Metadata Ever want to turn off every Workflow for an

Object? Open the object’s XML file, copy the contents into a

text editor, then set <active>false</active> for everything in Eclipse, then revert back when done.

Ever want to know where a field is used? Maybe you have data being changed and you can’t

figure out why – maybe it is referenced in a field update or a trigger!

Code Examples Apex Trigger – Create a Case from an

Opportunity Visualforce – De-dupe before saving a Lead

14

Trigger Create a Case from an Opportunity

Have you ever wanted to create a project once an Opportunity is Closed/Won? Or a survey when a Case is Closed? Or create an Order when an Opportunity is Closed/Won?

15

Trigger (GOOD)List<Case> casesToInsert = new List<Case>();for(Opportunity o : Trigger.new){ //Filter out the Id or Keyword etc if(o.IsWon) { Case c = new Case(); c.Subject = o.Name; c.Description = o.Description; c.AccountId = o.AccountId; c.Oppoprtunity__c = o.Id; //You can set origin, type, status, etc

//NEVER do a QUERY or a DML (insert, update, delete, upsert) INSIDE A LOOP!!! casesToInsert.add(c); }}

//Done with the loop, what about the insert?if(casesToInsert.size() > 0){ //DO NOT do a try/catch and ignore the error //insert below will cause the entire trigger to fail if there is even 1 case with an error. //maybe this is good? insert casesToInsert;

//If you’d rather you can use Database.insert() and handle errors one at a time. //Sometimes this is good. Just don’t “hide” the errors in System.debug() statements. //throw them or email them or something!}

16

Trigger (BAD)List<Case> casesToInsert = new List<Case>();for(Opportunity o : Trigger.new){ //Filter out the Id or Keyword etc if(o.IsWon) { Case c = new Case(); c.Subject = o.Name; c.Description = o.Description; c.AccountId = o.AccountId; c.Oppoprtunity__c = o.Id; //You can set origin, type, status, etc

//NEVER do a QUERY or a DML (insert, update, delete, upsert) INSIDE A LOOP!!! insert c; //BAD! BAD!!!! }}

//Done with the loop, what about the insert?if(casesToInsert.size() > 0){ //BAD try { insert casesToInsert; } catch (Exception exp) { //This exception only goes to a log when you monitor it. No one will ever know of the error :( System.debug(exp); } }

17

Visualforce Page There are a ton of de-dupe before saving a Lead

apps out there, so don’t actually code this in a real org! But it makes for a simple example

There are lots of ways of going about this. This is how I like to do it: First set yourself up with Development Mode (see next

slide) Then, in your Salesforce org/browser enter the URL

https://naX.salesforce.com/apex/DeDupePage The wizard will walk you through creating the page!

Visualforce Page – The Page (pre Extension)

20

<apex:page standardController="Lead“ > <apex:form > <apex:pageBlock mode="edit" > <apex:pageMessages /> <apex:pageBlockButtons > <apex:commandButton value="Save" action="{!Save}" /> <apex:commandButton value="Cancel" action="{!Cancel}" /> </apex:pageBlockButtons> <apex:sectionHeader title="Lead"/> <apex:pageBlockSection title="Details" columns="1" > <apex:inputField value="{!Lead.Firstname}" /> <apex:inputField value="{!Lead.Lastname}" required="true" /> <apex:inputField value="{!Lead.Company}" required="true" /> <apex:inputField value="{!Lead.Email}" required="true" /> </apex:pageBlockSection> </apex:pageBlock> </apex:form></apex:page>

Visualforce Page If you’ve created your Visualforce Page via the

Salesforce “browser” UI then once you add an “extension” or “controller” to your Page (see next slide) Salesforce will generate the Controller shell code for you!

Then you can refresh your IDE and edit the Controller there to get type ahead and other IDE goodness

Visualforce Page – The Page (post Extension)

22

<apex:page standardController="Lead" extensions="VFC_LeadDeDupeExt" > <apex:form > <apex:pageBlock mode="edit" > <apex:pageMessages /> <apex:pageBlockButtons > <apex:commandButton value="Save" action="{!customSave}" /> <apex:commandButton value="Cancel" action="{!Cancel}" /> </apex:pageBlockButtons> <apex:sectionHeader title="Lead"/> <apex:pageBlockSection title="Details" columns="1" > <apex:inputField value="{!Lead.Firstname}" /> <apex:inputField value="{!Lead.Lastname}" required="true" /> <apex:inputField value="{!Lead.Company}" required="true" /> <apex:inputField value="{!Lead.Email}" required="true" /> </apex:pageBlockSection> </apex:pageBlock> </apex:form></apex:page>

Visualforce Page – The Controller

23

public with sharing class VFC_LeadDeDupeExt { ApexPages.StandardController stdController; private Lead currentLead;

public VFC_LeadDeDupeExt(ApexPages.StandardController controller) { stdController = controller; currentLead = (Lead)controller.getRecord(); } public PageReference customSave() { List<Lead> duplicates = [SELECT Id FROM Lead WHERE Email = :currentLead.Email]; if(duplicates != null && duplicates.size() > 0) { ApexPages.addMessage(new ApexPages.Message(ApexPages.Severity.ERROR,'Error: A duplicate email address was found with Id: ' + duplicates[0].Id)); return null; } //try //{ return stdController.save(); //} //catch (Exception exp) //{ //TODO display pretty errors //} return null; }

}

Common Force.com Terms Trigger – custom code that runs on save (like a workflow rule) Visualforce – custom code that makes the screen look however

your heart desires Batch Apex – apex code that can run on Millions upon Millions of

records Scheduled Apex – apex code that runs at a set time each day

(up to 5 times per day (shhhh - there is an exception via Developer Console)) Force.com API (SOAP) – the “old fashioned” (i.e. good) way to

integrate data into/out of salesforce Force.com API (REST API) – the “new fashioned” way to do

real-time or highspeed integrations of small transactional data Native vs Non-Native Applications – Native applications run

100% on Force.com (and if we stretch, this also means Heroku). Non-native applications require a separate server to run a portion of the code. Why write non-native? That code supports non-Salesforce use cases. That code requires massive data volumes/complexities that Force.com would otherwise limit. That code was cheaper to write in Ruby/Java than Force.com.
