David Lutterkort commented on DTACLOUD-499:
-------------------------------------------
To produce an array of references you would write
array :volume_templates, :ref => CIMI::Model::VolumeTemplate
though for MachineTemplate, things are a little messier, since the entry in the
volume_templates array is basically a VolumeTemplate with an additional
attribute (initialLocation). For that, you'd have to do (leaving out the
CIMI::Model prefix)
class VolumeTemplateWithLocation < VolumeTemplate
text :initial_location
end
class MachineTemplate < Base
array :volume_templates, :ref => VolumeTemplateWithLocation
end
At least, that's my reading of the spec .. somewhat ugly. Might want to ask the
working group to calrify.

> If you have this definition in CIMI model (MachineTemplate in this case):
> array :volume_templates do
> ref :volume_template
> end
> and you use this JSON in .from_json method to create an instance of the
> MachineTemplate:
> <snip>
> 'volume_templates' : [
> { 'volumeConfig' : { 'capacity' : '12345' } }
> ]
> </snip>
> The resulting
> 'machine_template.volume_templates.first.volume_config.capacity' will be
> 'nil'.
> I tried to play a bit with the input JSON and I found that if you use this:
> <snip>
> 'volume_templates' : [
> 'volume_template' : {
> { 'volumeConfig' : { 'capacity' : '12345' } }
> }
> ]
> </snip>
> The resulting
> 'machine_template.volume_templates.first.volume_template.capacity' is set
> properly to '12345' :-)
> The XML output then looks like:
> <snip>
> <volumeTemplate>
> <volumeTemplate>
> <volumeConfig>
> <capacity>10240</capacity>
> </volumeConfig>
> </volumeTemplate>
> </volumeTemplate>
> </snip>
> I think we need to do something smart in the 'array' to remove the upper
> 'volumeTemplate' or introduce something like 'ref_arr :volume_templates'.
> Anyway, I'm leaving this one to you David, as you might have better schema
> knowledge than me ;-)
