Counting Child Record data for use with LWC

Hello, I am having trouble finding a way to pull aggregate data from the below Apex class that I have for a component being built. We need to record the count of Id's and Total units from the child record ChildAccounts. I am relatively new to coding and so any information and help would be greatly appreciated!
  
public with sharing class GetAccountContactData {
    @AuraEnabled(cacheable=true)
    public static List<Account> getAccountData() {
        return [SELECT Id, Name, 
        (SELECT Id, Name, Email, Phone, Title FROM Contacts), 
        (SELECT Id, Name, Region_picklist__c, Total_Units__c FROM ChildAccounts) 
        FROM Account WHERE Active__c = TRUE AND RecordTypeId = '0122K000001Dio1QAC' ORDER BY Name];
    }
}

Hi

You can take references from the below code.

<aura:component controller="accountsWithContactsClass" implements="flexipage:availableForAllPageTypes" access="global">
    <aura:handler name="init" value="{!this}" action="{!c.myAction}"/>
    <aura:attribute name="accounts" type="Account[]" />
    <table>
        <tr>
            <td>
                <b>Name</b>
            </td>
            <td>
                <b>Industry</b>
            </td>
            <td>
                <b>Contacts</b>
            </td>
        </tr>
        <aura:iteration items="{!v.accounts}" var="accs1" >
            <tr>  
                <td> {!accs1.Name}  </td>
                  <td> {!accs1.Industry}  </td>
                 <!--   <td>   {!accs1.Contacts.lastName}  </td> -->
                <table>
                    <aura:iteration items="{!accs1.Contacts}" var="con1" >
                        <tr>
                            <td>{!con1.LastName}</td>
                        </tr>
                    </aura:iteration>
                </table>
            </tr> 
         </aura:iteration>                                           
    </table>    
</aura:component>
  
({
	myAction : function(component, event, helper) {
		var action =component.get("c.getAllAccounts");
        console.log('The action value is: '+action);
         action.setCallback(this, function(a){ 
             
            component.set("v.accounts", a.getReturnValue());
           //  console.log('The accs are :'+JSON.stringify(a.getReturnValue()));
            console.log('The accs are :'+JSON.stringify(a.getReturnValue()));
          
        });
        $A.enqueueAction(action);
	}
})

 

public class accountsWithContactsClass {

@auraEnabled
public static list<account> getAllAccounts()
    {
       list<account> accs =[select id,name,phone,industry,(select lastName from contacts) from account limit 10];
      //  list<account> accs =[select id,name,phone,industry from account limit 10];
     //   return [select Id,Name from account limit 10];
     return accs;
    }
}

Hi Chase,

You can use the JSON.stringify(data) (data return from Apex Controller) and then iterate them. 

I'm putting snippet for similar use case.

 

Apex Class :

@AuraEnabled(cacheable=true)
    public static List<Account>getAccountRelatedData(){
        System.debug('--- Related Data---');
        return[SELECT Id, Name, Industry, Type, AnnualRevenue,
               (SELECT Id, Name FROM Contacts) FROM Account  WHERE NumberOfEmployees > = 50 ];
               
    }
 





JS Controller (LWC)
 

import { LightningElement, wire, track } from 'lwc';
import getAccountRelatedData from '@salesforce/apex/AccountController.getAccountRelatedData';
export default class AccountControllerLWC extends LightningElement {
    @track accounts;
    @track error;
    @wire(getAccountRelatedData)
    wiredAccounts({ error, data }) {
        if (data) {
            this.accounts = data;
            console.log('getAccountRelatedData-->'+JSON.stringify(this.accounts));
        } else if (error) {
            console.log(error);
            this.error = error;
        }
    }
}


Hope this will give some idea.

 

Thanks!

        });
        $A.enqueueAction(action);
	}
})

 

public class accountsWithContactsClass {

@auraEnabled

     //   return [select Id,Name from account limit 10];
     return accs;
