Don't do that ;-) More helpfully: The above if very fragile and unsightly. Rather than doing a redirect to get back to your form, just return it at the end of your validation script, should the values not be good enough: return context.myForm() ...that way you'll still have the original request and won't need ot do any nastiness to pass values around. cheers, Chris

startup exception
by baiewola＠netscape.net 13 Aug '02

13 Aug '02

I just installed Zope 2.5.1. It installed alright and seemed to be running okay. I did some other installations for Fink and MySQL, then I went back to Zope to change the default startup switch from -D to -Z '' and now it something strange happens. It seems to start up but a few seconds later it spits out this line: [1] Done ./start If I look at the running processes immediately after startup up Zope (and before receiving the "done" message), there is a z2.py process running for a few seconds. I thought maybe I screwed up the start file, but changing it back to -D didn't work, so I started Zope up myself from the command line, like this: myuser% /usr/local/bin/python2.1 /Applications/Zope/z2.py -D And I received a startup exception that I don't understand: ------ 2002-08-13T12:06:26 INFO(0) ZODB Opening database for mounting: '12691952_1028915609.880719' ------ 2002-08-13T12:06:26 INFO(0) ZODB Mounted database '12691952_1028915609.880719' at /temp_folder ------ 2002-08-13T12:06:27 PANIC(300) z2 Startup exception Traceback (innermost last): File /Applications/Zope/z2.py, line 558, in ?

Problem with undo
by Josef Meile 13 Aug '02

13 Aug '02

Hi, since I installed the newest-stable Zope version (2.5.1) under Linux Susse 7.3, I have had problems when I click on the "undo" tab of the "manage interface". Sometimes it takes a long time to show me all the transactions that I can undo. On the while, it blocks Zope. So, people who is visiting the site can't see it till this is done. Often they will see the common error message that browsers show when they can't load the page. Is there any way of solve this problem? What are the causes? Thanks in advanced, Josef.

Lookinf inside page templates from a script
by Felix Ulrich-Oltean 13 Aug '02

13 Aug '02

Hi I'd like to get the names of all the macros in a pt and of all the slots within each macro, but I'm getting guarded_item errors. In PageTemplate.py, I have found pt_macros(), which returns a dictionary with macro names as keys. Great so far. I can even print pt_macros() and get a string representing the whole dictionary. However, when I try to access the corresponding value so I can look for the slots inside each macro, I get the error shown below. Is there a way of gettting the macros and their slots from a script, or do I have to write an external method / product? Thanks Felix. Error Type: TypeError Error Value: unsubscriptable object Traceback (innermost last): File /usr/local/Zope-2.5.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /usr/local/Zope-2.5.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 114, in publish File /usr/local/Zope-2.5.1-linux2-x86/lib/python/Zope/__init__.py, line 159, in zpublisher_exception_hook (Object: Playground) File /usr/local/Zope-2.5.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 98, in publish File /usr/local/Zope-2.5.1-linux2-x86/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: examineMacros.py) File /usr/local/Zope-2.5.1-linux2-x86/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: examineMacros.py) File /usr/local/Zope-2.5.1-linux2-x86/lib/python/Shared/DC/Scripts/Bindings.py, line 252, in __call__ (Object: examineMacros.py) File /usr/local/Zope-2.5.1-linux2-x86/lib/python/Shared/DC/Scripts/Bindings.py, line 283, in _bindAndExec (Object: examineMacros.py) File /usr/local/Zope-2.5.1-linux2-x86/lib/python/Products/PythonScripts/PythonScript.py, line 302, in _exec (Object: examineMacros.py) (Info: ({'script': <PythonScript instance at 8b76cd0>, 'context': <Folder instance at 8aeb7e8>, 'container': <Folder instance at 8aeb7e8>, 'traverse_subpath': []}, (None,), {}, (None,))) File Script (Python), line 8, in examineMacros.py File /usr/local/zope/lib/python/AccessControl/ZopeGuards.py, line 90, in guarded_getitem (Object: pt_macros) TypeError: (see above)

Question regarding exUserFolder
by low kian seong 13 Aug '02

13 Aug '02

I have a problem with exUserFolder. I have created a webpage which contains links to another wepage, the latter which is protected by exUserFolder and restricted to Authenticated Users only. For example this is my link: www.webpage.com/to_restriced?arguments If the user is not logged in then he / she will be directed to the login page in exUserFolder. The problem I am having is that exUserFolder doesn't preserve the arguement of the orginal address. Is there anyway for it to be preserved ? -- Get your free email from www.linuxmail.org Powered by Outblaze

What is lst[0] ??
by Nicolas Évrard 13 Aug '02

13 Aug '02

Hello, Since I wanted to have only the 5 last entries of a folder containing news, i did this little script and used it in a ZPT : sorted_lst = sequence.sort(lst, (('date', 'cmp', 'desc'), ('titre', 'nocase', 'asc'))) if len(sorted_lst) <= 5 : return sorted_lst else : return sorted_lst[0:5] It works well, I've got what I want ... But I wonder why should I use sorted_lst[0:5] to have 5 elements since there is in fact 6 elements in it ?? I suppose sorted_lst[0] is some kind of a dummy element to stock some informations ... Am I right ? -- (°> Nicolas Évrard / ) Liège - Belgique ^^

Hi all, I have installed a Gentoo server, running Python 2.2. Since Zope 2.51 won't run with this version of Python, what should I do? Installed Zope 2.6 or running 2 versions of python on the same server (if that is possible...)
