Apex Trigger on Contact to Update Related Events

Hi all, I have had some trouble trying to create a trigger that updates a field on related event records whenever a specific contact field is updated. I tried using a map of lists, but have found that a can't add an Event type as the value of the list. I wanted to make this map to link all updating contacts to their related events. Then, I would have to find a way to loop through the map, updating the event field. Here is my code:

Trigger IncrementValue on Contact (before update) {

    //Create a list of all updating contact IDs
    List<Id> contactIds = new List<Id>();
    for(Contact con : Trigger.new) {
        contactIds.add(con.Id);
    }
    
    //Create a map of all updating contact IDs and their related event IDs
    Map<Id, List<Event>> contactEvents = new Map<Id, List<Event>>();
    
    for(Event ev : [SELECT WhoId FROM Event WHERE WhoId IN :contactIds]) {
        if(contactEvents.containsKey(ev.WhoId)) {
            List<Event> eventId = contactEvents.get(ev.WhoId);
            eventId.add(ev.Activity_ID__c);
            contactEvents.put(ev.WhoId, eventId);
        }
        else {
            contactEvents.put(ev.WhoId, new List<Event> {ev.Activity_ID__c});
        }
    }
    
    List<Id> eventUpdate = new List<Id>();
    
    for(Contact con : Trigger.new) {
        if(contactEvents.containsKey(con.Id)) {
            return; //increment sales (Need help looping through map)
        }
    }
}

Here are my errors:

eventId.add(ev.Activity_ID__c); - Method does not exist or incorrect signature: void add(String) from the type List<Event>

contactEvents.put(ev.WhoId, new List<Event> {ev.Activity_ID__c}); - 
Initial expression is of incorrect type, expected: Event but was: String

Thank you for any help and will obviously answer any questions if my explanation was confusing!

Following are the updated Trigger and the Test class.

Trigger: 
Trigger IncrementSales on Contact (before update) {
    //Create a list of all updating contact IDs
    List<Id> contactIds = new List<Id>();
    for(Contact con : Trigger.new) {
        contactIds.add(con.Id);
    }
    
    //Create a map of all updating contact IDs and their related event IDs
    Map<Id, List<Event>> contactEvents = new Map<Id, List<Event>>();
    
    for(Event ev : [SELECT WhoId, Sales__c FROM Event WHERE WhoId IN :contactIds]) {
        System.debug('Line 13: '+contactEvents.size()); // This will always be 0 because we aren't adding anything to contactEvents before this..
        if(contactEvents.containsKey(ev.WhoId)) {
            List<Event> eventId = contactEvents.get(ev.WhoId);
            eventId.add(ev);
            contactEvents.put(ev.WhoId, eventId);
        }
        else {
            contactEvents.put(ev.WhoId, new List<Event> {ev});
        }
    }
    //Update this list at the end.
    List<Event> eventChanges = new List<Event>();
    
    for(Contact con : Trigger.new) {
        Contact oldCon = Trigger.oldMap.get(con.Id);
        if(con.Sales__c != oldCon.Sales__c) {
               if(contactEvents.containsKey(con.Id)) {
                   for(Event ev : contactEvents.get(con.Id)) {
                       eventChanges.add(ev);
                   }
                   for(Event ev : eventChanges) {
                       ev.Sales__c = ev.Sales__c + (con.Sales__c - oldCon.Sales__c);
               }
           }
        }
    }
    update eventChanges;
}

Test Class: 
@isTest
public class TestIncrementSales {
    public static testMethod void updateContact() {
        Contact contactNew = new Contact(FirstName = 'Dave', LastName = 'Matthews', Sales__c = 10); //Old Sales__c
        insert contactNew;
        
        Contact retCont = [SELECT Id, FirstName, LastName, Sales__c FROM Contact WHERE Id =:contactNew.Id];
        System.assertEquals('Dave', retCont.FirstName);
        System.assertEquals('Matthews', retCont.LastName);
        System.assertEquals(10, retCont.Sales__c);
        
        Event eventNew = new Event(Subject = 'Meeting Test', WhoId = contactNew.Id, ActivityDate = system.today(),
                                   StartDateTime = datetime.newInstance(2019, 6, 28, 12, 00, 0),
                                   EndDateTime = datetime.newInstance(2019, 6, 28, 14, 00, 0), Type = 'Meeting - Lunch', Sales__c = 0);
        insert eventNew;
        
        Event retEvent = [SELECT Id, Subject, WhoId, ActivityDate, Type, Sales__c FROM Event WHERE Id =: eventNew.Id];
        System.assertEquals('Meeting Test', retEvent.Subject);
        System.assertEquals(contactNew.Id, retEvent.WhoId);
        System.assertEquals('Meeting - Lunch', retEvent.Type);
        System.assertEquals(0, retEvent.Sales__c);
        
        contactNew.Sales__c = 25; //New Sales__c
        contactNew.SalesConnect__YTD_Sales_with_Partnerships__c = 15;
        update contactNew;
        
        retEvent = [SELECT Sales__c FROM Event WHERE WhoId =:contactNew.Id];
        retCont = [SELECT Sales__c FROM Contact WHERE Id =:contactNew.Id];
        System.assertEquals(15, retEvent.Sales__c);
        System.assertEquals(25, retCont.Sales__c);
    }
}

However I have some points that I want to raise in your trigger.
  • The reason that you weren't seeing the changes in the Event.Sales__c because you are not updating the event list after making the changes and adding it to the list. That explains line 38 in the trigger.
  • Like I mentioned before, on line 13 - that if condition will never be true. You need to do the appropriate to populate the contactEvents map. Only then it'll get into that IF block. I couldn't do it because am not fully aware of the requirement.
  • The test coverage as I post this, is 85%.
  • I added a fair number of assert statements, the more the better. 
Hope it helps. :)

Hey Mitch, I have a few questions..
  1. In the first for loop on line 11, the first if condition will never be true because the contactEvents will be empty at that point, right?
  2. On line 18, I think it should be - contactEvents.put(ev.WhoId, new List<Event>(ev)); - because the map should be taking an Id and a list of events. In your code, you're giving ev.Activity_Id__c to the list, giving a field to that list, correct me if am wrong.
  3. What is the data type of Activity_Id__c?
Deepali KulshresthaDeepali Kulshrestha
Hi Mitch,

- I have gone through your problem and implemented it in my Org and your problem is that you are adding a string "ev.Activity_ID__c" to List of Event "eventId ".

I hope you find the above solution helpful. If it does, please mark as Best Answer to help others too.

Thanks and Regards,

Mitch MorrisonMitch Morrison
@Apuroop Thanks for the help!
1. I believe the if statement should be true if there are multiple events for a contact. The else statement adds the key, value record to the map for the first event change for a contact. After that, the if statement should just append any other events to the list in the map tied to the contact.
2. Yep, that makes sense
3. It is just an auto number, but it looks like I don't need it anyway

Here's my new code. There are no problems, but my test didn't work. I got the error - 'Invalid field Contact for Event'.

Trigger IncrementSales on Contact (before update) {

    //Create a list of all updating contact IDs
    List<Id> contactIds = new List<Id>();
    for(Contact con : Trigger.new) {
        contactIds.add(con.Id);
    }
    
    //Create a map of all updating contact IDs and their related event IDs
    Map<Id, List<Event>> contactEvents = new Map<Id, List<Event>>();
    
    for(Event ev : [SELECT WhoId, Sales__c FROM Event WHERE WhoId IN :contactIds]) {
        if(contactEvents.containsKey(ev.WhoId)) {
            List<Event> eventId = contactEvents.get(ev.WhoId);
            eventId.add(ev);
            contactEvents.put(ev.WhoId, eventId);
        }
        else {
            contactEvents.put(ev.WhoId, new List<Event> {ev});
        }
    }
    
    for(Contact con : Trigger.new) {
        Contact oldCon = Trigger.oldMap.get(con.Id);
        if(con.Sales__c != oldCon.Sales__c) {
               if(contactEvents.containsKey(con.Id)) {
                   List<Event> eventChanges = new List<Event>();
                   for(Event ev : contactEvents.get(con.Id)) {
                       eventChanges.add(ev);
                   }
                   for(Event ev : eventChanges) {
                       ev.Sales += (con.Sales__c - oldCon.Sales__c);
               }
           }
        }
    }
}

Thanks again!!

Glad I cloud help. What data type is this new Sales__c field on both Contact and Event? Maybe I could write a test class in my dev.
Mitch MorrisonMitch Morrison
They are both currencies. Here is the test that I ran:

@isTest
Public class TestIncrementSales {
    Static testMethod void updateContact() {
    Contact contactNew = new Contact();
    contactNew.FirstName = 'Dave';
    contactNew.LastName = 'Matthews';
    contactNew.Sales__c = 10;
    insert contactNew;
    Event eventNew = new Event();
    eventNew.Subject = 'Meeting Test';
    eventNew.WhoId = contactNew.Id;
    eventNew.ActivityDate = system.today();
    eventNew.StartDateTime = 
        datetime.newInstance(2019, 6, 28, 12, 00, 0);
    eventNew.EndDateTime = 
        datetime.newInstance(2019, 6, 28, 14, 00, 0);
    eventNew.Type = 'Meeting - Lunch';
    eventNew.Sales__c = 0;
    insert eventNew;
    contactNew.SalesConnect__YTD_Sales_with_Partnerships__c = 15;
    update contactNew;
    }
}

The Sales__c for contact should be $15 after the test and the Sales__c for the event should be $5 (which is the change in sales for the contact)

Thanks!

Mitch MorrisonMitch Morrison
Thanks! I will take a look at this and let you know if it works. For line 13, the logic I am trying to figure out is this:

For every event that is tied to an updating contact:
     add a key, value (contact ID, list<event>) pairing to the map
     if the contact is already in the map, then add the next event to the list (this would happen for contacts tied to multiple events)

Hopefully, that makes more sense. I don't have much experience with using maps like this, so I really appreciate your help, Apuroop!
Mitch MorrisonMitch Morrison
Hi Apuroop! I implemented your changes and the test worked for a single record update. I am not trying to develop a full test which includes:
- Multiple changes contacts
- Multiple events attached to the contacts
This will hopefully prove that the map lists work properly and then we can push the trigger to our SF. I tried a test will multiple changes contacts but only one event attached to each. The test passed, but when I ran it in 'execute anonymous', I got this error: System.QueryException: List has more than 1 row for assignment to SObject

Here is the test (all I did was copy/paste your test for another contact & event):

public class TestIncrementSales {
    public static testMethod void updateContact() {
        //Contact 1
        Contact contactNew = new Contact(FirstName = 'Dave', LastName = 'Matthews', Sales__c = 10); //Old Sales__c
        insert contactNew;
         
        Contact retCont = [SELECT Id, FirstName, LastName, Sales__c FROM Contact WHERE Id =:contactNew.Id];
        System.assertEquals('Dave', retCont.FirstName);
        System.assertEquals('Matthews', retCont.LastName);
        System.assertEquals(10, retCont.Sales__c);
        
        //Contact 2
        Contact contactNew2 = new Contact(FirstName = 'Clay', LastName = 'Matthews', Sales__c = 100000); //Old Sales__c
        insert contactNew2;
         
        Contact retCont2 = [SELECT Id, FirstName, LastName, Sales__c FROM Contact WHERE Id =:contactNew2.Id];
        System.assertEquals('Clay', retCont2.FirstName);
        System.assertEquals('Matthews', retCont2.LastName);
        System.assertEquals(100000, retCont2.Sales__c);
        
        //Event 1
        Event eventNew = new Event(Subject = 'Meeting Test', WhoId = contactNew.Id, ActivityDate = system.today(),
                                   StartDateTime = datetime.newInstance(2019, 6, 28, 12, 00, 0),
                                   EndDateTime = datetime.newInstance(2019, 6, 28, 14, 00, 0), Type = 'Meeting - Lunch', Sales__c = 0);
        insert eventNew;
         
        Event retEvent = [SELECT Id, Subject, WhoId, ActivityDate, Type, Sales__c FROM Event WHERE Id =: eventNew.Id];
        System.assertEquals('Meeting Test', retEvent.Subject);
        System.assertEquals(contactNew.Id, retEvent.WhoId);
        System.assertEquals('Meeting - Lunch', retEvent.Type);
        System.assertEquals(0, retEvent.Sales__c);

        Event retEvent2 = [SELECT Id, Subject, WhoId, ActivityDate, Type, Sales__c FROM Event WHERE Id =: eventNew2.Id];
        System.assertEquals('Meeting Test 2', retEvent2.Subject);
        System.assertEquals(contactNew.Id, retEvent2.WhoId);
        System.assertEquals('Meeting - Breakfast', retEvent2.Type);
        System.assertEquals(50000, retEvent2.Sales__c);

        contactNew.Sales__c = 25; //New Sales__c
        update contactNew;
        
        contactNew2.Sales__c = 500000; //New Sales__c
        update contactNew2;

        retEvent = [SELECT Sales__c FROM Event WHERE WhoId =:contactNew.Id];
        retEvent2 = [SELECT Sales__c FROM Event WHERE WhoId =:contactNew2.Id];
        retCont = [SELECT Sales__c FROM Contact WHERE Id =:contactNew.Id];

        System.assertEquals(500000, retCont2.Sales__c);
    }
}


Thanks for your help!!!

Hello Mitch,

The error was that you are trying to query more than 1 record on line 52. In this test class, you are creating an Event1 for Contact1. Same goes with Event2 for Contact2, correct?

If the above statement is correct, you need to change the WhoId = contactNew.Id of eventNew2 to WhoId = contactNew2.Id. You are assigning the first contact to the second event. That's the reason it's pulling more than one record on line 52.

After this, change the assert statement on 42 - System.assertEquals(contactNew2.Id, retEvent2.WhoId);
Mitch MorrisonMitch Morrison
Thanks! I thought I had changed everything but I missed that. It worked this time!
Mitch MorrisonMitch Morrison
Apuroop,

So I want to be able to assign a contact to multiple events. If I do this, I'll get the same error as above. If there are multiple events connected to the contact, I want the trigger to update all of them. Is there just something I need to change in the test to handle multiple list rows for an object? Or do we need to rethink the trigger?

Thanks!!
ApuroopApuroop
I think the trigger is working just fine. I guess you could add some more events to the contacts and test it with assert statements.

Try this:
  
@isTest
public class TestIncrementSales {
    public static testMethod void updateContact() {
        List<Contact> contactList = new List<Contact>();
        List<Event> eventList = new List<Event>();
        //Contact 1
        Contact contactNew = new Contact(FirstName = 'Dave', LastName = 'Matthews', Sales__c = 10); //Old Sales__c
        contactList.add(contactNew);
        //Contact 2
        Contact contactNew2 = new Contact(FirstName = 'Clay', LastName = 'Matthews', Sales__c = 100000); //Old Sales__c
        contactList.add(contactNew2);
        insert contactList;
        
        //Event 1
        Event eventNew1 = new Event(Subject = 'Meeting Test 1', WhoId = contactNew.Id, ActivityDate = system.today(),
                                   StartDateTime = datetime.newInstance(2019, 6, 28, 12, 00, 0),
                                   EndDateTime = datetime.newInstance(2019, 6, 28, 14, 00, 0), Type = 'Meeting - Lunch', Sales__c = 0);
        eventList.add(eventNew1);
        //Event 2
        Event eventNew2 = new Event(Subject = 'Meeting Test 2', WhoId = contactNew.Id, ActivityDate = system.today(),
                                   StartDateTime = datetime.newInstance(2018, 10, 28, 12, 00, 0),
                                   EndDateTime = datetime.newInstance(2018, 10, 28, 14, 00, 0), Type = 'Meeting - Breakfast', Sales__c = 50000);
        eventList.add(eventNew2);
        //Event 3
        Event eventNew3 = new Event(Subject = 'Meeting Test 3', WhoId = contactNew2.Id, ActivityDate = system.today(),
                                   StartDateTime = datetime.newInstance(2019, 6, 28, 12, 00, 0),
                                   EndDateTime = datetime.newInstance(2019, 6, 28, 14, 00, 0), Type = 'Meeting - Lunch', Sales__c = 200);
