如何在YII 2框架中調用模型的方法？

Question

我是YII框架中的新手。我已經正確安裝和創建使用Yii的GII擴展測試控制器&測試模型。我在Model中創建了一個方法，並想在Controller中訪問但無法訪問。

測試控制器

<?php 

namespace app\controllers\api; 

use Yii; 
use app\models\api\Test; 
use yii\web\Controller; 
use yii\web\NotFoundHttpException; 

class TestController extends \yii\web\Controller 
{ 
    public $modelClass = 'app\models\api\Test'; 
    private $model; 

    public function filters(){ 
      return array(
       'accessControl', // perform access control for CRUD operations 
       array(
        'RestfullYii.filters.ERestFilter + 
        REST.GET, REST.PUT, REST.POST, REST.DELETE, REST.OPTIONS' 
       ), 
      ); 
    } 
    public function actions(){ 
      return array(
       'REST.'=>'RestfullYii.actions.ERestActionProvider', 
      ); 
    } 
    public function accessRules(){ 
      return array(
       array('allow', 'actions'=>array('REST.GET', 'REST.PUT', 'REST.POST', 'REST.DELETE', 'REST.OPTIONS'), 
       'users'=>array('*'), 
       ), 
       array('deny', // deny all users 
        'users'=>array('*'), 
       ), 
      ); 
    } 


    protected function loadModel($id = null) 
    { 
     if($this->model===null) 
     { 
      if($id!==null) 
       $this->model=TestModel::model()->findByPk($id); 
     } 
     return $this->model; 
    } 

    public function actionIndex() 
    { 
     //return $this->render('index'); 
     //$array = $modelClass::model()->listUserData(); 
     //$array = Yii::app()->model()->listUserData(); 
     //$array = $modelClass->listUserData(); 
     // echo TestModel()->listUserData(); 
     print "<pre>";print_r($this->model->listUserData()); 
     exit; 
    } 

} 

測試模型

<?php 

namespace app\models\api; 

use Yii; 

/** 
* This is the model class for table "users". 
* 
* @property integer $id 
* @property string $username 
* @property string $password 
* @property string $email 
* @property string $activkey 
* @property integer $createtime 
* @property integer $lastvisit 
* @property integer $superuser 
* @property integer $status 
*/ 
class Test extends \yii\db\ActiveRecord 
{ 
    /** 
    * @inheritdoc 
    */ 
    public static function tableName() 
    { 
     return 'users'; 
    } 

    /** 
    * @inheritdoc 
    */ 
    public function rules() 
    { 
     return [ 
      [['username', 'password', 'email'], 'required'], 
      [['createtime', 'lastvisit', 'superuser', 'status'], 'integer'], 
      [['username'], 'string', 'max' => 50], 
      [['password', 'email', 'activkey'], 'string', 'max' => 128], 
      [['username'], 'unique'], 
      [['email'], 'unique'], 
     ]; 
    } 

    /** 
    * @inheritdoc 
    */ 
    public function attributeLabels() 
    { 
     return [ 
      'id' => 'ID', 
      'username' => 'Username', 
      'password' => 'Password', 
      'email' => 'Email', 
      'activkey' => 'Activkey', 
      'createtime' => 'Createtime', 
      'lastvisit' => 'Lastvisit', 
      'superuser' => 'Superuser', 
      'status' => 'Status', 
     ]; 
    } 
    public static function listUserData(){ 
      $UserData = Test::model()->findAll('status = "0"'); 
      return $UserData; 
     } 
} 

我嘗試在論壇搜索，但沒能解決，請你能幫助我解決？

在此先感謝。

Answer 1

其簡單的創建Model的instance，然後調用所需function

像

public function actionIndex() 
    { 
      $model = new Test(); 
      print "<pre>";print_r($model->listUserData()); 
     exit; 
    } 

試試這個

public static function listUserData(){ 

     $UserData = Test::findAll(['status' =>0]);//in Yii2 
     //$UserData = Test::model()->findByAttributes(array('status' => 0)); in yii 1.1 

      return $UserData;    
} 

Answer 2

在控制器中。

use pathtotestmodel/Test 

public function actionIndex() 
{ 
$model = new Test(); 
$userdata = $model->listUserData(); 
} 

OR

public function actionIndex() 
{ 
$userdata = Test::listUserData(); 
}
