Copying objects
by Jesper Holmberg 19 Nov '01

19 Nov '01

Hi all, I have a problem that's driving me crazy. Hopefully someone here can help me sort it out. I have two products, Itinerary and Step. They are both subclasses of "Folder". I am parsing an XML-file into a DOM, using the xml.dom.minidom. The resulting DOM object is an attribute of an Itinerary instance. With the help of this DOM, I then create a hierarchy of the Itinerary and several Steps. For each DOM-element of type "Step", I create a Step in Zope. Each Step has as an attribute the node in the DOM to which it is associated. So, in the Itinerary code, I have something like this: for childNode in self.dom.childNodes: if childNode.tagName == "Step": id = 'step_%d' % len(self.objectIds()) manage_addStep(self, id, childNode) So far, so good. I get a hierarchy of Steps that expresses my DOM. But here my troubles begin. I want to add objects of type Link to the Itinerary folders, and to the Step folders. These changes should be reflected in changes in the DOM. So I have this method: def manage_addLinkAction(self, id, node=None, REQUEST=None): "Add a Link to a folder." ... self._setObject(id, Link(id, node)) linkNode = minidom.Element("Link") self.node.appendChild(linkNode) This does not give any errors. BUT: if a Link is added directly to an Itinerary, the change is reflected in the DOM, but this does not work if I add a Link to a Step. It thus seems to me that the Step actually has a copy of the node it was given as parameter when it was created, and not the original node itself. Since it's only the copy that is being manipulated by the adding of nodes, the original DOM which rests in the Itinerary object is not affected. I don't understand why this is so. It doesn't fit with how I had understood the treatment of objects as parameters in Python. Could someone please help me sort this out. If I have not given enough information, I'd be happy to supply it. TIA, Jesper -- Jesper Holmberg |"But how can | jesper.holmberg(a)enst-bretagne.fr | one be warm | ENST Br, BP 832, 29285 Brest, FRANCE | alone?" |

Is there ZmxODBC anywhere for python 2.1 ?
by Krone, Armin 19 Nov '01

19 Nov '01

Hello, I tried to run ZmxODBC in my actual Zope-Version 2.4.1 with Python 2.1. This fails because ZmxODBC is precompliled for Python 1.5. Well I know, compile it for 2.1 would be a solution but I had no success :-( Has anybody a running version for my System? Or have you a tip how to compile this ? mit freundlichen Grüßen Armin Krone TeleCash GmbH Produktmanagement Internet Payment Systeme Support Internet Theodor-Heuss-Str. 8 D-70174 Stuttgart Tel. +49 (0)711 16264 924 Fax +49 (0)711 2270644 mailto:Armin.Krone@telecash.de http://www.telecash.de

Maybe a stupid newbie question - forcing an in loop to the Root Folder's context.
by Jim Nicholson 19 Nov '01

19 Nov '01

I've created a method in the root folder that basically does some dtml-in looping over objectValues. It works fine when included (via var) in other methods and docs in the root window. The problem is that I want it to be aquired by sub-folders, but want it to still loop through the root folder's contents. In other words, I should be able to call my method anywhere in sub-folders or items deep in the site, and still get a list of objects in the root folder. Can I do this in DTML? Does it require python? Does it need to be an external script? Can someone point me in a direction? - Jim dongle(a)home.com

Change title of ZClass Help Folder?
by Lars Heber 19 Nov '01

19 Nov '01

Hello all, having renamed a product with ZClasses inside from ABC to XYZ, I also want to change the title of the help topics. But the help folder in my ZClass still has the title ABC. But this now should also be XYZ. How can I do that? There's no Properties tab in the help folder. I also tried to programmatically (with DTML) change the property title of the help folder - this folder does not have a property "title"! What can I do? Do I have to hack some files somewhere? In the folder lib/python/Products the ZClass products don't appear. So where do I have to change things? Thanks. -- Lars Heber, mailto:Lars.Heber@t-systems.de T-Systems, debis Systemhaus GEI GmbH, Geschaeftsstelle Sachsen

Calculation with 2 DateTime objects
by Gitte Wange 19 Nov '01

19 Nov '01

Hello, I have been working on this problem for some time now but I cannot seem to find a solution. What I need to do is to find a date (with time) from some informations .. I have a start date for an event, I have a timestamp for an encode start time and I have a timestamp for when a clip starts ... Now I want to find the RealTime date (with time) for the clip ... The code I have looks like this: event = eventstart.Date() enc = event + ' ' + str(encstart) + ' GMT' tcpoint = event + ' ' + str(tc) + ' GMT' (the reason for inserting the eventstart date in the enc string and the tcpoint string is because I want to create 2 DateTime objects - but that requires a date) ... Now I want to say: real_tc_time = DateTime(enc) + DateTime(tcpoint) But ... I get an error saying that you cannot add 2 DateTime objects ?? So how could I do this calculation ? -- Gitte Wange Jensen Sys Admin, Developer and a lot more MMmanager.org Aps, Denmark Phone: +45 29 72 79 72 Email: gitte(a)mmmanager.org Web: www.mmmanager.org Quote of the day: Give it your worst.

Hang while waiting for external process
by Paul Winkler 19 Nov '01

19 Nov '01

I'm using zope 2.4.3 on linux (redhat 7 with kernel 2.4.14), playing around with the Photo product (nice one!). I've had a few zope freezes, and finally found a pattern: Occasionally, if using ImageMagick to do the rendering for Photo, convert will fail to complete and Zope will then become completely unresponsive. Browser requests do nothing. This is weird. I can understand how one of the Zope threads might get stuck waiting for the never-ending external process; but why should Zope become completely unresponsive? Shouldn't the other threads keep responding? And is there a way to set a timeout for an external process, such that zope can recover if it fails to return for too long? Here's output of ps showing the defunct convert process: (snip) 891 pts/0 S 0:00 python2.1 /home/pw/Downloads/Zope/z2.py -M /home/pw/C 896 pts/0 S 0:09 \_ /usr/local/bin/python2.1 /home/pw/Downloads/Zope/ 919 pts/0 S 0:00 \_ /usr/local/bin/python2.1 /home/pw/Downloads/Z 920 pts/0 S 0:29 \_ /usr/local/bin/python2.1 /home/pw/Downloa 1001 pts/0 Z 0:00 | \_ [convert <defunct>] 921 pts/0 S 0:05 \_ /usr/local/bin/python2.1 /home/pw/Downloa 922 pts/0 S 0:00 \_ /usr/local/bin/python2.1 /home/pw/Downloa 923 pts/0 S 0:00 \_ /usr/local/bin/python2.1 /home/pw/Downloa I can then get zope to restart by killing any of the zope PIDs. Here's the big M log leading up to the freeze - nothing unusual:... requestprofiler.py doesn't show any hangs in this log... $ tail -f bigM E 147423764 2001-11-15T17:36:05 B 143413564 2001-11-15T17:36:16 GET /test_crap/my_image_library/nothing I 143413564 2001-11-15T17:36:16 0 A 143413564 2001-11-15T17:36:16 500 2485 E 143413564 2001-11-15T17:36:16 B 147432596 2001-11-15T17:36:25 GET /test_crap/my_image_library/lilaq-logo.jpg I 147432596 2001-11-15T17:36:25 0 A 147432596 2001-11-15T17:36:25 304 282 E 147432596 2001-11-15T17:36:25 -- paul winkler home: http://www.slinkp.com music: http://www.reacharms.com calendars: http://www.calendargalaxy.com

Introspection?
by azbok＠yahoo.com 19 Nov '01

19 Nov '01

Hi I'm wondering how one would figure out what methods/globals that are available for use in a zope python script? I know about the dirs(), globals() and locals() functions that you can use in regular python, but I can't use them in zope. I get a NameError. Is there any way to use the builtins functions? Thanks for info
