I need to display content of attachment within iframe that is embedded in the particular sObject.

When you upload file from notes&Attachments related list on salesforce classic its type is attachment and i have hard coded link for displaying content of this attachment

/servlet/servlet.FileDownload?file='[id of attachment]'

But when i upload this file from lightning its type is file.

so is it possible to display content of ContentVersion I guess or what its type is in iframe in the same way as attachemnt in my example? enter image description here enter image description here

You will need to query the contentLinkDocument records with the EntityId equal to the record Id .

And also ContentLinkDocument will give you Id of the content Document and you will need a query against content document to get the necessary file

SELECT ContentDocumentId FROM ContentDocumentLink WHERE LinkedEntityId = '[RECORD ID]'

Then SOQL on ContentDocument

Select Id ,Title from ContentDocument Where ID In :[CONTENTDOCUMENTLIST]


If you use Files or content related object there is a simple event with new lightning namespace which can be used

Here is a sample quick POC

<aura:component implements="force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,forceCommunity:availableForAllPageTypes" access="global" >
  <aura:attribute name="contentId" type="String" default="069B00000015QMwIAM"/>
 <lightning:button variant="brand" label="Preview Reciept" onclick="{!c.preview }" />

Note that the default here is the Id of the content document .

The controller code for same is below

  preview : function(component, event, helper) {
    recordIds: [component.get("v.contentId")]
  • in such a way i can only fetch ContentDocument object, but I need to render its content

  • rendering can be done via new event openfiles .You will fire that and a modal will render automatically . Commented Nov 4, 2016 at 15:07
  • unfortunately it does not resolve my problem, first I need to display content within iframe and also I can't open attachment in such a way only content document files, when I'm trying substitute id of attachemnt to default value of attribute '<aura:attribute name="contentId" type="String" default="00P58000005CoxPEAS"/> ' i'm getting error

  • In lightning experience the attachment is stored in the contentversion object .So this is the content document Id Commented Nov 6, 2016 at 20:43
  • no, if file's type is Attachment, we can't see it in Contentversion object
