Thanks Dieter, But it makes no difference. I am guessing that perhaps the object that I am calling is not subclassed off something that it should be for the VHM to work. Does anybody know of a property or method that I should be looking for that absolute_url() might need to determine the correct Base?

Evan, it is a python product that I have built, it is subclassed on another abstract class I built and the simpleItem class. None of my classes redefine the absolute_url() method - or for that matter any related methods.

Chris, We start with a base class called GenericObject... class GenericObject(Implicit, Persistent, RoleManager, Item, PropertyManager, MessageListener): It contains, amongst others, the following method (the only one in the entire product that uses a aq_ method) #---------------------------------------------------------------# def getParent(self): "Return the parent container that this object is within" return self.aq_parent #---------------------------------------------------------------#

From there we create several other base classes and sub off them a few times.

The product presently has about 40 classes with about 8 base classes from which all others are built. To narrow it down for you a bit. There is a container called a Model and it contains Reports. and it is the reports that I am getting the URL of. To get the list of reports I use the following method of the model... #---------------------------------------------------------------# def getReports(self, type=None): """ Returns a sequence of the immediate child Report(s) in this container, sorted by title. If type is specified then the results are filtered. """ #get the immediate children of the container children = self.objectValues() #filter the Report(s) only reports = [x for x in children if x.isInstanceOf("Report")] if type != None: reports = [x for x in reports if x.getReportType() == type] #sort the report by Report.getTitle() reports.sort(lambda x, y : x.getTitle() < y.getTitle()) return reports #---------------------------------------------------------------# This returns a list and then i do the .absolute_url() on each of these. Could it be the way I get the reports?

Jens, => => make your life easier by having objectValues do the filtering for you:: => => children = self.objectValues(['Report']) => Thanks but this will not work for me. I have many different types of reports, all of which have different metatypes. I need to be able to determine which objects were built from what baseclasses. We also found the zope isInstanceOf() not to work all the time so we built our own, hence we use reports = [x for x in children if x.isInstanceOf("Report")] Thanks Tom

Chris, It is the same Item, but I removed Implicit, and Persistent, and found that I then lost Persistence and acquisition in my objects - lots of errors everywhere, so I had to put them back in. Also the addition of Traversable made no difference. Thanks anyway.

I agree with Chris that Traversable should be in there, otherwise you're going to pick it up through acquisition and get funky answers. You said it made no difference, though. Argh. Could you please give a concrete example of the URL that you're expecting and the one you're getting? Cheers, Evan @ 4-am

Is this intended behaviour or is this a bug?

I think you need to provide more info. Primarily, the contents of your access rule, but also the exception Type, Value and traceback that you recieved. cheers, Chris

Does anybody know of a property or method that I should be looking for that absolute_url() might need to determine the correct Base? Following the code of the standard "absolute_url" (to be found in "OFS/Traversable"):

def absolute_url(self, relative=0): try: req = self.REQUEST except AttributeError: req = {} rpp = req.get('VirtualRootPhysicalPath', ('',)) spp = self.getPhysicalPath() i = 0 for name in rpp[:len(spp)]: if spp[i] == name: i = i + 1 else: break path = map(quote, spp[i:]) if relative: # This is useful for physical path relative to a VirtualRoot return join(path, '/') return join([req['SERVER_URL']] + req._script + path, '/') As you see, there are several possible reasons why you may get the physical path: * your object is unable to acquire "REQUEST" (because it is not (yet) acquisition wrapped) * the 'VirtualRootPhysicalPath' in "REQUEST" is wrong (not very likely) * the SERVER_URL or "_script" in "REQUEST" are wrong (not very likely) * you happen to access a non-standard "absolute_url" (use, e.g. "DocFinder", to check that).
