【问题描述】：
我正在使用最新的 Laravel。我有一个模型Car - id | name | * timestamp columns:
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class Car extends Model{
protected $fillable = [
'name'
];
}
汽车迁移：
public function up()
{
Schema::create('cars', function (Blueprint $table) {
$table->bigIncrements('id');
$table->integer('name')->nullable();
$table->timestamps();
});
我正在尝试在控制器的cars 表中保存新行：
$car = new Car();
$car->name = 'example';
$car->save();
，但对于 $car->save()，我收到此错误：
调用未定义的方法 App\Models\Car::setCreatedAt()
即使，如果我创建新的迁移/模型create_table_test（具有相同列的表），我也会遇到同样的错误。

【问题讨论】：
-
请发布堆栈跟踪。这是整个
Car模型吗？ -
谢谢，我已经更新了问题。是的，这都是关于模型
Car。 -
你使用的是什么版本的 Laravel？堆栈跟踪与
laravel-5.2标记不匹配。 -
Laravel:
5.8.16 -
看看
vendor/laravel/framework/src/Illuminate/Database/Eloquent/Concerns/HasTimestamps.php：有没有setCreatedAt()方法？
