运行transmogrifier管道并创建新对象时，在创建某些内容类型（例如“文档”-
它在plone.app.transmogrifier.atschemaupdater.py
在此通话中：event.notify(ObjectInitializedEvent(obj))
这非常烦人，因为控制台上没有堆栈跟踪。也很难
进行调试，因为内部有很多Plone和Zope调用在执行动态功能
“订阅事件”。到目前为止，我通过PDB获得了这个stacktrace：

到目前为止，我的解决方法是将zope.event.notify修改为no-op
在运行管道之前，但这显然不是这样做的方法。
值得注意的是：我使用视图代码中的函数触发了transmogrifier管道-（当然，我确实以站点管理员的身份加载视图）。
最佳答案
在运行transmogrifier管道时，应禁用版本控制。这是plone.app.transmogrifier文档中的documented； plone.app.transmogrifier.versioning蓝图提供了一个简单的插入式配方，用于切换此设置：
[transmogrifier]
pipeline =
schemasource
disable_versioning
constructor
enable_versioning
schemaupdater
[disable_versioning]
blueprint = plone.app.transmogrifier.versioning.disable
[constructor]
blueprint = collective.transmogrifier.sections.constructor
[enable_versioning]
blueprint = plone.app.transmogrifier.versioning.enable
关于python - 使用Transmogrifier在Plone中上载内容时发生未经授权的异常，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/13995273/
