[英]Magento resource model filter and limit
嗨,当使用Mage :: getResourceModel在magent中获取资源模型时,我可以添加过滤器没有问题,但是如何将结果集限制为5或10?
Assuming you're talking about Magento Collections, the ORM uses a paging style interface to limit things. 假设您在谈论Magento集合,那么ORM使用分页样式界面来限制事物。 You tell the collection how big you want each page to be (
setPageSize
), then you tell it which page you want to be on ( setCurPage
). 您告诉集合您希望每个页面多大(
setPageSize
),然后告诉它要放在哪个页面上( setCurPage
)。
//same as, and "better" than Mage:getResourceModel('catalog/product_collection');
Mage::getModel('catalog/product')
->getCollection()
->setPageSize(10)->setCurPage(1); //first 10 items
Mage::getModel('catalog/product')
->getCollection()
->setPageSize(10)->setCurPage(2); //second 10 items
///etc...
$select->limit(5)
检查app/core/mage/Catalog/Model/Resource/Eav/Mysql4/Url.php
的_getProducts()
方法(第806行)
