Hello Zopers, I have some .swf files got into my Zope db via ftp and their mime type has been set by Zope to "application/octet-stream" while it should be "application/x-shockwave-flash" I reset them manually bur how can I edit the associations between the file name extensions and the Zope mime types so that Zope automagically sets the correct value? Thanks anyone will help me Catonano

RE: Installing PIL on binary dist. of Zope 2.6.1 on Linux...

Hi, I have found the document to install PIL on zope at http://www.zope.org/Members/regebro/PIL_zope Followed instructions, worked fine. Did copy file _imaging.so and the PIL directory to my zope/lib/python. When starting zope I get 2003-03-04T09:51:31 ERROR(200) Zope Could not import Products.ZPhotoSlides Traceback (innermost last): File /home/zope-2.6.0/lib/python/OFS/Application.py, line 541, in import_product File /home/zope/lib/python/Products/ZPhotoSlides/__init__.py, line 13, in ?

Finding owner of an object
by Tom Emerson 04 Mar '03

04 Mar '03

Greetings, I have a folder of files (think the FileLibrary example), where files may be owned by different people. In a ZPT I would like to limit the set of files that are displayed to those owned by the current user. I can't find a way to get the owner of a given object: what am I missing? For example, I use container.Submissions.objectValues('File') to get the set of files in the Submissions folder. Is there a method I can call on each File object to get its owner?

Getting metatype information
by Fearless Froggie 04 Mar '03

04 Mar '03

Hi, If I have an address such as the following: an_address = context.REQUEST['URL2'] How would I get the metatype of the object "an_address" is pointing to? I have the feeling that it shouldn't be too difficult, but I just can't seem to wrap my head around it! Many thanks, Rita. __________________________________________________ Do you Yahoo!? Yahoo!

plone problem
by David Bear 04 Mar '03

04 Mar '03

just installed plone. I unzip/tarred it and put symlinks in my Products directory to all the CMFPl* folders created by tar. However, there are problems. Here's the traceback printed with zope starts. The error's don't appear critical as zope is still running. I just haven't created in plone objects yet. Any advice? ================================ 2003-03-03T15:41:53 ERROR(200) Zope Could not import Products.ActivePak Traceback (innermost last): File /home/httpd/zoperoot/lib/python/OFS/Application.py, line 541, in import_product File /home/httpd/zoperoot/lib/python/Products/ActivePak/__init__.py, line 2, in ?

NuxUserGroups and CMF not working
by baiewola＠netscape.net 04 Mar '03

04 Mar '03

I installed NuxUserGroups, but the product was broken. The traceback error said "No module named CMFCore.CatalogTool." I presumed that I had to install CMF, so I did. After installation, CMFCore, CMFDefault, and CMFTopic appear in my products list unbroken, but I can't create a CMF Site object (it should be in the pulldown menu, right?). And NuxUserGroups is still broken. The weird thing is that I now have the option of giving local roles to groups -- I just can't create the groups. * For CMF, is it mandatory that Zope be installed using /var/zope as my INSTANCE_HOME and /usr/local/zope/ as my SOFTWARE_HOME? * If that's the problem, what do I need to change about CMF to make it work with my own installation?

RE: [Zope] Zope Installation Problems

You might have better luck if you use a source install of Python 2.1.3, and compile the source install of Zope 2.6.1 with the specific python2.1 binary you installed from source (wherever you installed it). Sean -----Original Message----- From: Sheppard Norfleet [mailto:shepnorfleet@comcast.net] Sent: Monday, March 03, 2003 5:29 PM To: zope(a)zope.org Subject: [Zope] Zope Installation Problems I am using Rad Hat Linux 7.x. which comes with python 2.2 not the problem. I have Zope that has a python 2.1 one with it. when I try to build w_pcgi.py using the python that comes with zope, I get compile errors when trying to build the exception modules, the last message has a message like "I and PICKY raiseError" There are a ton of warning and a few errors sprinkled in a compiler output (or at least it looks like that). Anyway I have been working at this installation for about a week, I have tried a source install and binary install. No matter which way I go zope fails to build using the 2.1 python that comes with it. Has anyone else had these problems? Trying to run Zope like this: bin/python z2.py -p /usr/local/apache/cgi-bin/zope.pcgi all I get in return is a new bash prompt wiht no warnings. the log files are empty or don't exist. Please help! BTW, don't mean to knock mailing lists but wouldnt forums be a lot easier way to communicate? Just a thought...

RE: [Zope] Supported Processor for Zope

x86 hardware is usually fastest, compared to other platfoms. YMMV. Best test is likely to run Python's pystone tests on whatever hardware you might be evaluating; any score on new hardware over 20,000 is good. Athlon, p4, and Xeon are likely your best bet. run like this (in Debian GNU/Linux, for example): /usr/bin/python2.1 /usr/lib/python/test/pystone.py Sean -----Original Message----- From: McDonnell, Larry [mailto:lmcdonnell@protonenergy.com] Sent: Tuesday, March 04, 2003 6:40 AM To: Dennis Allison; McDonnell, Larry Cc: 'Zope@Zope.

As long as the needed OS support, Python, and a suitable C/C++ compiler are there, you should have no problem. _______________________________________________ Zope maillist - Zope(a)zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev ) _______________________________________________ Zope maillist - Zope(a)zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Re: [Zope] Extending Zope system code without editing

How do I modify a class defined in lib/python/StructuredText >or lib/python/ZPublisher or the like with the minimum of fuss and without >patching the actual distributed Zope system code... If you're looking for a way to change the behavior of an object without making *any* changes to the source code, I'm pretty sure that subclassing is all that's available. It is possible to define objects such that they allow certain methods to be overridden by ZMI objects, but that is special behavior that must be explicitly provided in the product. For my money, inheritance is about as low-impact a mechanism as one can hope to find. Unless I'm not understanding what you're trying to do or what issues this approach raises... in which case, let me know. If the major stopping point here is concern about hosing Zope, there are several things you can do to mitigate the potential harm: 1. Work on a test installation 2. Use comments liberally 3. Use a tool like rcs or cvs to provide version control 4. Refine your technique on a trivial product like Boring There's no better way to learn how Zope really works than to rip into the source. My advice would be to go for it. HTH, Dylan

Inheritance is probably your answer here. You can either subclass an existing object or mix your code into an existing object's definition. Say you want to add a method to a Folder. One way is to make a basic product called my_folder, mix in Folder as a base class and then start overriding and extending. Then, in the ZMI you'll have the option of whether to use a standard Zope folder or one of your custom Folders. On the other hand, you could create a Python module called my_folder_changes, create a simple class called my_folder and use it to define the behaviors you want to see. Then add your class to the *front* of the list of base classes inherited by Folder. This won't override anything actually defined in Folder's class definition... you'll need to comment those out to override them with this technique. Is that what you're looking for? HTH, Dylan
