Updates FilterModifierMixin to only enhance form fields when the
associated model has a registered filterset. This provides plugin
safety by ensuring unregistered plugin filtersets fall back to
simple filters without lookup modifiers.
Test changes:
- Create TestModel and TestFilterSet using BaseFilterSet for
automatic lookup generation
- Import dcim.filtersets to ensure Device filterset registration
- Adjust tag field expectations to match actual Device filterset
(has exact/n but not empty lookups)
Changed filterset registration to use model identifiers ('{app_label}.{model_name}')
as registry keys instead of form classes, matching NetBox's pattern for search indexes.
Consolidated field enhancement logic in FilterModifierMixin by:
- Creating QueryField marker type (CharField subclass) for search fields
- Updating FilterForm and NetBoxModelFilterSetForm to use QueryField for 'q'
- Moving all skip logic into _get_lookup_choices() to return empty list for
fields that shouldn't be enhanced
- Removing separate _should_skip_field() method
- Removing unused field_name parameter from _get_lookup_choices()
- Replacing hardcoded field name check ('q') with type-based detection
Enable filter modifiers for single-choice ChoiceFields in addition to the
existing MultipleChoiceField support. ChoiceFields can now display modifier
dropdowns with "Is", "Is Not", "Is Empty", and "Is Not Empty" options when
the corresponding FilterSet defines those lookups.
The mixin correctly verifies lookup availability against the FilterSet, so
modifiers only appear when multiple lookup options are actually supported.
Currently most FilterSets only define 'exact' for single-choice fields, but
this change enables future FilterSet enhancements to expose additional
lookups for ChoiceFields.
Implements dynamic filter modifier UI that allows users to select lookup operators
(exact, contains, starts with, regex, negation, empty/not empty) directly in filter
forms without manual URL parameter editing.
Supports filters for all scalar types and strings, as well as some
related object filters. Explicitly does not support filters on fields
that use APIWidget. That has been broken out in to follow up work.
**Backend:**
- FilterModifierWidget: Wraps form widgets with lookup modifier dropdown
- FilterModifierMixin: Auto-enhances filterset fields with appropriate lookups
- Extended lookup support: Adds negation (n), regex, iregex, empty_true/false lookups
- Field-type-aware: CharField gets text lookups, IntegerField gets comparison operators, etc.
**Frontend:**
- TypeScript handler syncs modifier dropdown with URL parameters
- Dynamically updates form field names (serial → serial__ic) on modifier change
- Flexible-width modifier dropdowns with semantic CSS classes
