Question

我能做到：app.restrictedTraverse('/zport/dmd/version')给了我'Zenoss 4.2.4'，但是当我在浏览器中执行相同操作时，它会给我

网站错误。发布此资源时遇到错误。请求的资源不存在。

对于dmd对象上的某些其他值或函数，它可以正常工作。如何调试“不存在”错误，以及如何在Zope中从url到对象的映射工作？

Citing the ZPublisher.BaseRequest.DefaultPublishTraverse.publishTraverse：

    # Ensure that the object has a docstring, or that the parent
    # object has a pseudo-docstring for the object. Objects that
    # have an empty or missing docstring are not published.
    doc = getattr(subobject, '__doc__', None)
    if not doc:
        raise Forbidden(
            "The object at %s has an empty or missing " \
            "docstring. Objects must have a docstring to be " \
            "published." % URL
            )

    # Hack for security: in Python 2.2.2, most built-in types
    # gained docstrings that they didn't have before. That caused
    # certain mutable types (dicts, lists) to become publishable
    # when they shouldn't be. The following check makes sure that
    # the right thing happens in both 2.2.2+ and earlier versions.

    if not typeCheck(subobject):
        raise Forbidden(
            "The object at %s is not publishable." % URL
            )

typeCheck认为这种类型是禁止的：

        ('NoneType', 'IntType', 'LongType', 'FloatType', 'StringType',
         'BufferType', 'TupleType', 'ListType', 'DictType', 'XRangeType',
         'SliceType', 'EllipsisType', 'UnicodeType', 'CodeType',
         'TracebackType', 'FrameType', 'DictProxyType', 'BooleanType',
         'ComplexType')

Zope发布的对象属性是什么？
