Resource Controllers Index() versus Show()

I have noticed that the index method of my resource controller returns all of the relationships that I request in the index method but returns none of the relationships in the show() method.

I always assumed that the protected $records variable was filled with the table data and its relationships and was used by the remained of the methods but I was VERY wrong.

Below is my resource controller and I would like to know if there are better templates to follow to eliminate having to recreate the ->with() from the index method for the show() method. Unlike the example below, often this grows VERY large and I don't want to have to "remember" to update the with() for both methods. Thanks!!

<?php

namespace App\Http\Controllers;

use App\User;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Input;

class UsersController extends ApiController
{
    protected $records;

    public function __construct(User $records)
    {
        $this->records = $records;
    }

    public function index()
    {
        // show all
        $records = User::with('addresses', 'location', 'role', 'phones')->get();
        return $records;
    }

    public function destroy($id)
    {
        // delete single
        $record = $this->records->findOrFail($id);
        $record->delete();
        return $this->respondOK('User was deleted');
    }

    public function show($id)
    {
        //show single
        $record = $this->records->findOrFail($id);
        return $record;
    }

    public function store()
    {
        // insert new
        $record = User::create(Input::all());
        return $this->respond($record->id);
    }

    public function update($id)
    {
        // save updated
        $record = $this->records->find($id);

        if(! $record){
            User::create(Input::all());
            return $this->respond($record);
        }

        $record->fill(Input::all())->save();
        return $this->respond($record);
    }
}
