mysql - Magento AND/OR 组合模型过滤器

Question

您好，您在 Magento 中创建了一个自定义模型(资源基于 Mage_Core_Model_Resource_Db_Collection_Abstract )。一切都很好。 我尝试对表进行筛选，这将输出以下 where 子句:

where
  product_id = 1
  and ((customer_id = 0 and customergroup_id = 2) or (customergroup_id = 0 and customer_id = 3))
  and ((productgroup_id = 0 and product_class = 8) or (product_class = 0 and productgroup_id = 4))

关于如何使用 addFilter 或其他东西做到这一点有什么想法吗？

Answer 1

addFieldToFilter/addAttributeToFilter 方法不太适合复杂的查询。您将必须手动构建查询:

$collection->getSelect()
    ->where('product_id = ?', 1)
    ->where(sprintf(
        '((customer_id = %d AND customergroup_id = %d) OR (customer_id = %d AND customergroup_id = %d))',
        0, 2, 3, 0))
    ->where(sprintf(
        '((productgroup_id = %d AND product_class = %d) OR (productgroup_id = %d AND product_class = %d))',
        0, 8, 4, 0));
