create folder within folder-object via DTML
by Ingo Assenmacher 14 Feb '00

14 Feb '00

Hi all! I want to automatically create some instances of default objects whenever creating a specific folder-object within the zope-management interface. This is what I do within the constructor of a folderish object: <dtml-with "termin.createInObjectManager(REQUEST['id'], REQUEST)"> <dtml-call "manage_addFile('invitation', '', 'Einladung')"> // (works) <dtml-call "manage_addFile('protokoll', '','Protokoll')"> // (works) <dtml-call "REQUEST.set('id', 'material')"> <dtml-call "REQUEST.set('public_view', '1')"> <dtml-call "REQUEST.set('public_upload', '0')"> <dtml-call "REQUEST.set('owner_delete', '1')"> <dtml-call "REQUEST.set('store_in_db', '1')"> <dtml-call "MaterialFolder_add(_.None, _, NoRedir=1)"> The last one works, too, BUT the folder is NOT created within the folderish "termin" (unlike the "add_files"). This is what I want: termin (folder) | invitation (file) | protokoll (file) | material (folder) And this is waht I get: termin (folder) | invitation (file) | protokoll (file) material (folder) How is this? Thanks for any help! Regards, Ingo ------------------------------------------

Arrggh, more namespace confusion ...
by Darran Edmundson 14 Feb '00

14 Feb '00

I'm on the tail-end of another 48-hour Zoping marathon but just when I can see the proverbial light - click(). Arggh. I've pared my current problem down to: root spam (DTML method) folder1 folder2 where spam contains: <dtml-var "REQUEST.set('mylist', ['folder1','folder2'])"> <dtml-in mylist> <dtml-with sequence-item><dtml-var id></dtml-with> </dtml-in> My aim is to loop over mylist pushing sequence-item onto the namespace stack, ie, <dtml-with folder1><dtml-var id></dtml-with> <dtml-with folder2><dtml-var id></dtml-with> I've toyed with every version of the <dtml-with> tag I can imagine but to no avail. Can someone please explain the source of my confusion. Cheers, Darran.

subclassing across products?
by Ingo Assenmacher 14 Feb '00

14 Feb '00

Hi all! I have developed a container ZClass. Within I created another ZClass which presents a meta-class for file-uploads. Now there is the case that I still want to upload diffenrent things and let them be described by an extended meta-class object. I have developed another product which uses services from the upload product. There I intended to create an extended ZClass derived from the meta-class. But unfortunately the BaseClass listview does not allow to select classes from my other product! This is what I have: Product A | class 1 (container for class 2 objects) | class 2 (additional information objects) and this is what i want: Product B | class 3 (subclass of class 2, additional properties) There seems to be no way to subclass from class 2 here, is there? Can this be done, and if, how? Regards, Ingo ------------------------------------------

Catching a Zope DateTime Error
by Matthew Parslow 14 Feb '00

14 Feb '00

I have a number of variables of type :date. they get converted to ints on the target script, which works fine, but I need the script to know whether it's a valid DateTime. I have tried catching an exception, but it doesn't throw an exception, it creates a ZOPE error. It doesn't seem to work in a dtml-if statment either. I was wondering how I can handle this error. Regards, Matthew Parslow.

probably an obvious one - zope just returning '<Module 'Main'>'
by Anthony Baxter 13 Feb '00

I've got a zope 1.10 installation that's suddenly broken - it's now returning <Module 'Main'> for /, and can't find anything else. I've had this before, but I'm stuffed if I can remember what it was. (it's way too early on a monday). help? anyone? Anthony

Crashes after ftp access?
by Daniel Yoo 13 Feb '00

13 Feb '00

I'm really new to Zope, so please excuse my ignorance. I've been playing around with Zope, and I tried using emacs with angeftp. However, every time I try to connect to the ftp server at 8021, emacs complains that it can't connect. Afterwards, zope dies and I have to restart it again. Has anyone else encountered this? Thanks for any help!

Re: [Zope] How-to generate an XMLDocument automatically ?

Hello Matthieu, To get you started, you may want to take a look at the paper "Creating XML Applications With Zope": <http://www.xml.com/pub/1999/12/zope/index.html>. HTH.

Re: selection list confusion ...
by Darran Edmundson 13 Feb '00

13 Feb '00

Thanks Jim, >If you are doing this within a ZClass, you can put Choices on a >PropertySheet, then refer to it as > ><dtml-in Choices> As I understand it though, Zope does not have class variables. If Choices is on a property sheet each instance will have its own copy which seems like needless bloat. Ideally, what I'd like to do is either of the following. Imagine I have the following ZODB hierarchy: root Control_Panel Products MyClassProduct MyClass Properties - MakeChoice (type selection) globals - GetChoices (DTML method) 1) I would like the value field of MakeChoice to call the DTML method GetChoices which resides in the globals folder. As it stands, GetChoices needs to live in the root in order to be found by acquisition. Is there a way around this? Alternatively, 2) I would like GetChoices to live in MyClassProduct. This does not work for reasons that elude me. One would naively think that since GetChoices is in the same location as both the class addForm and the constructor, it would be found by acquisition. It isn't. Any clarification of these issues would be most appreciated. Cheers, Darran.

Re. Policy -- Docs link to source
by Jerry 13 Feb '00

13 Feb '00

The notion of using links in documents to point back to Zope source (and possibly vice versa?) may seem obvious, especially with respect to a Web Centric project like Zope, but it presents a bit of a puzzle. On one hand, Zope brings us a new level of dynamic hypertext, with lot's of wonderful extensions, such as the Catalog, to aid searching, etc. On the other hand the urge to deploy this very technology for the purpose of enhancing the "acquisition" (?!) of Zen smacks us right up against the immaturity of the Web itself. How can the links possibly be kept "fresh", especially with a rate of development as rapid as Zope's? Is "freshness" the sole criteria? What of the historical value of archival code, and documentation? Temporal data integrity may not seem mission critical in this particular instance (Zope as software project), but there are plenty of applications where such criteria are vital. Bobo gave us persistence, Zope gives us integration. Are we ready to tackle the nitty gritty of managing non-tabular data, randomly shifting in four dimensions? Now appears a glimpse of the depths that Ted Nelson addressed in the Xanadu project. It may be time to review the sort of solutions that Xanadu actually applied to tracking documents changing over time. Does anyone have a complete collection of "Byte" from the 80's? There was an excellent article about Xanadu, and a fair exposition of the algorithm. This is getting very interesting!
