Countercache for children

Need Help
1

I am looking at the countercache, and was wondering if there is easy way to use it with parents and children?

https://book.cakephp.org/3.0/en/orm/behaviors/counter-cache.html#advanced-usage

The CounterCache behavior works for belongsTo associations only.

you can probably (because i havent tried) set it with parents as Children belongsTo Parent

`$this->addBehavior(‘CounterCache’, [
‘ParentCategories’ => [
‘article_count’ => function ($event, $entity, $table, $original) {

                $categories = $this->find('all')->where(['parent_id' => $entity->parent_id]);
                $collection = new Collection($categories);
                
                return $collection->sumOf('article_count');
            },
        ]
    ]);`

I have this. But is not working.

Actually what I want is when the article gets added/updated that the counts run. But this does not happen?

5

Also when you update one category it will update the direct parent. But it will not recursively update the parent of the parent.

6

I guess the countercache does not trigger countercache on deeper relations. It only works on a 1 to 1 basis?

Anyone have any idea how to do it?
