3. How to add date based filtering in Django admin?

You can add a date based filtering on any date field by setting the date_hierarchy.:

    date_hierarchy = 'added_on'

It looks like this:


This can be very costly with a large number of objects. As an alternative, you can subclass SimpleListFilter, and allow filtering only on years or the months.
