    Aggregation functions will return ``None`` when used with an empty

    ``QuerySet``. For example, the ``Count`` aggregation function will return

    ``None`` instead of ``0`` if the ``QuerySet`` contains no entries.

    Aggregation functions return ``None`` when used with an empty

    ``QuerySet``. For example, the ``Sum`` aggregation function returns ``None``

    instead of ``0`` if the ``QuerySet`` contains no entries. An exception is

    ``Count``, which does return ``0`` if the ``QuerySet`` is empty.
