Get Ready for the Hands-on Challenge:-

Challenge

Practice simplifying object- and field-level security checks with new Spring ’19 in Apex code

Solution

Challenge step 1: Create the Secret Key custom text field on the Contact object as specified in the Get Ready for the Hands-on Challenge section.

For this step, I hope you already created the field as per trailhead steps. If not follow the below.

Login to salesforce lightning

Click on the Gear icon and click the setup

Click Object manager menu item and search for Contact object, In the contact object go to Fields and relationships sub tab

Click the New button and enter below details

Choose Field type as Text and click Next button 


In the next screen, fill the details as mentioned below and click Next button

Field Label: Secret Key, Field Name: Secret_Key and Length: 255

In the next screen, Uncheck the Visible box for the “Standard User” profile when defining field-level security and click Next 

Click save

Challenge step 2: Create a new Apex class named SecureApexRest.

Click the Gear icon at the top right corner of the salesforce application and click Developer console option

In the Developer console window, click File > New > Apex class > Enter the class name SecureApexRest, click Ok

Challenge step 3: Copy and paste the SecureApexRest code provided above. This code is already secured with conventional field- and object-level access checks.

You can copy and paste the below-mentioned code in your newly created class

@RestResource(urlMapping='/secureApexRest')

global with sharing class SecureApexRest {

    @HttpGet

    global static Contact doGet(){

        Id recordId = RestContext.request.params.get('id');

        Contact result;

        if (recordId == null){

            throw new FunctionalException('Id parameter is required');

        }

        try{

            List<Contact> results = [SELECT id, Name, Secret_Key__c FROM Contact WHERE Id = :recordId WITH SECURITY_ENFORCED];

            if (!results.isEmpty()) {

                result = results[0];

            }

        }catch(QueryException QE){

            throw new SecurityException('You don\'t have access to all contact fields required to use this API');

        }

        return result;

    }

    public class FunctionalException extends Exception{}

    public class SecurityException extends Exception{}

}

Save the apex class.

No changes required for further steps of the challenge. Check the solution by clicking on Check challenge button in the trailhead page. 

Quick Send Email Lightning Component

In This Post We are created a salesforce lightning component. By this component we can send Emails.

Quick Email Send Lightning Component looks like :

In Gmail.

EmailSendController.apxc:  (Apex Class)

public class EmailSendController {

 @AuraEnabled 

    public static void sendMailMethod(String mMail ,String mSubject ,String mbody){

    

     List<Messaging.SingleEmailMessage> mails =  new List<Messaging.SingleEmailMessage>();     

  

     // Step 1: Create a new Email

       Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();

    

    // Step 2: Set list of people who should get the email

       List<String> sendTo = new List<String>();

       sendTo.add(mMail);

       mail.setToAddresses(sendTo);

    

    // Step 3: Set who the email is sent from

       mail.setReplyTo('noreply@gmail.com'); // change it with your mail address.

       mail.setSenderDisplayName('salesforce User'); 

    

    // Step 4. Set email contents - you can use variables!

      mail.setSubject(mSubject);

      mail.setHtmlBody(mbody);

    

    // Step 5. Add your email to the master list

      mails.add(mail);

    

  // Step 6: Send all emails in the master list

     Messaging.sendEmail(mails);

   }   

}
