Declarative Approach Programmatic Approach

Declarative before Programmatic
Use declarative features when possible:
• Quicker to build
• Easier to maintain and debug
• Possible addition of new features
• Do not count against governor limits
For example:
• Will a workflow suffice instead of a trigger?
• Will a custom layout work instead of Visualforce?

Apex
Cloud-based programming language on Salesforce1

Introduction to Apex
• Object-Oriented Language
• Dot Notation Syntax
• Cloud based compiling, debugging and unit
testing

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;
}
}
Apex Anatomy
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

Unit Testing
Code which asserts that existing logic is operating correctly

• Code to test code
• Tests can mirror user
expectations
• System Asserts increase
predictability
• Line Coverage increase
predictability
Unit Testing

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?

Basic Unit Test Structure
@isTest
public class TestClase{
@isTest static void testCase(){
//setup test data
List<Contact> contacts = ContactFactory.createTestContacts();
//process / perform logic
EvaluateContacts.process(contacts);
//assert outcome
System.assertEquals(EvaluateContacts.processed.size(),contacts.size());
}
}

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
}

ProTip: Load Static Resource Data from CSV
List<Invoice__c> invoices = Test.loadData(Invoice__c.sObjectType, 'InvoiceData');
update invoices;

Testing Context and Asynchronous Behavior
// this is where the context of your test begins
Test.StartTest();
//execute future calls, batch apex, scheduled apex
UtilityRESTClass.performCallout();
// this is where the context ends
Test.StopTest();
System.assertEquals(a,b); //now begin assertions

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);

Scheduled Apex
Interface for scheduling Apex jobs

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();
}
}

System.schedule('testSchedule','0 0 13 * * ?',
new WarehouseUtil());Via Apex
Via Web UI
Schedulable Interface

Batch Apex
Apex interface for processing large datasets asynchronously

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 cron 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 }
}

ProTip: Unit Testing Asynchronous Apex
//setup test data
Test.StartTest();
System.schedule('testSchedule','0 0 13 * * ?',new WarehouseUtil());
ID batchprocessid = Database.executeBatch(new WarehouseUtil());
Test.StopTest();
//assert outcomes

Apex Integration
Using Apex with third party systems

Apex HTTP
public FlickrList getFlickrData(string tag) {
HttpRequest req = new HttpRequest();
req.setMethod('GET');
req.setEndpoint('http://api.flickr.com/services/feeds/photos_public.gne?
nojsoncallback=1&format=json&tags='+tag);
HTTP http = new HTTP();
HTTPResponse res = http.send(req);
return
(FlickrList)JSON.deserialize(res.getBody().replace(''',''),FlickrList.class
);
}

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/

ProTip: Unit Tests: Mock HTTP Endpoints
@isTest
global class MyMockHttp 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;
}
}

Unit Tests: Mock HTTP Endpoints
@isTest
private class CalloutClassTest {
static void testCallout() {
Test.setMock(HttpCalloutMock.class, new MyMockHttp());
HttpResponse res = CalloutClass.getInfoFromExternalService();
// Verify response received contains fake values
String actualValue = res.getBody();
String expectedValue = '{"foo":"bar"}';
System.assertEquals(actualValue, expectedValue);
}
}

Visualforce
Component-based user interface framework on Salesforce1

<apex:page StandardController="Contact” extensions="duplicateUtility”
action="{!checkPhone}”>
<apex:form>
<apex:outputField var="{!Contact.FirstName}” />
<apex:outputField var="{!Contact.LastName}" />
<apex:inputField var="{!Contact.Phone}" />
<apex:commandButton value="Update" action="{!quicksave}" />
</apex:form>
</apex:page>

Viewstate

 Apex Forms
– Visualforce component bound to an Apex Method
 Javascript Remoting
– Annotated Apex methods exposed to JavaScript
Interacting with Apex

Using JavaScript Remoting
Visualforce.remoting.Manager.invokeAction(
'{!$RemoteAction.ContactExtension.makeContact}',
“003i000000cxdHP”, “Barr”
function(result, event) {
//...callback to handle result
alert(result.LastName);
});
@RemoteAction
global static Contact makeContact
(String cid, String lname) {
return new Contact(id=cid,Last_Name=lname);
}
ApexVisualforce

Sample Success Message
{
"statusCode":200,
"type":"rpc",
"ref":false,
"action":"IncidentReport",
"method":"createIncidentReport",
"result":"a072000000pt1ZLAAY",
"status":true
}

Sample Error Message
{
"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",
"Description__c":"This is an accident report"}},
"result":null,
"status":false
}

Remote Objects
<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) {
//handle query results here
CRUD/Q Functionality Data Model Components JavaScript Framework Friendly

Summary: 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

Canvas
Framework for embedding third party apps into Salesforce

How Canvas Works
• Only has to be accessible from the
user’s browser
• Authentication via OAuth or Signed
Response
• JavaScript based SDK can be
associated with any language
• Within Canvas, the App can make
API calls as the current user
• apex:CanvasApp allows
embedding via Visualforce
Any Language, Any Platform

Using publisher.js
Sfdc.canvas.publisher.subscribe({
name: "publisher.post",
onData: function(e) {
// fires when the user hits 'Submit'
postToFeed();
}
});
Sfdc.canvas.publisher.publish({
name: "publisher.close",
payload: { refresh:"true"}
});
