3
Service 2
Service 3
--Subservice 2


Info i'm using DM 1.8 and CI2.

Thx for ur help
