Timestamps error when ->using('PivotModel')

[projct1]

• Laravel Version: 5.5.17

Description:

class Order extends Model
{
    public function sms()
    {
        return $this->belongsToMany('App\Sms')->using('App\OrderSms')->withTimestamps();
    }
}

class Sms extends Model
{
    public $timestamps = false;

    protected $fillable = ['subject', 'template'];
}

class OrderSms extends Pivot
{
    protected $table = 'order_sms';
}

OrderSms::where('red_sms_id', $smsId)->update([
    'status' => $status
]);

As result is Call to a member function getUpdatedAtColumn() on null. I have to use:

DB::table('order_sms')->where('red_sms_id', $smsId)->update([
    'status' => $status,
    'updated_at' => Carbon::now()
]);

But ist bug! Expected behaviour is updating timestamps on OrderSms table.

@themsaid I updated code.

I also think this is a bug. @themsaid, please review.

The issue is that when you load a Pivot Model directly (like in the example above) the $pivotParent property is not set.

Then, the getCreatedAtColumn() and getUpdatedAtColumn() functions fail because they reference that $pivotParent property.

A possible solution is to return the model own timestamps when no $pivotParent is set.
