One time persistent variable
by Antonio Beamud Montero 05 Dec '02

05 Dec '02

Hi all: How I can make a variable from a Product persistent, but only exists a copy in the ZODB?, i.e. this variable is updated every 30 sec. and I don't want ZODB saves all old states of this variable, only the last... How I can make this...?

RE: [Zope] Problem running Zope on Windows 2000

Thanks Andy for your help on this - the problem was in the registry. There was another registry setting ..\Services\<servicename>\Parameters\Start that was not being set by the installation process (the Start parameter had retained the default directory information for python.exe). I re-installed Zope using the default settings and everything works ok.

objectValues return value
by David Bear 05 Dec '02

05 Dec '02

I wrote a script the returns a list object of all title_or_id values of objects in a folder. The problem is when there are no objects in the folder. The script should return a list contianing the string 'none'.. but doesn't. In fact, the script seems to either hang or have no return value... Any pointers? # returns a python list contained the title of the page templates in this folder list = context.objectValues('Page Template') if list == None: return ['none'] newlist = [] for zpt in list: newlist.append(zpt.title_or_id()) return newlist -- David Bear College of Public Programs/ASU Mail Code 0803

Problem running Zope on Windows 2000
by Jerry Leeson 04 Dec '02

04 Dec '02

I have installed Zope 2.6 in a Windows 2000 environment and the Zope service will not work. In the event log I get the following error: The instance's SvcRun() method failed File "C:\INETPUB\wwwroot\TESTZOPE\bin\lib\win32\lib\win32serviceutil.py", line 601, in SvcRun self.SvcDoRun() File "C:\INETPUB\wwwroot\TESTZOPE\ZServer\ZService.py", line 181, in SvcDoRun self.start_zserver() File "C:\INETPUB\wwwroot\TESTZOPE\ZServer\ZService.py", line 203, in start_zserver None, None, 0, 0, None, None, win32process.STARTUPINFO()) pywintypes.api_error: (3, 'CreateProcess', 'The system cannot find the path specified.') Is there some sort of path setting that is not being set during the install? Alternatively, I could try to use IIS or Apache webserver but the administration guide does not seem to be available yet to tell me how to do so. Any ideas would be greatly appreciated.

I'm wondering what folks are using/recommending for managing membership on a Zope/CMF/Plone site. I don't have any sort of external membership sources to deal with. thanks, Danny

ZClass inheritancs:propertysheets
by Patrick Stinson 04 Dec '02

Am I now corrent in assuming that ZClasses do NOT inherit property fields from their super-ZClasses? if not, how do you access the inherited propertysheets, instead of the actual property sheets.
