問題描述

我正在研究 Magento 模塊，需要知道是否可以回滾一系列模型保存.基本上，我有五個模型加上我模塊中的幾個模型，我需要一個接一個地保存:

I'm working on a Magento module and need to know if it's possible to roll back a series of model saves. Basically, I have five models plus several from my module that I need to save one after the other:

admin/role
admin/user
core/website
core/store_group
core/store
mymodule/model1
mymodule/model2

我的問題是，每當這些模型中的任何一個拋出異常時，我都需要進入 MySQL 并手動刪除所有已保存的行.這是非常沒有成效的.

My problem is that whenever any of these models throw an exception, I need to go into MySQL and manually delete all the rows that were saved. This is very unproductive.

我很確定 Magento 沒有我可以在我的上下文中訪問的回滾過程.比如我查看了Mage_Core_Model_Abstract，在save方法中，回滾機制都是受保護的.

I'm pretty sure that Magento doesn't have a rollback procedure that I can access in my context. For example, I looked in Mage_Core_Model_Abstract and in the save method, the rollback mechanisms are all protected.

那么，我的問題是，在 Magento 中進行數據庫事務是否有一些我應該注意的最佳實踐?

So, my question is, is there some best practice for doing database transactions in Magento that I should be aware of?

推薦答案

我在核心代碼中看到了以下內容，看起來正是您訂購的.

I've seen the following used in core code, and it looks like its just what you ordered.

$transactionSave = Mage::getModel('core/resource_transaction');
$transactionSave->addObject($model_one)
$transactionSave->addObject($model_two)
$transactionSave->save();

core/resource_transaction 對象允許您添加 Magento 對象，并對它們執行批量保存.試一試，我很想在評論中聽到這對你有用或沒用.

The core/resource_transaction object allows you to add Magento objects, and perform a mass save on them. Give that a try, and I'd love to hear how this does, or doesn't, work for you in the comments.
