RestPy:Class based queries

[muthvar1]

Hi Folks,
I remember in one of the deep dive sessions provided to us we went through an example that describes my query below. But I can't seem to recollect the solution. Would someone be able to provide the answer or point to an implementation.

What I basically need is a class based query for a specific class that is the input to the function, without having to derive the tree of parent Objects.

What works now:

ipV4Object = ethernetObject.Ipv4.find(Name='1/11/13_ethernet_t0:ctx0_b5_sepg4_ 1')

What I need to work: IxNetwork.Topology.DeviceGroup.Ethernet.Ipv4.find(Name='1/7/11_ethernet_t0:ctx1_b4_sepg5_ 1')

Right now the above command typed as is results in the following error.

IxNetwork.Topology.DeviceGroup.Ethernet.Ipv4.find(Name='1/7/11_ethernet_t0:ctx1_b4_sepg5_ 1')
Traceback (most recent call last):

end = len(self._parent.href)

We currently do not support this methodology for finding instances as parent instances are required at this time.
We are looking at implementing a solution that does not require parent instances.
