Laravel - 显示名称而不是 id

Question

需要帮助，如何显示驱动程序的名称而不是 id？我有更多的表，但如果有人可以帮助我，我会更高兴，表显示 ID 1、2、3 的编号......我试图改变模型，我正在学习 php 和lavarel 仍然这部分对我来说不清楚。谢谢帮忙

注册模型；

class register extends Model
{
    use SoftDeletes;

    use HasFactory;

    public $table = 'registers';
    
    protected $dates = ['deleted_at'];

    public $fillable = [
        'driver_id',
        'inOut',
        'plates',
        'carrier_id',
        'tractorNumber',
        'process_id',
        'location_id',
        'customer',
        'drayage_id',
        'containertype_id',
        'containerstatus_id',
        'containerPlate',
        'containerNumber',
        'comments'
    ];

    /**
     * The attributes that should be casted to native types.
     *
     * @var array
     */
    protected $casts = [
        'id' => 'integer',
        'driver_id' => 'integer',
        'inOut' => 'string',
        'plates' => 'string',
        'carrier_id' => 'integer',
        'tractorNumber' => 'string',
        'process_id' => 'integer',
        'location_id' => 'integer',
        'customer' => 'string',
        'drayage_id' => 'integer',
        'containertype_id' => 'integer',
        'containerstatus_id' => 'integer',
        'containerPlate' => 'string',
        'containerNumber' => 'string',
        'comments' => 'string'
    ];

    /**
     * Validation rules
     *
     * @var array
     */
    public static $rules = [
        'driver_id' => 'required',
        'inOut' => 'required',
        'carrier_id' => 'required',
        'process_id' => 'required',
        'location_id' => 'required',
        'drayage_id' => 'required',
        'containertype_id' => 'required',
        'containerstatus_id' => 'required'
    ];

}

驱动器型号

class driver extends Model
{
    use SoftDeletes;

    use HasFactory;

    public $table = 'drivers';
    

    protected $dates = ['deleted_at'];



    public $fillable = [
        'driverName',
        'licence'
    ];

    /**
     * The attributes that should be casted to native types.
     *
     * @var array
     */
    protected $casts = [
        'id' => 'integer',
        'driverName' => 'string',
        'licence' => 'string'
    ];

    /**
     * Validation rules
     *
     * @var array
     */
    public static $rules = [
        'driverName' => 'required',
        'licence' => 'required'
    ];
    
}

  @foreach($registers as $register)
            <tr>
                <td>{{ $register->driver_id }}</td>
            <td>{{ $register->inOut }}</td>
            <td>{{ $register->plates }}</td>
            <td>{{ $register->carrier_id }}</td>
            <td>{{ $register->tractorNumber }}</td>

Answer 1

如果驱动程序和注册模型之间存在关系，您可以在注册模型类中编写该关系。

public function driver()
{
    return $this->belongsTo(driver::class, 'driver_id');
}

然后就可以通过输入获取驱动名称了，

@foreach($registers as $register)
            <tr>
                <td>{{ $register->driver->driverName}}</td>
                <td>{{ $register->inOut }}</td>
                <td>{{ $register->plates }}</td>
                <td>{{ $register->carrier_id }}</td>
                <td>{{ $register->tractorNumber }}</td>
           </tr>
 @endforeach()
