Laravel one to many relationship doesn't work anymore - php

Question

This relationship of mine was working last week, but it stopped working.
When i use it in my blade template it says: Trying to get property 'name' of non-object.
The weird thing is, when i use it in dd() it perfectly shows, but when i try to print it in blade, it doesn't.
Code PaymentsController
<?php
namespace App\Http\Controllers;
use App\Betaling;
use App\Settings;
use Illuminate\Http\Request;
class PaymentsController extends Controller
{
public function index(){
$user_id = auth()->user('id');
$role = auth()->user()->role_id;
$settings = Settings::where('user_id', $user_id->id)->first();
if ($role === 1){
$totaalaantalbetalingen = Betaling::all();
} else {
$totaalaantalbetalingen = Betaling::where('user_id', $user_id->id)->get();
}
return view('payments.index', compact(['totaalaantalbetalingen','role', 'user_id', 'settings']));
}
}
Code index.blade.php
#foreach($totaalaantalbetalingen as $betaling)
<tr>
<th scope="row">{{ $betaling->id }}</th>
#if($role === 1)
<td>{{ $betaling->user->name }} </td>
#endif
<td>{{ $betaling->customer->name }}</td>
<td>{{ $betaling->reference}}</td>
<td>€ {{ $betaling->amount}}</td>
<td>{{ $betaling->time_of_invoice }}</td>
<td>{{ $betaling->time_of_payment }}</td>
<td></td>
<td>{{ $betaling->user->location }}</td>
</tr>
#endforeach

Answer 1

pass auth()->user()->id and in blade file check !empty($totaalaantalbetalingen)
code User model:
public function betalingen(){
return $this->hasMany('App\Betaling','betalingenid','id'); // pass foreign key for ex.
}
code Betaling model:
public function customer(){
return $this->belongsTo('App\User','customer_id','id');// pass foreign key for ex.
}
public function user(){
return $this->belongsTo('App\User','user_id','id');// pass foreign key for ex.
}
code Customer model:
public function betaling(){
return $this->hasMany('App\Betaling','customer_id','id');// pass foreign key for ex.
}
Controller
public function index(){
$user_id = auth()->user()->id;
$role = auth()->user()->role_id;

$totaalaantalbetalingen = Betaling::all();
} else {
$totaalaantalbetalingen = Betaling::where('user_id', $user_id)->get();
}
return view('payments.index', compact(['totaalaantalbetalingen','role', 'user_id', 'settings']));
}
