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

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> </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

Problem displaying Informix INTERVALs using DTML
by Raymond Kelly 01 Aug '00

01 Aug '00

Hi, I am using Zope on a PC running on NT and using ODBC to connect to a Informix database. I am running a query that returns a column of INTERVAL type, calculated by subtracting to DATE types. The query, when tested using the test tab, displays the results as I expected. However, when I try to display the results using either a search interface, or my own DTML method, NETSCAPE 4.7 refuses to display the results. Instead it reckons it cannot handle the resultant HTML from the DTML used to produce the results page. Instead, it decides the best thing to do is save the file but when it is reloaded it load just fine. IE5 does get a little further and it will display the page but there are numerous strange characters at the end of the expected interval field. This seems like some additional characters are coming back from the query and they may cause Netscape to trip up and IE5 to display odd characters. What I have tried to do, without sucess, is to get access to the DTML, within Zope, which produces the results of a test on an SQL query. This is where the solution lives!, but I plain just can't find it. I have tried formating the the INTERVAL type and truncating but nothing yields the same results as the 'test' DTML. Any ideas for a poor Zope newbie. Thanks Raymond

One response, Protection of the system from simple mistakes by trusted users? Also root can do a lot more, such as putting interfaces into promiscious mode.

dtml-tree question
by Jonothan Farr 01 Aug '00

01 Aug '00

What is the difference between using the dtml-tree tag in a dtml method and using it in a dtml document? I have code that works perfectly in a dtml method but when I try the exact same code in a dtml document it doesn't display anything. Is it because the document is at the top of the namespace stack instead of the request object in the dtml document case, but not in the dtml method case? My branches method is a zsqlmethod that acquires its parameter from the namespace. Here's the code, if that helps: <dtml-var standard_html_header> <dtml-tree branches=select_subprojects id=project_id> <a href="edit_project?project_id=&dtml-project_id;">edit</a>  <a href="view_project?project_id=&dtml-project_id;"><dtml-var project_name></a> </td> <td align=right valign=top><dtml-var task_count> </dtml-tree> <dtml-var standard_html_footer> select_subprojects is a zsqlmethod, the fields are project_id, project_name, and task_count. It takes one parameter, project_id which it acquires from the result set of the previous call to itself. I'm stumped. I could just use a dtml method instead of a document but I want to understand this. Thanks, --jfarr
