ANNOUNCE: Zope 2.2.4 beta 1 released...
by Brian Lloyd 21 Nov '00

Hello all - Zope 2.2.4 beta 1 has been released - you can download it from Zope.org: http://www.zope.org/Products/Zope/2.2.4b1/ This release supercedes the 2.2.3 release of Friday, which had an error that prevented permissions from being acquired correctly. Until the testing infrastructure that has been started in the 2.3 CVS is more mature and there is a useful regression test rig, we'll be planning for at least one (short) beta period for third-dot releases. I expect to make 2.2.4 final in a week barring any serious problems. This bug-fix release contains the fixes for all released Hotfixes to date, as well as fixes for a memory leak in the Acquisition module, various ZCatalog fixes and a fix for the infamous "__call__" bug (and there was much rejoicing!). 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/2.2.4b1/CHANGES.txt http://www.zope.org/Products/Zope/2.2.4b1/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 Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com

Hi, How can I pass parameters to an External Method? I know of one way to do this, is to use dtml-var tag. Is there any other way? Thanks, Kini. __________________________________________________ Do You Yahoo!? Yahoo! Shopping - Thousands of Stores. Millions of Products. http://shopping.yahoo.com/

Python Method name candidate
by Hamish Lawson 21 Nov '00

21 Nov '00

I propose Python ZMethod. Rationale: The term 'Python ZMethod' identifies that this entity has methodish properties (acquisition, etc) from Zope's point of view, but distinguishes it from methods in the Python language. Furthermore the term 'ZMethod' could be used generally for any entity that Zope regards as a method; hence DTML ZMethod, Perl ZMethod, SQL ZMethod, etc. and their unrestricted counterparts - DTML ZMethod (Unrestricted), Perl ZMethod (Unrestricted), SQL ZMethod (Unrestricted), etc. Hamish Lawson ____________________________________________________________ Do You Yahoo!?

I go to the save/discard form >and the save form post looks to work okay, i.e, I have a undo log >of this commit and If I try to save again Zope tells me there >is nothing else to save in the current version. > >But... when I try to delete my version I get a VersionLockError, >and my root folder is still being locked. > >Same goes to Discard, i.e, apparentely zope do the save/discard but >the locked files/folders continues there. > >I've tryed with superuser, and even on the Control Panel Version manage, >with no luck. > >I'm using zope222. >I'm using latest release of ZEO. >I do a pack to my Data.fs on a daily basis. > >Anyone had this problem, any help? I saw in a post someone saying that a Pack to the Database solved the problem he had with versions. In fact, after doing a pack to my database I can now discard and delete my version but the save operation do some weird things like Documents become Folders !?!

XML-RPC
by David Nimmons 21 Nov '00

21 Nov '00

I am trying to develop a web based interface to automation equipment (Allen Bradley plc's in this case) to use for an operator interface. I am using SVG to develop graphics and want to use javascript to manipulate the graphics based on data from the plc. I am looking for a way to pull more data from the server without having to reload the page. My question is will XML-RPC allow this. Or does Zope have some other mechanism that would allow this. Thanks for any help.

What about putting <dtml-if "REQUEST.environ['HTTP_HOST']=='admin.website.com'"> <dtml-var my_admin_method> </dtml-if> in your standart_html_footer. In light of the current search&replace thread, remember to put admin.website.com in a variable ;->. You could also play games with mod_rewrite in order to add a spezial variable to your _apache_-environment variables (ie. this should work when running zope as cgi, and only then) RewriteEngine on RewriteRule ^admin.website.com/(.*) www.website.com/$1 [E=my_admin_trigger:on] so testing for REQUEST.environ['my_admin_trigger']=='on' should do the trick. Or you could add this variable to the url like RewriteEngine on RewriteRule ^admin.website.com/(.*) www.website.com/$1?my_admin_trigger=on Perhaps the siteroot-product might be helpful, just in case your running pure zope, I don't know though. cheers, oliver

Thanks for your reply, but the main problem is the navigation. The admin part is the normal browse-version + an admin interface at the bottom of every side. So when you are in root/main/press and you click on the new button a script adds a new object. But how do I solve the navigation problem. The buttons to the other objects(pages) are the browse-version this means you leave the admin interface every time you change your position.

If you want to use Python Methods as they are described in the Zope Book, you have to check the code out of CVS. Info on CVS access can be found in: http://www.zope.org/Resources/CVS_info Python Methods are found under Products/DC. --- Alastair

The problem is I've got a website which should have an admin-interface.This interface should only be visible if you call i.e. admin.website.com. If you call web.website.com you reach the normal browse view. The website shoudn't be doubled, but the links on the browse-view normally call the browse-view and not the admin-view.Hope you understand the prob. Thanks in advance!!
