目录价格规则适用于special_price

Question

关于stackoverflow的第一个问题......我很兴奋:)

目前,如果magento低于应用的目录价格规则,则使用特殊价格.如果目录定价规则使产品比特价便宜,则目录定价规则定义商店价格.

我正在寻找一种优雅的方法,使目录价格规则适用于特殊价格(另外).也许有一些商店配置呢？也许有一些整洁的观察者的方式？

非常感谢!

适用于当前的Magento 1.9.3.10.刚刚更新后在项目中测试了它.约瑟夫尝试了另一种可行的方法.

我很遗憾地说,我解决了我自己的第一个真正的stackoverflow问题:

1. 去 Mage_CatalogRule_Model_Resource_Rule
2. 转到方法 _getRuleProductsStmt

3. 将其添加到第一个原始之前的方法的初始选择中->from:

   $ select-> from(null,array('default_price'=> new Zend_Db_Expr("CASE WHEN pp_default_special.value THEN pp_default_special.value ELSE pp_default_normal.value END")));

4. 在第一次join()发生后添加它

   $specialPriceAttr  = Mage::getSingleton('eav/config')
                       ->getAttribute(Mage_Catalog_Model_Product::ENTITY, 'special_price');
   $specialPriceTable = $specialPriceAttr->getBackend()->getTable();
   $specialPriceAttributeId= $specialPriceAttr->getId();
   $joinCondition2 = '%1$s.entity_id=rp.product_id AND (%1$s.attribute_id=' . $specialPriceAttributeId . ') 
                                                   AND %1$s.store_id=%2$s';
   $select->join(
           array('pp_default_special'=>$specialPriceTable),
           sprintf($joinCondition2, 'pp_default_special', Mage_Core_Model_App::ADMIN_STORE_ID), null
   );
   

这个怎么运作:

应用目录定价规则(通过后端或cron)时,将catalogrule_product_price填充db表.上面的SQL魔法将special_price结果集作为列加入(如果存在)default_value,如果没有找到special_price则会加入常规价格.

结果已经过检查并且正在运行.

玩得开心!并且不要破解核心!

在较新的Magento版本中似乎有一些变化!对于1.9我必须:

复制app/code/core/Mage/CatalogRule/Model/Action/Index/Refresh.php到app/code/local/Mage/CatalogRule/Model/Action/Index/Refresh.php 更改_prepareTemporarySelect.

我在这里完整地发布了这个功能.添加了special_price的联接,然后将价格添加到价格字段的选择中.它仍然更喜欢团体价格,因为我从不使用它们,但这可以很容易地改变!
