Laravel 当模型有构造函数时工厂失败

Question

在 Laravel 8 中，当我运行在具有 __construct 的模型上创建工厂 ()->create() 时，此代码：

Route::get('/test', function (){
    $doc = ClientDocument::factory()->create();
});

失败：

"SQLSTATE[HY000]: General error: 1364 Field 'filename' doesn't have a default value (SQL: insert into `client_documents` (`updated_at`, `created_at`) values (2021-11-16 12:45:20, 2021-11-16 12:45:20))"

如果我删除 __construct，工厂运行没问题并保存到数据库中...我在这里缺少什么？谢谢！

型号

class ClientDocument extends Model
{
    use HasFactory;

    protected $connection = 'mysql';

    protected $fillable = ['filename'];
    protected $locale;

    public function __construct() {
        // SET THE LANGUAGE
        if ( auth()->user() ) {
             $this->locale = auth()->user()->locale;
        } else {
             $this->locale = 'en';
        }
    }
}

工厂

class ClientDocumentFactory extends Factory
{
    public function definition()
    {
        $user = User::factory()->create();
        $client = $user->createNewClientFile();

        return [
            'filename'  => $this->faker->lexify('????????'),
        ];
    }
}

迁移

class CreateClientDocumentsTable extends Migration
{
    public function up()
    {
        Schema::create('client_documents', function (Blueprint $table) {
            $table->id();
            $table->string('filename');
            $table->timestamps();
        });

    }

    public function down()
    {
        Schema::dropIfExists('client_documents');
    }
}

Answer 1

为了结束这个问题，我把 Brian Thompson 的答案写在评论中：

"这不仅仅是调用父构造函数。基础模型 class 具有 public 函数 __construct(array $attributes = []) 的构造函数签名，因此您应该使您的构造函数与该签名兼容，并将可选的 $attributes 传递给父级

基本上，我只是将构造函数代码更改为：

public function __construct(array $attributes = []) {
    parent::__construct($attributes);
}
