v4.4.6

Python Version

3.12

Steps to Reproduce

Go to Extras → Custom Links (/extras/custom-links/).
In the filter form, pick an object/model type and click Apply.
Note that the results aren’t constrained as expected.
Inspect the URL/query string: the form submits object_type=<...>.
Repeat the same flow under Extras → Saved Filters (/extras/saved-filters/) with the object/model type filter and observe the same behavior.

Expected Behavior

Selecting an object/model type in the filter form should narrow the list to items tied to that ContentType. The filter should submit object_type_id=<content_type_id> so the underlying filterset receives the value it expects.

Observed Behavior

Observed Behavior
The filter form submits object_type=<...> rather than object_type_id=<...>, so the filterset ignores the value and the list doesn’t change (or returns incorrect/empty results).

Additional Context
While working on a related feature request, I noticed two FilterForms that define the wrong field name for ContentType filtering:

CustomLinkFilterForm
SavedFilterFilterForm

These should use object_type_id (or set field_name='object_type_id') instead of object_type to match the filterset convention elsewhere in NetBox.
