Zope Questions

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greets. I'm (slowly) learning Zope, and loving every bit of it, but have run into a few snags. I'm quite comfortable with PHP, which I know is the source of a lot of my problems as Zope and PHP are two entirely different paradigms. There's just so much information on the Zope website, that I'm having a difficult time finding the answers to certain problems, which unfortunately have left me in somewhat of a quagmire. Can someone point me to the location where I might find more information on the following, with regards to Zope: - Variable Passing through GET request Here's what I'm trying to do: I'm trying to create a "tool-tip" (which is actually contained in a frame) and would like to pass a parameter to the DTML document which contains the HTML, etc. for the tool-tip. Something like: <a href="show_tip?a=b&c=d"> Q: Is there a magical Zope variable that contains the arguments passed on a GET URI (as in PHP?) Q: Must any variable be declared first? - "case" statement Q: Does there exist the equivalent of a shell "case" statement in Zope? (This is in line with my previous questions). Thanks in advance. Any help would be greatly appreciated. - -- George M. Ellenburg <george(a)ellenburg.org> <http://www.ellenburg.org/> 3 Years and counting of being 100% Microsoft-free; and much more productive.

Hi, I am trying to install Zope251 on a cobalt raq3. Bin version appears to install Ok. However when I try to install MySQL-python 0.9.1 the product is broken because _mysql.so is looking for GLIBC_2.2 Can anyone suggest a fix. Cobalt 3s are based on redhat 6.0 which uses GLIBC_2.1 Any suggestions? Sorry if this is a bit off subject Thanks Dave

Hi All, The operational error problem was solved, actually the problem with MySQL database, so I reinstalled MySQL using rpm, now it is working with MySQL.

Hi Yesterday we upgraded from Zope 2.4.0 to 2.5.1 (binary release, python 2.1, win32-x86), python 2.1.3, win32) ZServer/1.1b1 and now, I cant access some folders, error is always the same: Error Type: SystemError Error Value: Failed to import class atoi from module ZPublisher.Publish Traceback (innermost last): File D:\Zope\website\lib\python\ZPublisher\Publish.py, line 150, in publish_module File D:\Zope\website\lib\python\ZPublisher\Publish.py, line 114, in publish File D:\Zope\website\lib\python\Zope\__init__.py, line 159, in zpublisher_exception_hook (Object: Gabriel) File D:\Zope\website\lib\python\ZPublisher\Publish.py, line 98, in publish File D:\Zope\website\lib\python\ZPublisher\mapply.py, line 88, in mapply (Object: manage_main) File D:\Zope\website\lib\python\ZPublisher\Publish.py, line 39, in call_object (Object: manage_main) File D:\Zope\website\lib\python\Shared\DC\Scripts\Bindings.py, line 252, in __call__ (Object: manage_main) File D:\Zope\website\lib\python\Shared\DC\Scripts\Bindings.py, line 283, in _bindAndExec (Object: manage_main) File D:\Zope\website\lib\python\App\special_dtml.py, line 172, in _exec (Object: manage_main) File D:\Zope\website\lib\python\DocumentTemplate\DT_In.py, line 637, in renderwob (Object: objectItems) File D:\Zope\website\lib\python\DocumentTemplate\DT_In.py, line 763, in sort_sequence (Object: objectItems) File D:\Zope\website\lib\python\ZODB\Connection.py, line 472, in setstate SystemError: (see above) I've been able to track the error to the SQLMethods contained in the folder.

Only old SQLMethods are afected (objects converted from 2.4 to 2.5); new SQLMethods work fine. Gabriel Genellina Softlab SRL

Zope newsgroup?

Hi folks, is there a zope newsgroup out there in usenet-land? This mailing list is getting quite a bit of traffic, and I think it would be easier to organize in a newsgroup or two.

I think its a problem with acquisition and traversal: I haven't managed to find a way to 'set' the absolute_url so that Zope really gives me the object I want rather than it resolving the object by working down to the root to get the index_html then working back up until it gets the first object with the name.... I remember seeing in section 1.3 of chapter 3 of Dieter Maurer's (excellent) book http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html an explanation of why your problem occurs. What happens if the user tries to create an object whose id already exists? Does this raise an error anyway? If this raises an error couldn' t you trap this error and get the user to try again, rather than trying to check if it doesn' t exist? Getting the zen out of zope is certainly painful....and i'm hundreds of miles away yet...

This mailing list > is getting quite a bit of traffic, and I think it would be easier to > organize in a newsgroup or two. You might think that, I disagree. But then, I read comp.lang.python via the mailing list. I think this has come up on a number of occasions, and no-one's volunteered to do the work to get the newsgroup created. I know I don't read usenet at all (except, as noted, for some that are gatewayed to/from email) and I suspect I'm not the only person on this list that wouldn't bother with the newsgroup.
