推荐答案

1. 转到portal_purgepolicy并将数字设置为某个数字(我通常使用'3'至少保留一些历史记录.)

2. 运行以下脚本:

1. Go to portal_purgepolicy and set the number to some number (I usually use '3' to keep at least some history).

2. Run the following script:

from DateTime import DateTime
from Products.CMFCore.utils import getToolByName
from Products.CMFEditions.utilities import dereference


policy = getToolByName(self.context, 'portal_purgepolicy')
catalog = getToolByName(self.context, 'portal_catalog')

for count, brain in enumerate(catalog()):
    obj = brain.getObject()

    # only purge old content
    if obj.created() < (DateTime() - 30):
        obj, history_id = dereference(obj)
        policy.beforeSaveHook(history_id, obj)
        print 'purged object ' + obj.absolute_url_path()
