Yii2多對多模型關係

我已經在兩個yii2模型之間實現了多對多的關係： slider，images，sliders_images其中sliders_images是結點表。每個模型都擴展了由Gii生成的基本模型，所以當我需要時我可以覆蓋基本模型而不會丟失個人方法。
Slider.php
Yii2多對多模型關係

... 
public function getImages(){ 
    return $this->hasMany(Images::className(), ['id' => 'image_id']) 
     ->viaTable('sliders_images', ['slider_id' => 'id']); 
} 
...

Images.php

... 
public function getSlider(){ 
    return $this->hasMany(Slider::className(), ['slider_id' => 'id']) 
     ->viaTable('sliders_images', ['image_id' => 'id']); 
} 
...

SlidersImages.php

... 
/** 
* @return \yii\db\ActiveQuery 
*/ 
public function getImage() 
{ 
    return $this->hasOne(Images::className(), ['id' => 'image_id']); 
} 

/** 
* @return \yii\db\ActiveQuery 
*/ 
public function getSlider() 
{ 
    return $this->hasOne(Slider::className(), ['id' => 'slider_id']); 
} 
...

當我使用的功能鏈接（）來popolate上創建結表滑塊一切正常，但當我嘗試從滑塊ActiveRecord對象獲取圖像時發生問題（Yii2 documentation）：

public function actionView($id) 
{ 
    $slider = $this->findModel($id); 
    return $this->render('view', [ 
     'model' => $slider, 
     'images' => $slider->images 
    ]); 
} 

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

如果我在視圖中調試$ images變量，它是空的並且不包含相關圖像。如何設置模型以獲得關係中的正確訪問權限？

編輯：
當我嘗試在slidersImage訪問得到juncyion表中的行：$slider->sliderImage做工精細，錯過在圖像行的訪問。

滑塊表

圖像表

節目表中數據 – Vitaly

@Vitaly一致我希望數據是可以理解的 – MarBer

'die（var_dump（$ slider-> images））;'？ null – Vitaly

這public $images;屬性應該改名，因爲它有關係的名字getImages()

class Slider extends Sl 
{ 
    const SCENARIO_CREATE = 'create'; 
    const SCENARIO_VIEW = 'view'; 
    const SCENARIO_UPDATE = 'update'; 

    public $images; // This should be renamed 
    ...
