I am a real Zope newbie so bear with me. I am attempting to re-setup an ODBC connection in Zope (that used to work until a fatal hard drive failure) to access a Visual FoxPro database and get the following error: sql.error: ('S0002', 173, "[Microsoft] [ODBC Visual Foxpro Driver]File 'users.dbf' does not exist.") There are multiple tables and it cannot find any of them. The database connection within Zope shows it is open successfully. Particulars: NT WS 4.0 SP3 Zope 2.2.4 ODBCDA Visual Foxpro database is on a Novell 4.11 server As I stated above, this used to work until the hard drive blew and I had to reload NT and Zope and reloaded the data.fs file from the backup. It turns out only the data.fs file was being backed up nightly. The database connection says it is open, but we can't process any queries. Thanks for any assistance. Mike McConnell

problem saving file twice using ange-ftp
by John Hunter 09 Apr '01

09 Apr '01

I am using ange-ftp in GNU emacs to edit my Zope ZWiki pages. This works fine, but when I try and save a page for a second time, I get the error Opening output file: FTP Error: "426 Error creating file.", /myuser(a)nitace.bsd.uchicago.edu 8021:/Wikis/April/FrontPage If I kill the buffer and then reenter it again, I am allowed to modify and save it only one time. Any suggestions about what is going wrong and how to fix it? Thanks, John Hunter Zope 2.3.0 GNU emacs 20.7.1 python 1.5.2

Recently, someone reported improved error messages for "FTP" save (he put his patch into the Collector). As I understood the announcement, syntax is checked and problems reported the same way as for ZMI. There is a proposal how non-standard object types can be created. I think, there is even an implementation around. Saw recently something in a mailing list (think "zope-dev"). Versions are implemented by cookies. FTP and WebDAV do not support cookies, but it would not be difficult to use the built-in product SiteAccess (more precisely, its AccessRule) to map folders to cookies; e.g. /Version/<version>/<url> would set the cookie for <version> and then access <url>. This way, it could be used easily be FTP. I am not sure about WebDAV, as it uses the source port and I am not sure whether AccessRules are executed for these traversals. But I think, there is a good chance. Dieter

Your instances are not images but collections of three images. I would expect, they derive from an Object Manager not from an Image. Dieter

ZClass / BaseClass OFS:Image
by Stefan Mallepell 09 Apr '01

09 Apr '01

Hi I'd like to make a ZClass based on the OFS:Image Baseclass ... unfortunately I don't get it working. The basic Idee is to have a Object containing 3 Images (Thumbnail, Normal, Large) + some extra attributes like "shortdescription", "description". The object should know (in attributes) the size, high and width for all the images. Unfortunately as soon as I add the OFS:Image Baseclass I don't get a working ZClass ... And I haven't found a example with a zclass based on ZImage. All the other products I looked to (like JPicture or ActiveImage) isn't really helping. Is there anybody who can help me? I'm really desperate, cause it's bloody urgent ... Thanks a lot in advance. Kind Regards Stefan Mallepell

You are right: You do not understand "containment before context".

Using "ulimit -c 20000", you let Linux generate a "core" file (see the "bash" documentation for details about "ulimit"). You can then use "gdb" to see, where the segmentation violation occurs. If you are lucky, the problem will soon be hashed out. Dieter

Adding objects is usually protected by "Add <object>" while changing them is protected by "Change <object>" and object deletion by "Delete objects". Thus, you can separate creation (granted to "Anonymous") from changing (granted to "Owner" and "Manager") and deletion (same as for changes). Dieter

problem saving file twice with ange-ftp
by John Hunter 09 Apr '01

09 Apr '01

I am using ange-ftp under GNU-emacs to edit my Zwiki Web in emacs-wiki-mode and am encountering a strange problem. If I edit a page, I can save the changes *one time only*. After that, I get an error 426 from the ftp server: Opening output file: FTP Error: "426 Error creating file.", /jdh2358(a)nitace.bsd.uchicago.edu 8021:/Wikis/April/FrontPage Mark set [2 times] If I kill the buffer and reload it, I can again make changes to it 1 time, and get the error after subsequent save attempts. Any suggestions? Is this a version objects problem? Thanks, John Hunter Version info: Zope-2.3.0 python 1.5.2 GNU emacs 20.7.1
