錯誤在降級從EE到CE在magento

Question

我降級從EE到CE的步驟http://blog.yanted.com/2014/02/21/downgrading-magento-enterprise-to-community/中的步驟，我被卡在「修復登錄」。我已經完成了這一步，但我不確定我是否修復了它。我現在的情況是，我可以打開前端網站，但無法登錄。在後端，我可以登錄，但無法打開「目錄/管理產品」，「目錄/管理類別」，「目錄/ URL重寫管理」，以下錯誤返回（主要錯誤是一樣的：無效的後端模式指定：enterprise_targetrule/catalog_product_attribute_backend_rule後，‘跟蹤’，內容是不同的）：

出現了一個錯誤處理您的請求

Invalid backend model specified: enterprise_targetrule/catalog_product_attribute_backend_rule

任何人都知道我可以如何解決這種情況？

Answer 1

這是因爲有一組產品屬性使用僅企業後端模型。我的建議是創建一個設置腳本，去除所有這些屬性。

您可以通過以下sql找到這些屬性。

SELECT 
    * 
FROM 
    `eav_attribute` 
WHERE 
    attribute_model LIKE "%enterprise%" 
    OR backend_model LIKE "%enterprise%" 
    OR frontend_model LIKE "%enterprise%" 
    OR source_model LIKE "%enterprise%" 

請注意，這些屬性中的某些屬性應更新爲使用正常的非企業模型，而其中一些屬性應該一起刪除。
