Yii ActiveRecord 不填充父对象

Question

我正在尝试通过属性获取活动记录。

$user = self::find()->where(["username" => $username])->one();

当我检查方法 one() 时，我发现 BaseActiveRecord::populateRecord($record, $row) 从数据库中获取行。

正如您在图片上看到的那样，该行已检索到，但由于某种原因，我的对象尚未填充。

我尝试为字段添加设置器，结果是一样的。

有人可以帮我解决这个问题吗？

我检查了 BaseActiveRecord class:

public static function populateRecord($record, $row)
{
    $columns = array_flip($record->attributes());
    foreach ($row as $name => $value) {
        if (isset($columns[$name])) {
            $record->_attributes[$name] = $value;
        } elseif ($record->canSetProperty($name)) {
            $record->$name = $value;
        }
    }
    $record->_oldAttributes = $record->_attributes;
    $record->_related = [];
    $record->_relationsDependencies = [];
}

当然，$columns[$name]已经设置好了。

这是我的整个 ActiveRecord class:

<?php

use yii\base\Exception;

        $user = self::find()->where(["accessToken" => $token])->one();
        if ($user) {
            return null;
        }
        return new static($user);
    }

    public static function findByUsername($username): ?Admin

        $user = self::find()->where(["username" => $username])->one();
        if ($user) {

    public function beforeSave($insert): bool
    {
        if (parent::beforeSave($insert)) {
            if ($this->isNewRecord) {
                $this->auth_key = Yii::$app->security->generateRandomString();
            }
            return true;
        }
        return false;
    }

    public function getAccessToken(): string

    public function getId(): int

    }

    public function getAuthKey(): ?string
    {
        return $this->auth_key;
    }
}

ActiveRecord 将属性存储在私有属性 $_attributes and exposes them as virtual properties via __get() and __set(). It works as long as you don't define real property with that name (which you did). In that case you either need to remove these properties (for example public string $username = '';), or use getAttribute() 中以获取属性值（不太方便）：

$username = $user->getAttribute('username');
