Django Admin date_hierarchy with zero queries
----------------------------------------------

The built-in `date_hierarchy`_ tag performs a query to find the dates for which there is data.
On large tables this query can be very expensive.

To prevent additional queries, set ``date_hierarchy_drilldown = False`` on the ``ModelAdmin``.
When drill-down is disabled the tag will generate a default range of dates based solely
on the selected hierarchy level - without performing a query.

Default options for hierarchy levels:

- None - +-3 years from current year.
- Year - all months of the selected year.
- Month - all days of the selected month.

When ``date_hierarchy_drilldown = True`` or when not set the default behaviour is preserved.

.. _`date_hierarchy`: https://docs.djangoproject.com/en/1.11/ref/contrib/admin/#django.contrib.admin.ModelAdmin.date_hierarchy
