If I try to assign list to `admin_order_field` to sort on multiple fields
(like `Model.Meta.ordering` does) like this:
{{{
@admin.register(Invoice)
class InvoiceAdmin(ModelAdmin):
def get_full_number(self, invoice):
return invoice.full_number
get_full_number.admin_order_field = ['issued__year', 'issued__month',
'-number']
}}}
I got following error:
{{{

eFlwzMqz/lib/python3.7/site-packages/django/contrib/admin/options.py",

elif order_field.startswith('-') and pfx == '-':
AttributeError: 'list' object has no attribute 'startswith'
}}}
This is similar to https://code.djangoproject.com/ticket/30981 which has
been fixed, but sorting on multiple fields is still hard to achieve.
