New description:
This code uses ``_field`` instead of ``field``:
{{{
def __set__(self, instance, value):
if instance is None:
raise AttributeError("%s must be accessed via instance" %
self._field.name)
}}}
Example:
{{{
>>> from django.contrib.auth.models import Permission
>>> Permission.content_type.__set__(None, "foo")
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/Users/brad/work/foo/.env/lib/python2.7/site-
packages/django/db/models/fields/related.py", line 356, in __set__
raise AttributeError("%s must be accessed via instance" %
self._field.name)
AttributeError: 'ReverseSingleRelatedObjectDescriptor' object has no
attribute '_field'
}}}
