Assign IPAddress to a Virtual interface issue

[evsoares-meli]

Hello guys, I'm having trouble assigning an IP to a virtual interface via custom script and/or nbshell, the code returns this error: TypeError: Direct assignment to the reverse side of a related set is prohibited. Use interface.set() instead.

This is the code: (netbox v2.10.8)

iface = Interface.objects.get (device = fw, name = 'dmz')

fw_mgmt_ip = IPAddress (
    address = '10.0.20.10/28',
    interface = iface
)

fw_mgmt_ip.save ()

fw.primary_ip4 = fw_mgmt_ip
fw.save()
return fw

Sorry for my bad understand of django.
Thanks in advance

As of Netbox v2.9.0, Interface was split into Interface and VMInterface.

Hence there is no longer an interface attribute on IPAddress, there is assigned_object. This is because an IPAddress can be linked to either an Interface or a VMInterface, and it uses a generic relation for this.

Here is some working code:
https://github.com/netbox-community/reports/blob/master/scripts/create_vm.py#L88

It creates a VirtualMachine, a VMInterface and an IPAddress, and links them together.
