QueryException SQLSTATE [42S22]：找不到列：1054“ where子句”中的未知列“ customers.id”

Question

我想在laravel系统中编辑数据，该系统具有一个customer_id作为增量键。 但是错误说

Illuminate \\ Database \\ QueryException（42S22）SQLSTATE [42S22]：找不到列：1054“ where子句”中的未知列“ customers.id”（SQL：从* where customers选择* customers = id 4限制1）

以前的例外

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

我不明白为什么。

我试图在模型中添加受保护的主键customer_id。 但是结果和以前一样。

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!');
    }

这是我的模特

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>```

Answer 1

将$primaryKey更改$primarykey $primaryKey 。 该变量区分大小写，Laravel正在寻找$primaryKey （大写的“ K”）
