Difference between Remote Action and Action Function in Salesforce

Here are some differences between apex:actionFunction and @RemoteAction.

Remote Action Function:

  • Remote Action is an Apex annotation used to mark a method as being available for javascript remoting.
  • Remote Action can call the apex methods from any apex class.
  • Remote Action allows you to call the method from javascript yourself and retrieve the result as a javascript object for manipulation.
  • Remote Action methods are static and global, hence don’t have access to your current controller variables and methods.
  • Remote Action methods require less bandwidth, and server processing time, because only the data you submit is visible and the view state is not transferred.
  • Remote Action methods have to update the DOM manually using explicit JavaScript.
  • Remote Action methods can return data directly back to the calling JavaScript, but cannot update the page’s view state.

Action Function:

  • Action Function is a Visualforce tag allows you to invoke a controller action from the Visualforce Page asynchronously via AJAX requests.
  • Action Function can call the apex methods only from the class linked to the Visualforce page.
  • Action Function doesn’t let you get retrieve data but you can rerender the page or a specific section of the page to update it with new values from the controller instance.
  • Action Function methods are instance methods, and so can see the entire page state.
    Action Function has to transfer the page view state.
  • Action Function methods automatically update the Visualforce DOM and can refresh part or all of the page, and can provide a standard interface for showing a loading status through apex:actionStatus.
  • Action Function methods can update the page’s view state, but cannot return data directly back to JavaScript (although you can do this with some extra effort using oncomplete).

In general, apex:actionFunction is easier to use and requires less code, while @RemoteAction offers more flexibility. Moreover, @RemoteAction helps in reducing View State size and also provides you near real time transaction.

Dynamic Data Creation in Salesforce From Json Data Without Using Wrapper Class

Generally for Json data insertion from external system to Salesforce, we use apex rest class and wrapper class for every object. I had a requirement to insert around 40 SF objects data from the Json data. To accomplish this requirement, I created a dynamic class, where we can insert Json data for N number of objects.

The advantage of this class is don’t need to change anything in class, If our number of object will increase or any field name will change or any field type will change. We need to change only in Custom Settings.

So, here is my article on dynamic data creation in Salesforce from json data without using wrapper class. In this article I’m going to pass Json data of Accounts & Contacts objects.

For external system data I’ve created external Id in both Account & Contact objects.

Account Object External Id Custom Field:
AccountExternalId

Contact Object External Id Custom Field:
ContactExternalId

To save SF object and Json Object information, We need to create a Custom Settings for objects.

Here is the Custom Setting Object (Json Object Mapping):
Json Object Mapping Custom Settings

Custom Setting Object (Json Object Mapping) Fields:
Json Object Mapping Fields

Custom Setting Object (Json Object Mapping) Records For Account & Contact Objects:
Json Object Mapping Records

To save SF field and Json field information, We need to create a Custom Settings for fields.
Here is the Custom Setting Object (JSon Field Mapping):
Json Field Mapping Custom Settings

Custom Setting Object (Json Field Mapping) Fields:
Json Field Mapping Fields

Custom Setting Object (Json Field Mapping) Records For Account & Contact Objects:
Json Field Mapping Records

Sample Json Data of Accounts & Contacts Objects:

{
"Account_List": {
	"Account": [{
		"External_Id": 833993,
		"Account_Name": "John"
	},
	{
		"External_Id": 833994,
		"Account_Name": "Peter"
	}]
},	
"Contact_List": {
    "Contact": [{
		    "External_Id": 100001,
			"Account_External_Id":833993,
			"First_Name":"Biswajeet",
			"Last_Name": "Samal"
		},
		{
			"External_Id": 100002,
			"Account_External_Id":833994,
			"First_Name":"Abhijeet",
			"Last_Name": "Samal"
		}]
	}
}

Dynamic apex rest class:


//URL Mapping
@RestResource(urlMapping='/ApplicationProcess/*')
global with sharing class ApplicationProcess{

    @HttpPost
    global static ApplicationResponseMsg parseApplicationJSON() {

        //Application Response Message

To test the rest class, here is the snapshot to call the apex rest class from Workbench Rest Explorer.
WorkBench Apex Rest Execute

After successfully execute the rest class with Accounts & Contacts Json data.

Created Account Records:
Account Records

Created Contact Records:
Contact Records

Note: This is the sample class. For better performance and to accomplish your requirement you can modify this class.

How to redirect to the same VF page from the Constructor with parameters in Salesforce?

Sample Code:

Apex Class:

public with sharing class SampleClass{

    public SampleClass(){
    
    }
    public PageReference doRedirect(){
        String param = ApexPages.currentPage().getParameters().get('UserId');
        if(param == null || param == ''){
            String userId = UserInfo.getUserId();
            PageReference pageRef = new PageReference('/apex/TestPage1');
            pageRef.getParameters().put('UserId',userId);
            pageRef.setRedirect(true);
            return pageRef;
        }
        else{
            return null;
        }
    }
}

VF Page:

<apex:page controller="SampleClass" action="{!doRedirect}">
	<h1>Congratulations</h1>
	This is your new Page
</apex:page>

How to redirect to a different VF page from the constructor with parameters in Salesforce?

Sample Code:

Apex Class:

public with sharing class SampleClass{
