Hi all

I have some code like these:

def __bobo_traverse__(self, REQUEST, name): obj = getattr(self, name, None) if obj is not None: return obj else: return 'cocohuaha'

But zope raise an The object at http://myserver:8080/TestingZope/Test is not publishable.

Why?

Thank you!

A good clue is to grep the zope source for that error message. If you do, you will find that strings (and most built-in python types) are not directly publishable. See for yourself in BaseRequest.traverse() in lib/python/ZPublisher/BaseRequest.py: # 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): return response.debugError( "The object at %s is not publishable." % URL ) ... itypes = {} for name in ('NoneType', 'IntType', 'LongType', 'FloatType', 'StringType', 'BufferType', 'TupleType', 'ListType', 'DictType', 'XRangeType', 'SliceType', 'EllipsisType', 'UnicodeType', 'CodeType', 'TracebackType', 'FrameType', 'DictProxyType'): if hasattr(types, name): itypes[getattr(types, name)] = 0 def typeCheck(obj, deny=itypes): # Return true if its ok to publish the type, false otherwise. return deny.get(type(obj), 1) -- Paul Winkler http://www.slinkp.com
