Haven't tried yet :-) but you give a good enought definition of the problem, so I'm forwarding this to there. More technical view, if anyone cares: What Renderable does is basically define a __str__ method, so that we can control what is displayed when we do <dtml-var obj> (and obj is of a class derived from Renderable). But __str__ is a pure-python feature, so it doesn't get a context (REQUEST etc). Namely, we would really appreciate to be able to tell the name (url) of the object we're a method of :-) []s, |alo +---- -- I am Lalo of deB-org. You will be freed.

This looks like two questions in one sentence, so I'll answer them seperately. MFI exists as a skelatal prototype, the current model is much more advanced then the one you see now, in fact MFI has a whole model unto itself. I will post it on Monday. The objects that PTK come with are stock objects, most of which will be 'ports' of the existing zope site objects. They will change in minor ways, ie, they will use MFI, their interfaces will be more consistent, and their behavior will be analyzed (hopefully by all of you!) to see if they can be made more useful. A familiar rhythm I'm looking for is 1) release an alpha, 2) someone points out a problem, 3) that person, using the model, describes exactly how they think it should work. This doesn't mean you have to be a modeler, but you should be able to look at UML and at least be able to say "Class such-and-such defines this method, I think the method should return X". In fact, this doesn't even need UML, you can do this from the source. The model is to make it easer for us all the grasp the big picture. > - Please tell me that the Membership System and Topics are > still planned... > these are really important. Yes they are planned.

Hi, Michel This model does provide some good info about some of the basic PTK object types and their relationships... I do have a few questions about this: - Does MFI exist now, or are you going to redo the objects that exist on the current zope.org site so that they utilizes the MFI? - Please tell me that the Membership System and Topics are still planned... these are really important. - Does the original model file include information about the attributes you plan for each of the object types? (I didn't see it in the HTML version anywhere) Kevin

help ZCatalog searchResults
by mk 23 Oct '99

23 Oct '99

Dear All. Your help in the decision of one problem is necessary to me. What types of inquiries supports searchResults? I know only variant searchResults (name of a field = a required word) If look at def searchResults (self, REQUEST=None, used=None, query_map = {type (regex.compile (")): Query. Regex, type ([]): orify, type ("": Query. String, }, ** kw): There are inquiries type (regex.compile (")): Query. Regex and type ([]): orify. If probably, give me an example how to use these types of inquiries. Whether a way of search ' tes * ' where * any symbol. If it is possible - how can I do it?. How to use inquiry type (regex.compile (")): Query. Regex from dtml? Thank to you in advance, Sergay.

load_site.py patch2 final
by Oleg Broytmann 23 Oct '99

23 Oct '99

Hello! Attached is gzipped source for heavily modified load_site.py. In this latest patch I added capability to parse HTML files the following way: 1) <HEAD></HEAD> parsed and completely stripped off; 2) <TITLE></TITLE> parsed and stored 3) all other tags inside HEAD are stored separately in a long string; 4) <BODY> stripped off and replaced with  5) </BODY> stripped off and replaced with  6) </HTML> stripped off. On uploading to Zope, saved title used as document's title, other saved tags (from HEAD) stored as "loadsite-head" text (multiline) property. To restore the property, you just need to add new (or modify existing) standard_html_header. Add the following between <HEAD> and </HEAD>:  Hey, DigiCool! Would you like to include new version into standard distribution? If no, I'll publish it on my member page, along with short HOW-TO.

XMLDocument patch feedback
by Anthony Pfrunder 23 Oct '99

23 Oct '99

Amos / Martijn, I applied your patches to the XML Document product but it didn't appear to fix the problem within VisualZope / XMLWidgets. Below is a traceback and associated information. Products/VisualZope/VZManager.py contains one class (VZmanager) which inherits from: * Products.XMLDocument.XMLDocument and * Products.XMLWidgets.XMLWidgetManager.XMLWidgetManagerBase VZmanager implements the following additional methods: * dorender * prender VZmanager is the superclass for the Form ZClass. This ZClass, when "viewed" (ie via URL or index_html) calls a ZClass method "view" which calls the inherited "dorender" method. When the Form instance is "viewed" the following occurs: ************************** Edited Extract of HTML Error Page ********************************** [snip] Zope has encountered an error while publishing this resource.

ZCatalog and indexing DTML methods
by Stuart 'Zen' Bishop 23 Oct '99

23 Oct '99

Greetings. I need to use ZCatalog to index computed values of my ZClass. It seems that ZCatalog will happily call DTML methods and index their output, but the DTML methods are not called with any arguments so cannot do very much. At the moment, I'm having to shadow the output of my DTML methods (eg. return the Id of PARENTS[1] type stuff) in property sheets to achieve the required functionality, but this is ugly. Is this sort of thing possible with ZClasses, or is this where it is worth switching to Python classes? Would it be possible to modify Catalog to do this? I think the necessary section to modify would be recordify in Catalog.py. The first argument to a DTML Method call would just be the object passed to recordify. I'm unsure how to fake up the REQUEST attribute though. Is this the right way to proceed? ___ // Zen (alias Stuart Bishop) Work: zen(a)cs.rmit.edu.au // E N Senior Systems Alchemist Play: zen(a)shangri-la.dropbear.id.au //__ Computer Science, RMIT WWW: http://www.cs.rmit.edu.au/~zen

Detecting Deactivation

I know this topic has come up but I couldn't find the answer. Is there away to detect whether an object is about to be removed from the cache so that one can perform some maintenance on _v_ variables? --------------------------------------------------- - Scott Robertson Phone: 714.972.2299 - - CodeIt Computing Fax: 714.972.2399 - - http://codeit.com - ---------------------------------------------------
