Part 3: Creating the AccountController Class

Lightning makes it easy to work with data. In this module, you create an Apex controller that allows your Lightning components to retrieve a list of accounts with their location information.

What you will learn

• Create an Apex Controller that exposes data and logic to the client application

Steps

1. In Salesforce, click your name in the upper right corner of the screen. In the dropdown menu, click Developer Console.

   

2. In the Developer Console, click File > New > Apex Class. Specify AccountController as the class name and click OK.

3. Implement the class as follows:

   public with sharing class AccountController {
   
       @AuraEnabled
       public static List<Account> findAll() {
           return [SELECT id, name, Location__Latitude__s, Location__Longitude__s
                   FROM Account
                   WHERE Location__Latitude__s != NULL AND Location__Longitude__s != NULL
                   LIMIT 50];
       }
   
   }
   

   Code Highlights:

   • AccountController is a regular controller class with a method to retrieve a list of accounts that have location information.
   • You need to annotate your methods with @AuraEnabled to make them available to Lightning components.
