looking for DTML Property examples
by Jason Cunliffe 17 Aug '00

17 Aug '00

Hello I am looking for some basic examples on using Properties in Zope. For example: How-To write methods which put and get properties, and with these examples of accessing properties via URLs directly as wellas via custom methods. There must be a ton of examples _somewhere_, but somehow, I can't seem to find them and th ORA book is not out yet [praying hard for great index and LOTS of small examples thourhgt the text]. Thanks in advance for any links - Jason ________________________________________________________________ Jason CUNLIFFE = NOMADICS.(Interactive Art and Technology).Design Director

getting base classes's (super class) _properties tuple
by Daniel Rusch 17 Aug '00

17 Aug '00

Say I have a fully functional (and more importantly, working) Product will call A. I want to extend this Product's capabilities so I wish to derive another class from it, call it B. No problem, class B(A): ......... now in class B I want to add a new property. Is the a way of getting the base (super) class _properties tuple and just adding the new one to it. Since a tuple is an immutable object I can't do this: _properties=A._properties.append({'id':'RenderStandardHeader', 'type':'int','mode':'w'}) Any thoughts ???? DR

Amazing Disappearing Self

Hi Zope Fans, Has anyone seen a case where acquisition works, but only in the topmost folder? The site I'm working on shows no problem on a test server, but upon moving to a production server any URL pointing to a subfolder, or a document contained in a subfolder returns an error (below). The production server is Red Hat linux, Zope 2.1.6 A Proxy (running on a separate server) re-directs URLS to the top folder of the Zope tree, just below "root". The oddest part is that elements available in the "root" (standard_html_header, and other elements called within) show up on the same "page" as the error message. It's as if Zope is working partially, but after displaying all the elements at the top of the tree, the silly document can't find itself . . . BTW, the raw URL (as seen in REQUEST) contains lot's of cookie garbage which may be causing the problem. I have added something like <base href="&dtml-relative_path;"> as suggested in some "How-Tos" at Zope.org. This got me to the point of having the top folder render correctly, which was better than I had seen up to that point. Alas, that's where progress stopped altogether. On the test server everything "just worked", the way you sort of get used to with Zope . . . The worst part is that some of the errors I'm seeing spill the guts of the cookie all over the browser screen. BTW, what does it take to get standard_error_message to actually do what the dtml implies, to substitute the contents of an error_message object, where it exists? Thanks, Jerry S.

Re: Bug in <dtml-in size=1>

http://classic.zope.org:8080/Collector/1056/view Back on Februrary 14th, I submitted this bug, however your account of it is much better than mine. It has been pending for quite some time, but either way I never found a good solution to this problem. There is some sort of work around involving continuing to present next buttons with sequence+1 until you get to the end of the sequence. -Mike > Hi, > > I am working on a project with Zope.

zCatalog and subobjects
by Menard.Jean-Francois＠hydro.qc.ca 17 Aug '00

17 Aug '00

(Post #2) I'm trying to search a zCatalog to find all the objects containing a certain type of sub-object. Right now, I use a dtml-if inside the result loop, but the result count is obviously wrong. There must be a better way to do this, right?

Use "self.whereever._setObject(id,newob)" to place it in "whereever". Of cause, "whereever" must be acquired by "self" for this to work. You would use "getattr(self,wherever)", if "whereever" is not a constant name but an expression, e.g. passed in via a parameter. Dieter
