Prompt Share - Create Contact Controller

[craigathon]

The Prompt Asked in Einstein Sidebar
Create an apex class named ContactController with an @AuraEnabled Apex method called "createAccountAndContact" that collects the following fields as an object class named AccountContact:
existingAccountId
companyName
firstName
lastName
streetAddress
city
state
postalCode
email
phone

The AccountContact class should be defined in the class. If existingAccountId is null, create a new account.

The Result

public with sharing class ContactController {
    @AuraEnabled
    public static void createAccountAndContact(AccountContact ac) {
        try {
            if (ac.existingAccountId == null) {
                Account a = new Account();
                a.Name = ac.companyName;
                a.BillingStreet = ac.streetAddress;
                a.BillingCity = ac.city;
                a.BillingState = ac.state;
                a.BillingPostalCode = ac.postalCode;
                insert a;
                
                Contact c = new Contact();
                c.AccountId = a.Id;
                c.FirstName = ac.firstName;
                c.LastName = ac.lastName;
                c.Email = ac.email;
                c.Phone = ac.phone;
                insert c;
            } else {
                Account a = [SELECT Id FROM Account WHERE Id = :ac.existingAccountId];
                Contact c = new Contact();
                c.AccountId = a.Id;
                c.FirstName = ac.firstName;
                c.LastName = ac.lastName;
                c.Email = ac.email;
                c.Phone = ac.phone;
                insert c;
            }
        } catch (Exception e) {
            throw new AuraHandledException(e.getMessage());
        }
    }

    public class AccountContact {
        @AuraEnabled
        public String existingAccountId { get; set; }
        @AuraEnabled
        public String companyName { get; set; }
        @AuraEnabled
        public String firstName { get; set; }
        @AuraEnabled
        public String lastName { get; set; }
        @AuraEnabled
        public String streetAddress { get; set; }
        @AuraEnabled
        public String city { get; set; }
        @AuraEnabled
        public String state { get; set; }
        @AuraEnabled
        public String postalCode { get; set; }
        @AuraEnabled
        public String email { get; set; }
        @AuraEnabled
        public String phone { get; set; }
    }
}

Thoughts

• Similar to the Product Registration example, we demonstrate collecting many fields and the time you can save. The time a person can save by having the tedious work done quickly, now you can focus on the details.
• This prompt was interesting because I wanted to test blending input fields of the Account and Contact and see how well the model sorted out what goes where. This appears to be a pretty good solution.
