php - Yii Framework 2.0 -findModel 返回一个空对象

Question

我正在尝试显示我存储在数据库中的表单值。但它没有发生并且还返回空值。我已经添加了我所做的一切。

Controller

protected function findModel($id)
    {
        if (($model = UserRegistration::find($id)->one()) !== null) {
            return $model;
        } else {
            throw new NotFoundHttpException('The requested page does not exist.');
        }
    }

型号

这是我的模型。我已将所有变量声明为公共(public)变量。这有问题吗？如果我删除我也会收到错误消息。

class UserRegistration extends ActiveRecord
{
    public $username;
    public $firstname;
    public $lastname;
    public $email;
    public $Country;
    public $State;
    public $City;
    public $phone_number;
    public $about_me;
    public $password;
    public $verify_password;    
    public $photo;

    public static function tableName()
    {
        return 'user';
    }

    public function rules()
    {
        return [
            [['username','password', 'email'], 'required'],
            [['status', 'created_at', 'updated_at', 'teespring_id'], 'integer'],
            [['username','lastname','firstname', 'password_hash', 'password_reset_token', 'email','about_me'], 'string', 'max' => 255],
            [['auth_key'], 'string', 'max' => 32],
            [['role'], 'string', 'max' => 10],
            [['email','username'],'email'],
            [['email','username','password_reset_token'], 'unique'],
            ['phone_number','string','length'=>10],
            [['Country','State','City'],'string'],
            ['verify_password','compare','compareAttribute'=>'password'],
            [['photo'],'file', 'extensions' => 'png, jpg']
        ];
    }
}

更新:我也尝试过 $model = UserRegistration::findOne($id)。但运气不好请帮助我。

它是 UserRegistration::findOne($id) 并且您不能声明来自数据库的属性，因为它们将为空。
