Plone 4.3迁移 - AttributeError：类型对象'IIntIds'没有属性'__iro__'

Question

将Plone 4.1 +敏捷站点迁移到Plone 4.3后，站点的/ manage_workspace变得无法访问。数据库迁移无法执行。

仍然可以访问ZMI根目录。

AttributeError: type object 'IIntIds' has no attribute '__iro__' 

还有@@plone-upgrade无法访问。

任何想法或特殊迁移需要？

Answer 1

在敏捷2中，缺省情况下不再安装关系字段支持（其中包括安装intids目录）。为了得到它，你需要安装使用[关系]敏捷额外的：

[instance] 
eggs = 
    plone.app.dexterity [relations] 

这是在http://plone.org/documentation/manual/upgrade-guide/version/upgrading-plone-4.2-to-4.3/dexterity-optional-extras并在敏捷发行说明文件。
