Memoize invalidate BrowserView

Hi,
is there a way to invalidate a BrowserView?

I collect all my NewsItems in @@news and call in everywhere.

Now I want to recreate the view on ObjectModified (or IActionSucceededEvent)...

But a simple Event subscriber with
```global_cache.invalidate('package.path.to.view.NewsAggregated')````
does nothing

my Function


@ram.cache(lambda *args: time.time() // (60 * 3600))
def NewsAggregated(self, location):

    portal_catalog = api.portal.get_tool(name='portal_catalog')

    results = portal_catalog(
        path={
            'query': location
        },
        portal_type=['News Item'],
        review_state='published',
        sort_on='effective',
        sort_order='reverse'
    )

    .... other stuff
    return [Newsitems Dicts]

For sure popping out the annotations will work:

github.com

ploneintranet/ploneintranet/blob/f2d71704dab4d5f63b2f24cbeef7823c21bf5c78/src/ploneintranet/layout/tests/test_views.py#L535


    obj = api.content.create(
        title="Example page",
        container=self.folder,
        type="Document"
    )
    view = self.get_view('toggle-lock', obj)
    self.assertEqual(view.lock_info, None)
    self.assertNotEqual(view.lock_operations, None)
    view.lock()
    # Purge the cache
    view.request.__annotations__.pop('plone.memoize')
    self.assertEqual(view.lock_info['creator'], 'test_user_1_')
    view.unlock()
    # Purge the cache
    view.request.__annotations__.pop('plone.memoize')
    self.assertEqual(view.lock_info, None)


def test_on_screen_help(self):
    view = self.get_view('on-screen-help')
    # Test that we can create bubble links if the bubble is well known
    self.assertEqual(view.link_to(1), '')

I am not aware of a smarter method.
