如何在YII2 ActiveController中按降序返回数据？请帮我。从activecontroller返回的JSON响应必须由news_id按降序排列。

 <?php
    namespace app\api\modules\v1\controllers;
    use yii\web\Response;
    use yii\rest\ActiveController;

    class NewsController extends ActiveController {
      // We are using the regular web app modules:
      public $modelClass = 'app\models\News';
    }

这是新闻模式

 <?php

    namespace app\models;

    use Yii;
    class News extends \yii\db\ActiveRecord
    {

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


        public function rules()
        {
            return [
                [['news_title', 'news_description', 'news_link'], 'required'],
                [['news_description', 'news_link'], 'string'],
                [['news_time'], 'safe'],
                [['news_title'], 'string', 'max' => 255],
            ];
        }


        public function attributeLabels()
        {
            return [
                'news_id' => 'News ID',
                'news_title' => 'News Title',
                'news_description' => 'News Description',
                'news_link' => 'News Link',
                'news_time' => 'News Time',
            ];
        }
    }

Answer 1

尝试使用http query发送订单在你的情况下，它将是： api/web/v1/news?sort=-news_id

Answer 2

试试这个：

<?php $data = News::find()->orderBy('news_id DESC')->all()  ?>
