How to get model with hasOne multiple times?

Question

Yii

There is a model $panel it has a function

public function getCar()
    {
        return $this->hasOne(Car::className(), ['id' => 'car_id']);
    }

car has:

public function getBrand()
  {
    return $this->hasOne(Brand::className(), [
      'id' => $this->brand_id
    ]);
  }

Accordingly, to get the $name attribute from $brand, I use the following code:
$model->car->brand->name
Displays an error:
Getting unknown property: app\models\Car::4

Answer 1

change

public function getBrand()
  {
    return $this->hasOne(Brand::className(), [
      'id' => $this->brand_id
    ]);
  }

on the

public function getBrand()
  {
    return $this->hasOne(Brand::className(), [
      'id' => 'brand_id'
    ]);
  }

since this is a link, you must specify the name of the column in the database, and not its value
