Question

我在Yii遇到复杂的AR搜索问题，你能帮帮我吗？

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));

其中$this->propertiesConditions是一个函数，它将返回一个数组，其中包含搜索所需的条件（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，如果该属性没有$ photoid（$ photoid == null），它会查找正确的数组（没有'images'的数组）但是当我将它发送到视图并且var转储时属性我得到的对象没有'images'属性（这很好），但是当我var_dump（$ property-＆gt; images）我得到一个图像模型（我不知道它在哪里得到它）

感谢。

在find方法中，您选择Properties没有images关系的列表，但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仍可以正常工作。

我不确定你的观点是什么，但是如果你打算将两个案例分开，只讨论属性列表是否有图像，你可以在属性模型中添加更多条件，以防没有'图像' 。例如：

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

（假设product_id是Images表上的属性的外键）（ONE到MANY）
