Yes, the items come out of a Specialist. However, upgrading to 2.3.1b1 did not solve the problem.

So I changed getObject to wrap the try/except around only the restrictedTraverse call and moved the call to resovle_url outside that, and that seems to have fixed the problem. Thanks, Steve!

If this is what I think it is, it is fixed in the latest 2.3, as I submitted the patch that fixed it :-) Are your objects traversed to through an object that does __bobo_traverse__ -- like a ZPatterns Specialist, for example? If so, that's your problem. It's a combination of ZClasses not having a __roles__ attribute, and some security context being lost when going through a __bobo_traverse__. The patch to ZCatalog brains makes it fall back on resolve_url, which works just fine. -- Steve Alexander Software Engineer Cat-Box limited http://www.cat-box.net ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

It turns out that getObject has one of those nasty unadorned try: except: structures in it. It was masking an authorization error. The auth error is occuring in urestrictedTraverse, and the last lines of my traceback are: File /usr/local/zope/Zope230/lib/python/OFS/Traversable.py, line 190, in unrestr ictedTraverse (Object: ApplicationDefaultPermissions) Unauthorized: 0060175400 0060175400 is the ID of the first object returned by the catalog.

I forgot to look for the mybrains definition . Howevever, I'm still getting 'None' as the result. If I print out, say, catent.id, I see the correct ID for the object I'm trying to retrieve. It doesn't make sense that this is failing. I must be doing something stupid but I still can't see it. I tried calling getObject both with and without REQUEST as a parameter, with the same result. I guess it's time for some more source spelunking. --RDM ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )

Did you try updating the Catalog? Also, what happens if just append catent. Do you get something other than None then? I would assume so, but it might help to see exactly what the meta data is to identify the objects it "should" return. I agree that getobject should be a method of the result item, although implementing it might be a bit tricky to do. I looked into that a while back.

[Zope-dev] Calling Catalog from python script
I'll probably figure this out as soon as I post like last time, but I've been staring at it and can't see my mistake. The following code returns a list of None's: objs = [] for catent in container.Catalog(context.REQUEST): objs.append(container.Catalog.getobject(catent.data_record_id_)) return objs I've checked, and catent is a mybrains instance and catent.data_record_id_ has an increasing number as its value. So why doesn't this work? Also, and this is a better reason for posting this to zope-dev than asking for help is : why can't I say catent.getobject() That would seem to be a lot more OOish.
