Laravel Forge 部署失败，在用户模型上输入 php 7.4 属性

Question

我在 Laravel 7 中用 php 7.4 创建了新项目，在用户模型上我有这个属性：

* The attributes that are mass assignable.
     *
     * @var array
     */
    protected array $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected array $hidden = [
        'password', 'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected array $casts = [
        'email_verified_at' => 'datetime',
    ];

在 Laravel Homestead 上一切正常，但是当我想在 UserSeeder 上使用 Laravel Forge 部署应用程序时，我收到了这条消息：

PHP Fatal error:  Type of App\User::$casts must not be defined (as in class Illuminate\Foundation\Auth\User)

Answer 1

您收到此错误的原因是因为父项 class 中定义的 $casts 属性未键入为 array 属性但它在您的模型中。

根据 PHP RFC: Typed Properties 2.0:

Property types are invariant. This means that the type of a (non-private) property is not allowed to change during inheritance (this includes adding or removing property types).

为了解决这个问题，我建议简单地从您的继承属性中删除 array。

我还建议阅读 this article 以获取有关类型化属性和其他 PHP 7.4 更改的更多信息。
