NetBox Version

main (v4.2.7)

Python Version

3.10

Steps to Reproduce

1. Create a Site named Site1
2. Create a Prefix 10.0.0.0/16 with:
   • Scope Type: Site
   • Scope: Site1
3. Navigate to IPAM → Prefixes (PrefixListView)
4. Select the prefix 10.0.0.0/16 using the checkbox (✅)
5. Click Edit Selected to initiate a bulk edit
6. In the bulk edit form:
   • Change the Scope Type dropdown to Location (or any other valid choice)
   • Attempt to select a Scope from the corresponding dropdown

Expected Behavior

• After selecting a Scope Type, the Scope dropdown should become active and list the available objects of the selected type.

Observed Behavior

• The Scope Type field gets reset to None
• The Scope field remains disabled
• This effectively prevents setting a Scope during bulk edits

---

When performing bulk edits on models utilizing a ContentTypeChoiceField (typically for GenericForeignKey fields), the dynamic behavior of the Scope field is broken. Specifically, selecting a Scope Type fails to properly enable and populate the corresponding Scope field.

This is a recent regression, which is included in the upcoming v4.2.7 patch release.
