@ -2804,16 +2804,16 @@ number of authors that have contributed blog entries:
.. code-block:: pycon
>>> from django.db.models import Count
>>> Blog.objects.aggregate(Count("entry"))
{'entry__count': 16}
>>> Blog.objects.aggregate(Count("entry__authors"))
{'entry__authors__count': 16}
By using a keyword argument to specify the aggregate function, you can
control the name of the aggregation value that is returned:
.. code-block:: pycon
>>> Blog.objects.aggregate(number_of_entries=Count("entry"))
{'number_of_entries': 16}
>>> Blog.objects.aggregate(number_of_authors=Count("entry__authors"))
{'number_of_authors': 16}
