tracebacks
by Tom Deprez 01 Aug '00

Hi, Can somebody explain me how you can use the given tracebacks to find the possible error? For example, I get the following error and I know what causes it, but I don't know where I must go to find the code-line where the error starts: I get the following error when I use a table in which a field is defined with a default string value. eg : MY_NAME CHAR(20) DEFAULT 'tom' MY_DATE TIMESTAMP DEFAULT '6/07/2000' MY_DATE TIMESTAMP DEFAULT 'NOW' --- Zope Error Zope has encountered an error while publishing this resource. Error Type: cPickle.PicklingError Error Value: Cannot pickle objects. ---  Thanks for any advice. Tom

Re: Stability probs on Solaris? (Was: [Zope] Trouble installing on Solaris (fwd)) Solaris (fwd))
by Paul Browning 01 Aug '00

I thought I'd forward (with Tone's consent) an exchange that happened off list. We've been having problems in Bristol with Zope 2.1.6 dying under Solaris 7. (Sorry - no hard info about this, no obvious pattern.) The consensus seems to be that things appear to better with Zope 2.2 - does anyone else's experience support this?

Our servers are all pretty stable here now. We've upgraded a box to Solaris 8 and I've compiled (from src) Zope 2.2.0 on it and it's working fine. In fact, I'm using the INSTANCE_HOME, PYTHON_HOME environment variables to point to *one* installation of 2.2.0 and have 5-6 servers running from that.

ZUBB on Zope 2.2 - bug?
by Arjan Scherpenisse 01 Aug '00

01 Aug '00

Hi there, i think ive found a bug in the new ZUBB (0.5.0) on Zope 2.2. After replying on a topic, it isnt possible anymore to view that posting and its replies on it. It says: Error Type: AttributeError Error Value: 'None' object has no attribute 'created' And the traceback is: Traceback (innermost last): File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/lib/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: 00000003) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/lib/zope/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: index_html) File /usr/lib/zope/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: index_html) File /usr/lib/zope/lib/python/OFS/DTMLMethod.py, line 167, in __call__ (Object: index_html) File /usr/lib/zope/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: index_html) File /usr/lib/zope/lib/python/DocumentTemplate/DT_Util.py, line 337, in eval (Object: item_index_html(_.None, _)) (Info: _) File lt;stringgt;, line 0, in ?

copying and pasting Zclass instances?
by Darran Edmundson 01 Aug '00

01 Aug '00

Can someone point me towards docs that describe how to add copy/paste ability to my ZClass? At the moment Zope (2.1.6) throws an exception when I attempt to paste with the message "The object <id> does not support this operation". I have a nagging feeling that Zope doesn't have this ability, though I'd love to be proved wrong. Cheers, Darran.

RE: [Zope] How do I control iteration over XML elements?
by Jean Jordaan 01 Aug '00

01 Aug '00

hi Curtis Yaaay! It works :) Thanks a lot! I wouldn't have found "objectValues" on my own .. where'd you learn about that? I'm ploughing through docs and wiki's now, just don't know if they're the right ones. I also need to read more about Python .. Anyway, I messed about with your instructions a bit, and tried: <dtml-var "text_content('member')"> (which renders nothing), and: <dtml-var "text_content"> which renders: <Python Method object at 13bead8> Dunno how soon I'd've navigated that maze on my own. The "text_content" I can understand -- putting it between "" means that it should be evaluated, so text_content is evaluated without parameters, and dtml-var is being asked to render the method itself. Doing "text_content('member')", text_content is replaced by the result of evaluating it on 'member' .. this works when it's fed the output of getElementsByTagName, but since I'm already "in" the members, there aren't any member elements to be had inside them -- only their text_contents. Well, that's as far as I can puzzle it out .. Now for another question (which I'm throwing to the group seperately too): How do I show all groups that a specific member is part of? In other words, if I have: <teams> <team> <name>Ham</name> <desc>White papers, brochures, case studies.</desc> <member>Eduan</member> <member>Jacqui</member> </team> <team> <name>Green eggs</name> <desc>Green papers, brochures, case studies.</desc> <member>Tracey</member> <member>Jacqui</member> </team> </teams> how do I get "Jacqui is member of the Ham and Green eggs teams." -- jean

Querying XML in Zope
by Jean Jordaan 01 Aug '00

01 Aug '00

Hi group Here's a new thread for this question: In an XML Document, how do I show all teams that a specific member is part of? In other words, if I have: <teams> <team> <name>Ham</name> <desc>White papers, brochures, case studies.</desc> <member>Eduan</member> <member>Jacqui</member> </team> <team> <name>Green eggs</name> <desc>Green papers, brochures, case studies.</desc> <member>Tracey</member> <member>Jacqui</member> </team> </teams> how do I get: "Jacqui is member of the Ham and Green eggs teams." This code lists all the members nicely: <dtml-in "teams[0].getElementsByTagName('team')"> <dtml-in "objectValues('member')"> <dtml-var text_content><br> </dtml-in> </dtml-in> But I'd like to make a table with all the members down the left (occuring once only, and alphabetized), and all the teams each one belongs to, to their right. Is this rocket science? Eduan belongs to Ham Jacqui belongs to Ham, Green eggs Tracey belongs to Green eggs -- jean

newbie question: how do I adjust field width?
by Joe Hewitt 01 Aug '00

01 Aug '00

Hi, I'm making an input form. When I try to change the form's input field width, it automagically displays 30 char for each field. Is there any way to adjust the width? Different question: where can I find some good examples of how to validate input? Thanks. -- Joe Hewitt email: joe(a)apollo.wuacc.edu Linux Coordinator Washburn University Law School
