ANNOUNCE: Zope 2.2.5 released
by Brian Lloyd 08 Jan '01

08 Jan '01

Hello all, Zope 2.2.5 has been released - you can download it from Zope.org: http://www.zope.org/Products/Zope/2.2.5/ This release contains a number of bug fixes, and includes all Hotfixes to date. It includes the fix for a memory leak that could occur when accessing SQL data through aliased names, a fix for a problem with contention between concurrent POST requests and a number of fixes to improve support for current WebDAV-aware clients such as Adobe GoLive. Over 60 Collector issues were closed out in preparing for the 2.2.5 release - thanks to those who submitted patches and helped to investigate bugs and verify fixes. Note that this release contains a change to the ExtensionClass binary - if you are running a source release you should rebuild the Zope binaries after upgrading or applying a "diff" update. For more information on what is new in this release, see the CHANGES.txt and HISTORY.txt files for the release: http://www.zope.org/Products/Zope/2.2.5/CHANGES.txt http://www.zope.org/Products/Zope/2.2.5/HISTORY.txt Note that we have also posted "diff" updates as .tgz files that will let you easily upgrade an existing 2.2.x site. These updates are available for those currently using the 2.2.x source release or the 2.2.x binary releases. To apply a differential update to your site: - download the appropriate .tgz file from zope.org - shutdown your Zope process - copy the .tgz to your Zope directory and extract it - run w_pcgi or wo_pcgi *if you are not using a binary release* - restart your process Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

by Andy McKay 08 Jan '01

08 Jan '01

Is there a product / some code for maintaining free Zope sites where members log in get a some space etc. For example Zope.org or nipltd.com? Theres plenty of advanced login products (Login Manager, Membership etc), but it would be nice to download one without having to add to it? Cheers. -- Andy McKay. ActiveState.

RE: [Zope] filename extension

Perhaps I am wrong here, but couldn't one just use indirect variable lookup within the expression to access the method. There has got to be a way to use _.getitem for this purpose inside the <dtml-in>, since by default, it doesn't automatically render the method, but I'm not sure how one would pass the param to the method? Anybody have syntax that would work?

Re: [Zope] LoginManager with SQL and Skinscript: adding properties to propertysheet propertysheet

You may have noticed my silence on property sheets... At first, I didn't expect to use them, because I expected only members to edit their "properties" and I'm certainly not going to expose the standard Zope management interface to them. After going through the latest PTK sources some more, it looks like I may try using them after all. In either case, the important things to remember are: - The actual property data isn't stored in the ZClass or its property sheets, and the Skinscript code makes the ZClass "property" attributes have values with or without property sheets, and - The ZClass instances are ephemeral -- nothing is expected to store them for any length of time (though they may be cached). > I created LoginManager:LoginUser subclassed zclass def for a user with > a propertysheet Basic. > > It had properties password and email.

Is there a > way around this problem? I think you'll have to delete the whole ZClass and start over :-(. This shouldn't be too much of a pain because you shouldn't have any instances to worry about. If you've written custom methods, you'll want to copy them someplace before deleting the class. Hope this helps, Dan Pierson

zclassReverse problem
by Bill Welch 08 Jan '01

08 Jan '01

I get back exactly nothing, no 'Not Found', no classes/attributes. I believe that I've installed correctly. When I ask for a product that doesn't exist, I get a traceback that starts in Extensions/zclassInfo.py. I've tried in on Membership, LoginManager, ZPatterns, Poll, Etailer, and zCommerce. Zope 2.2.2, linux. Bill.

Newbie Questions
by Alex Reid 08 Jan '01

08 Jan '01

I am finally starting to make some decent progress with Zope now... more and more I think to myself ... "I wonder if...." and most of the time I am pleasantly suprised when it works! A couple of quick questions: - How would I display the value at a variable whose name is stored in another variable? In Perl this would simply be a double dollar type of affair $name = "Alex"; $myvar = "name"; print $$myvar; - I am creating a 'form' method so I don't have to create separate forms for INSERT and UPDATE actions. This works, only how do I tell Zope to ignore the fact that <dtml-var company_id> doesn't exist when in INSERT mode? It is there in the value="" parameter for the edit mode to pre-populate the element. Thanks in advance Alex

Re: Raise a Login Dialog
by Chris McDonough 08 Jan '01

08 Jan '01

Michal, Please use the Zope list to ask questions, thanks. The answer is somewhat silly. When you call this method, and you enter authentication credentials, Zope tries to render the method. Rendering the method raises an unauthorized. Then you enter your credentials again. And it raises unauthorized again. Etc. The purpose of raising unauthorized here is to clear your credentials from the browser. If you hit OK on the dialog (without entering any username or password), and then visit *another* method, you will be able to log in as a different user. I hope this makes sense, - C ----- Original Message ----- From: "Michal Krejza" <michal.krejza(a)disagroup.cz> To: "'Chris McDonough'" <chrism(a)digicool.com> Sent: Monday, January 08, 2001 9:26 AM Subject: Raise a Login Dialog > Hi, > I try to force a popup box for logon to Zope.
