attr

Usage example::

# Django proposes:
def my_calculated_field(...
my_calculated_field.short_description = 'Field'
my_calculated_field.admin_order_field = 'real_field'

# DRY:
@attr(short_description='Field', admin_order_field='real_field')
def my_calculated_field(...

Get it::

sudo pip install attr
from attr import attr

New popular attrs.org <http://attrs.org>_ used by pytest.org <https://pytest.org>_ defines another "attr" package that shadows this "attr" module.

Please use "dry_attr" alias to unshadow it::

from dry_attr import attr
from dry_attr import dry_attr
