Plone 6, Volto: find items containing a block

In my case I searched for items that contains any kind of “form” block:

Register a view (MyView):

configure.zcml

  <browser:page
      name="my-view"
      for="*"
      class=".admin.MyView"
      permission="cmf.ManagePortal"
      />

admin.py

from Products.Five.browser import BrowserView
from plone import api
from zope.component.hooks import getSite


def find_items_with_form_blocks():
    SEARCH_WORD = 'form'
    portal = getSite()
    catalog = api.portal.get_tool("portal_catalog")

    results = []

    def search_in_blocks(blocks):
        if not isinstance(blocks, dict):
            return False

        for block_id, block_data in blocks.items():
            if SEARCH_WORD in block_data.get("@type", ""):
                return True

            nested_blocks = block_data.get("blocks", {})
            if search_in_blocks(nested_blocks):
                return True

        return False

    for brain in catalog():
        obj = brain.getObject()
        if hasattr(obj, "blocks") and search_in_blocks(obj.blocks):
            results.append(
                {
                    "title": obj.Title(),
                    "url": obj.absolute_url(),
                }
            )

    return results


class MyView(BrowserView):
    def __call__(self):
        results = find_items_with_form_blocks()
        if results:
            for result in results:
                print(f"Title: {result['title']}")
                print(f"URL: {result['url']}")
                print("-" * 20)
        else:
            print("No results found.")

        import pdb

        pdb.set_trace()

        return results

Then go to localhost:8080/Plone/my-view

Title: Lorem Ipsum form
URL: http://localhost:8080/Plone/en/some/path
--------------------
Title: Lorem 2
URL: http://localhost:8080/Plone/en/another/path
--------------------
> /app/sources/my.addon/my/addon/browser/admin.py(54)__call__()
-> return results
(Pdb) results
[{'title': 'Lorem Ipsum form', 'url': 'http://localhost:8080/Plone/en/some/path'}, {'title': 'Lorem 2', 'url': 'http://localhost:8080/Plone/en/another/path'}]
