How to get "context" in an instance method
by Paul Tiemann 06 Mar '02

06 Mar '02

This probably has a simple solution, but I'm probably going to have to sleep on it to find it. Thanks in advance for any help... I have a class derived from ObjectManager and SimpleItem.Item which defines a directory structure under it. Something like this: class MyZopeProduct( ObjectManager.ObjectManager, SimpleItem.Item ) # ... def myFunc(self, context=None, REQUEST=None): doSomethingWithContext(context) After I add an instance of MyZopeProduct to my root folder (as myinstance) I can go to http://me:8080/myinstance and things work as expected. If there is a folder inside my instance called 'folder' then I can also go to http://me:8080/myinstance/folder and everything works fine. What I can't figure out is how to go to http://me:8080/myinstance/folder/myFunc and have the context (the folder instance object) passed into my script. I've been hunting through the source for something similar but I can't find it. It's probably something simple, but I just can't seem to find how to get the context. When I call myFunc the REQUEST variable is inserted, but the context always comes back as None. All other Acquisition-related functionality seems to work for "folder", like pulling 'index_html' out of the root because it doesn't have one of its own (and neither does "myinstance") I want to be able to use Acquisition within my Python Product code... Is it possible? Thanks in advance! -Paul _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

ZCatalog "AttributeError: __call__" error
by Villemin, Remi 06 Mar '02

06 Mar '02

Hello, I am running Zope 2.5.0. I am able to create a ZCatalog in some folders and to "Find and Catalog" objects in it, but in some other folders when I try to "Find and Catalog" objects I get an "AttributeError: __call__" error. Does anybody has an idea where this error comes from? Thanks a lot, Rémi ============================== The error log is: catalogObject File /usr/local/zope/2-5-0/lib/python/Products/ZCatalog/Catalog.py, line 423, in recordify AttributeError: __call__

ZSQL with REQUEST and named arguments
by Ulrich Wisser 06 Mar '02

06 Mar '02

Hello, my ZSQL method has several arguments. Some values will be provided via the REQUEST object and some do I want to hardcode in the method call. REQUEST will have a key 'name' (which is the name I want to retrieve from the database) and I want to search only in zip area "50xxx". <dtml-let results="sql.address(_.None,_,zip='50%')"> If I use this call the name from REQUEST.name will never be used by the ZSQL method. If I do <dtml-call "REQUEST.set('zip', '50%')"> <dtml-let results="sql.address(_.None,_)"> Everything works fine. Any ideas? How can I make this work without the dtml-call statements (seems ugly to me).

Problem?? ZServer Monitor Server doesn't start
by addyd＠unk.edu 06 Mar '02

06 Mar '02

After having problems keeping 2.5.1b1 up I deleted the folder and installed 2.3.3. After running the ./start script I get the ZServer starting on port 8080 message, and the ZServer FTP Server starting on port 8021 message, and the ZServer PCGI Server starting with Unix socket message. Following that I SHOULD see: ----- 2002-03-05T15:03:33 INFO(0) ZServer Monitor Server (V1.5) started on port 8099 (and I'm assuming, a return to the command line. Instead it seems to hang there.) Zope is running, as I am able to see the management screen, etc. Is this a problem? If so, is there a way to track down the source of problem and fix it?

zope as win32 service and stupid_log_file
by Cornelis J. de Brabander 06 Mar '02

06 Mar '02

Did anybody succeed in activating that STUPID_LOG_FILE when running zope as a win nt service? Creating a environment variable does not help. I can understand that because this would result in a conflict when running two versions of zope on the same machine. So there would have to be a environment variable that is bound to a specific service. zope 2.4.3. python 2.1.

NT Service doesn't respond on stop request
by Mark Snellings 06 Mar '02

06 Mar '02

I have Zope 2.4.2 running as service on Windows 2000. The service starts okay, but when I stop it from the Management Console, the service stops and then about a minute later I get the message "Could not stop the Zope (WebSite) service on Local Computer. Error 1053: The service did not respond to the start or control request in a timely fashion." If I enter the "NET STOP WebSite" command from a command window, the service stops and the command completes without any error messages in about 20 seconds. Any idea why I'm getting the error message when stopping the service from the Management Console? Thanks Mark Snellings

renamed gadfly DA, ZSQL Method shows new name, when called looks up old name
by hans 06 Mar '02

06 Mar '02

On Zope 2.3.2 created gadfly DA, then created a ZSQL Method, then renamed my Gadfly DA. In ZSQL Method Zope shows me the new name as connection id, but when i call it (programmatically), Zope complains The database connection old_name cannot be found. ? Is this a bug or a feature, and why so? furthermore, whenever i looked into the Gadfly DA/Properties, zope showed me "demo" as data source (alphabetically first), although the DA takes *my* database as data source. Very misleading. ? Is that known and is there a higher version where this is fixed? -- ------------------------------------------------------------- Who's got only a hammer sees the world as a nail hans augustin (software developer) hans(a)beehive.de beehive elektronische medien GmbH http://www.beehive.de phone: +49 30 847-82 0 fax: +49 30 847-82 299

Adding CookieUserFolder Programmatically
by Zahid Malik 06 Mar '02

06 Mar '02

Hope someone can help: I'm trying to add a CookieUserFolder programmatically either with dtml or python and I'm no expert! I'm using Zope 2.5.1b1. After looking through all the source for CUF I still can't create a CUF. Just for testing I've created an external method which does this: from Products.CookieUserFolder.CookieUserFolder import manage_addCookieUserFolder def zcreate( self ): manage_addCookieUserFolder( self ) This does do something but unfortunately it locks me out of the folder that I create a CUF into and therefore I can't tell what happened. Also I don't know how to add/edit/delete CUF users in python or dtml which I really need to do. Any help very very gratefully received. Thanks Zahid -- -------------------------------------------------------------------- Dr Zahid Malik Tel: +44 (0) 20 7594 6336 Research Fellow Fax: +44 (0) 20 7581 4419 Dept. of Electrical Eng.

Z_REALM Problems
by abg＠comco-inc.com 06 Mar '02

06 Mar '02

I'm setting Zope up on a new server running WindowsNT. When I change the Z_REALM environment variable, nothing happens. Zope ignores it completely. Yes, I've rebooted. I've set up several Zopes, and never before had this problem (though, my previous experience is with Win2000). Has anyone else encountered this? Any fixes? Here's my Zope info: Zope Version (Zope 2.4.3 (binary release, python 2.1, win32-x86), python 2.1.0, win32) Python Version 2.1 (#15, Apr 16 2001, 18:25:49) [MSC 32 bit (Intel)] System Platform win32 Thanks, Aaron Gillette abg(a)comco-inc.com
