在洋红色中从 EE 降级到 CE 时出错

Question

我正在按照 http://blog.yanted.com/2014/02/21/downgrading-magento-enterprise-to-community/中的步骤将magento从EE降级到CE，但我被困在"修复登录"。我已经完成了该步骤的所有操作，但我不确定是否修复了它。我现在的情况是我可以打开前端网站，但无法登录。在后端，我可以登录，但我无法打开"目录/管理产品"，"目录/管理类别"，"目录/URL重写管理"，返回以下错误（主要错误相同：指定了无效的后端模型：enterprise_targetrule/catalog_product_attribute_backend_rule，在"跟踪"之后，内容不同）：

处理您的请求时出错

Invalid backend model specified: enterprise_targetrule/catalog_product_attribute_backend_rule

有人知道我该如何解决这种情况吗？

Answer 1

这是因为有一组产品属性使用仅限企业的后端模型。我的建议是创建一个设置脚本，该脚本将删除所有这些属性。

您可以通过以下 sql 找到这些属性。

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

请注意，其中一些属性应

更新为使用正常的非企业模型，而某些属性应一起删除。
