New decorators for the admin site
---------------------------------
The new :func:`~django.contrib.admin.display` decorator allows for easily
adding options to custom display functions that can be used with
:attr:`~django.contrib.admin.ModelAdmin.list_display` or
:attr:`~django.contrib.admin.ModelAdmin.readonly_fields`.
Likewise, the new :func:`~django.contrib.admin.action` decorator allows for
easily adding options to action functions that can be used with
:attr:`~django.contrib.admin.ModelAdmin.actions`.
Using the ``@display`` decorator has the advantage that it is now
possible to use the ``@property`` decorator when needing to specify attributes
on the custom method. Prior to this it was necessary to use the ``property()``
function instead after assigning the required attributes to the method.
Using decorators has the advantage that these options are more discoverable as
they can be suggested by completion utilities in code editors. They are merely
a convenience and still set the same attributes on the functions under the
hood.
