FAQ: How to add a ZClass
by Ulrich Wisser 14 Jun '01

14 Jun '01

Hello, I know this is a FAQ but I didn't manage to add a ZClass to a folder in DTML although I followed all steps in the How-To. My new ZClass needs only to have an 'id', so I just go with the default installation. Here is what I do: Create a product, name 'tip' In the product create a ZClass name 'kingkong' In folder /admin I have DTML Method 'addTip' which does <dtml-with "manage_addProduct['tip']"> <dtml-call "kingkong_add(_, REQUEST, NoRedir=1)"> </dtml-with> When I call addTip?id=123 I get an NameError. Traceback says Error Type: NameError Error Value: kingkong Traceback (innermost last): File /usr/local/Zope-2.2.5-linux2-x86/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/Zope-2.2.5-linux2-x86/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/Zope-2.2.5-linux2-x86/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/Zope-2.2.5-linux2-x86/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/Zope-2.2.5-linux2-x86/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: dtTipp) File /usr/local/Zope-2.2.5-linux2-x86/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: dtTipp) File /usr/local/Zope-2.2.5-linux2-x86/lib/python/OFS/DTMLMethod.py, line 172, in __call__ (Object: dtTipp) File /usr/local/Zope-2.2.5-linux2-x86/lib/python/DocumentTemplate/DT_String.py, line 528, in __call__ (Object: dtTipp) File /usr/local/Zope-2.2.5-linux2-x86/lib/python/DocumentTemplate/DT_With.py, line 146, in render (Object: _['Control_Panel'].Products.tip.kingkong) File /usr/local/Zope-2.2.5-linux2-x86/lib/python/DocumentTemplate/DT_Util.py, line 337, in eval (Object: kingkong_add(_, REQUEST, NoRedir=1)) (Info: REQUEST) File <string>, line 0, in ?

binary data
by Klaus Herrmann 14 Jun '01

14 Jun '01

Hi *! As i didn't get any replies to my second question: I looks like there is no way of building a ZClass with more then on 1 field for binary data, i.e. 2 or more files in one ZClass? That sucks. Maybe if i do it in Python? But i guess there'd be no way to have a dynamically growing number of binary data fields :-( any ideas? (what i want to do is the following: in lotus notes, you can just drag as many files as you like on a document, and these files are stored as attachments with the document. i need to be able to do the same in zope) regards, Klaus -- Klaus Herrmann <klaus.herrmann(a)goelz.com> Goelz & Schwarz GmbH, Munich www.goelz.com phone:+49 - (0)89 - 544 67 0 22 fax: +49 - (0)89 - 544 67 0 10

Guten Morgen. Before I spend a lot of time to reinvent the wheel, well, has anyone here build a StructuredText to PDF converter with ReportLab? I'd like to provide a string with a STNG document and get a sequence of flowable objects (Paragraphs, etc) back. Anyone? Please... :-) Cheers, Nils

Re: [Zope] binary data
by Geir Bækholt 14 Jun '01

Klaus, use manage_addFile just like you would in a normal folder.. ObjectManager is the superclass that Folder uses to get it's 'folderish' behaviour, so if your zclass inherits from ObjectManager as well, it will behave like a folder when it comes to containing objects.. You can keep files, images DTMLdocuments, other zclasses , - whatever you like in it..... :-) >> >> - when doing this , it will act as a regular folder in most respects >> (as far as containing stuff anyway), >> allowing you to have as much binary data in as many files as you >> want.... >> >> :-) > > that sounds great! > but how do i actually attach the files? addProperty? > i need one file for the constructor, right? i mean, the var "file" has > to be defined when i add an instance. > > thanks! > Klaus -- Geir Bækholt web-developer/zopatista geirh(a)funcom.com funcom oslo | webdev-team

Best way to scale images from Zope besides PIL?
by Chris Beaumont 14 Jun '01

14 Jun '01

I'm building a web application that needs to create uniformly sized thumbnails of uploaded pictures, and I have been trying now for a very long time to get PIL working on my system without success with no luck whatsoever. Is there a better (or should I say working) method of having this image manipulation functionality in Zope? Unless you are willing to spell it out *explicitly* *please* don't give me more advice on how to get PIL working, I give up. I've tried at least ten different helpful suggestions (and tried reinstalling it from scratch three times)..none of them have worked.. I'm currently using the 2.24 binary release of Zope running on Debian Linux (potato) Basically what I need to do is script an external application to resize images using Zope as a control mechanism. The images don't have to reside within Zope (in fact, it is better if they don't..) Thanks.. -Chris
