public PageReference associateNewContact(Id cid) { newContact = [SELECT Id, Account from Contact WHERE Id =: cid LIMIT 1]; newContact.Account = acct; update newContact; }}

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; } }}

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 beginsTest.StartTest();

//execute future calls, batch apex, scheduled apex

// this is where the context endsText.StopTest(); System.assertEquals(a,b); //now begin assertions

Testing Permissions

//Set up userUser u1 = [SELECT Id FROM User WHERE Alias='auser']; //Run As U1System.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

@isTestglobal 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

@isTestprivate 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 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/

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

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

RemoteApplication

SalesforcePlatform

Sends App Credentials

User logs in,Token sent to callback

Confirms token

Send access token

Maintain session withrefresh 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
