Question

我正在尝试删除我正在测试的Plone网站。但是，当我删除它时，我收到错误。

从控制台：

ComponentLookupError: (<InterfaceClass zope.intid.interfaces.IIntIds>, '')

页面只显示：

 (<InterfaceClass zope.intid.interfaces.IIntIds>, '')

我确实在事件订阅者中使用了IIntIds，我想知道这可能是问题所在。

当特定内容类型的对象转换时，将创建另一个内容类型的另一个对象，并使用IIntIds实用程序从创建的对象“获取”关系值。 RelationValue附加到对象转换的relatedItems。创建的对象也有relatedItems，我得到对象转换的关系值，并将其附加到创建对象的relatedItems。

在configure.zcml中：

  <subscriber
  for="my.product.myobject.MyObject          
       Products.DCWorkflow.interfaces.IAfterTransitionEvent" 
  handler=".events.myObjectTransitioned" />

在events.py中：

def myObjectTransitioned(obj,event):

    ....
    action = event.status['complete']
    if action == 'activate':
        .....
        try:
            new_obj = api.content.create(container=OtherObjs,portal_type='my.object.anotherobject',
               title=a_concat_title, id=a_concat_title)
            int_ids = getUtility(IIntIds)

            obj.relatedItems.append(RelationValue(int_ids.getId(new_obj)))
            new_obj.relatedItems.append(RelationValue(int_ids.getId(obj)))

            obj.reindexObject()
            new_obj.reindexObject()
        except:
            print "failed creation"

我遇到了一个类似的问题，其中一个答案提到没有安装plone.app.relationfield或plone.app.intId。我有plone.app.relationfield（RelationValue）和plone.app.intId（plone.app.intid：install utility）。

我基本上这样做，以便new_obj可以通过方便地调用to_object从obj（转换对象）获取信息，反之亦然。但是，我猜这是导致这个错误，我应该使用back_obj的后向引用从obj获取信息？

基本上阻止您删除站点的是每次触发的事件（运行您提到的麻烦代码）。为防止出现这种情况，我建议您执行以下操作：

$ cd {buildout-dir}
$ bin/zopepy
> from transaction import commit
> app._delObject('Plone', suppress_events=True)
> commit()

一般情况下，不建议对Plone站点内的对象执行此操作，因为这样可以防止portal_catalog更新并导致其他副作用。但是当你整体删除网站时，没关系。

Plone- ComponentLookUpError阻止我删除Plone网站？
