Question

```Def get_ordering(self, request, queryset, view):

"""
Ordering is set by a comma delimited ?ordering=... query parameter.

The ordering query parameter can be overridden by setting
the ordering_param value on the OrderingFilter or by
specifying an ORDERING_PARAM value in the API settings.
"""
params = request.query_params.get(self.ordering_param)
if params:
fields = [param.strip() for param in params.split(',')]
ordering = self.remove_invalid_fields(queryset, fields, view, request)
if ordering:
return ordering

# No ordering was included, or all the ordering fields were invalid
return self.get_default_ordering(view)

def filter_queryset(self, request, queryset, view):
ordering = self.get_ordering(request, queryset, view)

if ordering:
return queryset.order_by(*ordering)

return queryset
