Comment:
I'd like to reopen this ticket in favor of another use case scenario:
I have plenty of models that each have many DateTimeFields that are read
only, namely 'updated' and 'created' timestamps.
I want to customize how datetimes are displayed as HTML when they are
read_only, but unfortunately Django admin invokes the hardcoded display
functions to display read_only fields that don't have a widget set with
read_only=True. I don't want to customize it once for each of these
fields, I'd like to make a common abstract class that inherits from
ModelAdmin once for all my forms and have it change the generated HTML for
datetimefields for every subclass.
Using formfield_overrides with a widget with read_only=True isn't enough
because the AdminReadonlyField contents method wants the field to be
explicitly listed in the form fields before checking if read_only is True
on the widget.
I'd like to be able to provide a read only representation of field classes
from a ModelAdmin superclass.
