Originally created by @jeremystretch on GitHub (Aug 10, 2024).

Originally assigned to: @jeremystretch on GitHub.

Deployment Type

NetBox Cloud

NetBox Version

v4.0.8

Python Version

3.10

Steps to Reproduce

  1. Create a device with five module bays
  2. Install a module into each bay
  3. View the device's module bays list

Expected Behavior

The installed modules should be prefetched automatically to optimize the number of database queries.

Observed Behavior

A separate query is issued for each installed module. This is because the base table's prefetch logic does not recognize reverse one-to-one relations.
