  • Change this slide to match the local internet requirements.The bit.ly link points to the latest HTML draft of the new workbook. This is different than the official workbook on developer.force.com and there are schema differences, so attendees cannot mix and match.
  • Highlight that this is not just a day of talking to them, this is a dialogue and they should ask questions as they like – even ones that don’t pertain to the current “section”. Projects they’re working on, features they have heard about, etc.
  • THERE IS NOT A CURRENT ONLINE VERSION OF THE NEW WORKBOOK DRAFT

  • Let’s have an exercise in requirements gathering. Here is some of the core needs for our Warehouse application. What nouns here should we be looking at to model our data with?
  • Here is an overview of what our data model will look like. Recommended: Break into a demo of building data in the browser, either custom object wizard or schema builder depending on audience/workbooks
  • For when declarative logic is not enough, we provide Apex. Apex is a cloud-based programming language, very similar to Java – except that you can code, compile and deploy all right from your Salesforce instance. You’ll see how we can create robust programmatic functions right from your browser.

  • Apex
  • Introduction to Apex  Object-Oriented Language  Dot Notation Syntax  Case Insenstive  “First Class” Citizen on the Platform
  • Apex Anatomy Chapter 1: public with sharing class myControllerExtension implements Util { private final Account acct; public Contact newContact {get; set;} public myControllerExtension(ApexPages.StandardController stdController) { this.acct = (Account)stdController.getRecord(); } public PageReference associateNewContact(Id cid) { newContact = [SELECT Id, Account from Contact WHERE Id =: cid LIMIT 1]; newContact.Account = acct; update newContact; } } Class and Interface based Scoped Variables   Inline SOQL Inline DML  
  • Developer Console  Browser Based IDE  Create and Edit Classes  Create and Edit Triggers  Run Unit Tests  Review Debug Logs
  • Apex Triggers  Event Based Logic  Associated with Object Types  Before or After:  Insert  Update  Delete  Undelete
  • Controlling Flow trigger LineItemTrigger on Line_Item__c (before insert, before update) { //separate before and after if(Trigger.isBefore) { //separate events if(Trigger.isInsert) { System.debug(‘BEFORE INSERT’); DelegateClass.performLogic(Trigger.new);
  • Static Flags public with sharing class AccUpdatesControl { // This class is used to prevent multiple calls public static boolean calledOnce = false; public static boolean ProdUpdateTrigger = false; }
  • Chatter Triggers trigger AddRegexTrigger on Blacklisted_Word__c (before insert, before update) { for (Blacklisted_Word__c f : trigger.new) { if(f.Custom_Expression__c != NULL) { f.Word__c = ''; f.Match_Whole_Words_Only__c = false; f.RegexValue__c = f.Custom_Expression__c; } } }
  • Trigger Tutorial  Basic: Tutorial 2  Intermediate: Tutorial 4  Beyond Intermediate: http://bit.ly/ELEV-triggers http://bit.ly/elevate_adv_workbook
  • Unit Testing in Apex  Built in support for testing – Test Utility Class Annotation – Test Method Annotation – Test Data build up and tear down  Unit test coverage is required – Must have at least 75% of code covered  Why is it required?
  • Unit Testing • Declare Classes/Code as Test • isTest Annotation • testmethod keyword • Default data scope is test only
  • Testing Context // this is where the context of your test begins Test.StartTest(); //execute future calls, batch apex, scheduled apex // this is where the context ends Text.StopTest(); System.assertEquals(a,b); //now begin assertions
  • Testing Permissions //Set up user User u1 = [SELECT Id FROM User WHERE Alias='auser']; //Run As U1 System.RunAs(u1){ //do stuff only u1 can do }
  • Static Resource Data List<Invoice__c> invoices = Test.loadData(Invoice__c.sObjectType, 'InvoiceData'); update invoices;
  • Mock HTTP Endpoints @isTest global class MockHttp implements HttpCalloutMock { global HTTPResponse respond(HTTPRequest req) { // Create a fake response HttpResponse res = new HttpResponse(); res.setHeader('Content-Type', 'application/json'); res.setBody('{"foo":"bar"}'); res.setStatusCode(200); return res; } }
  • Mock HTTP Endpoints @isTest private class CalloutClassTest { static void testCallout() { Test.setMock(HttpCalloutMock.class, new MockHttp()); HttpResponse res = CalloutClass.getInfoFromExternalService(); // Verify response received contains fake values String actualValue = res.getBody(); String expectedValue = '{"foo":"bar"}'; System.assertEquals(actualValue, expectedValue); } }
  • Unit Testing Tutorial
  • Batch Apex
  • Apex Batch Processing  Governor Limits – Various limitations around resource usage  Asynchronous processing – Send your job to a queue and we promise to run it  Can be scheduled to run later – Kind of like a chron job
  • Batchable Interface global with sharing class WHUtil implements Database.Batchable<sObject> { global Database.QueryLocator start(Database.BatchableContext BC) { //Start on next context } global void execute(Database.BatchableContext BC, List<sObject> scope) { //Execute on current scope } global void finish(Database.BatchableContext BC) { //Finish and clean up context } }
  • Implementing Apex Batch Processing Apex Batch Processing Tutorial
  • Scheduled Apex
  • Schedulable Interface global with sharing class WarehouseUtil implements Schedulable { //General constructor global WarehouseUtil() {} //Scheduled execute global void execute(SchedulableContext ctx) { //Use static method for checking dated invoices WarehouseUtil.checkForDatedInvoices(); } }
  • Schedulable Interface System.schedule('testSchedule','0 0 13 * * ?', new WarehouseUtil()); Via Apex Via Web UI
  • Unit Testing Batch Apex Test.StartTest(); System.schedule(‘once','0 0 13 * * ?',new,WarehouseUtil()); ID batchprocessid = Database.executeBatch(new WarehouseUtil()); Test.StopTest();
  • Scheduling Apex Apex Scheduling Tutorial
  • Apex REST Services
  • Apex REST @RestResource(urlMapping='/CaseManagement/v1/*') global with sharing class CaseMgmtService { @HttpPost global static String attachPic() { RestRequest req = RestContext.request; RestResponse res = Restcontext.response; Id caseId = req.requestURI.substring(req.requestURI.lastIndexOf('/')+1); Blob picture = req.requestBody; Attachment a = new Attachment (ParentId = caseId, Body = picture, ContentType = 'image/
  • Apex REST Services REST Services with Apex Tutorial
  • Visualforce
  • Framework  Server-side compiled web pages – (Think PHP, JSP, etc.)  Easily create salesforce UI  Standard-compliant  Can Interact With Apex for Custom Logic
  • Visualforce Tags <apex:page docType=“html-5.0” /> <apex:input type=“email”/> <apex:pageBlockSection collapsible=“false” />
  • Hashed information block to track server side transports Viewstate
  • Apex Form  Required for standard salesforce post  Incurs Viewstate Overhead <apex:form> … </apex:form aspdoifuapknva894372h 4ofincao98vh0q938hfoq iwnbdco8q73h0o9fqubov ilbodfubqo3e8ufbw
  • Interacting with Apex  ActionFunction allows direct binding of variables  ActionFunction requires ViewState  JavaScript Remoting binds to static methods  JavaScript Remoting uses no ViewState  Transient, Private and Static reduce Viewstate
  • Apex Remote Action  Static  No View State  Invoked through JS API  Invokes JS Callback @remoteAction global static String myMethod(String inputParam){ ... }
  • Calling Apex Remote Action Visualforce.remoting.Manager.invokeAction(’ {!$RemoteAction.RemoteClass.methodName}' , param, function(result, event) { //...callback to handle result });
  • Event Object: Success Example { "statusCode":200, "type":"rpc", "ref":false, "action":"IncidentReport", "method":"createIncidentReport", "result":"a072000000pt1ZLAAY", "status":true }
  • Event Object: Failure Example { "statusCode":400, "type":"exception", "action":"IncidentReport", "method":"createIncidentReport", "message":"List has more than 1 row for assignment to SObject", "data": {"0": {"Merchandise__c":"a052000000GUgYgAAL","Type__c":"Accident","Desc ription__c":"This is an accident report"}}, "result":null, "status":false }
  • Interacting with the Publisher: Allow Submit  Make Submit Active  Payload true/false Sfdc.canvas.publisher.publish( { name: "publisher.setValidForSubmit", payload:true });
  • Interacting with the Publisher: Subscribe to Submit  Attach to Submit Event Sfdc.canvas.publisher.subscribe({ name: "publisher.post", onData:function(e) { // This subscribe fires when the user hits 'Submit' in the publisher postToFeed(); }});
  • Interacting with the Publisher: Close Publisher  Make the Submit Happen Sfdc.canvas.publisher.publish({name: "publisher.close", payload: { refresh:"true"}});
  • The Future! (Well, Spring „14)
  • Remote Objects  Standard CRUD/Q functionality without Apex  Similar to remoteTK or SObjectData  Visualforce components define data models <apex:jsSObjectBase shortcut="tickets"> <apex:jsSObjectModel name="Ticket__c" /> <apex:jsSObjectModel name="Contact" fields="Email" /> <script> var contact = new tickets.Contact(); contact.retrieve({ where: { Email: { like: query + '%' } } }, function(err, data) {
  • Canvas
  •  Only has to be accessible from the user‟s browser  Authentication via OAuth or Signed Response  JavaScript based SDK  Within Canvas, the App can make API calls as the current user  apex:CanvasApp allows embedding via Visualforce Any Language, Any Platform How Canvas Works
  • OAuth
  • Remote Application Salesforce Platform Sends App Credentials User logs in, Token sent to callback Confirms token Send access token Maintain session with refresh token OAuth2 Authentication Flow
  • Tools for teams and build masters Team Development
  • API to access customizations to the Force.com platform Metadata API
  • Access, create and edit Force.com application code Tooling API
