Why do you want to recode into DTML? I think that is piece of good code and much faster than DTML. You could try following replacing (original line of your code, follows with DTML code), but not tested: > rec = context.test_select_sql() <dtml-call "REQUEST.set(rec , test_select_sql())"> > print "Fields definitions" Fields definitions > recordset = rec.dictionaries() <dtml-let "recordset = rec.dictionaries()" > rownum = 1 <dtml-call "REQUEST.set(rownum,1)" > for record in recordset: <dtml-in recordset> > print "Row %d" % (rownum), "check", record Row <dtml-var rownum>, check <drml-var sequence-item><br> > rownum = rownum + 1 <dtml-call "REQUEST.set(rownum,rownum+1)" </dtml-in> and so on on the rest of code. > for key in record.keys(): > print key, "=", record[key] > print "-" * 80 > return printed

This has not to do anything with read-only. Does anybody know what I have to configure additionaly, that read-only works? I run Zope 2.8.4 on windows. Many thanks in advance, Ulla.

manage_cutObjects/manage_pasteObjects problem ...
by Ajay Deshpande 02 Aug '08

02 Aug '08

Hi all: Ive been trying to cut objects from one context and paste them into another using a script python. But I get a "CopyError" when I try doing this. This is my code snippet and the traceback ... Snippet... ... obj = context.restrictedTraverse(path) obj_parent = obj.aq_inner.aq_parent dest_folder = context.Dest # this is a folder object copy_info = obj_parent.manage_cutObjects((context.getId())) dest_folder.manage_pasteObjects(copy_info) ...

I cannot perform this operation directly using the ZMI also. So it is not a problem with the script. Some issue in CopySupport. I searched for the resolution and found that CopySupport needs to be patched. But I couldnt find the patch anywhere. My Zope is 2.9.4-final, Python2.4.3. Any help is greatly appreciated. TIA, Aj "And the trees are all kept equal By hatchet, axe, and saw"

Zope product and dtml-tree
by Rowan Woodhouse 31 Jul '08

31 Jul '08

Hi, I'm developing a Zope product that uses a dtml file to generate the html page. I'd like to include a dtml-tree based tree for navigation on the page. The custom object inherits from SimpleItem. When I include the follow code in the dtml file: <dtml-tree> <dtml-var id> </dtml-tree> I get the following exception: An error was encountered while publishing this resource. exceptions.KeyError Sorry, a site error occurred. Traceback (innermost last): * Module ZPublisher.Publish, line 202, in publish_module_standard * Module ZPublisher.Publish, line 150, in publish * Module ZPublisher.Publish, line 119, in publish * Module ZPublisher.mapply, line 88, in mapply * Module ZPublisher.Publish, line 42, in call_object * Module Products.WellGroup.WellGroup, line 110, in index_html * Module App.special_dtml, line 65, in __call__ * Module DocumentTemplate.DT_String, line 476, in __call__ * Module TreeDisplay.TreeTag, line 88, in render * Module TreeDisplay.TreeTag, line 192, in tpRender KeyError: 'URL' If I add a class variable called URL I then get a key error for RESPONSE. My understanding from documentation is that Item (from which SimpleItem inherits) gives the product basic dtml-tree support. I can't find any examples that spell out how to write a product that supports dtml-tree tags. Could someone point me in the right direction? Thanks, Rowan

Problems with buildout and zope.interface
by Christian Scholz 31 Jul '08

31 Jul '08

Hi there! I am trying right now to convince people to use buildout and ZCA for the Open Grid Protocol project but it turns out that it's not working as expected. So maybe somebody on here can help me :-) The setup is Mac OSX 10.5.4 with Python 2.5.1 installed and apparently a zope.interface egg inside the standard install of Python of version 3.3.0. (you can see the contents of the lib dir her: http://pastebin.com/d3f5fb455) On some machines it now seems that this version is used instead of using a newer one the system wide installed one is used (for some reason not on my own machine), so the for instance the testrunner script looks like this: http://pastebin.com/d1a1024d2 (as you can see the standard lib is put into the path but not a separate zope.interface egg). The problem it comes down to when running buildout is the following: http://pastebin.com/d1ec846fa The important lines are probably: # File "/Users/tess/pyogp/eggs/zope.security-3.5.1-py2.5-macosx-10.5-i386.egg/zope/security/interfaces.py", line 20, in <module> # from zope.interface.common.interfaces import IException, IAttributeError # File "/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/zope/interface/common/interfaces.py", line 80, in <module> # classImplements(OverflowWarning, IOverflowWarning) # ZopeXMLConfigurationError: File "/Users/tess/pyogp/src/pyogp.lib.base/pyogp/lib/base/configure.zcml", line 6.2-6.55 # ZopeXMLConfigurationError: File "/Users/tess/pyogp/eggs/zope.component-3.4.0-py2.5.egg/zope/component/meta.zcml", line 7.4-11.10 # NameError: name 'OverflowWarning' is not defined So zope.component 3.4.0 probably needs zope.interface 3.4.x but installed is 3.3.0. Now my question is: How can I solve this problem. I think I tried to put zope.interface>=3.4 into all sorts of places but one outcomes only seemed to be a version conflict saying that 3.3.0 is installed already (unfortunately I also cannot test this myself as in my case it's working). Here is the buildout.cfg: http://svn.secondlife.com/svn/linden/projects/2008/pyogp/buildouts/libdev_m… There also is a setup.py which contains the following dependencies: install_requires=[ 'setuptools', # -*- Extra requirements: -*- 'zope.interface>=3.4', 'zope.component [zcml]', 'WebOb', 'wsgiref', 'grokcore.component', ], (http://svn.secondlife.com/svn/linden/projects/2008/pyogp/pyogp.lib.base/tru…) And you can find the whole buildout here: http://svn.secondlife.com/svn/linden/projects/2008/pyogp/buildouts/libdev_m… (this is a special version which only runs with Python2.5 and installed a development version of setuptools which I bundled with it because of the problems with subversion 1.5. I suspect though that it also fixed some other bugs as people here constantly seemed to have problems with buildout which now seems to be reason enough to move away from buildout and the Zope Component Architecture). Hope somebody can help :-) Thanks!

Zope 3 Skins - Virtual/Minneapolis Design Sprint for E-Democracy.Org
by Steven Clift 30 Jul '08

30 Jul '08

Would you like to put your mark on the next Mailman/Google Groups/etc.? E-Democracy.Org is plotting a design sprint for its use of the GPL open source GroupServer - http://groupserver.org - tool that we use to host local and neighborhood issues forums - http://forums.e-democracy.org - in the U.S., England, and New Zealand. Zope-based, GroupServer uses Zope 3 style skins (about which our non-profit has limited understanding ... hence an opportunity to make a difference with your skills). We will be meeting in Minneapolis. The date of the sprint is contingent on who steps up. The purpose of the design sprint is to focus on developing a highly usable, yet modern "skin." Those who want to participate on a virtual basis may do so now by watching the screencasts and seeing what inspires them. More information/screencasts/RSVP from: http://pages.e-democracy.org/Design_sprint Cheers, Steven Clift team(a)e-democracy.org E-Democracy.Org P.S. One nifty new feature that we funded (the main developers - http://onlinegroups.net - are in New Zealand) is the ability to embed a YouTube video simply by including a link in your e-mail or web post to the forum. Very simple. Very easy. Example: http://forums.e-democracy.org/r/topic/3JNAWldKqp2nQ7NocsIrCn

urllib2 timeout problem inside Zope thread
by Thierry Florac 27 Jul '08

27 Jul '08

Hi, I'm currently using urllib2 to get an external URL from an internal "cron like" Zope thread. The loaded page has to manage administrative tasks before I can start other tasks into Zope internal database ; it returns partial chunks of data, but globally takes more than 20 minutes to run. Problem : when loading the page via a simple Python console, I set socket.setdefaulttimeout() and everything is OK ; but when launching the same command from inside Zope thread, I get a socket.timeout error. So my question : as I'd really prefer to keep this method call inside an internal Zope thread, how can I prevent this timeout ?
