In few previous articles, I have talked about how to use “ANT Migration tool in Salesforce” and “How to Use EGit plugin in Eclipse to work with Git“. So to make this article short, I assume that you are already familiar with ANT Migration tool provided by Salesforce and Git.
During project development life cycle it is very essential to backup your code and Configurations daily. However sometimes developers forgot to commit changes in Git, may be because of workload. It may create an issue if someone wants to check back history of code for that duration, there will be no use of having code repository in place if it cant help us to get out of problem.
In this article, I will move one step further and explain how to setup automated script which will run on your System startup and commit backup of your Salesforce organization into local Git repository without any manual interference.
Salesforce Automated Script for Data Backup Using CommandLine
Previously we have seen, How to setup SAML based Single Sign On Where Salesforce will be Service Provider and some other application like AXIOM will be Identity Provider. In this article we will use one Salesforce Instance as Identity Provider and other Salesforce Instance as Service Provider.
Before starting you have to decide which salesforce Instance will act as Identity Provider and which one will act as Service Provider. To Avoid confusions, we can create app with different Logo to distinguish Identity Provider and Service Provider like I did.
Step 1 : Enable Domain in Identity Provider Organization
From Setup, click Domain Management | My Domain, enter a new subdomain name, and click Check Availability. If the name is available, click the Terms and Conditions check box, then click Register Domain. Continue reading
In this post we will discuss on creating Progress bar field without any coding, just by using formula field. Initially it seems like we can’t create dynamic progress bar field by using only formula in Salesforce. There are some approach, where developers stores 4 images with interval of 25% or 10 images with 10% interval and displaying image with help of Case or IF statement.
We will create Progress bar field, which will reflect every percentage.
Progress Bar using Formula field in Salesforce
To create perfect Progress bar field, we will need to take help of two images. Continue reading
171 : How Standard Fields and Custom Fields related information is saved inside Salesforce Database? Is every Standard and Custom Object is created as a different Database table?
Salesforce is using Multitenant architecture, means many organizations (Tenants) are using same infrastructure. Salesforce Database saves Metadata Information in hundreds of table. Run time engine then generates organization specific query to get information about their organizations and Data from common table as shown in below diagram. Below Database tables are partitioned by Organization ID and generates virtual table specific to Org.
Salesforce Metadata Related Information in Database
172 : As a Developer, how can you optimize SQL query to fetch data from Salesforce Database?
As Salesforce doesn’t save data in traditional way. Data of all tenants are in common table, so traditional Query optimization query and technique will not work in this case, so there is no such tool available to optimize final generated SQL. We only have option to create SOQL which is optimized by custom inbuilt Force.com Query Optimizer.
173 : When records are created in Salesforce, How it is queued for Indexing?
If newly created records are equal to or less than 9000, then it will be indexed in 1 to 3 minutes. However if records are more than 9000, then servers perform bulk indexing at a lower priority, so processing might take longer. Continue reading
There may be scenario in Salesforce that you need to send a Visualforce page rendered as PDF as a part of Email Attachment. This will be very easy if you want to perform this using Controller or Extension class, we just have to call getContentAsPDF() method of PageReference class and use returned blob data as a attachment in Email.
However, If we are talking about achieving same in Trigger then it would be problem. Trigger does not support getContent() method of PageReference class. If you are thinking to use getContent() in future call then again you are not lucky, because @future methods does not support it. Also Apex job doesn’t support this method.
Now, I hope you understood that in which situation we are
So, In this article, I am going to explain how to resolve this issue. Not exactly resolve but workaround for above problem.
Solution is very simple, We will expose apex method as a REST API. Code for sending email will be written in APEX based REST API and our Trigger will call this method asynchronously using @future annotation. Continue reading
In this post, We will be dicussing how to setup Federated SAML based Authentication in Salesforce.
SAML stands for “Security Assertion Markup Language” and it is Open standard for exchanging Authentication and Authorization between Systems. SAML based authentication is supported by all editions of Salesforce.
User Validation can be initiated by any one of below two types:
- Service Provider Initiated SSO
- Identity Provider (IDp) initioated SSO
We are going to use Identity Provider Initiated SSO in this article. Means User will Login from Outside(IDp) and will be redirected to Salesforce (Service Provider). Identity Provider must follow Federated Authentication (SAML) standard which should be deployed to DMZ (URL should be publicly accessible on Internet) layer of your Organization. As a Salesforce developer you should assume that you will always get IDp URL which implements SSO and implements valid SAML response. To Quickly start with this tutorial assume that your organization already deployed SAML based Authentication endpoint and for that we will be using great Heroku app available freely as open source named “AXIOM“.
AXIOM is java based heroku application which implements SAML and can be used for testing purpose to check whether SSO is working properly or not.
IDp Initiated Single Sign On :
In IDp Initiated SSO, User Directly logins to Identity provider and IDp redirects user to proper Salesforce Instance with SAML assertion in request (Service Provider). If SAML assertion is valid then Salesforce validates that user successfuly. Continue reading
We all are well aware about PageLayout and Visualforce Pages. From API 29 (Winter 14 release), Salesforce has introduced new functionality in platform named “FlexiPage”. Like Pagelayout, We can add Custom components in Flexipage however Flexipage will be visible only in Salesforce1 application in sidebar.
We can use Flexipage to make custom Homepage for some product which will be accessed directly from Salesforce1. One important thing to note here is that, till date (at the time of writing this tutorial) Flexipage can be defined in XML file and then deploying it using Eclipse, Ant Migration tool, workbench or any other migration tool. There is no way to define Flexipage directly in Salesforce using point and click functionality.
Step1 : Defining XML file for Flexipage containing detail of components
Filename – “AccountFlexi.flexipage” Continue reading
What is REST API ?
In my words, Getting data from Other System or Same System using HTTP request is known as REST API.
If you know, how website works, you know REST API. Before REST API, there was SOAP request which needed lots of configuration and very tightly coupled. If you make any modification , you had to modify client side also by generating stubs / proxy classes again. There were many more disadvantages which got address by REST API. However, it doesn’t mean we don’t need SOAP.
Back to REST API, It is very simple to setup and almost any programming language can make HTTP request so very easy to get data from other source. Return type of REST API can be XML, Simple HTTP, JSON or any media like image. However, JSON is very popular response type amongst all.
In Past, I have already written one article demonstrating REST API usage.
How to use Salesforce REST API using JQuery in Visualforce ?
REST API Playground : I have created Simple Visualforce page, which demonstrates how to use REST API of Salesforce. It is written in Visualforce with the help of JQuery. You can study this code and play with it in your organization, you just need to copy and paste it.
You also need to add URL “http://cdnjs.cloudflare.com” in Remote Site Settings, so that salesforce will allow Visualforce page to get JQuery library from CDN.
Prerequisite Libraries :
- Bootstrap CSS
This post used “Custom Service”, so please read this article to understand Dependency Injection in AngularJs.
Searching Sorting and Pagination in Table using AngularJS
In this series, we have gone through many articles on AngularJs. This time I will discuss about Dependency Injection in AngularJs .
Dependency injection is a software design pattern that allows the removal of hard-coded dependencies and makes it possible to change them, whether at run-time or compile-time.
Before going to DI first we have to know about Service.
What is Service , factory or Provider in AngularJs?
They all are same, with different way of writing. This (Singleton design pattern) defines dependency between your controller and View through application.
We can Inject a service in Controller, which will watch over changes automatically and change its View as per required.
We have many inbuilt standard service available like $scope, $filter. All inbuilt services in AngularJS starts with this sign $. In same way we can create our own custom service and then inject in Controller. Continue reading
