Access Apex Class Properties in Lightning Component

Apex Class:

public class SampleAuraController {
    
    //Properties
    @AuraEnabled public String FirstName {get;set;}
    @AuraEnabled public String LastName {get;set;}
    
    @AuraEnabled
    public static SampleAuraController getData() {
        SampleAuraController obj = new SampleAuraController();
        obj.FirstName = 'Biswajeet';
        obj.LastName = 'Samal';
        return obj;
    }
}

Lightning Component:

<!--Sample.cmp--> 
<aura:component controller="SampleAuraController" implements="flexipage:availableForAllPageTypes,force:appHostable">
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>
    <aura:attribute name="obj" type="SampleAuraController"/>
    <!--Component Start-->
    <div class="slds-m-around_xx-large">
        <strong>First Name : {!v.obj.FirstName}</strong>
        <br/>
        <strong>Last Name : {!v.obj.LastName}</strong>
    </div>
    <!--Component End-->
</aura:component>

Lightning Component JS Controller:

({
    doInit : function(component, event, helper) {
        var action = component.get('c.getData');
        action.setCallback(this,function(response){
            var state = response.getState();
            if (state === "SUCCESS") {
                var result = response.getReturnValue();
                component.set('v.obj', result);
            }
        });
        $A.enqueueAction(action);
    }
})

Output:

Salesforce Test Class Data For ContentDocument

Sample Code:

//Create Document
ContentVersion cv = new ContentVersion();
cv.Title = 'Test Document';
cv.PathOnClient = 'TestDocument.pdf';
cv.VersionData = Blob.valueOf('Test Content');
cv.IsMajorVersion = true;
Insert cv;

//Get Content Version
List<ContentVersion> cvList = [SELECT Id, Title, ContentDocumentId FROM ContentVersion WHERE Id = :cv.Id];
System.assertEquals(cvList.size(), 1);

//Get Content Documents
List<ContentDocument> cdList = [SELECT Id, Title, LatestPublishedVersionId FROM ContentDocument];
System.assertEquals(cdList.size(), 1);

Salesforce Test Class Data For ContentDocumentLink

Sample Code:

//Create Document Parent Record
Account acc = new Account(Name='Test Account');
Insert acc;

//Create Document
ContentVersion cv = new ContentVersion();
cv.Title = 'Test Document';
cv.PathOnClient = 'TestDocument.pdf';
cv.VersionData = Blob.valueOf('Test Content');
cv.IsMajorVersion = true;
Insert cv;

//Get Content Documents
Id conDocId = [SELECT ContentDocumentId FROM ContentVersion WHERE Id =:cv.Id].ContentDocumentId;

//Create ContentDocumentLink 
ContentDocumentLink cdl = New ContentDocumentLink();
cdl.LinkedEntityId = acc.Id;
cdl.ContentDocumentId = conDocId;
cdl.shareType = 'V';
Insert cdl;

Get Data From Visualforce Controller Extension Without SOQL Query

When a Visualforce page is loaded, the fields accessible to the page are based on the fields referenced in the Visualforce markup. But we can use StandardController.addFields(List fieldNames) method, which adds a reference to each field specified in fieldNames so that the controller can explicitly access those fields as well.

public with sharing class AccountControllerExt {
    public Account acc {get; set;}
    
    public AccountControllerExt(ApexPages.StandardController controller) {
        List<String> accFieldList = new List<String>();
        //Passing a list of field names to the standard controller
        controller.addFields(new List<String>{'Id', 'Name', 'AccountNumber', 'Website', 'Phone','Type', 'Industry'});
        //Standard controller to retrieve the field data of the record
        acc = (Account)controller.getRecord();
    }
}

Padding String in Salesforce Apex

Left Pad:

leftPad(length): Returns the current String padded with spaces on the left and of the specified length. If length is less than or equal to the current String size, the entire String is returned without space padding.

String name = 'biswa';
String lpName = name.leftPad(8);
System.debug('LeftPad-' + lpName);
System.assertEquals('   biswa', lpName);

leftPad(length, padStr): Returns the current String padded with String padStr on the left and of the specified length. padStr to pad with; if null or empty treated as single blank.

Integer num = 555;
String lpString = String.valueOf(num).leftPad(5, '0');
System.debug('LeftPad-' + lpString);
System.assertEquals('00555', lpString);

Right Pad:

rightPad(length): Returns the current String padded with spaces on the right and of the specified length. If length is less than or equal to the current String size, the entire String is returned without space padding.

String name = 'biswa';
String rpName = name.rightPad(8);
System.debug('RightPad-' + rpName);
System.assertEquals('biswa   ', rpName);

rightPad(length, padStr): Returns the current String padded with String padStr on the right and of the specified length. padStr to pad with; if null or empty treated as single blank.

Integer num = 555;
String rpString = String.valueOf(num).rightPad(5, '0');
System.debug('RightPad-' + rpString);
System.assertEquals('55500', rpString);
