Trying to get property of non-object foreach blade in laravel 5.7

Question

I am trying to access my course information from a foreach, but it shows this error: Trying to get property of non-object.

I tried to access the information as follows: $purchase->course->name also like this:
$ purchase[course][name] but does not show any results, I have attached my model, my controller and my view.

Model:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Purchase extends Model
{   
    protected $fillable = [
            'transaction_id',
            'user_id',
            'course_id',
            'status',
            'total'
    ];

    public function courses()
    {
        return $this->belongsTo(Course::class,'course_id');
    }
}

Controller:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Purchase;

class PurchaseController extends Controller
{
    public function index()
    {  
        $purchases = Purchase::with('courses')->get();
        return view('purchases.index',compact('purchases'));
    }
}

View:

@foreach($purchases as $purchase )
 {{$purchase->course->name}}
@endforeach

if show only the variable like this $purchase all the data appears but when trying to access the course $purchase->course it shows nothing. In the controller it works fine only not works in blade view.

Answer 1

{{ $purchase->course->name }}

Should be:

{{ $purchase->courses->name }}

Your function name is courses() which means the attribute name is courses, not course.
