Hello all,
in a ViewSet, i prefetch a related model with filtered queryset based on
some query params:
filter_class = BarFilter
def get_queryset(self):
queryset = self.queryset
foo = self.request.query_params.get('foo', None)
if foo:
queryset = queryset.prefetch_related(Prefetch('resources',
queryset=Resource.objects.filter(foo=foo)))
else:
queryset = queryset.prefetch_related('resources')
return queryset
also, in filter class, i wan't to further filter the related models:
buz = django_filters.NumberFilter('resources__buz', lookup_type='gte',
distinct=True)
but, it seems that this filter ignores views get_queryset, as it applies
the related search on all related models even if the foo query param exists
