-------------------------------------+-------------------------------------
Fields using `RelatedFieldWidgetWrapper` have three links/buttons next to
them to go to the Change/Add/View views for their model. Those links use a
bit of JS to toggle whether the link is active or not based on whether the
field has a value.
This link state (disabled/enabled) isn’t communicated to screen reader
users in any way. We should be able to solve this by adding a `aria-
disabled="true"` attribute on those links when they are disabled (making
sure to remove the attribute when the links are enabled).
- Template:
https://github.com/django/django/blob/main/django/contrib/admin/templates/admin/widgets/related_widget_wrapper.html
- And I believe the "link enabled/disabled" logic happens here:
https://github.com/django/django/blob/main/django/contrib/admin/static/admin/js/admin/RelatedObjectLookups.js
_In addition_ this is unrelated but it’d be much nicer for screen reader
users if the images within those links had `alt=""`. Right now the
presence of `alt` means screen reader users will hear "link, image,
Change" – the fact there’s an image is completely irrelevant here. It’d be
much better to instead have `link, Change selected <thing>` (coming from
the title attribute).
