Hi,

I recently upgraded from Netbox 2.8.8 to 2.11.4, and have been having some issues with export templates. Due to the adjustments with circuit terminations, I have been trying to get the template adjusted to the new cable_peer model but I am not sure what I am doing wrong.

To test, I cut it down to a really simple export template is from DCIM -> Device:

{%- for device in queryset -%}
## {{ device.name }} ({{ device.device_type.model }})
{%- for interface in device.interfaces.all() %} {#- Begin Interfaces Loop #}

{{ interface.name }},{{ interface.mode.value }},{{ interface.cable.peer.circuit.cid }}

{%- endfor %} {#- End Interfaces Loop #}
{%- endfor %} {#- End of main loop #}

I keep getting errors like the following:

There was an error rendering the selected export template (Interface Listing Test): 'dcim.models.device_components.Interface object' has no attribute 'cable_peer'

It seems I can't access data outside of the interface scope any longer.

Previously, this would have been {{ interface.connected_endpoint.circuit.cid }} and has been working ok for me until this point.

Can anyone point me in the right direction with this?

Thanks!

The way to explore the data model interactively is with nbshell.

>>> d = Device.objects.get(name="ont1")
>>> d
<Device: ont1>
>>> i = d.interfaces.get(name="WAN")
>>> i
<Interface: WAN>
>>> dir(i)
... shows lots of attributes ...
>>> [n for n in dir(i) if "peer" in n]
['_cable_peer', '_cable_peer_id', '_cable_peer_type', '_cable_peer_type_id', 'get_cable_peer']
>>> i.get_cable_peer
<bound method CableTermination.get_cable_peer of <Interface: WAN>>
>>> i.get_cable_peer()
<CircuitTermination: Termination A: XYZ Site>
>>> i.get_cable_peer().circuit
<Circuit: 20115>
>>> i.get_cable_peer().circuit.cid
'20115'

Many thanks for the pointers Brian. Up to now I have been using the API web views, but I will use nbshell from now on.

I just did a quick modification and test on the export template, and this provides me with the circuit IDs once again:

{%- for device in queryset -%}
## {{ device.name }} ({{ device.device_type.model }})
{%- for interface in device.interfaces.all() %} {#- Begin Interfaces Loop #}

{% if interface.get_cable_peer().circuit %}
{{ interface.get_cable_peer().circuit.cid }}
{% endif %}

{%- endfor %} {#- End Interfaces Loop #}
{%- endfor %} {#- End of main loop #}

Output:

## abc-sw1 (EX2200-C-12P-2G)
