查询异常SQLSTATE[42S22]：未找到列： 1054未知列'customers.id'在'其中条款'

Question

我想在laravel系统中编辑我的数据，该系统有一个客户id作为增量密钥。但错误是，

Illumb\Database\QueryException（42S22）SQLSTATE[42S22]：未找到列：“where子句”中的1054未知列“customers.id”（SQL:select*fromcustomerswherecustomersid=4限制1）

以前的例外

SQLSTATE[42S22]：未找到列：“where子句”（42S22）中的1054未知列“customers.id”

我不明白为什么。

我已尝试在我的模型中添加受保护的primarykey is customer_id。但结果和以前一样。

这是我的控制器

    {
        $customer = \App\Customer_Model::find($customer_id);
        $customer->delete();
        return redirect('/customers')->with('sukses', 'Users has been deleted!');
    }

这是我的模型

namespace App;

use Illuminate\Database\Eloquent\Model;

class Customer_Model extends Model
{
    protected $table = 'customers';
    protected $primarykey = 'customer_id';
    protected $fillable = ['customer_id', 'customer_code', 'customer_name', 'email', 'phone', 'contact_person', 'address', 'user_id', 'created_by', 'updated_by', 'void'];
}```

This is my view
```<tbody>
                      @foreach($data_customer as $cust)
                        <tr>
                        <td>{{$cust->customer_code}}</td>
                        <td>{{$cust->customer_name}}</td>
                        <td>{{$cust->email}}</td>
                        <td>{{$cust->phone}}</td>
                        <td>{{$cust->contact_person}}</td>
                        <td>{{$cust->address}}</td>
                        <td><a href="/customers/{{$cust->customer_id}}/edit" class="btn btn-warning"><span class="icon-settings icons icon"></span></a><a href="/customers/{{$cust->customer_id}}/delete" class="btn btn-danger"><span class="icon-trash icons icon"></span></a></td>
                        </tr>
                        @endforeach
                      </tbody>```

将$primarykey更改为$primarykey。变量区分大小写，Laravel正在查找$primaryKey（大写字母“K”）
