I was "almost" tempted to move the project to PHP+Apache+PostGres. But I am a ZopeHead ... always has been a big fan. I have decided to use Zope274 for now. Hope fully I wont have major problems when I upgrade to Zope3. Now what I need is working a postgres DA for Zope274..... Cheers Shapehead

recursion problem with newer security machinery
by Christopher N. Deckard 20 Jan '05

Howdy, We recently upgraded to 2.6.4, and are now having a problem with our custom UserFolder Product. I've narrowed everything down to a few methods, but am at a loss on how to fix it. In our UserFolder User class, we have overridden getRolesInContext to look for a Python Script (we call it an "authorize script"), in parent folders of the published object. It then calls each script to programatically add roles at runtime. This works great with Zope 2.6.2. I have noticed that in Zope 2.6.4 the method Bindings._getContext in Shared/DC/Scripts/Bindings.py has new validate code in it. I believe this is what is causing the problem for us. What is strange is that this is only a problem when using ExternalEditor, and when the container of the object we are trying to edit contains an "authorize script". From the ZMI there are no problems, and from folders under the folder with the "authorize script" there are no problems editing with ExternalEditor. Any help would be appreciated. Below is our code, and the two _getContext implementations for quicker reference. Thanks, -Chris This is our User.getRolesInContext: def getRolesInContext(self, object): """Return the list of roles assigned to the user, including local roles assigned in context of the passed in object.""" name=self.getUserName() roles={} additional_roles = self.getRoles() local={} authorize={} object=getattr(object, 'aq_inner', object) # Get local roles and roles assigned dynamically from # the auth_meth methods while 1: local_roles = getattr(object, '__ac_local_roles__', None) if local_roles: if callable(local_roles): local_roles=local_roles() dict=local_roles or {} for r in dict.get(name, []): local[r]=1 # This adds roles from authorize scripts # in all acquisition parents, much like # local roles are added # Check to make sure that the auth_meth # that we are calling is an actual method # in the container and not part of the # product objects = getattr(object, 'objectIds', None) if objects: if callable(objects): if self.folder.auth_meth in object.objectIds(): authorize_roles = getattr(object, self.folder.auth_meth, None) if authorize_roles: if callable(authorize_roles): try: authorize_roles=authorize_roles(directory=self.directory) list=authorize_roles or [] for r in list: authorize[r]=1 except: pass inner = getattr(object, 'aq_inner', object) parent = getattr(inner, 'aq_parent', None) if parent is not None: object = parent continue if hasattr(object, 'im_self'): object=object.im_self object=getattr(object, 'aq_inner', object) continue break # Add additional roles # the roles object here is different from the # BasicUser roles object because it is a list of roles # and not a method.

See http://dev.zope.org/Wikis/DevSite/Projects/ComponentArchitecture/RoadMap Plone may release a new version for Zope 3 after it comes out, but not for Zope X3.

Zcatalog searches
by Brian Ling 20 Jan '05

20 Jan '05

Hi all, I've setup a site search using ZCatalog and ZCTextIndexs that's happily doing what I want, but I'd like to take a stage further. Is there a way using the ZCatalog Brain objects returned by the ZCatalog search to get the text that actually caused the match? I'm trying to end up with a preview of the area of the content that caused the match, or is a different approach needed? The only way I can think of doing this at the moment is to get the actual content object via the ZCatalog brain object and then re-run a regex search on the content, pulling out the text around any match. This just seems the wrong way forward is there a better way? Thanks for any pointers, I'm still very much in the newbie class at present.

You can also have a look a SpeedPack to speed up TAL. See : http://psyco.sourceforge.net/ to download and install psyco And then see : http://sourceforge.net/project/showfiles.php?group_id=55262&package_id=10732 6 To only use TAL optimization, you change : PATCH_CMF = True To : PATCH_CMF = False in config.py This works fine on Zope 2.7.3 Pascal -----Message d'origine----- De : zope-bounces+pperegrina=lastminute.com(a)zope.org [mailto:zope-bounces+pperegrina=lastminute.com@zope.org]De la part de Chris Withers Envoyé : jeudi 20 janvier 2005 10:44 À : Robert Hill Cc : zope(a)zope.org Objet : Re: [Zope] TALInterpreter Performance Robert Hill wrote: > Hey all, > > I just installed Zope Profiler to check out the performance of my pages and I noticed that I have a few bottlenecks on TALInterpreter calls that I'd like to clean up.

question on objectValues
by Wombie Tomek 20 Jan '05

20 Jan '05

I've trying to write a little dtml method that will out put a list of images in a given location using a variable "path" with is passed from a form. ?path=photos1... but haven't had much luck because it doesn't seems to interpret the variable i want to be a path. if i put the path directly into the program ie "photos1.objectValues()" it works. but i need it to be feed from a variable path. <dtml-in expr="path.objectValues('CMF ZPhotoSlides')"> <folder path="wombat/&dtml-id;/" name="&dtml-title_or_id;" amount="<dtml-in expr="objectValues(['CMF ZPhoto'])"><dtml-if sequence-end><dtml-var count-description></dtml-if></dtml-in>"/> </dtml-in> this should simple ;-) but i'm missing something. thanks... holden

The issue is that the per call time seems a bit high on some of these.

Hello Zope-Users Does anyone has a workaround for http://zope.org/Collectors/Zope/569. I´ll parese the cookie by an apache module. The module checks the cookie and "says" it´s not valid I think this is because the cookie is quoted. Any hints? thx christian

question on howto readfile(img)
by Wombie Tomek 20 Jan '05

20 Jan '05

i have what i hope is a fairly easy question that's been alluding me for a few hours. i've been trying to rewrite a little script i wrote in php long ago. i need to have a script, which returns an image once it decides it exists... the only thing i don't have worked out is how to do something like this: <dtml-var RESPONSE.setHeader('Content-Type','image/jpeg')> readfile(img+?size=thumb); <<----not sure how to do this, this is from php img being a path given through the url: ie ?img=somefolder/someimage.jpg thanks, holden
