N+1 issue on the /api/ipam/ip-addresses/ endpoint

[mulmat]

Deployment Type

Self-hosted

NetBox Version

v3.7.6

Python Version

3.10

Steps to Reproduce

Call the /api/ipam/ip-addresses/ endpoint with more than 1 assigned ip address in the database (important that the ip addresses are assigned and you are listing assigned ip addresses, for example by using assigned_to_interface=true filter)

Expected Behavior

No N+1 issue.

I can submit I PR if wanted (I think the issue is that IPAddressViewSet are missing assigned_object_type in the prefetch_related)

Observed Behavior

N+1 issue with the following query:

SELECT ••• FROM "django_content_type" WHERE "django_content_type"."id" = X LIMIT 21

Thank you for opening a bug report. I was unable to reproduce the reported behavior on NetBox v3.7.6. Please re-confirm the reported behavior on the current stable release and adjust your post above as necessary. Remember to provide detailed steps that someone else can follow using a clean installation of NetBox to reproduce the issue. Remember to include the steps taken to create any initial objects or other data.

@jeremystretch - forgot to mention that the ips must be assigned. I've updated the post now above + also verified that the issue also affects 3.7.6

As a reference, I created ips like this to reproduce the issue:

IPAddress.objects.create(
    address=ip,
    assigned_object_type=ContentType.objects.get(app_label="dcim", model="interface"),
    assigned_object_id=52,
)

@jeremystretch - I can fix a PR for this
