**i am trying to do upsert operatiob on my timesheet__c object
Trigger is on Leave__c object which is trying to match the date
if date is same then check for employee name
and if name found on timeSHeet__c object then just update
if not found then Crate an new Record on TimeShett__c object **
i having two Objects
child-Leave__c;
Parent-TimeSheet__c;
when ever i insert a record on leave object
1.it should check whether on same date is there any timesheet record
here the trigger
'''
trigger CheckTime on LEAVE__c (after insert) {
list<id> idList=new list<id>();
for(Leave__c ls:Trigger.new)
{
idList.add(ls.id); //adding new record id
}
list<Leave__c> lslist=[select id ,Date__c,Hours__c,Employee__c,TimeSheet_Lookup__r.Date__c,TimeSheet_Lookup__r.Employee__c,TimeSheet_Lookup__r.Hours__C from LEAVE__c where id IN:idList]; //fetching new record using child to parent relationship
list<TimeSheet__c> tslist=new list<TimeSheet__c>();

{
if(ls.Date__c==ls.TimeSheet_Lookup__r.Date__c)//checking if date is matching

I'm new to salesforce and I'm trying to learn more. Currently I'm stuck at a point where I don't know what to do further. Kindly point me in the right direction. Any help is appreciated.
So what im trying to do is to compare lastnames to find duplicates when the record is being created and if a duplicate is found then instead of creating it as a new record it should be merged with existing record.
So to achieve the task I have wrote the following trigger handler:
public class LeadTriggerHandler {
public static void duplicateMerge(){
List<Lead> leadList = [SELECT Id,Name, Email, Phone, FirstName, LastName FROM Lead];
List<Lead> leadTrigger = Trigger.new;
for(Lead leadVarTrigger : leadTrigger){
for(Lead leadVar : leadList){
//System.debug(leadVar.LastName + '==' + leadVarTrigger.LastName);
if(leadVarTrigger.LastName == leadVar.LastName)
{
//System.debug(leadVar.LastName + '==' + leadVarTrigger.LastName);
//leadVarTrigger.addError('This is a duplicate record');
Database.merge(leadVar, leadVarTrigger);
System.debug('Trigger Successful');
}
}
}
}
}
the following is my trigger:
trigger LeadTrigger on Lead (after insert) {
if(Trigger.isafter && Trigger.isInsert)
{
LeadTriggerHandler.duplicateMerge();
}
}
And when I try with after insert i get the following error:
LeadTrigger: execution of AfterInsert caused by: System.DmlException: Merge failed. First exception on row 0 with id 00Q5j00000ENUGVEA5; first error: INVALID_FIELD_FOR_INSERT_UPDATE, Unable to create/update fields: Name. Please check the security settings of this field and verify that it is read/write for your profile or permission set.: [Name] Class.LeadTriggerHandler.duplicateMerge: line 18, column 1 Trigger.LeadTrigger: line 5, column 1
And if i try with before trigger i get the following error for the same code:
LeadTrigger: execution of BeforeInsert caused by: System.StringException: Invalid id at index 0: null External entry point Trigger.LeadTrigger: line 5, column 1
Actually, according to your code, you are allowing the record to be created and saved to the database by using after insert. Your before insert failed because your handler class is referencing an Id, however, if you use before logic, the record isn't saved to the database yet, meaning it doesn't have an Id. With that being said, let's try the following. :)
The Trigger (Best practice is to have one trigger with all events):
trigger TestTrigger on Lead (before insert, before update, before delete, after insert, after update, after delete, after undelete) {
if(Trigger.isafter && Trigger.isInsert)
{
//Can't conduct DML operations with trigger.new or trigger.old
//So we will create a set and send this to our handler class
Set<Id> leadIds = Trigger.newMap.keySet();
LeadTriggerHandler.duplicateMerge(leadIds);
}
}
The Handler Class:
public class LeadTriggerHandler {
public static void duplicateMerge(Set<Id> idsFromTrigger){
//Querying the database for the records created during the trigger
List<Lead> leadTrigger = [SELECT Id, LastName FROM Lead WHERE Id IN: idsFromTrigger];
List<String> lastNames = new List<String>();
//This set is important as it prevents duplicates in our dml call later on
Set<Lead> deDupedLeads = new Set<Lead>();
List<Lead> leadsToDelete = new List<Lead>();
for (Lead l : leadTrigger){
//getting all of the Last Names of the records from the trigger
lastNames.add(l.lastName);
}
//We are querying the database for records that have the same last name as
//the records that were created during our trigger
List<Lead> leadList = [SELECT Id, Name, Email, Phone, FirstName, LastName FROM Lead WHERE LastName IN: lastNames];
for(Lead leadInTrigger : leadTrigger){
for(Lead leadInList : leadList){
if(leadInTrigger.LastName == leadInList.LastName){
//if the lead from the trigger has the same last name as a lead that
//already exists, add it to our set
deDupedLeads.add(leadInTrigger);
}
}
}
//add all duplicate leads from our set to our list and delete them
leadsToDelete.addAll(deDupedLeads);
delete leadsToDelete;
}
}
This handler has been bulkified in two ways, we removed the DML operation out of the loop and the code is able to process a scenario where someone mass inserts 1000s of leads at a time. Plus, rather than querying every lead record in your database, we only query for records that have the same last name as the records created during the insert operation. We advise using something more unique than LastName like Email or Phone as many people/leads can have the same Last Name. Hope this helps and have a blessed one.
Need some advise on how to populate a lookup field (contact) via apex trigger
I've created a lookup field called Contact__c on Idea object.
I would like to populate the Contact__c with the createdby User if it was originated from the web (CreatedBy.Contact.Account.Name == "Web Ideas") and leave it empty for internal idea creation.
I have read up and created the following trigger and was able to save and run. However, upon saving the idea record, i am getting an error : UpdateContactonComplaints: data changed by trigger for field Contact: id value of incorrect type: 005N0000000l9iMIAQ
trigger UpdateContactonComplaints on Idea (before insert, before Update) {
list<id> oid = new list<id>();
for(Idea o: trigger.new){
oid.add(o.id);
}
map<id, Idea> ExtendU = new map<id, Idea>(
[select CreatedbyID from Idea where id in: oid]);
for(Idea o: trigger.new){
o.Contact__c = ExtendU.get(o.id).CreatedbyID;
}
}
In the Trigger, the user id(id of the User who created the idea) is assigned to Contact custom lookup field).
So, it throws an error, data changed by trigger for field Contact: id value of incorrect type:
I created a custom object XtendedUser which has an id and Name.
I created a custom lookupfield on Opportunity called "XtendedUser__c" which links the opportunity to the corresponding XtendedUser record.
Now I made it so that the name of an opportunityowner corresponds to the name of an XtendedUser-record, so I want the trigger to autopopulate the custom lookup field "XtendedUser__c" on the opportunity with the id of the corresponding XtendedUser-record of which the name matches the name of the opportunityowner.
I never wrote a trigger, always worked with workflows and fieldupdates, but I've got to make this work. So if you could please help me with this? I would be extremely greatfull!
Thanks in advance
You should use a map to link the records and retrieve the value before the insert of a new record and before the update of an existing record. This technique will also allow you to bulk update all your records. It should be something like:
trigger ExtendedUser__c on Opportunity (before insert, before Update) {
list<id> oid = new list<id>();
for(opportunity o: trigger.new){
oid.add(o.id);
}
map<id, ExtendedUser__c> ExtendU = new map<id, ExtendedUser__c>(
[select name from ExtendedUser__c where id in: oid]);
for(opportunity o: trigger.new){
o.name = ExtendU.get(o.id).name;
}
}
I am having following requirement:
1) To get list of all the users for whome profile has been changed.
2) Then query on FRUP (It is a custom object) to retrieve all the records which are associated with the user whose profile is changed.(FRUP object will contain the list of all the records created by all the users on all the objects say Account, Opportunity)
3) Update FRUP.
For achieving this I wrote one trigger through which i am able to fetch list of all the users whose profile has changed which is as follows:
Trigger UserProfileTrigger on User (before update) {
List<User> usr = new List<User>();
Map<String,String> userMap = new Map<String,String>();
for(User u: Trigger.new){
//Create an old and new map so that we can compare values
User oldOpp = Trigger.oldMap.get(u.ID);
User newOpp = Trigger.newMap.get(u.ID);
//Retrieve the old and new profile
string oldProfileId = oldOpp.profileId;
string newProfileId = newOpp.profileId;
//If the fields are different, the profile has changed
if(oldProfileId != newProfileId){
System.debug('Old:'+oldProfileId);
System.debug('New :'+newProfileId);
usr.add(u);
System.debug('User :'+usr);
}
}
}
Also Following are the fields on custom object FRUP:
1)Owner
2)Name
3)Record ID
4)Folder ID
5)Created By
6)Last Modified By
any help/suggestions??
I'm not sure what field on the FRUP references the user Id it relates to, but you can loop through the FRUP object with something like this:
List<FRUP> frupToUpdate = new List<FRUP>();
for (FRUP f : [
Select
OwnerId,
Name, //etc.
UserId //the field that references the user Id
from FRUP
where userId = : usr]) {
//update field on FRUP, e.g. f.Name = 'New Name';
frupToUpdate.add(f);
}
This selects the FRUP records that relate to the users with changed profiles. It then updates a field on the record and adds the record to a list for updating. Note that this should be after your loop for(User u: Trigger.new). Then update the FRUP records that have changed:
update frupToUpdate;
I need a trigger that receives data from users (Bulk load of about 1000 records) and store them in a Salesforce database. The problem is that users can show up more than once in Trigger.new or even on a different batch. The custom object name is CBK_User and has an EXTERNAL_ID (unique) called USER_ID. In my code I check that the users does not yet exist in the database:
Map<String, CBK_User__c> users = new Map<String,CBK_User__c>
([select Id, USER_ID__c from CBK_User__c where USER_ID__c in : userIds]);
(userIds has the external ids of the Trigger.new objects)
When a I try to insert, it gives me the error:
DUPLICATE_VALUE, duplicate value found: USER_ID__c duplicates value on
record with id: a1QJ0000000HRd8"
How do I prevent duplicate values on bulk insert?
I've adapted your problem to this basic example (Exercise 2: Lead duplicate prevention)
You should clean first the "new" list from duplicated entries, and then clean from existing in db.
trigger CBK_UserDuplicatePreventer on CBK_User__c (before insert, before update) {
//Enter a map declaration to hold records which we will add,
// this will become a unique map, no duplicate values within it.
Map<String, CBK_User__c> cbkUserMap = new Map<String, CBK_User__c>();
//The next few lines loop across the array of records that are passed into
//the trigger in bulk fashion from any API or User Interface database operation.
//The goal of this loop is to ensure that there are no duplicates within
//the batch that we have received and to gather a list of externalIds that we will use later
for (CBK_User__c cbkUser : System.Trigger.new) {
/* Make sure we don't treat an externalId that
isn't changing during an update as a duplicate. */
if ((cbkUser.USER_ID__c != null) && (System.Trigger.isInsert ||
(cbkUser.USER_ID__c != System.Trigger.oldMap.get(cbkUser.Id).USER_ID__c))) {
// Make sure another new CBK_User__c isn't also a duplicate
if (cbkUserMap.containsKey(cbkUser.USER_ID__c)) {
cbkUser.USER_ID__c.addError('Another new CBK_User__c has the same USER_ID.');
} else {
cbkUserMap.put(cbkUser.USER_ID__c, cbkUser);
}
}
}
// Using a single database query, find all the CBK_User__c in
// the database that have the same USER_ID as ANY
// of the CBK_User__c being inserted or updated. */
for (CBK_User__c cbkUser : [SELECT USER_ID__c FROM CBK_User__c WHERE USER_ID__c IN :cbkUserMap.KeySet()]) {
CBK_User__c newCbkUser = cbkUserMap.get(cbkUser.USER_ID__c);
newCbkUser.USER_ID__c.addError('A CBK_User__c with this USER_ID already exists.');
}
}
