php - Facade\Ignition\Exceptions\ViewException 试图获取非对象的属性“名称”

Question

我有一个错误，我不知道如何解决它。我尝试添加?? ""后$customer->name不起作用。

lluminate\Foundation\Bootstrap\HandleExceptions::handleError C:\laragon\www\zorland-app\resources\views/invoices/create.blade.php:33

创建.blade.php

<div class="float-left col-md-6">
             Odaberi kupca: <b>{{ $customer->name  }}</b>
            <input type="hidden" name="invoice[customer_id]" value="{{ $customer->id }}" />
</div>

客户.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Customer extends Model
{
    //

    protected $fillable = ['name', 'address', 'postcode', 'city', 'state', 'country_id', 'postcode', 'phone', 'email'];

    public function customer_fields() 
    {
        return $this->hasMany(CustomersField::class);
    }
    public function country()
    {
        return $this->belongsTo(Country::class);
    }
