                                            <div class="event-pop-info">
                                                <p class="badge"></p>
                                                <p class="publisher">by <strong><?php $id = $product->user_id; $users = $user->findOrFail($id); echo $users->first; ?> <?php echo $user->last ?></strong></p>
                                            </div>
                                        </a>
                                        <a href="event-details.html">
                                            <img alt="340x230" class="card-img-top img-responsive h-100" data-holder-rendered="true" src="image/products/product.jpg"> </a>
                                        </div>
                                        <div class="card-body h-50">
                                            <h4 class="card-title">
                                                <a href="/product/"></a>
                                            </h4>
                                            <p class="card-tex" style="overflow: hidden"></p>
                                            <div class="card-event-info">
                                                <p class="event-location"><i class="fas fa-location-arrow"></i>
                                                    <a class="location" href="/user/product/"><?php echo $users->first; ?> <?php echo $user->last ?></a></p>
                                                <p class="event-time"><i class="fas fa-calendar-alt"> </i></p>
                                            </div>
                                        </div>
                                </div>
                             </div>
                           @endforeach

and this is my controller

    public function index()
{
    $user = User::find(1);
    $products = product::orderBy('created_at', 'desc')->Paginate($perPage = 15, $columns = ['*'], $pageName = 'page', $page = null);
    return view('welcome', compact('products', 'user'));

}

like you can see in my view i have this code

<?php $id = $product->user_id; $users = $user->findOrFail($id); echo $users->first; ?> <?php echo $user->last ?>

that make me able to get the name of the user that create this product ,product and user table have one to many relations.i want to change this code to a better and smaller code.

product->user->first

dont work. i tried it so many ways but that just dont work. if anyone can help me to get data with laravel way i will be greatfull.(sry if my question is duplicate, I tried so many ways but didn't work ) to give u guys more info this is my class

class User extends Authenticatable
{
use Notifiable;
use Friendable;

protected $fillable = [
    'first','last', 'email', 'password','phone','question','answer','description',
];

protected $hidden = [
    'password', 'remember_token',
];


public function products()
{

    return $this->hasMany(Product::class);

}

}  

and product class :

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class product extends Model
{

protected $fillable = [
    'part_id', 'smalldescription', 'description', 'pname', 'link', 'price',
];

public function users()
{

    return $this->belongsTo(User::class);

}





}
