-----------------------------------------+------------------------
The new view permission is extremely useful, and encourages more use of
the Django Admin tool. It has highlighted a limitation in the rendering of
`readonly_fields` that can be easily addressed. At the moment,
`readonly_fields` (or all fields when the user has only `can_view`) can
only have custom rendering or formatting if they are custom properties or
new fields (created in the ModelAdmin), existing fields can't be changed.
In my use-case I have a number of rich text enhanced `TextField`s, which
when rendered as read-only show up as HTML and can't be marked safe. In
this case creating a custom field in the `ModelAdmin` where the Field can
be output with `mark_safe()` doesn't work as the original field needs to
exist for users with change permissions, the only other way is to include
the field twice which creates UX issues.
If, in ModelAdmin, you could override the formatting/output of a read-only
field it would address this issue. Alternatively, as mentioned in the
comments of #14802, the idea of Fields having a method that is called by
admin to handle the read-only HTML rendering would also do the trick as is
related.
