I have tried to insert it with ..<dtml-var > Question1>..no error but it doesn't work as I expect,sir. Hi Pattreeya, I am sorry, I am not sure what tutorial this is. You can best ask questions like this on the Zope mailinglist: http://www.zope.org/Resources/MailingLists The collective wisdom of the community you reach through the Zope list reaches far bejond that of the Zope.org webmasters. I have copied this reply to that list as well. Hope this helps! -- Martijn Pieters | Software Engineer mailto:mj@digicool.com | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

by Lars Heber 15 Mar '01

15 Mar '01

I have been searching the list for a some hours now, but could not find a satisfying solution. All I wanna do is moving a ZClass (or simply a doc) from one folder to another programmatically. Could anybody give me a hint; please? Thanks. -- Lars Heber, mailto:Lars.Heber@t-systems.de T-Systems, debis Systemhaus GEI GmbH, Geschaeftsstelle Sachsen

IOERROR Uploading a file
by Richard Moon 15 Mar '01

15 Mar '01

Anyone had this ? I'm getting an IOERROR Errno 5 Input/output error when uploading a file to my zope site. The file is handled by an external method def abcfile_read(self,REQUEST): # following line reads each line from uploaded code file=REQUEST.form['abcfile'] and the error is occurring at the file=REQUEST.form['abcfile'] line Now this works fine on my development machine and it _did_ work fine at my hosts but now it doesn't (after updating the site and the external methods - but AFAIK not changing the file upload area). I did 're-edit' the external method on the management interface. Is it permissions ? Any clues where to start looking would be greatly appreciated. the form which is used for the input looks like <form ENCTYPE="multipart/form-data" method="post"> Abc file <input type="FILE" name="abcfile"> Here's the traceback <!-- Traceback (innermost last): File /home/sites/site7/users/tunedb/2-2-2/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /home/sites/site7/users/tunedb/2-2-2/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/sites/site7/users/tunedb/2-2-2/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /home/sites/site7/users/tunedb/2-2-2/lib/python/ZPublisher/Publish.py, line 171, in publish File /home/sites/site7/users/tunedb/2-2-2/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: AddAbcFileLogic.html) File /home/sites/site7/users/tunedb/2-2-2/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: AddAbcFileLogic.html) File /home/sites/site7/users/tunedb/2-2-2/lib/python/OFS/DTMLMethod.py, line 172, in __call__ (Object: AddAbcFileLogic.html) File /home/sites/site7/users/tunedb/2-2-2/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: AddAbcFileLogic.html) File /home/sites/site7/users/tunedb/2-2-2/lib/python/OFS/DTMLMethod.py, line 168, in __call__ (Object: AddAbcFileResults.html) File /home/sites/site7/users/tunedb/2-2-2/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: AddAbcFileResults.html) File /home/sites/site7/users/tunedb/2-2-2/lib/python/DocumentTemplate/DT_In.py, line 633, in renderwob (Object: abcfile_read(REQUEST)) File /home/sites/site7/users/tunedb/2-2-2/lib/python/DocumentTemplate/DT_Util.py, line 337, in eval (Object: abcfile_read(REQUEST)) (Info: REQUEST) File <string>, line 0, in ?

ZMySQLDA cannot find _mysql
by Joshua 15 Mar '01

15 Mar '01

Hi I'm on win2k and installed ZMySQLDA as well as the win32 MySQLdb module from Gerhard's ( http://home.t-online.de/home/err666/ ) The mysqldb is installed in my python dir. I can import from the python window just fine, but ZMySQLDA does not find it in Zope - missing _mysql is the message. What do I need to do for Zope to recognize it? I've searched the list but found nothing on win32 and this. Thanks

Python packages (was: RE: [Zope] FTDraw)

15 Mar '01

Paz writes: > Thanks for the tip Dieter, but indeed, the __init__.py is there. > > However, you say that the _init_ is necessary. Is this more of a zope thing? It is being a Python thing: Python before 1.5 only knew "modules". Then, following Java, packages have been invented (to prevent pollution and conflicts in namespace, modules are found in). A package is essentially a (file system) folder that contains modules and other packages (subpackages). You use it in forms like this: import package.subpackage.module or from package.subpackage import module Details in Python's package support document. The problem with this: legacy * of course, modules have been organized before in folders. How to distinquish such folders from packages? Guido descided, that the existence of "__init__.py" does this. If it is there, the folder is a package; otherwise, it is just a folder containing modules. * "*.pth" files They have been invented to make modules organized in folders easily accessible be Zope. Some magic (defined in "site.py") looks for "*.pth" files and extends PYTHONPATH by what it finds there. PYTHONPATH is used to locate modules (and now packages). Through the PYTHONPATH extension, modules could be found even if they have been in subfolders. Using packages and "*.pth" files together can lead to serious problems (although, I do not expect this in your case): It confuses Python's module loader. Normally, it prevents the same module to be loaded twice. But under this confusion, it may load the same module several times under different names. Some modules hate to be loaded twice... Your code snipped "import PIL.XXXX" with the error message "could not find 'XXXX'" suggests, that "PIL" is used as a package and that is has been found but "XXXX" was not found. I cannot remember the precise name, but I think, your "XXXX" should be defined there. Apparently, the PIL found is strange, not what/how it should be. Usually, I would analyse such problems be starting the Python interpreter interactively (without Zope). Under Unix (I always work under Unix, can't help much with Windows): export PYTHONHOME=<Your Zope Distribution Directory> <Your Python used by Zope, usually "bin/python"> import PIL PIL.__path__ PIL.__file__ If "PIL.__path__" raises an exception, your "PIL" is not a package. "PIL.__file__" tells you, where the module/package has been found. If you put PIL inside the "Products" folder (in fact a package), then the above "import" would look like: from Products import PIL Dieter

where zope should be installed
by jacintha menezes 15 Mar '01

15 Mar '01

Hi, Let me kindly know whether we have to install Zope at the root directory of the Linex machine. B'coz When we tried to install zope at the directory 'root/home/pgmtool' Zope got installed but when the ./start was run it gave the error as 'z2.py permission denied'. what may be the problem ?. Do we need to install zope at the root directory only ?. Please throw some light. Thanks, jacintha
