Hello,
I am new to salesforce and I would like to know how to create custom button to update record's field value on click.
Should I use lightning component + apex code or is it possible achieve it without code?

FieldName:  Times clicked
FieldValue = 0 + 1 time clicked // sObject_c.TimesClicked++

RollUp Contact to Account.
Account has Total_Amt__c field, Customer has Amount__c(Currency) field. 
Total_Amt__c field should show all sum of all values of Amount__c field of all chield reccord
(please explain critical lines in code)

        @auraEnabled public String RoleName{get;set;}
        @auraEnabled lookUpWrapper selItem{get;set;}
    }
    public class lookUpWrapper{
        public String objName {get;set;}
        public String text{get;set;}
        public String val{get;set;}
        public Object ObjRecord{get;set;}
    }

Below ti the method which convert the json to string.

 public class ASMWrapper{
        @auraEnabled public User userObj{get;set;}
        @auraEnabled public String RoleName{get;set;}
        @auraEnabled lookUpWrapper selItem{get;set;}
    }
    public class lookUpWrapper{
        public String objName {get;set;}
        public String text{get;set;}
        public String val{get;set;}
        public Object ObjRecord{get;set;}
    }

this method is getting the JSON. please help me parse it.

public static void  newAccRecord(String asmHierarchy){
        system.debug('string JSON '+asmHierarchy);
        System.debug('jason der' + JSON.deserializeUntyped(asmHierarchy));
        /*if(asmHierarchy.size() >0){
            for(object obj : asmHierarchy){
                system.debug('obj '+obj);
                //ASMWrapper asm = (ASMWrapper)obj;
                //system.debug('User ==> '+asm.asmObj.userObj);
            }
            System.debug(' ASMWrapper DONE @@@ '+asmHierarchy);
            System.debug('size of role '+asmHierarchy.size());
        }*/
       
    }

This is my FIRST trigger.
I want to create an "Event" after "Time Off Request" is Approved.
After approving, the following error message is showing...



Here is my trigger:

trigger TRTimeOffAfterUpdate on Time_Off_Request__c (after update) {

for (Time_Off_Request__c toEvent : Trigger.new) {
    if(toEvent.Status__c=='Approved'){
   // Event event = new Event
   Event ev= new Event 
   (
        OwnerId = toEvent.CreatedById,
        StartDateTime = toEvent.First_Day_Off__c,
        EndDateTime = toEvent.End_Time_Off__c,
        Subject = toEvent.Type__c,
        Description =  toEvent.Comments__c,
        ShowAs = 'Out of Office'
    );
    insert ev ;             
}
}
}

Any idea what is wrong?
Thanks

Account object has Acc_Satus__c  Field and Contact Object has Con_Status__c Field.
both Acc_Satus__c, Con_Status__c are picklist field with values: Open, Closed, InProgress.
Account Record Has Three Child Contact Records
1. Whenever Account record field is updated with Acc_Satus__c Piclist field as 'Closed', all Contact Con_Status__c field should be 'Closed'.
2. if Con_Status__c field in all three Contact record is selected as 'Closed' Account picklist Acc_Satus__c Field Should be 'Closed'.
give me a code with Helper class

RollUp Contact to Account.
Account has Total_Amt__c field, Customer has Amount__c(Currency) field. 
Total_Amt__c field should show all sum of all values of Amount__c field of all chield reccord
(please explain critical lines in code)

I want to create a trigger on Note object.
When a new note is created it will update a custom field on Case object with LastModifiedDate of New note.

My code is :

trigger UpdateLastModifiedDate on Note(after insert) {
    
     List<Case> caseUpdate = new List<Case>();
    for(Note n : Trigger.new){
        if(n.ParentId != null && n.ParentId.getSObjectType() == Case.sObjectType){
            Case cas=new Case(Id=n.parentId,Last_Modified_Date1__c=n.CreatedDate);
            caseUpdate.add(cas);

       } 
    }
    
    if(caseUpdate.size()>0){
        update caseUpdate;
    }
}

Can anyone explain Difference between Process Builder and Flows with example ? 
Thanks in Advance.

Hi All,

I want to display number of contacts associated with an account using triggers.

for this I had created a lookup field like noofcontacts__c in account  object. and Wrote code as

trigger numberofcontacts on contact(after insert, after update, after delete) {
    Map<Id, List<Contact>> AcctContactList = new Map<Id, List<Contact>>();
    Set<Id> AcctIds = new Set<Id>();   
    List<schema.Account> AcctList = new List<schema.Account>();
    List<schema.Contact> ConList = new List<schema.Contact>();
   
    if(trigger.isInsert || trigger.isUPdate) {
        for(Contact Con : trigger.New) {
            if(String.isNotBlank(Con.AccountId)){
                AcctIds.add(Con.AccountId); 
            }  
        } 
    }
   
    if(trigger.isDelete) {
        for(Contact Con : trigger.Old) {
            AcctIds.add(Con.AccountId);    
        } 
    }          
   
    if(AcctIds.size() > 0){
        ConList = [SELECT Id, AccountId FROM Contact WHERE AccountId IN : AcctIds];
       
        for(Contact Con : ConList) {
            if(!AcctContactList.containsKey(Con.AccountId)){
                AcctContactList.put(Con.AccountId, new List<Contact>());
            }
            AcctContactList.get(Con.AccountId).add(Con);     
        }                          
      
           
        AcctList = [SELECT noofContacts__c FROM Account WHERE Id IN : AcctIds];
        for(Account Acc : AcctList) {
            List<schema.Contact> ContList = new List<schema.Contact>();
            ContList = AcctContactList.get(Acc.Id);
            Acc.Number_of_Contacts__c = ContList.size();
        }   
       
      
        update AcctList;   
    }

}
 I am   getting an error as "Variable doesnot exist:id".

Kindly support and suggest.

Thanks
