摆脱 Plone4Artists 日历 - 从 Plone 3.3.5 迁移到 Plone 4.0.7
我正在尝试从 Plone 3.3.5 站点删除 P4Artists Calendar，以将其升级到 Plone 4.0.7。
我运行了一个脚本来删除所有对象的所有接口，具体来说：
'p4a.subtyper.interfaces.ISubtyped', 'p4a.calendar.interfaces.ICalendarEnhanced', 'p4a.calendar.interfaces.IPossibleCalendar', 'p4a.calendar.interfaces.ICalendarConfig', 'p4a.calendar.interfaces.IEventProvider', 'p4a.calendar.interfaces.IEvent', 'p4a.calendar.interfaces.IBasicCalendarSupport', 'p4a.calendar.interfaces.ICalendarSupport'
我正在使用的脚本使用 zope.interfaces.noLongerProvides 来摆脱对象。首先，我进行目录搜索并找到具有接口的对象，然后 noLongerProvides(object, interface)。
完成此操作后，我可以删除除“p4a.calendar.interfaces.IPossibleCalendar”之外的所有接口。该界面似乎适用于站点上的所有文件夹和集合，当尝试删除它们时，我遇到了异常。有谁了解这个界面的更多信息以及摆脱它的正确方法是什么？
编辑：
这是我的脚本生成的错误消息：
Exception at removeinterfaces for interface p4a.calendar.interfaces.IPossibleCalendar
Exception type: exceptions.ValueError
Exception value: Can only remove directly provided interfaces.
Exception traceback (starting next line):
File "remove-p4a.py", line 53, in removeinterfaces
noLongerProvides(obj, interface)
File "d:\plone-3.3.5-teste-20110927\zope2\lib\python\zope\interface\declarations.py",line 969, in noLongerProvides
raise ValueError("Can only remove directly provided interfaces.")
I am trying to remove P4Artists Calendar from a Plone 3.3.5 site, to upgrade it to Plone 4.0.7.
I ran a script to remove all interfaces from all objects, specifically:
'p4a.subtyper.interfaces.ISubtyped', 'p4a.calendar.interfaces.ICalendarEnhanced', 'p4a.calendar.interfaces.IPossibleCalendar', 'p4a.calendar.interfaces.ICalendarConfig', 'p4a.calendar.interfaces.IEventProvider', 'p4a.calendar.interfaces.IEvent', 'p4a.calendar.interfaces.IBasicCalendarSupport', 'p4a.calendar.interfaces.ICalendarSupport'
The script I am using uses zope.interfaces.noLongerProvides to get the objects rid of them. First, I do a catalog search and find the objects with the interface, and then noLongerProvides(object, interface).
After doing that, I am able to remove all of them interfaces, except for 'p4a.calendar.interfaces.IPossibleCalendar'. This interface seems to be applied to all of the Folders and Collections at the site, and when trying to remove them, I get an exception. Does anyone know more of this interface and what is the correct way of getting rid of it?
EDIT:
Here are the error messages generated by my script:
Exception at removeinterfaces for interface p4a.calendar.interfaces.IPossibleCalendar
Exception type: exceptions.ValueError
Exception value: Can only remove directly provided interfaces.

这些似乎是仅在通过 zcml 启动时应用的接口。因此，删除它们的唯一方法就是从您的设置中删除该产品。

These seem to be interfaces that are only applied on startup via zcml. So the only way to remove them is to remove the product from your setup.
