I know you don't want to install a database, but (I assume) that Gadfly is automatically installed with Zope. Jeff

Thanks for all the help guys... Actually, I knew these techniques, but for some reason, they were failing. Suddenly I realised I had a different images folder one level up which was being acquired rather than the images directory I wanted, higher up the tree. Moral - delete temporary folders before they bite you in the ass - and think before posting. Still, maybe someone else will search on this one day, and save 10 minutes of their time ! -----Original Message----- From: Dieter Maurer [mailto:dieter@handshake.de] Sent: 11 February 2002 20:12 To: Gupta, Anu Cc: 'zope(a)zope.org' Subject: Re: [Zope] Newbie question re referring to items Gupta, Anu writes: > Feel stupid for asking this question, but can't work it out...

Custom 404 page?
by Dmitry Litovchenko 12 Feb '02

12 Feb '02

-----BEGIN PGP SIGNED MESSAGE----- Hash: MD5 I didn't find the place to customize 404 ERROR page except in source code. Is that the right approach to patch Zope code? I think no. standard_error_message appears to show all errors except 404 one. Could anyone suggest? -----BEGIN PGP SIGNATURE----- Version: 2.6 iQDVAwUAPGjMUvJfaWAEJLRDAQFdMQX/T9u3W0CIveHLq6DvJ5F4H5YG17RcCz7S eKH0v6qt9zUpE+C/fshd2aH2LK2jmEYGXNNsvQTx11y5+KNY7ncvJqK5VavKbFSD a7hTi1+fW70hxg2eCp9pTVcqqPkC7HIvT/Pf13YUrWhQjvUUUVVDfZYiQNl6QkBi VmBJxnDysE/Y08hXo7sYBoTFCZRgTEeX0XnLNBPwb6JZLY4UJ1Lz3VQ68wu4/31r h5Ynk7T8AhpEYQ58h+M4Y+rab/QZL9Ga =E2xV -----END PGP SIGNATURE-----

Why this does'nt work... being a ZopeBook Example?
by Jose Rivera 11 Feb '02

11 Feb '02

Hi... I'm learning Zope trough ZopeBook and the it's not working like the book shows... Building the ZopeZoo structure and adding the script... of id "navigation" <a href="..">Return to parent</a> <ul> <dtml-in expr="objectValues('Folder')"> <li><a href="&dtml-absolute_url;"><dtml-var title_or_id></a></li> </dtml-in> </ul> It does not list the folders bellow the ZopeZoo Folder... I'm running with this configuration: Zope Version (Zope 2.5.0 (binary release, python 2.1, win32-x86), python 2.1.2, win32) Python Version 2.1.2 (#31, Jan 15 2002, 17:28:11) [MSC 32 bit (Intel)] System Platform win32 (Windows NT Workstation) I tried also in other computer with Windows 98 and also the same thing happened... it does not list the folders... The script of standard_html_header is : <html> <head><title><dtml-var title></title></head> <dtml-var navigation> <body> Other TEST When I make a direct reference to the method navigation... it works OK... but when I display index_html of http://127.0.0.1:8080/ZopeZoo it does not work... and it shows the message "Other Test"... so This scripts is running but not doing what it should... Thaks for any help. __________________________________________________ Do You Yahoo!? Send FREE Valentine eCards with Yahoo! Greetings! http://greetings.yahoo.com

Artificially create a fileupload instance or batch convert ExtImages
by Tim Hicks 11 Feb '02

11 Feb '02

<Gregor: mailed you directly coz you saved my bacon on something very related last time :-)> Is there an easy way to create a fileupload instance from a string? I am trying to batch convert a load of ExtImage files to give them all different sized preview images, but manage_addExtImage() doesn't accept a string. Alternatively, if anyone has a better way to achieve what I want, I'm very much open to suggestions. Here's the script I've got. ---- for old_folder in container.photos.objectValues(['Folder']): container.manage_addFolder(old_folder.getId()) new_folder = container[old_folder.getId()] for extimage in old_folder.objectValues(['ExtImage']): new_folder.manage_addProduct['ExtFile'].manage_addExtImage(id=extimage.getId (), title=extimage.title, file=extimage.index_html(), create_prev=1, maxx=400, maxy=400, ratio=1) ---- Running it gives me: Error Type: TypeError Error Value: open, argument 1: expected string without null bytes, string found <see traceback below> Traceback (innermost last): File C:\PROGRA~1\zope233\lib\python\ZPublisher\Publish.py, line 223, in publish_module File C:\PROGRA~1\zope233\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\PROGRA~1\zope233\lib\python\Zope\__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File C:\PROGRA~1\zope233\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\PROGRA~1\zope233\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: resizer) File C:\PROGRA~1\zope233\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: resizer) File C:\PROGRA~1\zope233\lib\python\Shared\DC\Scripts\Bindings.py, line 324, in __call__ (Object: resizer) File C:\PROGRA~1\zope233\lib\python\Shared\DC\Scripts\Bindings.py, line 354, in _bindAndExec (Object: resizer) File C:\PROGRA~1\zope233\lib\python\Products\PythonScripts\PythonScript.py, line 336, in _exec (Object: resizer) (Info: ({'script': <PythonScript instance at 014B3F20>, 'context': <BTreeFolder instance at 0CC01490>, 'container': <BTreeFolder instance at 0CC01490>, 'traverse_subpath': []}, (), {}, None)) File Script (Python), line 6, in resizer (Object: Traversable) File C:\PROGRA~1\zope233\lib\python\Products\ExtFile\ExtImage.py, line 88, in manage_addExtImage (Object: Traversable) File C:\PROGRA~1\zope233\lib\python\Products\ExtFile\ExtImage.py, line 321, in manage_file_upload (Object: CatalogAware) File C:\PROGRA~1\zope233\lib\python\Products\ExtFile\ExtFile.py, line 371, in manage_file_upload (Object: CatalogAware) File C:\PROGRA~1\zope233\lib\python\Products\ExtFile\ExtFile.py, line 466, in _copy (Object: CatalogAware) TypeError: (see above)
