Hello, you may want to take a look at this doc: <http://www.zope.org/Members/AlexR/ZClassIDBug> This looks like the ZClass ID bug problem.

Re: getting object reference from an id string?
by Alexandre Ratti 09 Mar '00

09 Mar '00

Hello Darran, building on Rik's previous answer, how about this: <dtml-call "REQUEST.set('myObjRef', _[desired_id])"> It tested OK with an Image object called "image" and located in the site root: # Storing the image name in a variable <dtml-call "REQUEST.set('desired_id','image')"> # Creating an object reference based on the variable <dtml-call "REQUEST.set('myObjRef', _[desired_id])"> # Displaying the object title and size <dtml-var "myObjRef.title"> <dtml-var "myObjRef.getSize()"> # Rendering the object if it's renderable. An image is. <dtml-var myObjRef> If it's not renderable, you'll end up with something like "<Folder instance at 01368880>" in the HTML page source code. Does it work for you? If yes, you may want to add a FAQ Question and it's Answer on zdp.zope.org (hint, hint :-). Cheers.

<dtml-var aaa> vs. <dtml-var "aaa"> question
by Michael Lausch 09 Mar '00

09 Mar '00

can anybody explain me why the following is happening: if i have a DTML Method m1 in the folder f1/f2/m1 and i write <dtml-var f1.f2.m1> this does not work. AFAIK the `.' operator needs to much priviledges in this context. <dtml-var "f1.f2.m1"> works, but the DTML output is not rendered, but displayed as text like: <standard_html_header><h2>........ so i'm using this construct for now: <dtml-with f1> <dtml-with f2> <dtml-var m1> </dtml-with> </dtml-with> My question is why's <dtml-var "f1.f2.m1"> not rendered?

newbie tree q - how collapse and expand
by Andy Heath 09 Mar '00

09 Mar '00

I'm getting better but stil learning. I want to collapse/expand a tree at will so that I can come in from particular hyperlinks to a known tree state. I know there are two variables I can set but I don't know how to do this from code. For example how could I have a hyperlink whose HREF is a page containing a tree in such a way that when you get there the tree gets collapsed while another link to the same page doesn't collapse it. Can someone show me some code that dows this please.

RE: [Zope] RE: [newbie] MySQLDA Installation error at MySQLdb bui ld.
by Carlson, Christopher W. 09 Mar '00

09 Mar '00

I've never used Caldera's distribution, but if it's anything like Red Hat, the following should work: 1) Open /etc/ld.so.conf with your favorite text editor and append the directory in which libmysqlclient is located. 2) Run 'ldconfig' This will update the list of directories that the linker searches. Let me know how it goes. --- Chris -----Original Message----- From: Eric L. Walstad [mailto:ewalstad@energywright.com] Sent: Wednesday, March 08, 2000 12:06 PM To: CURTIS David; Chris Best; zope(a)zope.org Subject: [Zope] RE: [newbie] MySQLDA Installation error at MySQLdb build. Dave & Chris, Thanks for replying. I'm running Caldera OpenLinux 2.3. I chose it because I heard that it had one of the smoothest installations. I am only a few months into Linux; I'm transitioning over from the Dark Side (Microsoft). Heehee. Here's my best guess at what's going wrong with the MySQLDA/db installation. I think it is related to access rights or locations to the libmysqlclient.so.6 file. When I run build.py, I can see the script accessing the MySQL library folder (in my case: /usr/local/lib/mysql) This is the path the MySQL 'make install' script displayed when it was done installing MySQL. I checked, and the library files are there. Anyway, I can see the build.py script working some of its magic within this folder, so I feel confident that the paths in the Setup.in file are correct. However, it is crashing when it tries to "from _mysql inport *". I am not (yet) a Python programmer, so I don't understand the implications of this import. I'll reprint the error message I received for anyone else that reads this: Traceback (innermost last): File "build.py", line 14, in ? import MySQLdb File "MySQLdb.py", line 19, in ? from _mysql inport * ImportError: libmysqlclient.so.6: cannot open shared object file: no such file or directory" I like your idea of making a link to the MySQL library file (libmysqlclient.so.6). I know this is a stupid question, but if I run: ln /usr/local/include/mysql libmysqlclient.so.6 what will the link be called, and where will it be located? How will this help the build.py script? Thanks again for your input! Chris, This seems to be pretty common which makes me feel, well, not alone... Thanks for the note and I'll keep you updated on my progress. Here's what Dave Curtis sent me earlier today. He reinstalled EVERYTHING and it worked, but I'm not ready to go that far yet. Maybe something in here will help you... +++++++++++++++++ Eric, Major bummer! Installing ZOPE with MySQL is not as easy as it could/should be. I wish one of the programmers would clear up this Zope/MySQL confusion. I wonder if Alanprog could help out by simplifying the installation. As I am a newbie I would love to fix it but it way over my head. Ok, about your problem, this is where I also got stuck. Here is my solution. I reinstalled linux (probably didn't need to but I did) I used an older version of MySQL ver 3.22.27 and installed ZOPE, PYTHON, MYSQL from the source. I made sure that I also installed the python development stuff. I then used the the same procedure and viola the darn thing worked. Can't tell you anymore. Well, use can try using a link # ln /usr/local/include/mysql libmysqlclient.so.6 and see if it can now find the libraries/files it needs. Are you sure that the Setup.in path is correct? I looked at both these files build.py and MySQLdb.py they both refer to libraries and their respective location. Anyway good luck and if you get an answer, please let me know also. I am curious what O/S your are using and why you choose it. I probably going to change over to mandrake linux for security reasons.

I am currently using them with the ZMySQLDA version 1.1.3, along with MySQLdb version 0.2.3. There is a very good howto on installing these. I have recollections of compile problems on my first attempt, but it turned out I was tryring to compile something that was obivated by MySQLdb. So, follow the instructions carefully. -- Have a better one, Curtis. <dtml-var standard_work_disclaimer>

Multiple paths to same documents
by Flemming Funch 09 Mar '00

09 Mar '00

I'm new with Zope. One thing I'm looking for how to do is the effect that one document might virtually be stored in multiple folders. For example, if I keep a hierarchy of folders that is an archive of articles, maybe stored chronologically in a folder for each month or something like that. But then I also want those same articles to appear in other folder hierarchies, categorizing and organizing them in various ways. And I don't just want to put duplicates of the document in there. I'd like that if somebody updates the original, the virtual documents in the other folders update too. Is there some obvious DHTML statement or trick I don't know about yet? Or a Product that does something useful about this? Essentially I'm looking for an equivalent to symbolic or hard links to files in a Unix file system. - Flemming o / \------------------ Flemming A.

For example, a person is browsing a site that uses a dtml tree for navigation and I want to change the icon for the node to a different icon (say, that shows a checkmark) when they have visited the page (or interacted with it in some way). what would be the best way to do this? ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
