When deleting stale ContentTypes during remove_stale_contenttypes, the
pre_delete signal triggers notify_object_changed(), which calls
has_feature() with the ContentType instance. For stale types (those with
no corresponding model class), model_class() returns None, which then gets
passed to issubclass() in the feature test lambda, causing a TypeError.
The previous implementation in has_feature() checked for None before
attempting ObjectType lookup. The optimization in 5ceb6a6 removed this
safety check when refactoring the ContentType code path to use direct
feature registry lookups. This restores the null check to maintain the
original behavior of returning False for stale ContentTypes.
Introduce `ContentTypeFilter` across several filtersets, including
`object_type`, `related_object_type`, `assigned_object_type`, and
`parent_object_type`. This improvement enhances filtering specificity
and aligns with existing usability standards.
Closes#20554
Introduce `ranges_to_string_list` for converting numeric ranges into a
list of readable strings. Update the `vid_ranges_list` property and
templates to use this method for better readability and maintainability.
Add related tests to ensure functionality.
Closes#20516
Commit d22246688 added form prefix support to the `GET` handler to fix
Markdown preview functionality in quick add modals. The form prefix
allows Django to properly namespace field names and IDs when rendering
forms within the quick add modal context.
However, the corresponding change was not made to the `POST` handler. This
created a mismatch where form fields were rendered with the `quickadd-`
prefix during `GET` requests, but the `POST` handler instantiated forms
without the prefix. When users submitted quick add forms, Django looked
for unprefixed field names like `address` and `status` in the `POST` data,
but the actual submitted data used prefixed names like `quickadd-address`
and `quickadd-status`. This caused validation to fail immediately with
"This field is required" errors for all required fields, making every
quick add form unusable.
The fix adds the same prefix detection logic to the `POST` handler that was
added to the `GET` handler, checking for the `_quickadd` parameter in the
query string and applying the `quickadd` prefix when present. This ensures
consistent form field naming between rendering and validation.
A regression test has been added to `MACAddressTestCase` to verify that MAC
addresses can be successfully created via the quick add modal, preventing
this issue from recurring. This test should be promoted to a template
test whenever it becomes possible to determine if a model should support
quick-add functionality.
Introduce a generic lookup for ArrayField(RangeField) that matches rows
where a scalar value is contained by any range in the array
(e.g. VLANGroup.vid_ranges).
Replace the raw-SQL helper in the VLANGroup FilterSet (`contains_vid`)
with the ORM lookup for better maintainability.
Add tests for the lookup and the FilterSet behavior.
Closes#20497
Adjusts the schema mapping for `IntegerRangeSerializer` by setting
`match_subclasses` to `True` and refining the array definition. Adds
an example field for clarity in generated OpenAPI documentation.
