Yii - Yii 获取超出范围的信息

Question

我在 Yii 中进行复杂的 AR 搜索时遇到问题，您能帮帮我吗？

我正在做这样的 AR 搜索：

$property = Properties::model()->with( $this->propertiesConditions($photoid, $languageApp, $value->propertyid) )->findAll('t.id = :id', array('id'=>$value->propertyid));

$this->propertiesConditions 是一个函数，它将返回一个包含搜索所需条件的数组（我不知道为什么它看起来没有正确的间距）。

public function propertiesConditions($photoid, $languageApp, $propertyid)
{
    if (!is_null($photoid)) {
        return array(
                'owner', 
                'amenities',
                'i18npropertiesinfos'=>array('condition'=>'i18npropertiesinfos.iso6391code="'.$languageApp.'"'),
                'rates'=>array('condition'=>'rates.propertyid="'.$propertyid.'"', 'order'=>'price'),
                'images'=>array('condition'=>'images.id="'.$photoid.'"'),
                );
    }else{
        return array(
                'owner', 
                'amenities',
                'i18npropertiesinfos'=>array('condition'=>'i18npropertiesinfos.iso6391code="'.$languageApp.'"'),
                'rates'=>array('condition'=>'rates.propertyid="'.$propertyid.'"', 'order'=>'price'),
                );
    }
}

由于某种原因，如果属性没有 $photoid ($photoid == null)，它会查找正确的数组（没有“图像”的数组），但是当我将它发送到视图并 var 转储属性我得到没有'images'属性的对象（这很好），但是当我 var_dump($property->images) 我得到一个图像模型（我不知道它从哪里得到它）

谢谢。

在您的查找方法中，您选择了Properties 列表而没有images 关系，这并不意味着所有属性记录都与图像没有任何关系。如果其中一些与其他图像记录有关系，则此行$property->images 仍然可以工作。

我不确定您的意思是什么，但是如果您打算仅将两个案例分开关于是否有图像的属性列表，您可以在没有“图像”的情况下在属性模型中添加更多条件. 示例：

'notHasImages' => array(self::HAS_ONE, 'Images', array('id'=>'product_id'),
                        'condition'=>'images.product_id IS NULL'),

（假设product_id是Images表属性的外键）（ONE to MANY）
