What does Access Content Info. mean for folders?
by Daniel Dekany 16 May '05

16 May '05

Maybe I'm just lame, but I can't find a description of the commonly used Zope permission anywhere. (Isn't it missing from the "Users and Security" chapter of the Zope book? How I am supposed to manage the site security if I know everything but the meaning of the concrete permissions?) Mostly, I would like to *know* (as opposed to try-and-guess) what does "Access contents information" mean. The definitions I have found on the Net was rather foggy. I guess because the meaning of this permission depends on the object in question... but is there a summary for the most commonly used objects at least? Especially, what does it mean for folders? At the first glance it specifies if I can get a contained object, but then I have found that somehow it doesn't apply to the contained objects that are folders, because I can always get those. Is this the rule? -- Best regards, Daniel Dekany

Corrupt Data.fs / ZODB
by Michael Kaplan 16 May '05

16 May '05

Sorry, I already wrote nearly the same mail in April but nobody answered. Since I cannot believe that there is no simple and well known solution for this problem - which probably affects many zope users - I try the same posting again. Any help is welcome but it should not be an option to erase the last 3 months of work and to return to the state before the mistake. ____________________ original posting _________________________________ I just found out that my Data.fs is corrupt. Zope is still running, and restarting but I'm getting POSKeyErrors if I want to see folder contents and in many other situations. I tried to follow the advice in http://www.zopelabs.com/cookbook/1095965033 (I use Zope-2.7.4) but end up with the 5th item there which says !! !! 5. Get at the Zope path for the container of the object that's throwing the POSKeyError: !! !! >>> obj=root.unrestrictedTraverse('/path/to/container') When I try this I get >>> obj=root.unrestrictedTraverse('/folder') Traceback (most recent call last): File "<stdin>", line 1, in ? NameError: name 'root' is not defined what's wrong here? I don't know what the author of this text means with '/path/to/container' and what I have to put there for 'root'. Therefore I used fsrefs.py and got information like oid 0x030571 Products.CMFCore.ActionInformation.ActionInformation last updated: 2005-03-14 08:20:34.643177, tid=0x35BE85493CF9666L refers to invalid object: oid 0x0304fa object creation was undone: 'Products.CMFCore.Expression.Expression' For this oid I get > python Python 2.4 (#1, Jan 14 2005, 00:24:33) [GCC 2.95.3 20010315 (release)] on sunos5 Type "help", "copyright", "credits" or "license" for more information. >>> from Zope.Startup.run import configure;configure('/etc/zope.conf') >>> from Zope import app >>> from ZODB.utils import p64 >>> from ZODB import POSException >>> app = app() >>> obj = app._p_jar[p64(0x030571)] >>> print obj.getId() view >>> print obj.bobobase_modification_time() 2005/03/14 09:20:34.643 GMT+1 >>> print obj.meta_type simple item >>> print obj.__ac_local_roles__ None Could anybody tell me, how I can delete this object from Data.fs? Will obj.manage_delObjects(id) do the job for me? What parameters do I have to give to the programm? Thanks a lot in advance Michael

assertion error
by Denis Mishunoff 15 May '05

15 May '05

Hello, Zope community. I use Zope 2.7.3, Python 2.3.4 and Plone 2.0.5 I have a strange behavior of template. It displays OK when accessing via IP address, but when I try to access it via name I get assertion error. Template uses the script that contains assertion: ... if brain.Title != '': obj = brain.getObject() # here it is assert(obj) type = obj.getAdvert_type() hereTitle = brain.Title ... As you can guess, variable "brain" contains brain from catalog. So, when I access the template, using this script via name it raises Assertion Error. Seems like it can't get object from catalog. But it works with IP... Please advise what is my problem. Thank you. -- Best regards, Denis Mishunoff mailto:spliter@sdtcom.lg.ua http://plonetarium.objectis.net

dollars-and-cents display fails
by Greg Fischer 15 May '05

15 May '05

Hi all, I just moved my zope app from 2.7.3 to 2.7.6, plus the mysql db from 5.0.0 to 5.0.4. After moving everything, I noticed all of my decimal fields that will no longer display their values in DTML unless I remove the dollars-and-cents fmt option. I tried all kinds of things in mysql thinking that was it because I knew there have been some major changes in that, but I couldnt find anything there. I tested a query from the mysql connection test, and it retrieves the values fine. Then I noticed, if I remove the fmt="dollars-and-cents", it would work. Any thoughts on why this is? Is it a security option on the folder or other items? I could just remove all the formatting, but I'd rather not. Thanks for any help! -- Greg Fischer 1st Byte Solutions http://www.1stbyte.com

Re: [Zope] URL rewriting (VHM and browser Id manager)
by Victor Kolisinski 14 May '05

14 May '05

Dear Dieter I am relativy new in the Zope community , so my firt goal was to check am I doing something wrong in Zope setup or in my code. Regarding debuging , I am also using the pdb debuging tool and for me it's works well. I don't have enough time for now to correct bugs in Zope but this bug is also related to bug "BASE Tag is generated without session information" described at http://www.zope.org/Collectors/Zope/885. Both bugs are related to session machinery without cookies , so in my case I can't using session data at all. Also my suggestion to Zope developers is that "Browser ID manager" should rewrite URL only if cookies are disabled on client side. Thank very much for your effort. --- Dieter Maurer <dieter(a)handshake.de> wrote: > Victor Kolisinski wrote at 2005-5-13 10:31 -0700: > > ... > >URL is generated with _ZopeId but when request come > to > > > >ZServer VHM mapping doesnt works correct.
