- 40. What's SOQL? ▪Salesforce Object Query language ▪ Similar to SQL ▪ Streamlined syntax to traverse object relationships ▪ Built into Apex
- 41. SELECT Id, Name,Phone FROM Contact
- 42. SELECT Id, Name,Phone FROM Contact WHERE Phone <> null
- 43. SELECT Id, Name,Phone FROM Contact WHERE Phone <> null AND Name LIKE '%rose%'
- 44. SELECT Id, Name,Phone FROM Contact WHERE Phone <> null AND Name LIKE '%rose%' ORDER BY Name
- 45. SELECT Id, Name,Phone FROM Contact WHERE Phone <> null AND Name LIKE '%rose%' ORDER BY Name LIMIT 50
- 46. Details to Master SELECT Id, Name, Phone, Account.Name FROM Contact WHERE Phone <> null AND Name LIKE '%rose%' ORDER BY Name LIMIT 50
- 47. Master to Details SELECT Name, (SELECT FirstName, LastName, Phone FROM Contacts) FROM Account
- 48. Executing SOQL inthe Developer Console
- 49. Inlining SOQL inApex Integer i = [SELECT Count() FROM Session__c];
- 50. Inlining SOQL inApex String level = 'Advanced'; List<Session__c> sessions = [SELECT Name, Level__c FROM Session__c WHERE Level__c = :level];
- 51. Inlining SOQL inApex List<String> levels = new List<String>(); levels.add('Intermediate'); levels.add('Advanced'); List<Session__c> sessions = [SELECT Name, Level__c FROM Session__c WHERE Level__c IN :levels];
- 52. Inlining SOQL inApex for (Speaker__c s : [SELECT Email__c FROM Speaker__c]) { System.debug(s.email__c); }
- 53. What's DML? ▪Data Manipulation Language ▪ Language used to create, update, delete records
- 54. insert Session__c session= new Session__c(); session.name = 'Apex 101'; session.level__c = 'Beginner'; insert session;
- 55. insert Session__c session= new Session__c( name = 'Apex 201', level__c = 'Intermediate' ); insert session;
- 56. update String oldName= 'Apex 101'; String newName = 'Apex for Beginners'; Session__c session = [SELECT Id, Name FROM Session__c WHERE Name=:oldName]; session.name = newName; update session;
- 57. delete String name= 'Testing 501'; Session__c session = [SELECT Name FROM Session__c WHERE Name=:name]; delete session;
- 58. Lab 4: AccessingData using SOQL and DML ▪ Execute SOQL statements in the Query Editor ▪ Execute DML statements in the Anonymous Window http://bit.ly/sf-dev-quick
- 59. Module 5: WritingTriggers
- 60. What's a Trigger? ▪ Apex code executed on database events ▪ Before or after: – Insert – Update – Delete – Undelete
- 61. Before or After? ▪ Before – Update values before they are saved to the database – Example: Prevent double-booking of a speaker ▪ After – Validate values before they are saved – Access values set by the database (Id, lastUpdated, …) – Example: Send speaker confirmation email
- 62. Bulk Mode ▪Triggers work on lists of records, not single records ▪ This is to support bulk operations – Data Import, Bulk API, etc. ▪ Context variables provide access to old and new values: – Trigger.old and Trigger.new (List) – Trigger.oldMap and Trigger.newMap (Map)
- 63. Example 1 triggerWelcomeKit on Account (after insert) { List<Case> cases = new List<Case>(); for (Account account : Trigger.new) { Case case = new Case(); case.Subject = 'Mail Welcome Kit'; case.Account.Id = account.Id; cases.add(case); } insert cases; }
- 64. Example 2 triggeron Account (before update) { for (Account acc: Trigger.New) { // Compare new value with old value if (acc.Rating != Trigger.oldMap.get(acc.Id).Rating) { // Your Logic } } }
- 65. Workflow vs Trigger Workflow Trigger Created with Clicks Code What can it do • Update field • Send email • Create task • Send outbound message • Launch flow (flow trigger) ~ Anything (e.g. create/delete records, REST callout, etc.) Cross-object field updates Limited (detail -> master) Any
- 66. Lab 5: WritingTriggers ▪ Write the SendConfirmationEmail trigger ▪ Write the RejectDoubleBooking trigger http://bit.ly/sf-dev-quick
- 67. Module 6: WritingVisualforce Pages
- 68. What's a VisualforcePage? ▪ HTML page with tags executed at the server-side to generate dynamic content ▪ Similar to JSP and ASP ▪ Can leverage JavaScript and CSS libraries ▪ The View in MVC architecture
- 69. Model-View-Controller Model Data+ Rules Controller View-Model interactions View UI code ▪ Separation of concerns – No data access code in view – No view code in controller ▪ Benefits – Minimize impact of changes – More reusable components
- 70. Model-View-Controller in Salesforce View • Standard Pages • Visualforce Pages • External apps Controller • Standard Controllers • Controller Extensions • Custom Controllers Model • Objects • Triggers (Apex) • Classes (Apex)
- 71. Component Library ▪Presentation tags – <apex:pageBlock title="My Account Contacts"> ▪ Fine grained data tags – <apex:outputField value="{!contact.firstname}"> – <apex:inputField value="{!contact.firstname}"> ▪ Coarse grained data tags – <apex:detail> – <apex:pageBlockTable> ▪ Action tags – <apex:commandButton action="{!save}" >
- 72. Expression Language ▪Anything inside of {! } is evaluated as an expression ▪ Same expression language as Formulas ▪ $ provides access to global variables (Resource, Label, User, RemoteAction, …) – {! $Resource.JSLib } – {! $Label.MyCustomLabel }
- 73. Example: Expressions <apex:page> <apex:stylesheet value=”{!URLFOR($Resource.files,’style.css’)}”/> <h1>Hello, {!$User.FirstName}</h1> </apex:page> Important Note: Normally Visualforce tags do not support line breaks!
- 74. Standard Controller ▪A standard controller is available for all objects – You don't have to write it! ▪ Provides standard CRUD operations – Create, Update, Delete, Field Access, etc. ▪ Can be extended with more capabilities (next module) ▪ Uses id query string parameter in URL to access object
- 75. Example: Standard Controller <apex:page standardController="Contact"> <apex:form> Standard controller object Standard controller field <apex:inputField value="{!contact.firstname}"/> <apex:inputField value="{!contact.lastname}"/> <apex:commandButton action="{!save}" value="Save"/> </apex:form> </apex:page> Method in standard controller
- 76. Email Templates Embeddedin Page Layouts Generate PDFs Custom Tabs Mobile Interfaces Page Overrides Where can I use Visualforce?
- 77. Lab 6: WritingVisualforce Pages ▪ Write the SpeakerForm Visualforce page ▪ Set it as default for creating and editing speakers http://bit.ly/sf-dev-quick
- 78. Module 7: WritingController Extensions and Custom Controllers
- 79. What's a ControllerExtension? ▪ Custom class written in Apex ▪ Implements constructor with controller parameter ▪ Works on the same object as the standard controller ▪ Used to extend or override standard controller behavior
- 80. Defining a ControllerExtension in Markup <apex:page standardController="Speaker__c" extensions="SpeakerCtrlExt"> Provides basic CRUD Overrides standard actions and/or provide additional capabilities
- 81. Anatomy of aController Extension in Apex public class SpeakerCtrlExt { private final Speaker__c speaker; private ApexPages.StandardController stdController; public SpeakerCtrlExt (ApexPages.StandardController ctrl) { this.stdController = ctrl; this.speaker = (Speaker__c)ctrl.getRecord(); } // method overrides // custom methods }
- 82. What's a CustomController? ▪ Custom class written in Apex ▪ Doesn't work on a specific object ▪ Provides custom data ▪ Provides custom behaviors ▪ Can also work with an extension
- 83. Defining a CustomController <apex:page controller="FlickrController">
- 84. Custom Controller Example public with sharing class FlickrController { public FlickrList getPictures() { HttpRequest req = new HttpRequest(); req.setMethod('GET'); req.setEndpoint('http://api.flickr.com/services/feeds/'); HTTP http = new HTTP(); HTTPResponse res = http.send(req); return (FlickrList) JSON.deserialize(res.getBody(), FlickrList.class); } }
- 85. Lab 7: Writinga Controller Extension ▪ Write a Controller Extension that supports Picture Upload
- 86.
- 87. Module 8: UsingJavaScript in Visualforce Pages
- 88. Why Use JavaScript? ▪ Build Engaging User Experiences ▪ Leverage JavaScript Libraries ▪ Build Custom Applications
- 89. JavaScript in VisualforcePages Visualforce Page JavaScript Remoting Remote Objects (REST)
- 90.
- 91. JavaScript Remoting -Server-Side global with sharing class HotelRemoter { @RemoteAction global static List<Hotel__c> findAll() { return [SELECT Id, Name, Location__Latitude__s, Location__Longitude__s FROM Hotel__c]; } }
- 92. "global with sharing"? ▪ global – Available from outside of the application ▪ with sharing – Run code with current user permissions. (Apex code runs in system context by default -- with access to all objects and fields)
- 93. JavaScript Remoting -Visualforce Page <script> Visualforce.remoting.Manager.invokeAction( '{!$RemoteAction.HotelRemoter.findAll}', function (result, event) { if (event.status) { for (var i = 0; i < result.length; i++) { var lat = result[i].Location__Latitude__s; var lng = result[i].Location__Longitude__s; addMarker(lat, lng); } } else { alert(event.message); } } ); </script>
- 94. Using JavaScript andCSS Libraries ▪ Hosted elsewhere <script src="https://maps.googleapis.com/maps/api/js"></script> ▪ Hosted in Salesforce – Upload individual file or Zip file as Static Resource – Reference asset using special tags – Covered in Module 10
- 95. Lab 8: UsingJavaScript in Visualforce Pages (Workbook Module 3) ▪ Write the HotelMap Visualforce Page http://bit.ly/sf-dev-adv
- 96. Module 9: Usingthe REST APIs
- 97. When? Get accessto Salesforce data from outside Salesforce: ▪ Integrate Salesforce in existing apps ▪ Build consumer apps ▪ Device integration (Internet of Things)
- 98. Mobile SDK Example OAuth REST APIs
- 99. Browser Cross-Origin Restrictions OAuth REST APIs app.js index.html HTTP Server Cross Origin Policy
- 100. Using a Proxy OAuth REST APIs app.js index.html Proxy HTTP Server
- 101.
- 102.
- 103.
- 104.
- 105. Salesforce REST Toolkit https://github.com/developerforce/Force.com-JavaScript-REST-Toolkit
- 106. Lab 9: Usingthe REST APIs (Workbook Module 4) ▪ Create a consumer app hosted outside Salesforce http://bit.ly/sf-dev-adv
- 107. Windows Users Afterinstalling Node.js: 1. Add c:Program FilesNodejs to your path or Run "C:Program FilesNodejsnpm" install 2. Create an "npm" directory in C:Users[yourname]AppdataRoaming
- 108. Module 10: UsingStatic Resources
- 109. What are StaticResources? ▪ Files uploaded to Salesforce instance for use in Visualforce pages – .js – .css – .jpg, .png, .gif, etc. ▪ Can be uploaded individually or as archive (.zip or .jar)
- 110.
- 111. Referencing Static Resources // Single file <apex:stylesheet value="{!$Resource.bootstrap}"/> <apex:includeScript value="{!$Resource.jquery}"/> <apex:image url="{!$Resource.logo}"/> // ZIP file <apex:stylesheet value="{!URLFOR($Resource.assets, 'css/main.css')}"/> <apex:image url="{!URLFOR($Resource.assets, 'img/logo.png')}"/> <apex:includeScript value="{!URLFOR($Resource.assets, 'js/app.js')}"/>
- 112. Visualforce and HTMLPage Generation ▪ By default, Visualforce generates HTML page elements: – <html> – <head> – <body> ▪ <apex:> tags ensure corresponding HTML elements are inserted at the right place – <apex:stylesheet> – <apex:includeScript>
- 113. Controlling HTML PageGeneration ▪ You can also take full control over HTML elements generation and position: <apex:page docType="html" applyHtmlTag="false" applyBodyTag="false"> ▪ … and use standard HTML tags – <link rel="stylesheet" href="…"> – <script src="…">
- 114. Lab 10: StaticResources (Workbook Module 5) ▪ Host single page application in Visualforce page http://bit.ly/sf-dev-adv
- 115. Module 11: UsingCanvas Applications
- 116. What is aCanvas App? ▪ A web app integrated in your Salesforce environment ▪ Can be written in any language – Java, .NET, PHP, Ruby on Rails, Node.js, etc. ▪ Transparently authenticated ▪ Context aware (logged in user, current object, etc.)
- 117. Use Cases ▪Internal App ▪ Third-Party / Partner App ▪ External systems with web facade
- 118. Where Can ItBe Integrated? ▪ Publisher ▪ Page Layouts ▪ Visualforce Pages ▪ Tabs ▪ Mobile Cards
- 119.
- 120. Transparent Authentication ▪When loading Canvas app, Salesforce instance posts Base64 encoded data to app endpoint including: – Authenticated token – Context (logged in user, current object, etc) ▪ App decodes data using client secret ▪ Can use authenticated token to make REST API calls
- 121. Node.js example vardecode = require('salesforce-signed-request'); var secret = process.env.CONSUMER_SECRET; app.post('/signedrequest', function(req, res) { var signedRequest = req.body.signed_request; var decodedRequest = decode(signedRequest, secret); var oauthToken = decodedRequest.client.oauthToken; var instanceUrl = decodedRequest.client.instanceUrl; var context = decodedRequest.context; });
- 122. Lab 11: Canvas (Workbook module 6) ▪ Deploy Node.js web app to Heroku ▪ Integrate app in Contact page layout http://bit.ly/sf-dev-adv
- 123. Module 12: WritingUnit Tests
- 124. Unit Testing ▪Code to test code ▪ Increases quality and predictability ▪ Unit test coverage is required to move code to production – Must have at least 75% of code covered – Coverage = lines of code exercised by tests / total line of code
- 125. Anatomy of aTest Class @isTest private class myClass { static testMethod void myTest() { // 1. Prepare temporary data // 2. Start Test // 3. Execute some code // 4. Stop Test // 5. Assert } }
- 126. Create Temporary Data Datetime now = System.now(); // Create speaker Speaker__c sp = new Speaker__c(First_Name__c='Al', Last_Name__c='Smith'); insert sp; // Create two sessions starting at the same time Session__c s1 = new Session__c(Name='Session1', Session_Date__c=now); insert s1; Session__c s2 = new Session__c(Name='Session2', Session_Date__c=now); insert s2; // Book speaker for session1 Session_Speaker__c booking1 = new Session_Speaker__c(Session__c=s1.Id, Speaker__c=sp.Id); insert booking1;
- 127. Test and Assert Test.startTest(); // Try to book speaker for session2 Session_Speaker__c booking2= new Session_Speaker__c(Session__c=s2.Id, Speaker__c=sp.Id); Database.SaveResult result = Database.insert(booking2, false); Test.stopTest(); // Insert should fail: can't book same speaker for 2 sessions happening // at same time System.assert(!result.isSuccess());
- 128.
- 129. Lab 12: UnitTesting (Workbook Module 7) ▪ Write the TestDoubleBooking class ▪ Run the test http://bit.ly/sf-dev-adv
- 130. Module 13: Batchand Schedule
- 131. What's a Batch? ▪ Long-running process that runs without manual intervention ▪ Started programmatically
- 132. Defining a BatchJob global class SendReminderEmail implements Database.Batchable { global SendReminderEmail(String query, String subject, String body) { // Constructor: accept parameters } global Database.QueryLocator start(Database.BatchableContext bc) { // Select scope (records to process) } global void execute(Database.BatchableContext bc, List<Speaker__c> scope) { // Process data } global void finish(Database.BatchableContext bc) { // Post processing operations } }
- 133. Running the BatchJob String q = 'SELECT First_Name__c, Last_Name__c, Email__c ' + 'FROM Speaker__c WHERE Email__c != null'; SendReminderEmail batch = new SendReminderEmail(q, 'Final Reminder', 'The conference starts next Monday'); Database.executeBatch(batch);
- 134. What's Scheduled Job? ▪ Unattended background program execution ▪ Occurs at a specified time ▪ Optionally repeated at a specified interval
- 135. Defining a ScheduledJob global class ScheduledEmail implements Schedulable { global void execute(SchedulableContext sc) { String q = 'SELECT First_Name__c, Last_Name__c, Email__c ' + 'FROM Speaker__c WHERE Email__c != null'; SendReminderEmail batch = new SendReminderEmail(q, 'Final Reminder', 'The conference starts next Monday'); Database.executeBatch(batch); } }
- 136. Scheduling the Job(using Code) ScheduledEmail job = new ScheduledEmail(); // Run at 8AM on February 10th // (Seconds Minutes Hours Day_of_month Month Day_of_week Years) // Can use wildcards String schedule = '0 0 8 10 2 ?'; String jobId = System.schedule('Final reminder', schedule, job);
