Use Case:
Write a trigger, if the owner of an account is changed then the owner for the related contacts should also be updated.
(this can happen if a user leaves a company, then it is required to update the owner field for all the accounts and contacts he/she owns)
// Since we need to perform updation on Contact instead of Account, so we are going to use 'After Update'trigger AccountTrigger on Account (after update) {if(Trigger.isUpdate && Trigger.isAfter) {List<Id> accountIds = new List<Id>();// To handle bulk operations, traverse through each account which is updated// verify if the Owner is changed or not then add its ID in 'accountIds'.for(Account account : Trigger.new) {if(account.OwnerId != Trigger.oldMap.get(account.Id).OwnerId) {accountIds.add(account.Id);}}// check if at least 1 account was updated with new ownerif(accountIds.size() != 0) {// Get list of all the contacts whose account's owner was changed.List<Contact> contacts = [Select Id, OwnerId, AccountIdFrom ContactWhere AccountId IN :accountIds];// Get the Owner Id value from newMap of Accounts and update the contact's Ownerfor(Contact con : contacts) {con.OwnerId = Trigger.newMap.get(con.AccountId).OwnerId;}update contacts;}}}
Test Class: We will create an account and a contact (keeping the owner same). Then update the account owner to some new user and verify that the contact owner should also get updated to new user.
@isTestprivate class AccountTriggerTest {// Create test data in 'testSetup'@testSetupstatic void testData() {// Create instance of a standard userProfile standardProfile = [Select Id, Name From Profile Where Name='Standard User'];User standardUser = new User(Alias = 'standt', Email='standarduser@testclasses.com',EmailEncodingKey='UTF-8', LastName='TestUser', LanguageLocaleKey='en_US',LocaleSidKey='en_US', ProfileId = standardProfile.Id,TimeZoneSidKey='America/Los_Angeles', UserName='standarduser@testclasses.com');// Create Account and Contact using run as the above user.System.runAs(standardUser) {Account acc = new Account(Name='TestAccount');insert acc;Contact con = new Contact(LastName='TestContact', AccountId=acc.Id);insert con;}}// Positive test case// 1.

Code Coverage: 100%
But it is also worked for me on Before Update Trigger
Hi Nitesh,
Not sure your logic working.I have updated some piece of code to work.
trigger UpdateOwnerofChildswhenParentOwnerChange on Account (after update) {
if(Trigger.isUpdate && Trigger.isAfter) {
List accountIds = new List();
List conUpdate = new List();
// To handle bulk operations, traverse through each account which is updated
// verify if the Owner is changed or not then add its ID in ‘accountIds’.
for(Account account : Trigger.new) {
if(account.OwnerId != Trigger.oldMap.get(account.Id).OwnerId) {
accountIds.add(account.Id);
}
}
system.debug(‘accpount iddddddd’+accountIds);
// check if at least 1 account was updated with new owner
if(accountIds.size() != 0) {
// Get list of all the contacts whose account’s owner was changed.
List contacts = [Select Id, OwnerId, AccountId
From Contact
Where AccountId IN :accountIds];
system.debug(‘contacts’+contacts);
// Get the Owner Id value from newMap of Accounts and update the contact’s Owner
for(Account acc :Trigger.new ){
system.debug(‘new owner id ‘+acc.OwnerId);
for(Contact con : contacts) {
Contact cont = new Contact();
if(acc.id==Con.accountId){
cont.OwnerId = acc.OwnerId;
cont.AccountId=acc.id;
cont.id=con.id;
conUpdate.add(cont);
}
}
}
system.debug(‘cons update’+conUpdate);
update conUpdate;
}
}
}
Nice Content. Good Work. 🙂
