Salesforce Custom Object to Save Logs

As a Salesforce developer sometimes we face different scenarios, where we need to track production error logs or failed records. To save custom logs, here I have created an object Log__c and a helper class LogHandler, which will help to save custom logs for future references.

Object (Log__c) Fields:

Field Label Field API Name Field Type
Class Class__c Text(255)
Method Method__c Text(255)
Description Description__c Long Text Area(32768)
Line Number Line_Number__c Number(8, 0)
HTTP Response HTTP_Response__c Long Text Area(32768)
HTTP Status Code HTTP_Status_code__c Number(6, 0)
Object Object__c Text(255)
Record Id Record_Id__c Text(255)
Type Type__c Picklist(Success, Error, Information)

Apex Class:

public class LogHandler
{
    //Save information log
    public static void logInformation(String className, String methodName, String description){
        Log__c log = new Log__c();
        log.Class__c = className;
        log.Method__c = methodName;
        log.Description__c = description;
        log.Type__c = 'Information';
        Insert log;
    }
    
    //Save success log
    public static void logSuccessData(String className, String methodName, String description){
        Log__c log = new Log__c();
        log.Class__c = className;
        log.Method__c = methodName;
        log.Description__c = description;
        log.Type__c = 'Success';
        Insert log;
    }
    
    //Save exception log
    public static void logException(String className, String methodName, String description, Integer lineNumber){
        Log__c log = new Log__c();
        log.Class__c = className;
        log.Method__c = methodName;
        log.Description__c = description;
        log.Type__c = 'Error';
        log.Line_Number__c = lineNumber;
        Insert log;
    }
    
    //Save HTTP response log
    public static void logHTTPResponse(String className, String methodName, String description, HttpResponse response){
        Log__c log = new Log__c();
        log.Class__c = className;
        log.Method__c = methodName;
        log.Description__c = description;
        log.Type__c = 'Information';
        if(response != null){
            log.HTTP_Response__c = response.getBody();
            log.HTTP_Status_code__c = response.getStatusCode();			
        }
        Insert log;
    }
    
    //Save result log
    public static void logSaveResult(String className, String methodName, List<Database.SaveResult> saveResultList){
        List<Log__c> logList = new List<Log__c>();
        for (Database.SaveResult sr: saveResultList) {        
            if (sr.isSuccess()) {                    
                Log__c log = new Log__c();
                log.Class__c = className;
                log.Method__c = methodName;
                log.Type__c = 'Success';
                if(sr.getId() != null){
                    log.Object__c = sr.getId().getSObjectType().getDescribe().getName();
                    log.Record_Id__c = sr.getId();
                }
                logList.add(log);                    
            }else{
                Log__c log = new Log__c();
                log.Class__c = className;
                log.Method__c = methodName;
                log.Type__c = 'Error';
                log.Description__c = String.valueOf(sr.getErrors()[0].getMessage());
                logList.add(log);  
            }
        }
        if(!logList.isEmpty()){
            Insert logList;
        }	
    }
    
    //Upsert result log
    public static void logUpsertResult(String className, String methodName, List<Database.UpsertResult> upsertResultList){
        List<Log__c> logList = new List<Log__c>();
        for (Database.UpsertResult ur: upsertResultList) {        
            if (ur.isSuccess()) {                    
                Log__c log = new Log__c();

                    log.Record_Id__c = ur.getId();
                }
                logList.add(log);                    
            }else{

Lightning Formatted URL

A lightning:formattedUrl component displays a read-only representation of a URL as a hyperlink with an href attribute. The link can be a relative or absolute URL.

Example:

<aura:component>  
    <lightning:formattedUrl value="https://www.google.com" tooltip="Google" label="Click to Open" target="_blank" />
</aura:component>

Output:

Lightning Vertical Navigation

A lightning:verticalNavigation component represents a list of links that’s only one level deep, with support for overflow sections that collapse and expand. Here is an example of Lightning Vertical Navigation.

Apex Class:

public with sharing class AuraSampleController{
    
    @AuraEnabled
    public static List<Account> getAccounts(){
        List<Account> accList = new List<Account>();
        accList = [SELECT Id, Name, AccountNumber, Industry From Account LIMIT 10];
        return accList;
    }
}

Lightning Component:

<aura:component controller="AuraSampleController" Implements="flexipage:availableForRecordHome,force:hasRecordId">
    
    <!--Declare Attributes-->
    <aura:attribute name="selectedaccId" type="Id" />
    <aura:attribute name="accList" type="Account[]" />
    
    <!--Declare Handler-->
    <aura:handler name="init" value="{!this}" action="{!c.doInit}"/>  
    
    <!--Component Start-->
    <div class="slds-m-around--xx-large">
        <lightning:layout>
            <lightning:layoutItem>
                <lightning:verticalNavigation onbeforeselect="{!c.handleBeforeSelect}"
                                              selectedItem="{!v.selectedaccId}"
                                              onselect="{!c.handleOnSelect}">
                    <lightning:verticalNavigationSection label="Select Account">
                        <aura:iteration items="{!v.accList}" var="acc" indexVar="index">
                            <lightning:verticalNavigationItem label="{!acc.Name}" name="{!acc.Id}" />
                        </aura:iteration>
                    </lightning:verticalNavigationSection>
                </lightning:verticalNavigation>
            </lightning:layoutItem>
            <lightning:layoutItem padding="around-medium">
                <p>You have selected : {!v.selectedaccId}</p>
            </lightning:layoutItem>
        </lightning:layout>
    </div>
    <!--Component End-->
</aura:component>

Lightning JS Controller:

({
    doInit: function(component, event, helper) {
        helper.getAccountList(component, event);
    },
    
    handleBeforeSelect: function(component, event) {
        //Write your logic before select of any item
    },
    
    handleOnSelect: function(component, event) {
        //Write your logic on select of any item
    }
})

Lightning JS Helper:

({
    getAccountList: function(component, event) {
        var action = component.get("c.getAccounts");
        action.setCallback(this, function(response) {
            var state = response.getState();
            if (state === "SUCCESS") {
                var result = response.getReturnValue();
                component.set("v.accList", result);
            }
        });
        $A.enqueueAction(action);
    },
})

Output:

Invoke Visualforce Page Javascript Method From Lightning Component

Lightning Component:

    //Function to call from Lightning Component
    function getMessage(welcomeMsg){
        alert(welcomeMsg);
    }

Invoke Lightning Component Methods From Visualforce Page

We can use aura:method to invoke lightning controller methods from visualforce page. The below example is to call Lightning Component methods from visualforce page.

Lightning Component:

<!--SampleComponent.cmp--> 
<aura:component implements="flexipage:availableForAllPageTypes,force:appHostable" access="global">
    <!--Aura Method-->
    <aura:method name="welcomeMsgMethod" action="{!c.doAction}" access="global">

        <aura:attribute name="name" type="String"/> 
    </aura:method>
    
    <!--Declare Attributes-->
    <aura:attribute name="msg" type="String"/>
    
    <!--Component Start--> 
    <div class="slds-m-around_xx-large">
        <!--Print Welcome Message--> 
        {!v.msg}
    </div>
    <!--Component End-->
</aura:component>

Lightning Controller:

({
    doAction : function(component, event, helper) {
        //Get Parameters
        var params = event.getParam('arguments');
        if (params) {
            //Get Welcome message parameter
            var msg = params.message.message;
            var developerGroup = params.message.developerGroup;
            //Get name parameter
            var name = params.name;
            //Set welcome message and name
            component.set("v.msg", name + ' ' + msg + ' ' + developerGroup);
        }
    }
})

Lightning App:

<!--SampleApp.app--> 
<aura:application extends="ltng:outApp" access="global">

                                   });
    });
    
    //Method to call Lightning Component Method
    var getWelcomeMessage = function(){
        component.welcomeMsgMethod({message : "Welcome to Salesforce Ohana", developerGroup: "Bengaluru"}, "Biswajeet Samal");
    }
    </script>
