Create Remote Site Setting through Visualforce Page

Hey Salesforce Ohana, I am back with new blog post. In this blog I will explain How to create a Remote Site Setting through coding.

Most of developer or admin usually create Remote Site Setting through Remote Sites Section [Administer -> Security Control -> Remote Site Settings] in your Salesforce organization.

If you do not know what is Remote Site Setting?

Why we use Remote site setting?

You can refer this blog post for complete details.

Now it’s time for coding.

Coding

Before starting , you should know about MetaData API .

A Secrete key to access, create your salesforce.com Metadata like Workflows, Remote Site, Validation Rules.

Let’s download MetaData WSDL File [Build -> API -> MetaData WSDL] and generate apex class using this WSDL File [Build -> Develop -> Apex Classes -> Generate from WSDL] or you can refer this MetadataService apex class.

1st

Add your Salesforce Organization domain name and your visualforce page domain name in Remote site setting by following steps.

[Administer -> Security Control -> Remote Site Settings]

Now, Create a Visualforce Page for input Remote site details and apex controller for business logic.

Below is your apex controller code which will call MetaDataPort Method in the MetaDataService apex class for generating of session Id your salesforce organization and enter remote site details and call createMetaData() method.

2nd

You can refer the complete code here.

Happy Coding 🙂

 

 

 

Apex Trigger – What is Recursion and Solutions to Avoid Recursion in Apex Trigger

Before moving on to Recursion in Apex, one needs to understand what is Apex Trigger.

Apex Trigger – Apex Trigger is a piece of code that executes Before and After a record is Inserted, Updated, Deleted in a Database.

Triggers are majorly used to Modify Same Records and Create or Updates Related Records, and configure Follow up Emails on Record Creation.

In order to take understanding as how “Apex Triggers” work and what other things we can do using “Apex Triggers” please refer to the following URL.

http://www.vinaychaturvedi.com/blog/apex-triggers-in-salesforce

Once we have understanding as how Apex Triggers work we need to avoid “Recursion” in it.

What is“Recursion” in Apex Trigger?

Recursion is when same code is executing again and again & it exceeds the “Governor Limit”.

When Trigger is called Over and Over and It Exceed the Maximum Trigger Depth that is Called Recursive Trigger.

If we Try to Insert Account After Insertion of Account Using Trigger Then it Call again & again and Exceed the Governor Limit (Maximum Trigger Depth) and gives Exception

trigger RecursionExample on Account (After Insert) {

if(Trigger.isAfter&&Trigger.isInsert){

Account acc = new Account(Name = 'Recursive Account');

Insert acc;

}

}

2nd

This is common mistake that most of the Developers do, let us move to a Solution for the same.

How to Avoid Recursion or How can we Write Recursion Free Apex Trigger?

Write Apex Handler Class with Static Boolean Variable and Method and return true if Boolean Variable is true otherwise False .

Check in Apex Trigger if Handler class Method Return True Then Execute your Logic

public Class HandlerClass{

public static booleanRecursionHandler = True;

public static booleanHandlerMethod(){

if(RecursionHandler){

RecursionHandler = False;

return true;

}

else{

return RecursionHandler;

}

}

}

Apex Trigger in Which Handler Class Called.

trigger RecursionExample on Account (After Insert) {

if(Trigger.isAfter&&Trigger.isInsert){

if(HandlerClass.HandlerMethod()){

Account acc = new Account(Name = 'Recursive Account');

Insert acc;

}

}

}

OR

If you do not want to use Handler Class Method thenWrite Apex Handler Class with Static Boolean Variable and Check Handler Class Variable in Apex Trigger IF it is True then Execute Your Logic and Make it false So that Trigger Can not execute Again.

public Class HandlerClass{

public static boolean RecursionHandler = True;

}

 

trigger RecursionExample on Account (After Insert) {

if(Trigger.isAfter&&Trigger.isInsert){

if(HandlerClass.RecursionHandler){

HandlerClass.RecursionHandler = False;

Account acc = new Account(Name = 'Recursive Account');

Insert acc;

}

}

}

 

 

 

How to Tackle View State Issue During Upload file as a Attachment through Visualforce Page

In Previous Post, We Saw How to Upload File in Salesforce Through Visualforce .

So This Post is just to Handle the View State Error Occurred During Uploading File through Visualforce.

1st

For Complete Detail of View State Refer Link .

If you look into the Previous Post there were many Variables in Apex Controller which were use for getting file Body, Name, Description .

2nd

3rd

So If User Upload Large File Then file Body, Name and Description Come in these variables and It would Easily Increase the Heap Size Limit and View State Issue would arise.

4thSo For Avoiding this Issue Directly Make a Attachment Object Instance in Apex Controller and Get Body, Name of File From Visualforce Using that Instance .

5th

6th

Instead of Storing file body, Name, Description in these variables in apex controller it would Store directly in SObject Attachment So Heap Size Limit will not exceed.

Please Refer the Visualforce Page and Apex Controller for More Details.







Upload File as Attachment
public with sharing class AttachmentUploadController {
public Id PageId ;
public Attachment attachment {
get {
if (attachment == null)
attachment = new Attachment();
return attachment;
}
set;
}

public AttachmentUploadController(){
PageId = ApexPages.currentPage().getParameters().get('id');
}

public PageReference upload() {
attachment.ParentId = PageId ;
attachment.IsPrivate = true;
try {
insert attachment;
} catch (DMLException e) {
ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,'Error uploading attachment'));
return null;
} finally {
attachment = new Attachment();
}
ApexPages.addMessage(new ApexPages.message(ApexPages.severity.INFO,'Attachment uploaded successfully'));
return null;
}

How to Tackle View State Issue During Upload file as a Attachment through Visualforce Page – Part 2

1st

Hello guys , I am Back with my new Blog Post . In this Post You will Learn Two things .

  • Upload file as a Attachment  Without Apex Controller
  • What is Salesforce Ajax toolkit and How you can use Ajax Toolkit for Upload File

Please Refer my Previous Blog Posts to get to know Upload file through visualforce and Tackle View State Issue through apex Controller

First of all Do you Know about Salesforce Ajax Toolkit ???q-590x446

If you don’t know then do not worry just take long breath and read this artical.

Let’s come to the Point and discuss What is Salesforce Ajax Toolkit ?????

Ajax Toolkit is like a Javascript Wrapper which you can use in Your Visualforce Page to Interact with Salesforce Standard and custom Objects .

You can query Salesforce Objects Data , Create records and attachments without using Apex with your Visualforce Page.

Now the Questions arise When to use ajax toolkit??

Best situation to work with ajax toolkit is when you have to work with small amount of data.

AJAX works best with  small amounts of data (up to 200 records, approximately six fields with 50 characters of data each).

You have to follow three steps for working with ajax toolkit in your visualforce Page.

  • Connecting to the API – Include Connection.js file that is ajax toolkit Javascript file in your Visualforce Page and Get the Sforce Session using sforce.connection.sessionId='{!GETSESSIONID()}’

    After execution of Connection.js script , the toolkit is loaded and a global object, sforce.connection, is created. This object contains all of the API calls and AJAX Toolkit methods, and manages the session ID.

  • Embed API Calls in Javascript – Write Javascript code for Making Instance of  Sforce Object like “new sforce.SObject(“Attachment”)” and create attachment using sforce.connection.create([attachment] .
  • Processing result – Process the Result on creation of attachment and show success or failure message .onSuccess : function(result, source) {

    if(result[0].getBoolean(“success”)) {

    // do your code whatever you want to show on success

    }

    },

    onFailure : function(error, source) {

    // do your code on failure

    }

You can go through the Salesforce Ajax Toolkit Developer Docs for more reference .

Here is the Look of your Visualforce page .

When you Load the Page .

1st

When you Clicked Upload Button Without Record ID in URL .

3rd

When you Clicked Upload Button Without Selecting File for upload.

4th

When you selected file and clicked Upload Button .

2nd

Here is the Visualforce Page Code With Ajax Toolkit.

Hope you find this helpful, in case of any queries/concerns, please post a reply or drop an email to me at [email protected] .

Visualforce – Get All Accounts Related to Name Written in Input field

To Achieve this Functionality, one needs to use Jquery.

In order to use Jquery , Upload Jquery Script as a Static resource in your Salesforce Organization and Use this Script in Visualforce Page.

In order to take understanding as how it works please refer to the following URL.

Here is the Controller and Visualforce Page.







Account Name : 






















 

public with sharing class FindAccountRelated_To_Search_Ext {

public String AccName {get;set;}
public List AccountList {get;set;}

public PageReference RelatedAccounts(){

return null;
}

public List getAllAccounts(){

AccountList = [Select ID,Name From Account Where Name LIKE : ('%'+AccName+'%') ];
return AccountList;
}

}

Some points which you should know for this Visualforce Page.

1 – Use Input Field for Name of Account.

2 – Use Pageblock Table or DataTable For Display Records.

3 – Use Keypress  Jquery Event to Get the Input.

4 – Use Action function to Send the Input Value to Controller.

5 – Use SOQL Query In controller to Get All Related Records as Written in Input Field.

 

Please Follow if you like my Blog and share your valuable inputs.

 

 

 

Upload File – Upload file as an Attachment OR as a Salesforce File Related to Particular Object using Visualforce Page

Visualforce Page for Upload File as an Attachment OR in Chatter.

2ndTo Upload file as an attachment or as a file using Visualforce,one must have Record Id so that the Uploaded file links with that Record.

In Order to use Bootstrap, JQuery or CSS for Designing purpose you can refer to the following link to access Script files

https://drive.google.com/open?id=0B55QW3bpdoFPYkpyWXZJOE1rZFU

Upload this Zip file as a static Resource in your Salesforce Org and use it in Visualforce Component.

1st











Now Use this Component in your Visualforce Page and use some Apex Input and Output Tags.

  1. to get File title and to get File Description as Input from User .
  2. for choose attachment file.
  3. to Save Attachment .
  4. Jquery function to show to name of file.







Upload File as Attachment

In order to Insert file as an Attachment Related to Record Just make the instance of Attachment Object and put the Values Like File Title, File Description, Body, Related Record Id.

In Order to Insert file as Salesforce File, first of all we need to make the Lookup field for particular Object with related list in which we want to insert file in Content Version. Please refer to the steps I have performed “I have created 2 Lookup fields in Lead and Account Objects”.

To create Lookup fields in Content Version

Salesforce Files -> Create, Modify, Delete custom fields –> New Field

3rd

4th

5th

After creating this Lookup Field Make Instance of Content Version and put Required Fields as we did for Attachment.

Please refer to the controller for more details.

public with sharing class UploadFileController {

Public Id PageId {get;set;}
public Blob AttchBody {get;set;}
public String AttchDesc {get;set;}
public String AttchName {get;set;}
Public Attachment attch {get;set;}

public UploadFileController(){

PageId = ApexPages.CurrentPage().getParameters().get('Id');

}

public PageReference Upload(){

attch = new Attachment(ParentId=PageId,Description=AttchDesc,Name=AttchName,Body=AttchBody);

try{
insert attch;
AttchBody = null;
AttchDesc = null;
AttchName = null;
}
catch(Exception ex){
ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,ex.getlineNumber()+' '+ex.getMessage()));
return null;

}
ApexPages.addMessage(new ApexPages.message(ApexPages.severity.INFO,'Attachment uploaded successfully'));
return null;
}

public PageReference UploadChatterFile() {


ContentWorkspace cw =[SELECT Id FROM ContentWorkspace WHERE DeveloperName = 'Test_Workspace'];

ContentVersion v = new ContentVersion();
v.versionData = AttchBody;
v.title = AttchName;
v.FirstPublishLocationId = cw.Id;
v.pathOnClient = AttchName;

If(PageId.getSObjectType() == Account.sObjectType){
v.Account__c = PageId;
}
If(PageId.getSObjectType() == Lead.sObjectType){
v.Lead__c = PageId;
}

v.Description = AttchDesc;

try{
insert v;
AttchBody = null;
AttchDesc = null;
AttchName = null;
}
catch(Exception ex){
ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,ex.getlineNumber()+' '+ex.getMessage()));
return null;
}

ApexPages.addMessage(new ApexPages.message(ApexPages.severity.INFO,'Attachment uploaded successfully in Chatter'));
return null;
}
}

Now Login into your Salesforce Account and create a Remote Site Setting of Twilio End Point URL as given in the Twilio API Documentation

2nd

For Beginners Here is the Explanation of Remote Site Setting.

“When you want to access the external sites in your Salesforce application using callouts, web services, etc… You need to add that in the Remote Site Settings. This is just a security that force.com platform is going to check.
Before any Visualforce page, Apex callout, or JavaScript code using XmlHttpRequest in an s-control or custom button can call an external site, that site must be registered in the Remote Site Settings page, or the call will fail”

Now moving on to the Integration part, according to the Twilio voice API . We Need DEFAULT VERSION , ACCOUNTSIDAUTH TOKEN , Twilio Phone Number(From Phone Number) , Twilio Verified Phone Number(To Phone Number), Voice API End Point for Doing this Integration From Salesforce .

{
 public String mobileNumber {get;set;}
 public String responseBody {get;set;}
 public CallResponse callRes{get;set;}
 public String DEFAULT_VERSION = '2010-04-01';
 public String AccountSID = 'YOUR ACCOUNTSID';
 public String Authtoken = 'YOUR AUTH TOKEN';
 public String FromPhoneNumber = 'YOUR Twilio Phone Number';
 public String VoiceAPIEndPoint = 'https://demo.twilio.com/welcome/voice/';

 public String Body = '';

 public Void VoiceAPI()
 { 
 String Crediential = EncodingUtil.base64Encode(Blob.valueOf(AccountSID + ':' + Authtoken));
 String EndPoint = 'https://api.twilio.com/'+DEFAULT_VERSION+'/Accounts/'+AccountSID+'/Calls.json';

 if(mobileNumber != '')
 {
 Body = 'To='+mobileNumber+'&'+
 'From='+FromPhoneNumber+'&'+
 'Url='+VoiceAPIEndPoint;
 }
 else
 { 
 ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.ERROR,'Mobile Number is required.'); 
 ApexPages.addMessage(myMsg); 
 return;

 Http h = new Http();
 HttpRequest request = new HttpRequest();
 request.setHeader('Content-Type', 'application/x-www-form-urlencoded');
 request.setHeader('Authorization', 'Basic '+Crediential);
 request.setEndpoint(EndPoint);
 request.setMethod('POST');
 request.setBody(Body);
 HttpResponse res = h.send(request);
 responseBody = res.getBody();

 //------------Deserialize the Reponse in different Class------------------//
 callRes = (CallResponse)JSON.deserialize(responseBody, CallResponse.class);

 if(callRes.Status == 'queued')
 {
 ApexPages.Message myMsg = new ApexPages.Message(ApexPages.Severity.CONFIRM,'Call successfully sent..!! Please Check Entered Mobile Number'); 
 ApexPages.addMessage(myMsg);

Salesforce DX – Salesforce Developer Experience

Salesforce Developer Experience which is the most Trending Topic in these days.

SFDX is a new tool to manage and develop apps on the force.com platform. It is created for developers to build apps on force.com together in a team.

It makes the developers experience easy so that developers can do coding with less effort in a short period of time and build apps together with version control system.

It also changed the way to deploy the application on force.com platform.

Some Import features of Salesforce DX

  • Scratch Org
  • Source Sync
  • Salesforce Command Line Interface(CLI)
  • Test Runner
  • Continuous Integration
  • Force IDE and Visual Studio with DX Support

Let’s start some work on SFDX tool

Download SFDX CLI and install in your System.

Enable DEV HUB in your org so you can create scratch orgs from CLI and use this tool easily or you can create a 30 days trail org in which DEV HUB is by default activated.

Open your Command window and authorize your org

sfdx force:auth:web:login

it will redirect to salesforce login page automatically and then enter your DEV HUB org username and password.

After login you will get something like this.

1st

Check your connected orgs.

sfdx force:org:list

2nd

I have worked on these three org that’s why it’s showing these three orgs list but you will get only one org DevHub if you are using it first time.

You can check the all available things which you can do using SFDX CLI and commands list with explanation by using below two commands

Sfdx force –help

Sfdx force:doc:commands:list

Let’s create a SFDX Project

sfdx force:project:create -n ProjectName

5th

Your Project contains these files and folders.

6th

sfdx-project.json is the project configuration file contains the sfdx project information and it also tell the sfdx where to put all components when you pull data from scratch org.

7th

project-scratch-def.json is the scratch org definition file indicates which type of scratch org will be created and some basic details for scratch org like orgName or edition of Scratch org.

You can manually edit this file like replace Developer edition to Enterprise if you want to create Enterprise Edition scratch org or any other edition.

8th

Force-app folder contains all components like apex class, custom objects, visualforce pages etc..

Create a Scratch Org

sfdx force:org:create -s -f config/project-scratch-def.json -a AliasName

-s indicates this scratch org would be the default scratch org for this project.

-f indicates the path of scratch org definition file

-a indicates the alias name for this scratch org

Alias Name will be helpful when you have multiple scratch orgs. You just need to put alias name for open scratch org instead of using the username of scratch org.

9th

Open Scratch org

sfdx force:org:open

This will open the default scratch org if you have otherwise you can use alias name to open other scratch org.

sfdx force:org:open –u AliasName

10th

Create a Apex class in your project

sfdx force:apex:class:create -n ApexclassName -d force-app/main/default/classes

-n indicates the Apex class Name

-d indicates the Path for Apex class in your project

11th

Open Apex class in your project and do some thing and push all changes to scratch org

12th

Push all changes to Scratch org

sfdx force:source:push

13th

Let’s review it in the scratch org

Login in to the scratch org by sfdx force:org:open using SFDX it will automatically open your scratch org or you can get list of orgs to know the details of all connected orgs and scratch orgs.

14th

Let’s do some change in the apex class from Scratch org and pull changes you your project.

This Is the way you can sync all changes with your project to scratch orgs.

sfdx force:source:pull
