This works almost perfectly. There is one small correction, though: the _prepend method you give prevents regular registration from any later object, because self._append is defined as self._objects.append earlier on; this means that further _append() calls will append to the wrong sequence. A more correct version is: def _prepend(self, object): self._objects[0:0] = [object] Thanks again, Shai.

Folderish documents
by Nolan Darilek 02 Apr '01

02 Apr '01

I'm hacking on ZWiki, trying to create a subclass of the ZWikiPage which acts as a folder which can contain other ZWikiPages. Much of the work for this product is done. It behaves folderish, items can be added, management tabs appear . . . but the contents of the folder don't appear. Instead, I get a message saying something like: 'There are no items in <string>' even if contents are a) added and b) viewable. I really don't know what could be causing this, whether the error is in me, ZWiki, or OFS. I don't receive any errors, but this contents problem has bugged me for days, and I don't have any leads on a solution. What additional information can I provide? Can anyone offer any suggestions? Thanks.

I am astonished that it worked at all: "dtml-in" requires a sequence, but "PARENT[-1]" is not a sequence but an "Application" object. Did you try: <dtml-tree "PARENTS[-1] branches=objectValues"> &dtml-id; </dtml-tree> Dieter

I *believe* > ZPT should be architected to handle this issue better, but DTML Methods > never were. It is quite easy to make DTML Methods "Content-Type" aware: Give it a "content_type" attribute. All the machinery is present to provide the correct Content-Type HTTP header, as soon as there is a "content_type" attribute. The following two external methods can manage a "content_type" attribute of DTMLMethods (for DTMLDocuments, a standard property works well). def getContentType(obj): '''return content type of *obj*, 'None', if not available.''' o= getattr(obj,'aq_base',obj) return getattr(o,'content_type',None) def setContentType(obj,type): '''set content type of *obj* to *type*.''' o= getattr(obj,'aq_base',obj) o.content_type= type An alternative is to give the DTMLMethod's extensions. If, e.g., a DTMLMethod has an id with a '.txt" extension (suffix), then its default content type is "text/plain". Dieter

Perl + Python = Parrot?
by Jonathan 02 Apr '01

02 Apr '01

Hi all, Just reading a press release on python.org: Perl and Python to begin joint development http://www.python.org/parrot.html I thought Guido and the rest of the Python crew worked at Digicool, but apparently he just accepted a job at ActiveState, together with Larry Wall. Where is this going? If Perl and Python are merging in the near future, we'll need to find another language to fight our language wars with ;) C# maybe? :) Cya Jonathan

[Q] The Book's examples are working sporadically for me
by Carl David 02 Apr '01

02 Apr '01

I think I've got some kind of permission problem, since the examples in the "Book" concerning <dtml-tree> and <dtml-in expr="objectValues('Folder')"> etc., work on some folders and not on others. Can someone clear this up for me so that I can get consistant behavior? Thanks. Carl David david(a)uconnvm.uconn.edu
