Vulnerability in EPiServer.Forms
I need to get all the pages that use a block or media item when that block or media item is published. I can hook into the publish event ok and I can get pages using
var repository = ServiceLocator.Current.GetInstance<IContentRepository>();var references = repository.GetReferencesToContent(e.ContentLink, true).ToList();
However if a block is nested within a block the above will only get the parent block and not the page where the parent block is used. Similarly if a block was nested several times then it would only get the immediate parent.
Has anyone done anything similar in the past to get the ultimate page using the block?
I think you’re stuck with recursive GetReferencesToContent if reference is a block.
I’m curious about the case here. Are you updating changed date on the page when a block or media file is changed?
Yes, that seems to be the issue, I get parent from child but when I get the references for the parent it gives me the child.
Not exactly but that would be a useful case. What we need to do is remove a page from a custom cache when anything used by the page is updated, block or media.
Any suggestions? I looked into getting parent items but for blocks this is the folder where the block 'lives' rather than the page.
I do something similar in my "BlockSearch" package. You can use something like this maybe?
List<ContentReference> referencingContentLinks = this.ContentSoftLinkRepository.Load(contentLink: contentLink, reversed: true)
link.SoftLinkType == ReferenceType.PageLinkReference
&& !ContentReference.IsNullOrEmpty(contentLink: link.OwnerContentLink))
.Select(link => link.OwnerContentLink)
