Yii2 - ActiveRecord到Array

Question

有没有办法ActiveRecord在Yii2中转换为数组？我知道我们可以做到这一点ActiveQuery,例如User::find()->asArray()->one();,但是Model当它已经被提取时我们可以转换为数组吗？我想在beforeSave()方法中执行该操作并将该数组存储在缓存中.

Answer 1

来自Yii2 指南 - 使用ArrayHelper::toArray():

$posts = Post::find()->limit(10)->all();
$data = ArrayHelper::toArray($posts, [
    'app\models\Post' => [
        'id',
        'title',
        // the key name in array result => property name
        'createTime' => 'created_at',
        // the key name in array result => anonymous function
        'length' => function ($post) {
            return strlen($post->content);
        },
    ],
]);

Answer 2

试试这个!

$model = Post::find($id)->limit(10)->asArray()->all();
$model = Post::find($id)->select('id,name as full')->asArray()->one();
$model = Post::find($id)->select('id,name as full')->asArray()->all();
$model = Post::find()->where(['slug'=>$slug])->asArray()->one();

对于一个模型来说，使用一个属性就足够了attributes

$User = User::find()->one();
$user_as_array = $User->attributes;
