How to avoid recursive links and make it absolute???

Hi below is my code that renders a link when a document is created. My question is: How can i avoid recursive links and make it absolute url's? Thanks..... <div tal:define="auth_filter nocall: modules/ZTUtils/LazyFilter; default_types python:( 'Document'); types types | here/show_content_types | default_types; raw_items python: here.contentValues(filter={'portal_type': types } ); items python: auth_filter( raw_items, skip='View' ); objects here/objectValues; sort_on python:(('title', 'nocase', 'asc'), ('bobobase_modification_time', 'cmp', 'desc')); sorted_objects python:sequence.sort(items, sort_on)"> <div tal:condition="items"> <table width="100%" border="0"> <tr tal:repeat="item sorted_objects"> <td class="ActionLink" align="center"> <a href="item_url" tal:attributes="href item/absolute_url" tal:content="item/Title"> Title </a> </td> </tr> </table> </div> </div>

It they're not the same type it'll never work. Unfortunately the type() built-in isn't available in DTML or Python scripts (if you go to an ExternalMethod you should be able to use it.) What you can try is this: str(i)==str(j) to compare the string representations or, if you're dealing with a certain type of number, int(i)==int(j) float(i)==float(j) In DTML, you have to call these from the namespace '_' (underscore) as so: _.str(i)==_.str(j) --jcc

Problem with Linux installation
by Yannis Lionis 06 Mar '03

06 Mar '03

Hi everybody. I'm attempting to install Zope 2.6.1 on Mandrake Linux version 9. I read the documentation and followed the instructions: unziped the files, run ./install, wrote down the login and password, set the sticky bit of /var and changed the owner of var to root (since I was installing as root), and used the ./zpasswd.py script to change the password to something more convenient, leaving the login name to 'admin'. Trouble starts here: The SETUPUID.TXT document file says I need to set the UID either in the ./z2.py, or in the ./start command line. I cannot do either! I tried the first option and typed: ./z2py -u admin What I got was the help list and at the bottom the following error messages: ./z2py: line 239: syntaxerror near unexpected token ' 0,' ./z2py: line 239: ' sys.path.insert(0,'%s/lib/python'%swhome)' So I thought I'd try the second option. I typed: ./start.py -u admin The process seemed to go fine (opened datanbase, mounted database, etc.) but a few seconds later I got a message: ERROR(200) z2 Can't find UID admin After experimenting a bit, I noticed that when I run ./start it deletes the 'inituser' file at some point during opening and mounting the database (as it appears anyway). So a few seconds later it looks for admin and finds nothing. Am I doing something wrong here? I have successfully done the whole thing in Windows 2000 (which of course is a different story, but still) and I can't find anything in the documentation that I'm doing wrong. I downloaded the zip file again and did the whole thing from the beginning and it made no difference, so it is not a corrupted file or anything like that. Can anyone help me on this? Thanks! Yannis P.S: And sorry for the huge email, I just thought that nobody can really help unless they have some details... --------------------------------- Do you Yahoo!? Yahoo!

You can define INSTANCE and SOFTWARE_HOMES in the start up script. See the section in the Zope Book. Please see the Zope book, http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/InstallingZope.…, "Environment Variables that Effect Zope at Runtime" And please keep this on the list, oher people may have the same question. -- Andy McKay

Since Transience is an external product, I'd have to extend it externally. Hmm, I wish that was documented in "The Zope Book" :-/ It's also be somewhat "challenging" to implement a keys method--the only thing I can think of is to extend the notify on add or delete methods to do housekeeping on the keys before actually doing the user defined functions for notify on add or delete. Sounds like a lot of work in comparison to just adding an already existing keys method to the API. I really don't want to have to manage a patch unless it's added to Zope :-/ Best Regards, -jj -- Hacker is to software engineer as Climbing Mt. Everest is to building a Denny's there.

Can I choose my python installation?
by Micheál Healy 06 Mar '03

06 Mar '03

Hi, If I have python installed on my PC, can I use that installation instead of that installed with Zope? The reason is that I am having trouble installing the win32 library for python on the Zope python instance. It fails to load pywise32.dll(?). I'm using a Win98 machine. TIA, Micheál Micheál Healy Engitech Ltd. 01 6204 516

Html2pdf problems
by Mehmet Yousouf 06 Mar '03

06 Mar '03

Hello all, I'm trying to generate a page to print and felt the best way is to convert it to pdf format. The information is on a database (mysql) and when I use <dtml-in printinfo> in the page, it renders the dtml page ok and by putting /html2pdf at the end of the url, it creates the pdf file. However, if the dtml-in command is passed a variable (<dtml-in "printinfo(nameid="SESSION['nameid']">), the dtml form renders fine but the pdf file will not be generated by it. I have tried sorting after the dtml-in command but the same story, even doing a <dtml-var "SESSION[nameid']"> while zope renders it, will not get converted to pdf..... if I save the file and use hmtldoc -f nameid.pdf nameid.html --webpage, it works. Any suggestions how I can resolve this problem? Regards, Mehmet

odbc da for zope on linux
by andy 06 Mar '03

06 Mar '03

Hi, Am I right in syaing that there is no such DA for zope running on linux? I can find the DA for the win platform, but can't find an equivalent for Linux..... I need to access information in an Access copied on a Linux server (where zope will also be running). All the clients connected to the server are Win98, so can't run Zope as a service anywhere else. Not sure if there's a problem with accessing data from this db if it's on the Linux server - if there is then I'll just point the DB request to one of the network machines. But first I need to get an adapter that works, and so far I can't see one. Andy

XML
by D. Rick Anderson 06 Mar '03

06 Mar '03

What is the best way to parse XML with Zope? I've been digging all over the site, and the docs there keep talking about adding an XML Document, but that option doesn't exist on my Zope server (2.6.0 on RH 8.0) and I can't find anything indicating that there needs to be a product installed. Simply put, I want to be able to grab an XML document with webclient() and be able to parse the contents of the XML using DTML. TIA Rick

Calling DTML document from a string/query
by Jan Maška 06 Mar '03

06 Mar '03

Hi all, Though it may seem as a stupid question, it's rather important (at least for me).. How to create a DTML document pointer (<dtml-var required_document>) from a string? Let's see this example: www.mydomain.com/somepath/index?read=20030220 What I need is that the index at somepath opens another document called '20030220' and prints it's contents, like in this case: ==index== <dtml-var standard_html_header> <dtml-var "20030220"> <dtml-var standard_html_footer> ===end=== only I want to be able to define this dynamically based on the user queries. If you can give any hints, it would really be helpful. -Mac =============================== Jan Maska, web developer Systinet, Prague(CZ) jan.maska(a)systinet.com tel.:(+420)608453492 visit http://www.systinet.com ===============================
