我需要所有的发现(管理区域除外)来仅检索带有图像的产品。
在PhotoSmall
简单的情况下,我可以PhotoSmall.id IS NOT NULL
在一个条件下执行,因为 CakePhp 生成一个左连接,但我找不到至少需要的方法,PhotoBig
因为 CakePhp 执行两个查询来返回其结果。
要求如下,我只能显示具有一个PhotoSmall
和至少一个PhotoBig
系统范围的产品(站点的管理部分除外),该解决方案应与 CakePhp 分页一起使用
我尝试了以下代码但没有成功,它只返回产品数据,而不是照片数据:
$this->Product->recursive = -1;
$conditions = array('Product.category_id'=> $cats);
$joins = array(
array('table' => 'photos',
'alias' => 'PhotoBig',
'type' => 'INNER',
'conditions' => array(
'Product.id = PhotoBig.product_id',
)
),
array('table' => 'photos',
'alias' => 'PhotoSmall',
'type' => 'INNER',
'conditions' => array(
'Product.id = PhotoBig.product_id',
)
)
);
$this->paginate = array(
'limit' => 12,
'conditions' => $conditions,
'joins' => $joins,
);
