How To Reset Security Token In Salesforce

How to reset security token:

Before we know how to reset security token ,let us see what is it means.

Security Token In Salesforce :

Security token is alphanumeric key that is used along with password to access salesforce through API .The reason to use the token is to make the salesforce more secured in case of API connections.

Example :If you have client data resides on oracle server and it integrates with salesforce via informatica tool to exchange data between oracle server and salesforce .Salesforce contains separate integration user ,which is responsible for data exchange between client server and salesforce .

Now informatica should use integration user credentials to establish the connection with salesforce. During authentication with salesforce, Informatica uses integration username and password along with security token to establish the connection.

Please follow the below steps to reset the security token :

1.Click on your name and navigate to My Settings as shown in Picture 1:

Picture 1:

2.Navigate to Personal tab in the left side and click on Reset Security Token option as shown in the picture 2.

picture 2:




















3.Now Finally click on Reset Security Token button to reset your security token. 

Picture 3:

4.After following the above steps you will receive new security token to your email .

Picture 4:

Reset security token for the profiles which enabled with login IP ranges :

If the profile is enabled with login Ip ranges ,then reset your security token option does not appear in My Settings .In this case you might have to disable the IP ranges till token reset and again you can add back the ip ranges .

We hope you are cleared with the process.

If you still require further clarifications,Please let us know in the comments .

Apex Trigger Examples || Salesforce Apex Triggers

Basic Apex Trigger Examples:

1.DemoTtrigger1

DemoTtrigger1 Populates Description field with the user first name who creates or updates the record by using userInfo standard keyword . And also does not allow user to delete the record .

trigger DemoTtrigger1 on Author__c (before insert,before update,before delete) {
    If(trigger.isInsert){
        for(Author__c Author: Trigger.new){
            //Populates Description with the user first name who creates the record
            Author.Description__c = 'Author Created by '+ userInfo.getFirstName(); 
        }
    } else
        If(trigger.isUpdate){
            for(Author__c Author: Trigger.new){
          //Updates Description with the user first name who updates the record
                Author.Description__c = 'Author Last updated by '+ userInfo.getFirstName();   
            }
        }
    if(Trigger.isDelete&&Trigger.isbefore){ 
        for(Author__c Rec:trigger.old) 
        {
          //User gets the below error when user tried to delete the record
            Rec.adderror('You Cannot Delete the Author Record');
        }
    }
}


2.DemoTrigger2

Whenever new account record creates"Account_Rep__c"  updates with the account owner name.
  
trigger DemoTrigger2 on Account (before insert) {
    Set<Id>setAccOwner=new Set<Id>(); 
    for(Account Acc: trigger.new) 
    { 
        setAccOwner.add(Acc.OwnerId);     
    }
    map<id,user>userMap=new map<id,user>();
    for(user u:[select id,Name from user where id IN:setAccOwner]){
        userMap.put(u.id,u);
    }
    for(Account Acc: Trigger.new)
       
    { 
        User usr=UserMap.get(Acc.OwnerId); 
        system.debug('usr');
        Acc.Account_Rep__c=usr.Name; 
    }
}

Note :Most of the examples here made use of  Map/List .If you are not sure about the Map/List concepts ,Please make use of below post which clearly explains about collections in salesforce .
https://salessforcehacks.blogspot.com/2020/01/collections-in-salesforce-list-set-map.html

  3.DemoTrigger3

DemoTrigger3 prevents user to delete contact which is associated with the any account. When user tries to delete associated contact ,User will be presented with the error "Contact associated with account cannot be deleted"

trigger DemoTrigger3 on Contact (before delete) {
    //Contact with associated account cannot be deleted
   if(Trigger.isDelete&&Trigger.isbefore){
    for(contact con:Trigger.old){
        if(con.accountId!=null){
            con.addError('Contact associated with account cannot be deleted');
        } 
       
    }}

4.DemoTrigger4

 Creates opportunity record if the account doesn't contain at least one opportunity.

trigger DemoTrigger4 on Account(after insert, after update) {
    List<Opportunity> oppList = new List<Opportunity>();
   
    // Get the related opportunities for the accounts in this trigger
    Map<Id,Account> acctsWithOpps = new Map<Id,Account>(
        [SELECT Id,Name,(SELECT Id,Name FROM Opportunities) FROM Account WHERE Id IN :Trigger.New]);
    System.debug('acctsWithOpps  ::'+acctsWithOpps);
   
    // Add an opportunity for each account if it doesn't already have one.
    // Iterate through each account.
    for(Account a : Trigger.New) {
        System.debug('acctsWithOpps.get(a.Id).Opportunities.size()=' + acctsWithOpps.get(a.Id).Opportunities.size());
        // Check if the account already has a related opportunity.
        if (acctsWithOpps.get(a.Id).Opportunities.size() == 0) {
            // If it doesn't, add a default opportunity
            oppList.add(new Opportunity(Name=a.Name + ' Opportunity',
                                       StageName='Prospecting',
                                       CloseDate=System.today().addMonths(1),
                                       AccountId=a.Id));
        }         
    }
    if (oppList.size() > 0) {
        insert oppList;
    }
}

5.DemoTrigger5

 DemoTrigger5 send email notification after new student record created into the system.               Trigger makes use of handler class to send an email notification. Trigger collects newly created     student records and send them to the handler class to process further for the email   notification.

trigger DemoTrigger5 on student__c (After insert) {
   if(Trigger.isinsert&&Trigger.isafter){
       StudentEmailNotification.sendMail(Trigger.new); 
   }

}

class :

public class StudentEmailNotification {
    // Public method
    public static void sendMail(List<student__c> stuList) {
        // Create an email message object
        system.debug('stuList in sendmail method :'+stuList);
        for(student__c st :stuList){
            Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
            String address=st.Email__c;
            String[] toAddresses = new String[] {address};
            String ccAddresses=st.Class_Owner_Email__c ;
            system.debug('ccAddresses :'+ccAddresses);
            String[] setCcAddresses=new String[] {ccAddresses};
            mail.setToAddresses(toAddresses);
            mail.setCcAddresses(setCcAddresses);
            mail.setSubject('Student Registration Notification');
            mail.setPlainTextBody
                ('The Student' + st.Name + ' Registration is Completed with the below details :'+'\n\n' +
                 'Student Name : ' + st.Name + '\n\n'+
                 'Request Email : ' +st.Email__c + '\n\n' +
                 'Class: ' +st.Class__c+ '\n\n' +
                 'Please reach out to System Administrator if you require any further information');
            Messaging.SendEmailResult[] results = Messaging.sendEmail(
                new Messaging.SingleEmailMessage[] { mail });
        }
    }
}

6.DemoTrigger6 

 Updates "Associated_Contacts__c" with the number of contacts associated with the account .   Whenever new contact creates/removed from the account ,The respective count would be   increased/Decreased accordingly. 

trigger DemoTrigger6 on Contact (before delete,before insert,after insert,after delete,after update) {
    //Update count of the contact to the 'Associated Contacts' field in the account
    set<id> accid=new set<id>();
    list<contact> contactlist =new list<contact>();
    list<contact> listcon=new list<contact>();
    list<account> listAcc=new list<account>();
    list<account> acclist=new list<account>();
    map<id,integer> mapCount=new map<id,integer>();
    
    if(trigger.isinsert){
        
        for(contact con:trigger.new){
            
            accid.add(con.accountid);
            
        }
        
    }
    
    if(trigger.isdelete){
        
        for(contact con:trigger.old){
            
            accid.add(con.accountid);
            
        }
        
    }
    
    acclist=[select id,name,Overall_Contacts_Status__c from account where id in:accid];
    
    contactlist = [select id,Status__c,name,accountid from contact where accountid in:accid];
    
    for(account acc:acclist){
        
        listcon.clear();
        
        for(contact c:contactlist){
            
            if(c.accountid==acc.id){
                
                listcon.add(c);
            }
        }
        mapCount.put(acc.id,listcon.size());
    }
    if(acclist.size()>0){
        for(Account a:acclist){
            if(mapCount.get(a.id)==null)
                a.Associated_Contacts__c=0;
            else
                a.Associated_Contacts__c=mapCount.get(a.id);
            listAcc.add(a);
        }
    }
    if(listAcc.size()>0)
        update listAcc;    

}  

 //you can also reduce the code with account inner query like below

trigger DemoTrigger6 on Contact (before delete,before insert,after insert,after delete,after update) {

 set<id> accountIds=new set<id>();

    List<account> accList=new List<account>();

    map<id,integer> noOfContacts=new map<id,integer>();

    List<account> updateaccList=new List<account>();

    if(Trigger.isinsert||Trigger.isUpdate&&Trigger.isafter){

        for(contact con:Trigger.new){

            if(Trigger.isinsert){

                accountIds.add(con.accountId);

            }else if(Trigger.isUpdate&&trigger.oldmap.get(con.id).accountId!=null&&con.accountId==null){

                accountIds.add(trigger.oldmap.get(con.id).accountId);

            }

        }

    }

    if(Trigger.isDelete&&Trigger.isafter){

        for(contact con:Trigger.old){

            accountIds.add(con.accountId);

        }

        

    }

    system.debug('accountIDs:'+accountIds);

    accList=[select id,(select id,accountId from contacts) from account where id IN:accountIds];

    

    for(account acc:accList){

        if(acc.contacts.size()>0){

            acc.Associated_Contacts__c=acc.contacts.size();

        }else{

            acc.Associated_Contacts__c=0; 

        }

        updateaccList.add(acc);

    }

    system.debug('updateaccList:'+updateaccList);

    update updateaccList;

}

7.DemoTrigger7

DemoTrigger7 helps to avoid recursive trigger by using the handler.

trigger DemoTrigger7 on Account (after insert) {
     if(RecursionExampleHandler.isFirstTime){
          RecursionExampleHandler.isFirstTime=false;
    for(account a:Trigger.new){
        account acc=new account();
     acc.Name='Recursive Test';
        insert acc;
    }
     }
}

class :

public class RecursionExampleHandler {
public static Boolean isFirstTime=True;
}

https://salessforcehacks.blogspot.com/2019/12/salesforce-recursive-triggers-fully.html 

8.Apex Managed Sharing :

Until now Most of us know the methods of sharing the records across organization by using sharing rules  and OWD ,This example helps us to share records in programmatic way(Apex Trigger/Apex Class) for the complex business requirements .

Scenario Based Example:

Prerequisite:

Objects Used in the discussion:

1.Project--Object contains all the business task details which require to be completed .

2.Project Member--Are the members who work on the project which has assigned to them.
   Project Member is junction object which is master-Detail with Project and Contact

3.Contact--Sales force Contact Object
   Assume all the contacts Owner is assigned with their own User ID .
Eg .We have user Kris who is also Owner for associated contact named Kris .

Use Case :

1.Whenever status of the project changed from 'New' to 'Assigned' The respective project record access should be shared with all the Project Members .

2.Once the Project Members completed their assigned task and Status of the Project changes to 'Completed' then Access should be Revoked/Removed from the Project Team Members .

Solution: 

We require to create Apex Trigger on Project object and create the share object records and delete the access after Project completed

The below Trigger collects all the project records for which status changed to 'Assigned' Or changed to 'Completed' and send them to Apex class to create and Revoke the access respectively  by using apex sharing .

Apex Trigger :

trigger ProjectShare on Project__c (after update) {

    List<Project__c > projectShareList=new List<Project__c >();

    List<Project__c > revokeShareList=new List<Project__c >();

    //Share the access

    if(Trigger.isafter&&Trigger.isUpdate){
   
        for(Project__c Pro:Trigger.new){
       
            if(Pro.Status__c=='Assigned'&&trigger.oldmap.get(Pro.id).Status__c!='Assigned'){
           
                projectShareList.add(Pro);
           
                system.debug('Share the access'+Pro.id);
           
            }
       
        }
     
        if(projectShareList!=null){
         
            ProjectShareclass.provideAccess(projectShareList);
           
        }
   


        //Revoke the access
   
        for(Project__c Pro:Trigger.new){
       
            if(Pro.Status__c!='Assigned'&&trigger.oldmap.get(Pro.id).Status__c=='Assigned'){
           
                system.debug('Revoke the access'+Pro.id);
           
                revokeShareList.add(std);
           
            }
       
        }
        if(revokeShareList!=null){
       
            ProjectShareclass.revokeAccess(revokeshareList);
       
        }
    }
}

Apex Class :

    public static void  provideAccess(List<Project__c > pros){
   
        List<Project_member__c> tmList=new List<Project_member__c>();
   
        map<id,Project_member__c> tmmap=new map<id,Project_member__c>();
   
        List<Project__Share> shareList=new List<Project__Share>();
   
       tmList=[select id,project__c,MasterDetailWithcontact__r.owner.id from Project_member__c where Project__c IN:pros];
        for(Project_member__c s:tmList){
       
            tmmap.put(s.Project__c,s);
       
        }
   
        for(Project__c rec:Pros){
       
            Project__Share share=new Project__Share();
       
            share.ParentId = rec.id;
       
            share.AccessLevel = 'Edit';
       
            share.RowCause = Schema.Project__Share.RowCause.Manual;
       
            share.UserOrGroupId = tmmap.get(rec.id).MasterDetailWithcontact__r.owner.id;
       
            shareList.add(share);
       
        }
   
        insert shareList;
   
    }

    public static void  revokeAccess(List<Project__c> pros){
   
        List<Project__Share> shareList=new List<Project__Share>();
   
        shareList=[select id from Project__Share where parentId IN:pros AND RowCause = 'Manual'];
   
        delete shareList;
    }
}

Result :

Once the project record is created into the database ,By default only owner of the record will have access to record as shown in Screenshot 2 :

Screenshot 2:

Once the above project record updated to the 'Assigned' status  ,Access of the project record will be shared to project team member . Please find the ScreenShot 3.

First Share record with all access Level belongs to the default record owner access . And Second Share record with Edit access and RowCause 'Manual' belongs to Share record created by above Apex trigger and Apex class.

ScreenShot 3 :




If you update the Status to 'Completed' again the 'Edit' access would be revoked/Deleted to all the Project Members associated to Project object.

Lightning Data Service Basics for Aura Components challenge passed/Completed ||Trailhead Challenge||Lightning Data Service||LDS

Lightning Data Service :

Lightning data service is similar to Standard controller in Visualforce page .We can make the server calls without using server side controller.
Lightning Data Service Basics for Aura Components trailhead module provides clear information about LDS with hands on examples .
If you find any difficulty in passing the challenge ,Please compare your code with the below written code

1.Manipulate Records with force:recordData

Use force:recordData to create two Aura components that display and edit the details of an account

Create Aura components to manage accounts. Use force:recordData to create a component that displays the details of a standard account record, and another component that allows for quick edits to that record.

Solution :Create accDisplay component with the particulars mentioned in the trailhead challenge .If you face any issues please compare your code with the below code and modify accordingly.

2.Handle Record Changes and Errors

Use force:recordData to create a component that shows an error message if it is loaded with invalid data Build on the components you created in the previous unit challenge by adding notification handling to your components. If the edits in your editable component create an error, make sure the display component shows an error message.

accEdit.cmp:
<aura:component implements="flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,force:lightningQuickAction" access="global" >
    <aura:attribute name="record" type="object"/>
    <aura:attribute name="accountRecord" type="object"/>
    <aura:attribute name="recordSaveError" type="String"/>
