My use case behind this blog post is to expose Salesforce Attachment (Image/Pdf/Video) as a public accessible CURL, without having to authenticate to Salesforce. And we are going to use REST Web-services and Public Sites to do this! Step 1: Create an Apex REST class with below code snippet. /* * Purpose : Apex rest webservice to return attachment body for a given id * * Developer: SFDC_Dev * */ @RestResource (urlMapping = '/Document_V1/*' ) global class DocumentV1 { @HttpGet global static void docBody() { RestRequest request = RestContext . request; RestResponse res = RestContext . response; try { // Retrieve attachment id from the request url String docId = request . requestURI . substring(request . requestURI . lastIndexOf( '/' ) + 1 ); // Query attachment sObject to get the specific attachment using attachment id ...

Recently at one of the local Hackathon I came across some scenario based Apex programming questions and I thought I would go ahead and blog on them. Below are three scenarios on which we are going to write some Apex code! Scenario 1: Create a Method which accepts List of String and returns a Map with count on how many times a specific value is repeated in a given List. Example:- List should result in "{A=3, B=2, C=1}" Approached Solution: Below is my Apex class with a method to accept List and returns a Map. /* * Purpose: Hackathon Programming Scenarios * * Developer: HackathonDev */ public class HackathoScenarios { // Method to return a map with string occurence count that was passed in a list public static Map < String, Integer > scenario1(List < String > lstStrng) { Map < String, Integer > mapVals = new Map < String, Integer > (); for (String s: lstStrng)...

As always with every release Salesforce introduces bunch of new base components and this time they have "Lightning: recordForm" which suppresses using "lightning:recordEditForm and lightning:recordViewForm" separately to handle record view and edit. Lets go ahead and put some sample code to create a Lightning Component using lightning recordForm! RecordFormComp.cmp: <aura:component implements= "force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasSObjectName,force:hasRecordId,force:lightningQuickAction" access= "global" > <aura:attribute name= "fieldsList" type = "String[]" default= "['Id', 'Name', 'BillingAddress', 'AnnualRevenue']" /> <div> <center> <h1><b>Lightning Record Form<br/> Object_Name: { ! v.sObjectName} - Record_Id: { ! v.recordId} ...

Business Scenario: To dynamically Show or Hide content in Lightning Components. Using "Document.getElementById" Below are Component and Controller code to show or hide content by using Document.getElementById HideShow.cmp <aura:component implements= "force:appHostable,flexipage:availableForAllPageTypes,flexipage:availableForRecordHome,force:hasRecordId,force:lightningQuickAction" access= "global" > < ! --Set component attribute--> <aura:attribute name= "valSet" type = "Set" /> <center> < ! --Button to display Set values--> <lightning:button onclick= "{!c.getSetValues}" label= "Set Values" /> </center> < ! --Construct HTML Table using SLDS--> <table class= "slds-table slds-table--bordered slds-table--striped slds-table--cell-buffer slds-table--fixed-layout" > <thead> <tr c...

Collections are building blocks for any object oriented programming language. In Apex we use LIST, SET, MAP collection types in order to work with records! Here in this blog, we are going look at some basic code on using Collection Types in context with Lightning Components..... First we create an Apex Controller with two methods to return List and Map respectively. We will use these methods to access from our Lighting Component and display them on the Home Page. public class LightningCollectionTypes { @AuraEnabled public static List < Account > lghtList() { List < Account > lstAccnts = [SELECT Id, Name FROM Account LIMIT 22 ]; return lstAccnts; } @AuraEnabled public static Map < Id, Account > lghtMap() { Map < ID, Account > m = new Map < ID, Account > ([SELECT Id, Name FROM Account LIMIT 22 ]); return m; } } LIST Below are component and...

With new Salesforce UI API we can get the orgs data and metadata in a single response returned form an Api call. Even Salesforce uses the same UI API to build their Lightning Experience and Salesforce for Android, iOS, and mobile web. While making calls and getting the data, salesforce does take care of checking the field-level security settings, sharing setting, and perms. We don't have to worry about making the SOQL queries to get record data, getting object metadata and themes info, getting layout info, all this heavy lifting work will be taken care by Salesforce. Best part is that every response is returned in a formatted JSON! UI API Endpoints are divided into 3 levels namely 1. Records Endpoint 2. Actions Endpoint 3. Favorites Endpoint For Authentication, User Interface API uses OAuth 2.0 just like all other Salesforce REST APIs does Reference Links: 1. User Interface API Developer Guide 2.
