How to retrieve AccountId on insert of file.

system.debug('LinkedEntityId $$$$'+LinkedEntityId)

always gives OwnerId.

But after insert of file, I can retrieve two rows from below query on ContentDocumentLink - one row with AccountId(LinkedEntityId) and one row with OwnerID(LinkedEntityId)

SELECT LinkedEntityId, Id, ContentDocumentId FROM ContentDocumentLink where ContentDocumentId ='069r00000002COX'

trigger UpdateAccountWithFileLink on ContentDocumentLink (after insert) {
        list<Id> accIdList = new list<Id>();
        for (ContentDocumentLink cdl : trigger.new) {
            system.debug('LinkedEntityId $$$$'+LinkedEntityId);
            if(String.valueOf(cdl.LinkedEntityId).startswith('001')){
              accIdList =  cdl.LinkedEntityId; 
            }
        }
    }

  • if your event is INSERT of a file why don't you create a trigger on ContentDocument instead of ContentDocumentLink?

@Andrei.Z ParentId is available on ContentDocument if you enable CRM Content and assign to users.

    Welcome to SF.SE Peter. For ContentDocument, the ParentId is the ID of the library that owns the document. It's created automatically when inserting a ContentVersion via the API for the first time. I don't think that's the same ParentId that he's looking for. Its best to provide a reference for your answers when posting on SF.SE.

If you're needing the ContentDocumentLink record within the trigger context i.e. at the time of the record insertion rather than at any time afterwards, can't you just filter out the record where LinkedEntityId = :UserInfo.getUserId()?

SELECT ContentDocumentId,Id,IsDeleted,LinkedEntityId,ShareType,SystemModstamp,Visibility FROM ContentDocumentLink WHERE ContentDocumentId = '0698d000009mNclAAE' AND LinkedEntityId != :UserInfo.getUserId()
