getURL and url_quoting
by lambert muhr 28 Jan '02

I am cataloging mysql-data with zcatalog following the how-to provided by zope-member rbicker. this works fine. since I use batch-processing to build web pages containing e.g. 3 mysql data records per page, the uid's, hence the url's of the zcatalog's objects are e.g.: /base/select_mm_url/2/show_intro?start=4 this url, I build dynamically from a python script, which catalogs the mysql data: for chapter in container.search_mms(): container.catalog_object(chapter,'/base/select_mm_url/' + chapter.mm_id + '/show_intro?start=' + chapter.mms_id) [works fine ...] in the search results' page I use the following code to link to the results: <A HREF="&dtml.-getURL;">link</a> unfortunately, the link on the web page turns out like this: /base/select_mm_url/2/show_intro%3fstart%3d4 what is my mistake? I was believing I would have to turn off the automatic url-quoting using the entity reference '&dtml ....;' by putting the '.' after '&dtml'. but it seems, this doesn't work with 'getURL'. if so, what other possibilities do I have to "get" the results' "url"? thanks for any hint. lambert

Confused: Does PersistentList exist?
by Lennart Regebro 27 Jan '02

27 Jan '02

I found seceral seemingly up to date docuemnts claiming that both PersistentMapping and PersistentList exists and is included with Zope. However, I couldn't find PersistentList, so I thought that it had been added after 2.3.3, which I am using. So I checked the CVS. Nope, nothing there. So whats the deal here, really?

Product upgrades
by brian.r.brinegar.1 26 Jan '02

26 Jan '02

I have done work on a couple of products and one thing I've noticed is if you change what is done in the __init__ method of an object there isn't a good way to make the change so that it takes effect on old instances of the object. For example: def init(self): self.data.append('cow') becomes: def init(self): self.data.append('cow') self.data.append('horse') things created with the first constructor must be removed and recreated if 'horse' is to be added. Is there a way to go through and update old instances of a product to a newer version? Or should backwards compatibility be designed into the product? Thanks, --Brian

Because we have thousands of portal document in our website. It takes more CPU and memory to catalog object. Also database size increase quickly. Howard -----Original Message----- From: R.

Why do you think storing metadata in an sql database would improve performance? I'm not saying it wouldn't, but it's not obvious to me that it would. --RDM

RELEASED - StandaloneZODB 1.0 release candidate 1
by barry＠zope.com 25 Jan '02

25 Jan '02

I'm please to announce the first official release of StandaloneZODB, the Python object persistency system also known as the Z Object Database. ZODB is the object-oriented database underlying Zope; the StandaloneZODB project's goal is to provide those same facilities to non-Zope related Python applications. Today we are releasing StandaloneZODB 1.0 release candidate 1. We expect to release the final version on 1-Feb-2002. StandaloneZODB is based on the same code as the ZODB in Zope, albeit on a separate release branch. Its inspiration comes from Andrew Kuchling's StandaloneZODB project on SourceForge. While there are still some differences, the Standalone 1.0 release is the first on the path toward convergence. Subsequent releases should complete the merge of Andrew's and Zope Corporation's packages. The StandaloneZODB release includes the following components: - Core ZODB, including the persistence machinery - Standard storages such as FileStorage - Supporting modules such as ExtensionClass - The persistent BTrees modules - ZEO - Experimental Berkeley storages - Some documentation <wink> See the README file for details on building and installing StandaloneZODB. For details on using ZODB, see Andrew's included user guide. StandaloneZODB 1.0c1 is released under the ZPL 2.0. It should be compatible with all Python versions from Python 2.1 to Python 2.2. It may or may not work with versions earlier than Python 2.1. Download StandaloneZODB-1.0c1.tgz from: http://www.zope.org/Products/StandaloneZODB and visit the StandaloneZODB Wiki page at: http://www.zope.org/Wikis/ZODB/StandaloneZODB See also: http://www.zope.org/Wikis/ZODB/FrontPage for more information about our long-range ZODB plans. Enjoy, -Barry Barry A. Warsaw Zope Corporation, Pythonlabs barry(a)zope.com

Very, very strange problem with 2_4-branch
by Matt Behrens 25 Jan '02

25 Jan '02

After upgrading to 2_4-branch, I started having some problems with authentication, or so I thought. I have a standard user folder in the root and an XUF in a top-level folder. After much wailing and gnashing of teeth, I dug into _check_context, and added a debug statement, now I have: def _check_context(self, object): # Check that 'object' exists in the acquisition context of # the parent of the acl_users object containing this user, # to prevent "stealing" access through acquisition tricks. # Return true if in context, false if not or if context # cannot be determined (object is not wrapped). parent = getattr(self, 'aq_parent', None) context = getattr(parent, 'aq_parent', None) if context is not None: if object is None: return 1 if not hasattr(object, 'aq_inContextOf'): if hasattr(object, 'im_self'): # This is a method. Grab its self. object=object.im_self if not hasattr(object, 'aq_inContextOf'): # Object is not wrapped, so return false. return 0 zLOG.LOG('BasicUser._check_context', zLOG.DEBUG, '%s.aq_inContextOf(%s, 1) returned %d' % (object.getPhysicalPath(), context.getPhysicalPath(), object.aq_inContextOf(context, 1))) return object.aq_inContextOf(context, 1) I am getting the following log output: 2002-01-25T16:36:23 DEBUG(-200) BasicUser._check_context ('', 'zope').aq_inContextOf(('', 'zope'), 1) returned 1 and 2002-01-25T16:38:07 DEBUG(-200) BasicUser._check_context ('', 'zope', 'dept', 'is', 'alerts').aq_inContextOf(('', 'zope'), 1) returned 0 Now, the weird part is that this problem is sporadic. It will go away and reappear with some frequency. Any ideas? Anyone?

How to automatically redirect publishing request to another folder?
by Craeg K. Strong 25 Jan '02

25 Jan '02

Hello: We have a Slideshow product that is similar to OrderedFolder in that it maintains an ordered list of contents. Each subfolder represents a slide. To view a particular slide, you navigate to the subfolder, it automatically calls "index_html," and there's your slide. All of the slides actually acquire their index_html DTMLDocument from high up on the food chain. The index_html in turn calls <dtml-var body> and the body is, of course, different for each slide. This is convenient, b/c each slide shares header/footer/etc. My problem is this. When you type in the URL of the top level folder (that is, the slideshow folder itself) I want Zope to behave as if you typed in the URL of the first slide automagically. The Slideshow product has an easy way to get our mitts on the firstSlide object, so that part is not a problem, but I cannot get it to work. Of course, if I create an index_html() method directly in my Slideshow.py, that screws up my acquisition. Zope dies with an infinite recursion. Next try: using __bobo_traverse__() That is a little bit nasty, b/c you have to figure out whether you are the "end destination" or if Zope is just "passin' thru." [ See http://www.zope.org//Members/andym/wiki/MessingWithTraversal ] Nothing works quite right. Conceptually I know what I want to do: call index_html on firstSlide() in the _context_ of firstSlide(). However, my Zope Zen is failing me. Has anyone done something like this? Thanks in advance! --Craeg
