Question

我们的某个网站的关系目录已经破损，我不知道如何修复它。

这就是我在日志中看到的内容：

我已经尝试了几年前由@ martijn-pieters编写的The dreaded plone.relations IntId KeyError中的代码，但似乎不再有效，因为我无法找到任何名为IComplexRelationshipContainer的接口。

任何提示？

Answer 1

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，可能是此问题的解决方案。

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({}))]

Answer 2

我想几年前我对类似的东西很不满意。

我发布了这个，一切都运行良好：

    from Products.Five.browser import BrowserView
    from Products.CMFCore.utils import getToolByName
    from z3c.relationfield.event import updateRelations
    from z3c.relationfield.interfaces import IHasRelations
    from zc.relation.interfaces import ICatalog
    from zope.component import getUtility


    class View(BrowserView):
        def __call__(self):
            rcatalog = getUtility(ICatalog)
            # Clear the relation catalog to fix issues with interfaces that don't exist anymore.
            # This actually fixes the from_interfaces_flattened and to_interfaces_flattened indexes.
            rcatalog.clear()

            pc = getToolByName(self.context, 'portal_catalog')
            brains = pc.searchResults(object_provides=IHasRelations.__identifier__)
            for brain in brains:
                obj = brain.getObject()
                updateRelations(obj, None)
            return "Catalog rebuilt for %s objects" % len(brains)
