Adding User Roles
by David VanKirk 10 Jul '06

10 Jul '06

We're running Zope version 2.5.1 here in the office. My boss was telling me when he tries to add a user role under the security tab, it won't show up as a selectable role under the acl_users folder. Anyone ever seen this problem before? -- David VanKirk

Newbie questions about MVC, Continuations, Persistence
by Andrew Madu 07 Jul '06

07 Jul '06

Hi, I am completely new to the world of Zope and would like to know how zope handles the following: 1. MVC 2. Continuations 3. Persistence ala Hibernate I have an existing cocoon project, 2.1.8, which I was contemplating on moving either over to webobjects or zope. I have a number of java classes which I would like to continue to use and wondered whether zope would be able to plug into these classes, or are am I looking at a complete re-build for those as well? One major issue I have is with a paypal SDK I am currently testing which handles merchant banking, are there any merchant banking SDK's out there which are zope compliant that anyone know of? regards Andrew

I read all the documentation I could find and followed it to the word. I believe other factors came into play which resulted in a non-working installation.

Just as your said, you don't have a good overview of the system you are working with. So I would suggest to you to dig in. If you have read all the docs and "followed it to the word", am sure you will be better than me by now. Your intention of using this mailing list for help is not wrong, but your way of seeking help can be unappreciated by those who are in this maililng list. At any case, try uninstalling everything, and start from scratch again. If you have done this already, I suggest you look through the basic commands of your distro and try to dig through the issue. It may not be Zope's error in the first place, it could be your human error, configuration of your server, or whatever. A piece of advice. Install zope in your PC first before the server. I hope you have the same distro too, that helps alot, I mean ALOT!!

Using property() function in Zope 2.8
by Max M 06 Jul '06

06 Jul '06

I needed to dynamically generate local roles for an Archetypes based content object today. Different layers in my Plone stack breaks all rules and reads the __ac_local_roles__ variable directly, instead of calling get_local_roles() So to maximize the compatibility between Zopes zmi and Plones local roles management I wanted to make '__ac_local_roles__' a property with setters and getters. My AT class was based via a few hops on: 'from ExtensionClass import Base'. And as far as I understand from the release notes Zope 2.8.x should use extension classes based on new style classes. So the property function should work. This code below works in plain Python. But when I add them to my zope class, and run the tester() method I get an "Attributer Error: __ac_local_roles__" Any ideas/comments? # -*- coding: latin-1 -*- class PropTest: def get__ac_local_roles__(self): return self.__mxm__ac_local_roles__ def set__ac_local_roles__(self, value): self.__mxm__ac_local_roles__ = value def del__ac_local_roles__(self): del self.__mxm__ac_local_roles__ __ac_local_roles__ = property(get__ac_local_roles__, set__ac_local_roles__, del__ac_local_roles__, "Local roles on object") def tester(self): return self.__ac_local_roles__ if __name__ == '__main__': p = PropTest() p.__ac_local_roles__ = 'working' print p.tester() -- hilsen/regards Max M, Denmark http://www.mxm.dk/ IT's Mad Science Phone: +45 66 11 84 94 Mobile: +45 29 93 42 96

Trying to trap ConflictError
by Jonathan 06 Jul '06

I am trying to trap the following error: Traceback (innermost last): Module Zope2.App.startup, line 173, in zpublisher_exception_hook Module ZPublisher.Publish, line 121, in publish Module Zope2.App.startup, line 240, in commit Module transaction._manager, line 96, in commit Module transaction._transaction, line 380, in commit Module transaction._transaction, line 378, in commit Module transaction._transaction, line 433, in _commitResources Module ZODB.Connection, line 484, in commit Module ZODB.Connection, line 526, in _commit Module ZODB.Connection, line 554, in _store_objects Module tempstorage.TemporaryStorage, line 200, in store ConflictError: database conflict error (oid 0x39b0, class BTrees._OOBTree.OOBucket, serial this txn started with 0x0366974da4fd2288 2006-07-04 13:33:38.669252, serial currently committed 0x0366974da54d9fcc 2006-07-04 13:33:38.742942) in an external method, as follows: folder = self.unrestrictedTraverse(TEMPFOLDERIMAGES, None) try: folder.manage_addImage(imageId, imageData) except: <handle error message and return gracefully code> But the try/except block is not catching the error! (the error continues to show up in error_log) (note: I started by trying "except ConflictError:", but that was not working, so I went to the bare try/except) The traceback does not show where the error originates in the external method, but there is only one place where the external methods writes to TemporaryStorage. Does this indicate that the error is not bubbling up properly? Any ideas as to why the error trapping is not trapping? (running Zope 2.9.2, debug=on) Thanks, Jonathan
