如果在我的重氮控制面板中 > '参数表达式' 我把

have_left_portlets = python:context and context.restrictedTraverse('@@plone').have_portlets('plone.leftcolumn',context)

仅当我在门户主页上时才会收到错误消息：

2012-06-26 16:51:42 ERROR plone.transformchain Unexpected error whilst trying to apply transform chain
Traceback (most recent call last):
  File "/Users/vito/.buildout/eggs/plone.transformchain-1.0.2-py2.6.egg/plone/transformchain/transformer.py", line 48, in __call__

    v = getattr(inst, name)
AttributeError: 'FilesystemResourceDirectory' object has no attribute 'restrictedTraverse'

我该如何解决这个问题？

我怀疑这是 plone.app.theming 中的一个错误：上下文设置不正确。不过很奇怪。

只需确认问题已存在：我得到了大约相同的回溯，站点本身看起来不错，但是对于站点内的每次点击，我都会在我的实例 fg 中得到以下回溯：

2012-08-10 15:05:05 ERROR plone.transformchain Unexpected error whilst trying to apply transform chain
Traceback (most recent call last):
  File "/opt/etc/buildout/eggs/plone.transformchain-1.0.2-py2.6.egg/plone/transformchain/transformer.py", line 48, in __call__

    return eval(self._code, vars, {})
  File "PythonExpr", line 1, in <expression>
AttributeError: 'FilesystemResourceDirectory' object has no attribute 'Language'

这是因为我的 manifest.cfg 中有以下行（与 plone_control_panel 中的参数行大致相同：

lang = python: context.Language()

在我的情况下，这在某种程度上是合乎逻辑的，因为并非所有内容对象都有一个名为 Language() 的索引。

但是在这种情况下，“上下文”显然是指“FileSystemResourceDirectory”，而不是您所在的内容？如果我能找到更多信息，我会尝试使用 pdb...
