Set Contact as primary if one does not exist

Hello All,
I have the following code that only allows a single Primary Contact per Account.  But what I would like to do is set the newly created Contact as Primary(Primary__c==True) if one does not exist.  Can I utilize my existing Class or do I have to create a new one
Thank you for your time and help.

Hello Michael,

You can try below code, which will also update the primary contact in case of insert, update and delete. Apex trigger is like: 
trigger PrimaryContactTrgr on Contact (after insert, after update,after delete) {
    // Assign values of trigger new list to helper class variable
    PrimaryContactHelper.newContactsList = trigger.new;
     // Assign values of trigger old list to helper class variable
    PrimaryContactHelper.oldContactsList = trigger.old;
    // Assign values of trigger new map to helper class variable
    PrimaryContactHelper.newContactsMap = trigger.newMap;
    // Assign values of trigger old map to helper class variable
    PrimaryContactHelper.oldContactsMap = trigger.oldMap;
    if(trigger.isAfter)
    {
      //insert trigger
        if(trigger.isInsert)
        {
          //calling helper class method 
            PrimaryContactHelper.primaryContactactive();
        }
        //update trigger
        if(trigger.isUpdate)
        {
          //calling helper class method
            PrimaryContactHelper.updateContact();
        }
         if(trigger.isDelete)
         {
          //calling helper class method
            PrimaryContactHelper.deleteContact();

Thank you both for your replies.  I hope you both had a good holiday.  Neetu I have a question about the helper class.  Do I need to add add new custom fields? I see the following fields; PrimaryContact__c,Secondary_Contact__c,Active_Contact__c.

Bhaswanthnaga, I will modify my existing code as you suggested and let you know how it works.

Thnaks again to you both.
M
Michael Hedrick 2Michael Hedrick 2
Bhaswanthnaga,
Is the syntax below correct?
 [SELECT Id,(SELECT Id, Id FROM Contacts WHERE Primary__c=true)

Also, do I need to create a new field on the Account Object? PrimaryContact__c?

Thanks
Bhaswanthnaga vivek vutukuriBhaswanthnaga vivek vutukuri

sorry that was [SELECT Id,(SELECT Id, recordtypeId FROM Contacts ..............

Yes, you have to create a new field if you want to maintain PC informaiton on Account
Michael Hedrick 2Michael Hedrick 2
Thnaks Bhaswanthnaga,  is 'accountToUpdate' supposed to be  anew list?
Cheers,
M
Bhaswanthnaga vivek vutukuriBhaswanthnaga vivek vutukuri
Yes
Michael Hedrick 2Michael Hedrick 2
Hey Bhaswanthnaga,
What would the list look like? And where would I insert the code since this has an Else statement? 
  
Map<Id,Set<Id>> NewContactRtMap = new Map<Id,Set<Id>>();
      for(Account a : [SELECT Id,(SELECT Id, recordtypeId FROM Contacts WHERE Primary__c=true) FROM Account WHERE Id Not In :accountIdToNewContactRtMap.keySet()])

Thanks,
M
Michael Hedrick 2Michael Hedrick 2
Still having an issue:
Variable does not exist: ac    - line 34 
Variable does not exist: newContactRtMap   - line 38

Any help is appreciated.

Use the above code
Michael Hedrick 2Michael Hedrick 2
Thanks Bhaswanthnaga.
I am getting an error at line 35.  ' newAccountRtMap.add(ac.Id, ac); '
Do we need to include the ac.id?
 
Michael Hedrick 2Michael Hedrick 2
error is:
Method does not exist or incorrect signature: void add(Id, Account) from the type Map<Id,Account>
Bhaswanthnaga vivek vutukuriBhaswanthnaga vivek vutukuri
use newAccountRtMap.put(ac.Id,ac)
Michael Hedrick 2Michael Hedrick 2
Hey Bhaswanthnaga.  That fixed the error but the code did not work as expected and I know why but not sure how to corret.t 
} else {
                    for(Account ac : [SELECT Id,(SELECT id,email,RecordTypeId FROM Contacts WHERE Primary__c=true) FROM Account WHERE Id not in :accountIdToNewContactRtMap.keySet()])
                    {
                        ac.contacts[0].Primary__c=true;
                        ac.Primary_Contact_Email_Address__c = ac.Contacts[0].email;
                        newAccountRtMap.put(ac.Id,ac);
                    }

If there is not a Primary Contact for an Account and a user creates a contact.  That contact needs to be the set as the Primary.  Which means even if the user does not select the checkbox I nned to select the Primary checkbox and make the newly created Contact the Primary Contact.
The code as it stands is only looking for Contacts where the Primary is already checked and this may not be the case.  If you have any other thoughts let me know.  Thnaks for all your help.

Not sure why have you changed the code that I have kept in first place please use that code.

else {
           c.Primary_c = true;
            Account a = new Account();
            a.Id = c.AccountId;
            a.PrimaryContact__c = c.Id;
            accountToUpdate.add(a);
            newAccountRtMap.put(ac.Id,ac);

         }
Michael Hedrick 2Michael Hedrick 2
Apologies.  Trying to make too make corrections at once.  So take out the  
for(Account ac : [SELECT Id,(SELECT id,Primary_c,email,RecordTypeId FROM Contacts WHERE Primary__c=true) FROM Account WHERE Id not in :accountIdToNewContactRtMap.keySet()])

 
Michael Hedrick 2Michael Hedrick 2
What type of field is  a.PrimaryContact__c?
Bhaswanthnaga vivek vutukuriBhaswanthnaga vivek vutukuri
sorry that is ac.Primary_Contact_Email_Address__c  = c.email;
Michael Hedrick 2Michael Hedrick 2
No worries.  You're trying to help and I am trying to understand.
So the for loop stys correct?

for(Account ac : [SELECT Id,(SELECT id,email,RecordTypeId FROM Contacts WHERE Primary__c=true) FROM Account WHERE Id not in :accountIdToNewContactRtMap.keySet()])
Bhaswanthnaga vivek vutukuriBhaswanthnaga vivek vutukuri
NO for loop wont't stay in the else part just use the code what I have kept  
for(Contact c : trgNew)
            {
                if(existingContactRtMap.containsKey(c.AccountId) && existingContactRtMap.get(c.AccountId).contains(c.RecordTypeId))
                {
                    c.addError('There is already a primary contact for this record type.');
                } else {
                   
                        c.Primary_c = true;
            Account a = new Account();
            a.Id = c.AccountId;
           ac.Primary_Contact_Email_Address__c  = c.email;
            newAccountRtMap.put(ac.Id,ac);
                   

                }
            }

ok. no error.Yes! 
I will test it now and let you know.
Thanks for your patuence and help.

Bhaswanthnaga - Code is still preventing a secong Primary conact to be added but if there is not a Primary it is not setting the Primary checkbox....
Michael Hedrick 2Michael Hedrick 2
Is this the issue ?   
if(!accountIdToNewContactRtMap.isEmpty())

The list is empty so it is never goes into the If statements correct?

that's not issue, we have to use if condition
