plone - 如何修复 zc.relation 目录中的 KeyError

Question

我们的一个网站有一个损坏的关系目录，我不知道如何修复它。

这是我在日志中看到的:

我已经尝试过 The dreaded plone.relations IntId KeyError 中的代码，由 @martijn-pieters 几年前编写，但似乎不再有效，因为我找不到任何名为 IComplexRelationshipContainer 的接口(interface)。

有什么提示吗？

• 验证是否安装了 plone.relations。

• 请参阅此处 http://davidjb.com/blog/2010/10/bad-relationships-relationchoice-relationcatalog-and-removed-dexterity-content-in-plone ，可能是这个问题的解决方案。

例如。

from zope.component.hooks import setSite
from AccessControl.SecurityManagement import newSecurityManager
from AccessControl.SecurityManager import setSecurityPolicy
from Testing.makerequest import makerequest
from Products.CMFCore.tests.base.security import PermissiveSecurityPolicy, OmnipotentUser
from zope.component import getUtility
from zope.intid.interfaces import IIntIds
from zc.relation.interfaces import ICatalog
_policy=PermissiveSecurityPolicy()
_oldpolicy=setSecurityPolicy(_policy)
newSecurityManager(None, OmnipotentUser().__of__(app.acl_users))

portal = makerequest(app['Plone'])
setSite(portal)

intids = getUtility(IIntIds)
catalog = getUtility(ICatalog)

print [x.from_object for x in sorted(catalog.findRelations({}))]
