Relating Contacts from Invitees via Trigger

I want to dumb down the multi person calendar events in Salesforce so a Salesperson can go to the invitees on the bottom and just enter all the people - users and contacts in one place.

If one adds contacts there, the event does not show in the Contact's related list. The EventRelation field IsParent defaults to FALSE, but updating it to TRUE makes this appear in the Contact's related lists.

Are there other considerations I am missing?

My trigger is below. One thing I can't do yet is limit my query to related contacts. Can't use LIKE '003%' in the id query.

Also, it doesn't seem to be updating. Am I missing the update...


  
trigger EventAttendeeCollector2 on Event (after insert, after update) {

    For (Event EVT:trigger.new){

        List <eventRelation> Erelates =[select RelationId from eventRelation where eventID=: EVT.id and IsInvitee = TRUE and IsParent=False]; 

        system.debug('ERELATES______________________________________'+ERELATES);

       for (eventRelation Link:Erelates){
           link.isparent=true;
           }

    }

}

Hi,

As salesforce best practices does not allow us to use SOQL inside the for loop so i have modified your trigger code and you are also missing an Update statement.
Please replace your trigger code from below code :
  
trigger EventAttendeeCollector2 on Event (after insert, after update) {
	List<EventRelation> eventRelList = new List<EventRelation>();
	eventRelList = [Select RelationId from EventRelation where eventID IN :trigger.new and IsInvitee = TRUE and IsParent=False];
	
	for(EventRelation rel : eventRelList){
		rel.IsParent = true;
	}
	update eventRelList;
}

Let me know if you have any issues with this.

Thanks,
Abhishek

Thanks! Cleaner.
Do you know how I'd filter out to only query Contact EventRelation and not Users?
jaw999jaw999
It did not update the IsParent value. It finds them, it lists to DML rows, but the value doesn't change. hmm
Abhishek BansalAbhishek Bansal
I did not get your point.
Can you please explain it more clearly ?
jaw999jaw999
It's not doing any change to the EventRelation. They retain the value of FALSE for IsParent.

To investigate, I added another debug after the update eventRelList; line. It shows:
  
08:38:17.272 (272504803)|USER_DEBUG|[14]|DEBUG|ERELATES__________updated?____________________________(EventRelation:{RelationId=003J000001FHLgFIAX, Id=0REJ00000026BZUOA2, IsParent=true}, EventRelation:{RelationId=003J000001FHLgUIAX, Id=0REJ00000026BZTOA2, IsParent=true})

So isParent = True. But when I do an export of the EventRelations using the Data Loader IsParent=false. Is something not being committed?
Abhishek BansalAbhishek Bansal
There may be some triggers on Event Relation which are running after this debug statement.
So please go through the debug log from top to bottom and check which triggers are running after this debug statement.
Your Event Relation is being updated once againg during the same context tht is why it is showing still false.

Please go through your debug log once again.

Abhishek.

There is a trigger that updates the EVent after, which then re-runs this trigger. In the debug for this second run, the first query finds no records. But no updates are made to eventRelations, only to the Event and certain parents. Also, this only runs on update, not on insert.
jaw999jaw999
And to be extra clear, I deactivated all EVent triggers so only this one runs and I get the same non update result every update. Debug logs show 2 rows returned, then show the IsParent is True.

Thanks for your help. It appears to be possible per this page: https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_objects_eventattendee.htm (https://developer.salesforce.com/docs/atlas.en-us.api.meta/api/sforce_api_objects_eventattendee.htm" target="_blank)

But we're seeing something stop it.
Trying it with their LIMIT of 1 doesn't make a difference.

How about pushing the action into an @future method? 
Trigger:
  
trigger EventAttendeeContactConnectorPusher on Event (before insert) {
    
     List<EventRelation> eventRelList = [SELECT Id, isParent, isInvitee FROM EventRelation WHERE EventId IN :trigger.new 
                                         AND isInvitee = true and isParent = false];
    
  	Set<Id> eventRelSet = (new Map<Id,EventRelation>(eventRelList)).keySet();
    EventAttendeeContactConnectorHandler.EventAttendeeContactConnector(eventRelSet);
    
}

One error on code - loop variable must be type Id ?
  
public class EventAttendeeContactConnectorHandler {
    
    
    @future
    public static void EventAttendeeContactConnector(set <id> relations) {
        
        for (EVentRelation rel: relations){
            rel.isParent=true;
        }
        update relations; 
    }

}

        for (EVentRelation rel: relations){
            rel.isParent=true;
        }
        //update relations; 
        Database.update(relations,false);
    
    }

}

The @fututre method is working.
