Vlocity Facts #26 || Can we display files with out using LWC and file related list?

 Yes we can display the files with out using LWC but we need to write triggers and we can display with the help off Flexcard.

When we upload a file it will create 3 records.

Content Version -- where the version of the file stores.
ContentDocument is the parent object of ContentDocumentId, ContentVersion where it can store the versions of the file.
ContentDocumentLink -- It will be the link between the Parent object [LinkedEntityId] and the ContentDocument object

To achieve our task we need to have the link of the file and it is should be download url.

ContentDistribution Object
Represents information about sharing a document externally. 

First when ever a ContentDocumentLink record is created we need to make the record Visible to all users.

trigger MakeFileVisible on ContentDocumentLink (before insert) {
for(ContentDocumentLink l:Trigger.new) {
       l.Visibility='AllUsers';
}
}

and after the ContentDocumentLink is created we can create the ContentDistribution record.

trigger CreateDistribution on ContentDocumentLink (after insert) {
Set<Id> CId = new Set<Id>();
list<ContentDistribution> lstCD = new list<ContentDistribution>();
for(ContentDocumentLink Link : Trigger.new)
{
    CId.add(Link.ContentDocumentId); 
}
if(!CId.isEmpty())
{
   List<ContentVersion> file = new List<ContentVersion>([SELECT Id, Title,ContentDocumentId FROM ContentVersion WHERE ContentDocumentId IN :CId]);
 for(ContentVersion CV: file)
{

ContentDistribution CD = new ContentDistribution();
         CD.Name = CV.Title;
         CD.ContentVersionId = CV.Id;
        CD.PreferencesAllowViewInBrowser = true;
       lstCD.add(CD);
}

 insert lstCD;
} }

After this we need to create Dataraptor to extract the content distribution link

Image
In output tab from extract json path select the DistributionPublicUrl and Name map with output json path

Use this DataRaptor as a data source to the flexcard and use data table element to display the link and the name of the document.

This process is used when you are uploading a file to the standard file relatedlist.

If you fileupload element in flow or in Omnistudio with out apex triggers we can create ContentDistribution record by using dataraptors or create record element in flow.

Note: The above mentioned code is not written according to salesforce best practice. Just for basic understanding use the code.

Vlocity Facts #01 | OmniStudio DataRaptors

DataRaptor is a mapping tool that  you can use to read, transform, and write Salesforce data. For Example. In each interaction with a digital customer  or business process, the system needs to extract the data in order to display it. If the user modifies this data or enters new data, they also need to be saved. This is where we use OmniStudio DataRaptors.  Where to use DataRaptors? Retrieving Data:   OmniScript calls  DataRaptor Extract (via the integration procedure) to read the data from Salesforce. For example, OmniScript editing an account should display data such as account name, phone number, website, and so on. Manipulating data: OmniScript captures modified and new data based on user input. For example, an agent changes the  phone number of an account. Save Data:   OmniScript calls DataRaptor Load (via the integration procedure) to write the data back to Salesforce. For example, the updated account phone number is saved back to the Account rec...

Vlocity Facts #34 || Getting the details from the URL in a FlexCard and an Omniscript

Image
 1.The parameters in the URL must be in the format c__Node, followed by their values, in order to extract the parameters from the URL. For example: If you need to show different layout or different set of actions for community users and salesforces users you can pass different parameters in URL. For Community Portal Pass Community or any other reference value in ' c__Type '. https://salesforce.lightning.force.com/lightning/cmp/ omnistudio__vlocityLWCOmniWrapper?c__target=c%3ApHXTestFlexCard&c__tabIcon=custom%3Acustom18& c__Type =Community  For Salesforce Users Pass Salesforce or any other reference value in ' c__Type '. https://salesforce.lightning.force.com/lightning/cmp/ omnistudio__vlocityLWCOmniWrapper?c__target=c%3ApHXTestFlexCard&c__tabIcon=custom%3Acustom18& c__Type =Salesforce  2. We can get the value as {Params.c__Parameter} from the FlexCard and we can execute different actions based on the input. 3. From the omniscript,  we can retrieve ...

Vlocity Facts #44 || Communication between Omniscript and Flexcard [Pub/Sub]

Image
Flexcards have the ability to trigger and listen to two kinds of events: Custom and Pubsub events . Custom Events: Facilitate the transmission of information between a child and its parent. This can occur between a child Flexcard and its parent Flexcard, or between an element and the Flexcard to which it belongs. Pubsub Events: Allows communication between two separate components. This could occur between two separate Flexcards on the same Lightning page, known as sibling Flexcards, or between a Flexcard and an Omniscript.  In this post I will discuss about Pub/Sub event. Consider we have omniscript and flexcard individually on home page when an update happens we need to show those details in flexcard. To achieve this we can use pub/sub event. Step 1: Create a omniscript according to your requirement. I'm trying to create Contact record by using Step element and data raptor post action. Now to trigger the flexcard we need to configure the messaging frame work when an update happen...
