How to use extend filter query in blueprints

The CMS Questions
1

Hi,

i try to get all related pages to the page i am editing.

In PHP it would be something like this:

$page->children()->filter(function($child) use($page) {
    return $child->related()->toPages()->has($page);
});

But how can i use this in the blueprint yml?

This of course won’t work:

  exposes:
    label: Exposes
    type: pages
    query: kirby.page("exposes").children.filter(function($child) use($page) {return $child->building()->toPages()->has($page)})
    size: small

Thx in advance.

You need a custom method or page model
