调用未定义的方法 App\Models\Car::setCreatedAt() - Laravel - 5.8.16

Posted 2023-03-14

【中文标题】调用未定义的方法 App\\Models\\Car::setCreatedAt() - Laravel - 5.8.16

【英文标题】：Call to undefined method App\Models\Car::setCreatedAt() - Laravel - 5.8.16调用未定义的方法 App\Models\Car::setCreatedAt() - Laravel - 5.8.16

【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？

【参考方案1】：

我只是重新安装Laravel。

删除vendor文件夹； 删除composer.lock； composer update 在控制台中。

感谢@Jonas Staudenmeir 的帮助。
