在"is_salable"上过滤产品集合； [英] filtering product collection on "is_salable"

问题描述

我想过滤产品集合以仅显示有库存的物品.我认为这很容易，因为有一个名为"is_salable"的属性(如果有库存)为1(真)，否则为0(假).但是，无论我做什么，都行不通.此外，它似乎在查询结束之前就停止了执行.

I would like to filter a product collection to show only items that are in stock. I thought this would be easy given that there's an attribute called 'is_salable' that is 1 (true) if it's in stock, 0 (false) if not. But no matter what I do, it doesn't work. Further, it seems to halt the execution of the query before it finishes.

以下是一些示例代码:

$this->_productCollection = Mage::getModel('catalog/product')->getCollection();
$this->_productCollection->addAttributeToSelect('*');
$this->_productCollection->addAttributeToFilter('my_attribute', true);
//So far, so good...filtering on 'my_attribute' works!
Mage::Log("select: " . $this->_productCollection->getSelect());
//Successfully outputs the SQL query
$this->_productCollection->addFieldToFilter('is_salable', '1');
Mage::Log("select: " . $this->_productCollection->getSelect());
//does NOT output any query...it's like it died trying

那么我在做什么错了?我已经尝试过'addFieldToFilter'，'addAttributeToFilter'和其他各种查询，例如:addFieldToFilter('is_salable', array('eq' => true))等...

So what am I doing wrong? I've tried 'addFieldToFilter', 'addAttributeToFilter', and miscellaneous other queries, such as: addFieldToFilter('is_salable', array('eq' => true)), etc...

有人知道该怎么做吗?如果"is_salable"不是答案，那么我所需要做的就是过滤出没有库存的产品...因此，任何可行的方法都可以:)

Anyone know how to do this? If 'is_salable' is not the answer, all I need to do is filter out products that are not in stock...so whatever works to do that would be fine :)

谢谢！

推荐答案

产品中没有is_salable属性，因此它将引发异常.如果只想显示有库存的产品，请使用此库存模型addInStockFilterToCollection方法:

There is no is_salable attribute in the product so it will rise an exception. If you want to display only products that are in stock, use this stock model addInStockFilterToCollection method:

Mage::getSingleton('cataloginventory/stock')->addInStockFilterToCollection($this->_productCollection);
