Question

从plone 3.3.2到plone 4.2.1的迁移因PosKeyError而失败。我试过这篇文章中的食谱http://plonechix.blogspot.com/2009/12/definitive-guide-to-poskeyerror.html。我运行了error_finder片段，但它没有给我任何例外。我也尝试使用app.mysite._p_jar[p64(oid)]在调试器中获取对象 - 也没有成功，它失败并出现相同的错误。

如何删除损坏的对象或至少获取有关对象的更多信息（例如其类名或位置）？

完整追溯：

我相信这是same issue I just ran into如果回滚保存点，包括向目录添加对象，就会发生这种情况。我认为这是ZODB中的一个错误，但你可以通过解决任何回滚保存点来解决它，在这种情况下，这是将文件和图像迁移到blob。因此，如果您修复了使这些文件或图像成功迁移到BLOB（或者只是删除它们）的原因，那么它应该会成功。

迁移期间的POSKeyError
