Hello everyone, I got a problem ``` referenced_fields = set(chain.from_iterable( (rf.attname for rf in rel.field.foreign_related_fields) for rel in get_candidate_relations_to_delete(related_model._meta) )) sub_objs = sub_objs.only(*tuple(referenced_fields)) ``` It will never work, when delete a foreign key, it will select all fields. it should not be like below code? ``` referenced_fields = set(rel.attname for rel in [f for f in related_model._meta.get_fields(include_hidden=True) if f.many_to_one]) sub_objs = sub_objs.only(*tuple(referenced_fields)) ```
