Solve the following python programming problem given the following code:
def create_sorted_many_related_manager(superclass, rel, * args, **kwargs) : 
    RelatedManager = create_forward_many_to_many_manager (superclass, rel, * args, ** args) 
    class SortedRelatedManager (RelatedManager) : 
        def get_queryset(self) : 
            try : 
                return self.instance._prefetched_objects_cache [self.prefetch_cache_name] 
except (AttributeError, KeyError) : 
                if (not hasattr (RelatedManager, 'get_queryset')) : 
                    queryset = super (SortedRelatedManager, self).get_query_set () 
else : 
                    queryset = super (SortedRelatedManager, self).get_queryset () 
return queryset.extra (order_by = [('%s.%s' % (rel.through._meta.db_table, rel.through._sort_field_name))]) 
get_query_set = get_queryset 
        if (not hasattr (RelatedManager, '_get_fk_val')) : 
            @ property 
            def _fk_val(self) : 
                if (not hasattr (self, 'related_val')) : 
                    return self._pk_val 
return self.related_val [0] 
def get_prefetch_queryset(self, instances, queryset = None) : 
            if (django.VERSION < (1, 6)) : 
                result = super (SortedRelatedManager, self).get_prefetch_query_set (instances) 
else : 
                if (django.VERSION < (1, 7)) : 
                    result = super (SortedRelatedManager, self).get_prefetch_queryset (instances) 
else : 
                    result = super (SortedRelatedManager, self).get_prefetch_queryset (instances, queryset) 
queryset = result [0] 
            queryset.query.extra_order_by = [('%s.%s' % (rel.through._meta.db_table, rel.through._sort_field_name))] 
            return ((queryset,) + result [1 :]) 
get_prefetch_query_set = get_prefetch_queryset 
        def set(self, objs, **kwargs) : 
            kwargs ['clear'] = True 
            super (SortedRelatedManager, self).set (objs, ** kwargs) 
set.alters_data = True 
        def _add_items(self, source_field_name, target_field_name, * objs) : 
            from django.db.models import Max,...

    
    

    Fix the buggy line: RelatedManager = create_forward_many_to_many_manager (superclass, rel, * args, ** args)
